Over an hour of Dave unboxing the new GW Instek GDS-2000A series VPO oscilloscope, and first impressions on trying to use it. Some comparison to the Rigol DS2000 series are also made.
This is a not a proper considered review, it's just a hack'n'slash at playing around with it out of the box.

Hi I Just got this into the lab and I thought we'd do an unboxing and a first impressions video. It's the new GW Inc GDs 2000a series not be not to be confused with the old 2000 Series This is the latest A model and it's a rip snort. The one I've got is the GDs 2304a and it's fully optioned up. It's the 300 mahz uh Version: Uh, four channels.
That's what the four means. That's what the three. so three means 300 MHz four means uh, four Channel Version: It's got the logic analyzer dual Channel Function Gen: It's got everything. Fantastic.
One of these new Modern Scopes that um, pretty much come up to uh challenge the Agilant um 2000 series Scopes which is it's direct competitor. A couple of years back when Agilant released the new X Series, they had the market all to themselves with the building function gen and the high waveform update rate and uh, everything else made an absolute killing. But now there's a few of these um, uh, modern scopes on the market that are, uh, nipping at the heels. so let's check it out.
I Have not used one before. this will be a first time I unbox it, it's not open yet. First time I've ever used one. um Ball Park prices here I Just got these from uh, Tequipment.net who have, um, some excellent Street prices.
So these are Street prices They Don't Really um GW inch Don't really release um Ual prices as as such, so you really got to go by uh Street Prices: These are the two channel models. Starts from $836 so um, direct competitor to the Ryol 2000 series Um, and also their main competitors are the Ryol 2000 Uh series and also the Agilant 2000x series as well. So uh for this 70 MHz model 836 Very affordable up to the 300 MHz model for 2385. The 4 channel um, it looks like you're pay paying about an extra H What is it? $600 Odd doar there.
Yeah, So 600 bucks for the extra two channel could be very worthwhile. That's a huge difference between the Um Ryo 2000 series. For example, they don't offer a 4channel uh option. So really, you know if you're after four channels um, you know that's not really a Uh consideration and uh, so, uh, extra $600 odd do there roughly for the extra two channels and the options are very affordable.
Gpib is pretty expensive at 400 bucks, but check it out. the function generator $245 oh, that could be an absolute bargain duel Channel as well and the 8 channel logic logic analyzer 570 bucks. A bit on the pricey side, but certainly not as um expensive as some competitors. So let's uh, crack this thing open and have a look.
uh Goodwill um, who they used to be called now they're GW Inc or Goodwill in deck Um Goodwill have a quite a long-standing reputation I've used Goodwill gear for a 20 years ever since I've been in the industry. Really, they've got a pretty good reputation for having Um Fairly reliable and uh, well made. Um, they're one, of, you know, always been one of the better um uh Asian manufacturers of uh tesk or Tes or one of the first really good quality uh providers. So uh, really? Um, they do have a good rep. So I don't expect this to be a, uh, a cheapy by any stretch of the imagination. I Expect it to be well designed and well built. We've got the uh logic analyzer. There we go.
What do we get? We get a little manual. we got a little cover for the module at the back. Oh, we get some test Clips Little Mini Grabbers And we get there. we go.
We get the probes. So excellent. Let's have a look at this and so yeah. I Got high hopes of this one.
Um, by all accounts, it's fairly new. It has been on the market for a little bit um, but it's fairly recent. so there you go. That's what you get for your 500 odd bucks.
You get. it looks like there is some circuitry, probably some buffer circuitry or something inside that by the looks of it, feels a bit plasticky and cheap. Doesn't really feel you know it's not quite up there to the agilant uh probes, that's for sure. Um, so anyway, they all uh, numbered.
very nice I like that colorcoded uh the test Clips were little mini Grabbers they're all I assume their matching color code So that's quite nice. So there you go. If you're after a mixed signal um scope then uh, you know eight eight channels is probably all you need on this kind of thing. Um, when you're talking about uh, 16, you know when you try start trying to get 16 channels on an eight I think this is 800x 600 screen then really? you know I mean it's a bit hard to, it's a bit hard to use.
You're better off using like a PC based logic analyzer then. So I probably wouldn't recommend anyone get like a 16 channel analyzer on a on a mixed signal scope. really? um unless you got a really huge uh screen, we got some there we go. 200a series it looks Happy by the way.
um this was sent to me by um Edward Pan Direct from um GW insect so thank you very much. uh Edward they got lots of new stuff. um they said I can review um pretty much anything I want? So if you want to see some of the oh 3 gig Spectrum analyzer, look at that RF and Communications tester all sorts of stuff and uh, we got a new 25 Meg arbitary waveform generator, some loads power supplies, all that sort of stuff. and by the way, um, all this GW Inc stuff designed and manufactured by them not OEM or rebadged under any other name.
So um, you know you will not find this scope. uh, under any other model proper. Australian plug Beauty All right I Like it. We get the software.
yes it does hook up I'm not sure if it's like um LXI compliant or anything like that, but uh, we will. We got a couple of probes in here. an extra two probes presume I they they're different. Are they different I know no they could be the same probes but uh we'll take go out and have a look and what else have we got.
The box is a bit crusty. it's uh, you know it's not the best, but ah it doesn't matter. All we care about is the scope. inside. it's quite well protected with its uh big. that's it. Yep, nothing left off. we go.
sorry about this because this is just, uh, filmed all in one shot. The camera angles not going to be great ideal, not going to be ideal. The audio is not going to be ideal. so oh, it's a big beast.
Wow, hey this is pretty large folks. Hang on First thing I got to do not much of a smell, not much of a new product smell on that I Got to admit yeah and here it is. It is a bit of a beast. It is quite large so uh I'm not sure my first impressions are that I don't I first impression Really, it's a bit ugly.
I've got to admit. um, let's peel that off. There we go. Protective: 300 MHz 2 gig samples per second uh 2 Meg uh waveform uh two 2 Meg uh sample memory what else is it got? 800x 600 screen U you know all the usual stuff sign X on x um uh, 80,000 waveforms per second Very fast updating on this thing.
It's got V or what they call their visual visual persistence oscilloscope so you know, equivalent to um, all the tectronics and the agilant one and the Um one used in the Ryo or basically any sort of $800 class um scope Plus or $1,000 class scope has basically analog like waveform intensity, uh display and this one certainly does have it. uh uh, you know, uh, what else? uh goes down to 1 molt per division I'm assuming that's uh, real and not just um, uh, like hared or something like that I don't know. Anyway, we'll find out. but uh, definitely download the spec sheet.
the uh Logic Analyzer 500 Meg samples per second 200 mahz record length is 2 Meg on the logic analyzer as well. up to 16 channels, blah blah blah. Anyway I first impression is is that that it's a bit ugly? sort of. They haven't hired a it's a bit toy like um, they haven't really hired a proper industrial designer to, you know I mean it just doesn't look as nice as for example and it's much bigger than for example the new Ryo 2000 series.
I mean check it out, it is absolutely huge compared to the Ryo 2000 series and it's just you know, this is much nicer design, more professional, more industrial designed. I you know it's a colorcoded. this is very Bland and just yeah I Don't know I Think they need to hire a better industrial designer? It just doesn't look as professional as the Agilant one or the Ryo one. Um, but anyway I mean looks uh yeah I don't know it just I Don't know.
Does anyone agree with me? Please leave it in the comments. But anyway, check it out w a lot of functionality on the front here. We've got our four channels of course. I am assuming I haven't seen a photo of the two channel one.
I'm assuming that um, the knobs and buttons aren't populated so you get sparse and then you get blank plates there. No, you cannot upgrade. if you buy the two channel, you can't upgrade to the four Channel Just like the other scopes on the market. and also, um, very disappointingly, you cannot upgrade the bandwidth. The bandwidth in this thing is set via software. I Have had that uh conf firm So when you buy the 70 MHz scope, it does actually have a 300 MHz front end in it, but it's software limited down to uh 70. Um, but you cannot buy unlike the Agilant Scopes you can't buy the software upgrade for it and I think that's a mistake and you can't do that on the Ry gos either. I think that's a big mistake.
They should be. You know, take our money please. you know so that we can upgrade. you can buy a 70 MHz model.
Now if you you know if you can only afford you 800 bucks or whatever and then as you know you might need the bandwidth down the track up, you know, um, buy the upgrade for it. So I don't know why they're not offering that. both GW Ins and Ryol I have no idea what's going on there. But anyway I don't like look at this look.
it's like very toy like look at H Yeah the vaults per division gets bigger as you go in that direction. Oh oh it's a bit wanky I don't know the kind look. pink button and it's it's bland I just don't I Don't get you know. doesn't feel professional to me but it does feel good quality I do like the feel of the knobs.
they're indented the variable ones, not time division is they're not pushable. Look, they don't have a secondary function. Oh I don't like that I really like the Scopes that um, have a secondary uh I tried to pull like the trigger level I'm you know, like that's old school analog stuff I Just instinctively tried to like pull a knob to see if it came out. they don't have that on digitals anymore.
Unbelievable old school habits kicking in there. but yeah, like I'd like to be able to just you know, push that in like I can on the Um Riyo and the Agilant ones and then it just automatically centers the position and stuff like that. push time. Push the horizontal position, it automatically centers.
You can't do that on this scope. That's pretty disappointing. They've cut cost there, don't like it. but yeah, the screen's Prett big.
It's not the wide form factor, it's more of like the 43 aspect ratio. Well, it's 800 by 600 so it's a decent resolution. uh screen anyway. dedicated hard copy button soft keys down there soft keys on the side menu off button I Really like that to get rid of.
We'll see that when we power it up. But anyway, on the front external Triggers on the front, we got three demo signals. not one, not two like you get on the Agilant, but three demo signals. Awesome.
There's your ground. There's your USB uh host on the front, the uh logic analyzer interface so that just uh plugs in there. it's obviously just a right angle connector on the main board or something like that and dual Channel waveform Gen: Awesome! um uh, ryol are coming out soon with um, it's been talked about on the Forum coming out with a new Uh version of the 2000 series which will have the function gens uh built in and also apparently a logic analyzer version soon. but this thing is available now. dual Channel Function Gen logic analyzer and that's great. I mean a function Gen for Jeal channel only 200? What is it? $245 That sounds like a bargain. Nice big oh clunk and onoff switch I Really like that. feet.
Um, it's not that heavy. It's not that heavy. Feet are okay. We got some rubber at the back under there.
That's all right. QC Inspected. Thanks for that. Yeah, they're all right.
They're passable. Um, unfortunately. I Just noticed no Um Auto probe interface at all. So you've got to select the Uh Time 1 * 10 manually.
That's a bit of a bummer. Like you know, when you're sort of, you know if you're paying, you can pay two and a almost $3,000 for this thing and you don't get for the 300 MHz one and you don't get Auto probe interface I Mean gee, you know I can expect it on an $800 scope on the 70 MHz model, but on a Uh a 300 MHz one when you, you know Auto probe interface would have been nice, but you really only get those on the main play like the big players like your agilant and your TCH anyway. essentially. but there's a lot of functionality built into this.
Really like it. Um, the location of the Uh controls the vertical uh uh position. Start the vertical scale. vertical position.
all in line with the BNC the colorcoded I assume Yeah, we've got the colorcoded Rings which come with our scope probes. They do look like matching colors yes, so Yellow, blue, and I assume that the onscreen waveforms will be the same color. We need to power this up 50% Trigger point Handy Menu: Force Trigger Great! Um Auto Set Run Stop s dedicated single button Excellent. Default mode Terrific! So we got a Acquir utility test, cersion measure display or it basic.
You know it's very, um, very similar to most other digital scopes on the market. You know you use one. you can pretty much pick them all up within you know, 10 minutes of using select various options and then you got a dedicated Vari variable knob there. Um, but the knobs feel okay a little bit.
It's definitely not up to the class of the other ones really and they're not pushable. bit annoying. anyway. nice is carry handle on the top there.
Let's have a look at the back. We have modules Taada so we have slot one and Slot two obviously for uh, how do you get that out I don't know, bit hard no what do you have to do? Lock unlock Oh there we go right? Yeah, Okay, there we go. They got oh oh, there's actually stuff in there. There's circuitry in that.
Check it out. There's a Sh I can see a shield can inside that and I can see the ventle I can see through the vent holes. they got circuitry in there, so what are these? They're not. Oh, here we go.
Uh oh sorry, yes, uh. Function Gen Module: Okay, right. So when you buy the Function Gen, they obviously ship you the Function Gen module for your 245 bucks and you plug it in and that enables your function Gen. There's a lot of connectors on there. There's a lot of pins that looks like a PCI um type um slot actually. Um, so yeah. obvious. I I Hope it's just more than like a um E prom in there or something like that to enable the option.
I don't know whether or not I'll have circuit. We have to actually take those modules apart and this is the logic analyzer. Is it? No, Yes. Eight Channel Logic analyzer.
There you go. Presumably you can buy the 16 channel one as well. but so that's 570 bucks for the logic analyzer. You get this and you would get your probe.
um as well. So there you go. That's uh, not. Well, you know.
I don't mind that at all. At least you get something physical for your money rather than just a software option. You know you buy the software option on the Agilant, for example, and they just send you a license code and you plug it in. At least you get some physical Hardware Like you feel like you're getting your money's worth for your 245 bucks, you plug it in and uh, away she goes.
so that's rather. don't mind that at all. It's uh, it's pretty good. Got a Kensington lock um Universal input voltage of course.
okay, calibration input. there's a go Noo open collector output. It doesn't say it's got a trigger output, so measuring the update rate of the display on this um may be a bit difficult. Rs232 um I presume it's not isolated, but uh, that comes standard and uh USB um host and uh device as well.
Um I think you can get an Ethernet can you get an Ethernet module for this thing? uh yes, you can get Ethernet and um SVGA sorry I forgot to get that in my price list I don't know how much that is, but that's the uh DS2 Lan module as well. So yeah, um, a shame it's not built in. Would have been nice to have ethernet uh built in as standard, but anyway, it does have USB so you can hook it up to your PC It comes with the PC software I believe that's free for uh uh, control. Not sure how good it is, but uh yeah, the carry handles a bit cheap.
Overall it's it. Seem it feels built down to a price. That's my first impression. Geez I've been rambling on for 19 minutes straight here on this thing.
But anyway, um, enough of the jibber jabber. Let's uh Power this thing up and uh, hopefully we won't release the Magic Smoke and oh here we go. One oh time that oh I missed it. but there we go.
GDs 2000a series. oh sorry, the uh camera is just gone Auto uh contrast there. it's taking its time. Yeah, it's taking its fat time here.
So I like the it's surfing, we're up to 25 seconds. almost 30 seconds to power that Beast up Heard some relays go clunky clunk and uh, we're in. We're in like Flynn All right, but that that boot time is a bit long. it's on par with the agilant I think so. eh, you know, modern Scopes They got a lot of uh, software and operating system stuff building. The first thing I see notice is's a lot of blue space around here and really small from you know I'm standing, you know, 3/4 of a meter back or something. almost a meter back and I'm having a hard time reading those down there. They're quite small, quite small font and everything like that.
So there you go. 10 m 1 molt per Vision There we go, seems reasonably responsive. See, you can't just push that and put it back in the center I Really like that on the other brand Scopes but that seems to be its noise floor folks. So three four, there we go.
Oh actually it looks like bigger means more gain of course. so you would think that you know the nice Big Dot there actually corresponds to hang on. There we go, look at that. Very similar.
There's our four traces on 1 molt per Division and we can ground that I'm not sure if that's just I Didn't hear a relay click between DC AC and ground? Hang on. No. I don't hear a Reay click so that could the ground. Could just be a software uh, grounding thing.
It may not actually be a physical grounding input impedance. Can't change it. Um I don't know whether I Don't think it has a 50 oh ohm option. So why even put it there? Why even have it there if you're not going to, uh, offer 50 ohm impeded night? Yeah.
1 Megga ohm Standard Uh 1 Megga ohm only uh 16 Peak 16 puff. um input capacitance? Um, oh, by the way, here's a a bit of a trap. It says right here. yeah, little Asteris, read it.
When the vertical scale is set to 1 molt per division, the bandwidth limit will be set to 20 MHz automatically. Aha. So right down at 1 molts. That indicates of course that it does have a true 1 molt per division.
Uh, vertical range. It's not just um, scale down or something so but you only get you don't get the full bandwidth. so you buy a 300 MHz scope. you can't use your 1 molt per division.
So bit of a trap there. Uh. vertical gain 3% yada yada yada 300 volts Peak All fairly typical. So there you go.
There's our well. I don't know what can we do with it I got to start probing signals and around I might have a go with some uh demo. Oh DQ Okay, we've got DC attenuation set to Time 1 * 10 Ah, you don't have the ability to set. Oh yeah, there we go.
that's pretty handy I Rather like that actually, we zoom into that like you you put your vertical. oh how do we get the men menu I Guess you just press any. how how do I get that up I didn't see how I actually got that up I was just randomly. uh poking.
How do you get the vertical option function Gen 2 DVM It's got a build-in D DVM On there we go. It's got a digital voltmeter option similar to the Agilant one which you pay extra for on the agilant, so it looks like you presumably get that uh, built in function Gen 2. Now we'll have a look at the function gens later, but menu off option. How do I get that vertical like there's no menu button. it's just You' think channel one would turns on our channel. oh it's down here, but we had something up here before I don't know Anyway, um invert bandwidth limit 20 MHz that's it. Oh, it's fixed there. We go there.
we go full. So when we're on 2 Ms per division, yeah, we're on 2. MTS we're can have 200 MHz 120 uh, bandwidth limit or full 300 MHz on this particular model. So menu off and uh, all right, what else? Horizontal expand by ground bandwidth full Voltage prob Oh there we go right.
Voltage probe. That's where I hit it. People are probably screaming at me at the moment and I like the fact that it's just got a fixed x 10 there because that's the you know that's the most often you're going to switch between times 1 and time 10 all the time. so that's just handy to be able to.
uh, handy to be able to do that. Doesn't have the times one though to switch back, but you can go down to oh, look, you can set Dou 01 Wow! The attenuation Factor 20 100% 200 up to a th000 times. That's a pretty impressive range for your auto attenuation factor I Really like that. So if You' got an amplifier on the front end, you can really turn that down and get an accurate uh value on your screen here.
and current as well. You can set it for current probes too. Very nice. 50 volts per amp, 5 m volts, 5 milliamps per volt.
Nice. look at that. I Rather like that. Okay, thumbs up to that.
So what else have we got? Measure Menu Statistics: We've got our reset statistics Statistics on. No measurement exists. Add measurement first. thank you very much.
How many standard deviation, mean, and standard deviation? How many samples do you want? Nine seems to be slowing down there with the statistics on. Hang on. No statistics are off, but uh, it's sort of a bit. It seems a bit jerky there on the on the display of that thing.
so I'm not sure. Not sure what's going on there at all. Let's do the Acquire button and there's our sign X on x Yes, you can equivalent time sampling or sign sign X on x XY Mode triggered XY Mode Oh there we go. Look, you can get XY mode and you can get um uh, regular, um uh YT mode as well.
Nice. Very nice. Okay, pretty impressed with that. uh test there dedicated test button in app.
Oh, here we go. What do we got here? Hard to read wrot I don't like the blue. the blue is a bit I All right. So it looks like you can install apps in this thing, but it only has two.
It's only got a driver app and a go Noo app. eh, whatever. I don't know I have to maybe check out the website or uh, look at the manual for that. But anyway, that's uh, time per division.
it seems a bit slow and it just doesn't seem very fast at all. Um, our horizontal 5 NS per division? Let's uh, acquire. Hang on. All right now. let's plug the function gen in here and I've got this set to uh Zoom mode actually. let's Oh there we go. Turn that off and on. Oh, we got some.
There's something residual there on our uh on our input from our function Gen. Seem seems a bit slow. It's certainly not super quick. That's the impression I'm getting so far.
But anyway, let's give it the benefit of the doubt. Um, we got math. One thing I don't see on here actually is: where's the function Gen? Like the waveform Gen Button: There's a test button like there's no I expect when you got this sort of functionality. like, where's the you know logic analyzer button? Where's the Um Function Gen button I Don't see it at all.
How do you turn? It's not immediately obvious how to turn demo out. Okay, we got our demo signals great. Okay, here's our system stuff for those. Oh, look.
transparent menus. There we go. Terrific Firmware Version 1.4 Okay, yeah, the logic analyzer's got its own firmware. The Function Gen's got its own firmware, so there is probably circuitry inside those modules.
Um, I'm assuming I'm running Um Scope Firmware Version 1.14 Uh, at the moment. So for those playing along at home, but where is? maybe I'm just not seeing people screaming at me. But like, where is option Here we go? Option? Of course. right.
Option. Function Gen: Well, where's Function Gen One? right? Where where is function? It's got Function Gen 2 DVM right? So we got our Function Gen: Here's our frequency. There we go: Amplitude: 3.08 volts Peak to peek. Yeah, yada yada.
How do we I Assume that's just going that's already on. Is it? Yes, it is. There we go. So why is there no function? Gen One: I Don't get it.
Anyway, that's that's weird. That's there's a little little bit of a lag there the first time you spin that knob. Little bit of a lag, but otherwise, um, we're going to get any Alis in on that. No, we have to.
uh, turn that up in frequency. obviously. So let's go up to, uh, how do we adjust a frequent look Select: Ah, okay, we're selecting that digit down there and it's not even incrementing that digit. What the I mean I've got to zoom in on that for you to see it.
But uh, it's it's like you can see that that digit there is highlighted. Oh here. No, not not supported under this mode. Yeah, how do I go ACR Like oh oh, there we go.
Oh okay, right. So we're selecting the digit and then we' got to select it and then go up. Oh, that's a bit painful. 5 MHz There we go.
It looks like 5 MHz is our maximum frequency. We're not going to get any. Ah yeah, there we go. Hey in, look at that.
Yep. So if this thing does have any Alis in it, don't work folks. So there you go. Just be careful with that.
That's a 5 MHz signal and uh, 50 100 milliseconds per Division and we get right down. And yeah, Al in that's not good. Don't like that at all. Any modern scope should not Alias Like that. Don't really like that. But the way you've got to select the individual digits I don't really like that. That's pretty painful. So you got to press select, move your cursor over and and then and then press select again.
Oh how tedious. There we go. How very, very tedious. I Don't like that at all.
Much prefer the agilant. uh method. where yeah, the variable you can do fine or course variable control. that's just a no user interface fail I'm afraid now.
unfortunately. uh for you, 245 bucks. I Still haven't figured out how to get the second channel on the function? Gen working and we're You know there's no AR capability by the looks of it. there's just.
you know. no modulation capability. All you've got is your sign. Square Triangle? You know? Incredible triangle.
Hello. Where's our triangle? Hello. Oh there we go. Oh sorry.
it switched back to one. Hey, did that switch? Look at that. It switches. It's set to 3 mahz there for sign and you switched to square and it drops, drops down to a kilohertz.
it's re. it's default reset the frequency. Why? That's ridiculous. Unbelievable what the H that I mean you? It saved it for sign.
Yeah. I Guess it's a feature, right? They've had to deliberately do that cuz they've saved it for the sine wave and the square. We can clearly like a 21. Kilz There we go.
So if we jump between sign and square, it remembers that. Which is, you know? um, great. I Guess it. They designed that as a feature, but I find that more annoying I'd rather have switch between s square and triangle and keep the same frequency and presumably um.
amplitude as well. There we go. Look the amplitudes change and the frequencies default for each one. Ah no.
I don't like that. I know I I'm pretty sure they've done that deliberately. so it's supposed to be a feature. but I think that's a fail.
Um, but that's just you know that's a personal opinion thing. So oh boy. I Keep thinking that's the horizontal knob up here unfortunately. I Keep keep getting it confused.
I Think that's the horizontal. it's not. And so that's our Um 2 Mego memory by default: Acquire Mode acquire I Would have thought you'd get more options for the acquire menu than just the XY mode. Oh, they're all down here.
I Keep looking here. I Keep forgetting. All right segment. It's got segmented memory code.
record length Auto What you can't change? Oh no. Auto and short. What short memory? How? I Guess you'd have to look up the menu. Was it like 10K or something? Furra Done it again.
Use the wrong control but you got Auto memory and short memory. Well at least you can change it. I Guess if you want faster waveform updating rate I Guess you're going to set it to short although yeah. I I don't know H Not too happy there Sample: ah mode. Here we go. sample Peak detect Mode Excellent. Has a peak detect mode. Terrific.
Some Scopes actually don't have that digital filter on okay, digital. Okay, so we can filter out their okay, we can set our filter frequency there. It looks like only in fixed increments. It looks like you can't change that, which is a bit of a bummer.
Even the cheap Ryol can do that I think so. but hey, at least you have some digital filtering capability. I Guess that's going to be based on your time base. Um, so you'd expect.
Yeah, you can actually see that change when we change our time base there our digital filter frequency. So H at least it's got a you know, rudimentary. so yeah, better than nothing. But not going to write home about that.
So oh jeez, what else have we got? Measure all our statistics Gating Ah, you can do the measurements. Okay, the measurements can be based on either the screen or the full record. Nice. Okay, excellent cuz sometimes you only want to see what's on the screen or you want to use the full memory depth.
so X and or between the cursors. Check it out. There we go. so you can only you know if you I only want to measure the frequency between those cursors.
Ignore any other crap outside of that very nice gating function for the measurements. Beauty I Like that. okay display all see. why? does it? If it's only got one option here? Why? Why can't you just cycle through the options down here I Don't understand that I Don't like this sort of Jewel operation I Rather have everything either down here or on the side like that, you know I I Keep getting as a first time user I Keep getting mixed up.
Well, where are things going to appear? Are they going to? I Expect I Keep expecting them to appear on this. uh, vertical soft menu when they're actually popping up on the horizontal soft menu and people have probably been screaming at me. Um, oh, look, it's on the screen. it's on the screen.
You can't see it cuz I'm looking bloody here for some reason. So Auto High Low histogram best for pulses High Low Max All right. nice so we can capture the high and low values. I'm guessing statistics on.
we need to add a measurement. add a measurement. What do we got? Okay, let's look at some of our measurement capability. I Think it says it's got like 34 measurements or something in the blurb for this thing.
It's supposed to have a lot. So how do you scroll? Where are the more measurements we got? Peak to Peak we got time for Ah, Okay, so these are our subcat ories. Are they there? we go? All right now. we got a sub menu.
Look at that. All right. I Don't mind the operation of that, it's just not. It's a bit nonobvious at first, but once it does pop up I Actually rather like that.
check it out. So PE to Peak Max Minan Amplitude high, low geez, No shortage. Um, overshoot, pre-shoot All sorts of stuff. No shortage of measurement capability in this thing. That's really quite nice. So let's actually how do you select it? So you got to press select? Okay, our frequency's popped up. Let's say we want our period as well. Okay, so they're all appearing in this window down here so you lose a bit of your uh screen down there.
I Wonder if you turn the menu off? No. see. Oh, there we go. Turned the menu off great.
I Was hoping that would happen I Was hoping to expect to see those measurements that were on the display window before to jump outside the display window. Excellent. I Like that. I Really like it.
Transparent menus up here. Not bad at all all. So I think the measurement capability in this thing looks quite impressive. Source: and you can, uh, take the measurements from the math as well.
Very handy. Okay, so you can get two different. You set up two different sources for your measurements and then you can get statistics. We should be able to get our statistics.
There we go. And if we turn our menus off, ah, our statistics vanish. Jeez, Thanks for that. There we go.
You have to turn that on to see your statistics. There mean min max standard deviation. Okay, excellent. So the measurement capability on this thing pretty good.
One thing I don't particularly like is that the waveform intensity. Um, you can change it between color and gray scale. Look at color. Color looks awful.
That looks like cartoon gimmicky like. sort of. you know. Um, you know, 8bit 1980s color or something like that.
That looks pretty awful. Waveform, gray scale, and color intensity. Okay, so waveform intensity. it doesn't have its own dedicated control on the front panel.
I Don't like that. I Like being able to have a dedicated Um intensity knob. Okay, so you can change your graticule. There it is.
I'm assuming you can change your graticule between dots and lines. Yeah, no. Dot and Vector mode for the waveforms. So there we go.
We have dot mode. Oh, we had we had dot mode. We're in dot mode, but that ain't dot mode. Look? Well, I Expected to see dots there.
Why? Why aren't I Getting my dots? Give me a break. Anyway, we can change our persistence time to 16 milliseconds. There we go. We can 8 seconds.
Whoa. Okay, so we can set almost infinite persistance. Oh no. there We go.
Okay, what do we got here off? I Assume that's going to affect the waveform update rate as well, but because we don't have a trigger out uh, option on this thing, we can't measure the waveform update rate. so H I'm I'm not really digging the user interface on this thing. It's a bit quirky. I Guess you'd get used to it I Mean it's not I don't think it's the worst I've seen.
It's certainly not Lacroy bad. Um, your old school Lacroy bad that's for sure. But look at that dots and vectors like okay I can see some dots in there I'm not sure if you can see. yeah, you can probably see that on. HD Let me change the horizontal POS Oh that horizontal position's a bit jumpy, bit bit jumpy. but yeah, you can see the dots in there. so we are in dot mode, but then look at that. It seems to have changed over to vectors when we go up.
when we increase our horizontal I that's that's that's crazy. So look, there's dots there. you can see them. I expect when I expand that horizontal time base out we at 5 NS per division, we can still see the dots.
but then it goes to vectors. Why If I Want dot mode if I put on dot mode I Want my bloody dots? Damn it. Anyway I Don't like that the curses are the same color as one of the waveforms. They probably could have made the curses a different color there.
And by the way, the uh fan noise on this thing. Little bit loud, little bit distracting. It's a certainly loud and it's sort of got that sort of, you know, noisy, ballbearing kind of uh sound to it. Certainly louder than the Ryol 2000 and louder than the Agent the Agilant one's.
reasonably loud, but it's a nice, smoother, more calming sound. I'm not sure if I can get it. Hang on, let's trying. I'm not sure if it changes with temperature or not, but it's you know it's not.
I wouldn't say it's loud, but it's not quiet that's for sure. so little bit distracting. It's very quiet here today. There's no, it's on the weekend here.
Um, so there's no other off noise from other offices. no uh, noise from the aircons next door and I can certainly hear that being sort of like the only in instrument on here at the moment. So little bit distracting. And this is rather nice.
You get a certificate of traceable calibration. Good enough. Unfortunately, no values, but it does tell you what. uh, they Ed a fluke 852a to uh, calibrate it.
It was uh, cow day. but anyway, it would have been nice if they gave you the Uh values. All right, let's do a quick comparison with an amplitude modulated sine wave. I've got a 1 mahz uh carrier modulated with a 1 khz signal 120% modulation and as we've seen in a previous video, this is against its direct competitor Ryo Uh DS 2000 series and you can see the beautiful intensity graduated display.
Look at that on very analog like I've showed this in a previous video. You can see the intensity marks in there Beautiful, beautiful analog like persistence display on the Ry 2000 and as I mentioned before, just having that waveform intensity knob there. just just very nice. It makes you feel like using an analog scope whereas look I've got them at the exact same time base.
uh, 200 micros per division. Yep, there we go. 200 microc per division. You notice that the here's the where the wide screen on the Ryo is in: Advantage You can see, um, a bit more information than you can on the 43, but I you know I You know it's neither here nor there really. but look at that. I mean that is not. That is not a great analog like display. I Mean you know this thing's advertised 880,000 waveform updates per second? It's got there.
It is blasted over the front panel VP Visual Persistence Oscilloscope and well look. it's just look at all the the vertical lines in there. It's it's just nothing like an analog scope or like the Ryo scope. not even close.
Holy crap folks, look at this. I just froze it right? So I went from run mode to stop mode and watch this. I'm going to zoom in on the time base. Look at that.
What the hell is that looks like some hairy monster from the Black Lagoon Are you kidding me? What the hell is going on in there? Look at that. That's you. Know there's nothing that waveform that. that's not the look it, look.
It looks perfect there. But then look. it's like it's got some sampling issue or something. I Don't let's let's try that on the Rle I Haven't tried it yet.
Let's stop the Ryo There we go. We're stopped. We're zoomed in. Look at that Beautiful.
Not a problem, what whatsoever. There's nothing wrong with that input waveform. It's coming from my Ryar function gen. Maybe it's detected that there's a Rior function generator hooked up and oh no.
look at that and and and it just vanishes when you go to there. What the hell? What is that? What is going on there? Let me let me try that again. At a lower vertical scale, let's like go down a couple uh, sorry, higher vertical right? There's our okay, there's our waveform, much lower vertical and let's stop it. No, no, we're not getting anything there.
so let's go up a range. Let's run it again. At 200 micros per division, make sure we're doing it exactly the same. Yeah, look, look.
that one there has it. That one there has it. What the hell kind of artifact is that you tell me I've never seen anything like that before. I'm pretty darn sure it's not the input signal that's not my function generator doing that.
Now it's on this part of the waveform over here. Huh? Is this like a Pebcak error? And I'm not just using this thing right? Let's go to. let's press the default. Okay, I just press the default button on the front panel.
Okay, oh, let's let's do. Let's see what happens when when I do auto set. Let's just Auto Set processing. Hang on.
I Know this is the cheaters button here. All the relays going clickity clack clickity clack click clack. It's taking his bloody time. Thank you very much there.
Oh okay, yeah, all right. it's uh, zoomed right in. Okay, let's go back to 200. I By the way, that's not a fire I wouldn't expect any auto set I I think I've tried that on the other Scopes and they don't get that auto set either. So I don't uh I Don't blame that at all. Let's try and have a look at that uh VP capability again. in this case, uh, using the built-in demo signal down in here and building the default FM modulation signal on demo output to there so you know, can't complain that we're uh, you know, not using the scope's own built in functionality. Let's compare it to the Ryo here: I can't really notice in same time base here by the way.
uh. waveform um uh, intensity is both at maximum here and I you know I really can't sort of pick the difference on those to really? they're both pretty good. The waveform update. Rate it, it all looks right.
pretty equivalent there. I'd say no problems at all, but let's turn the intensity down on this one. once again. it's got that dedicated knob you can tell that they're real designers of Scopes Theyve really thought about it and you can see that the ones that stay on screen longer.
It's got that analog like functionality are really bright. like that. You see the same thing on the agilant and the tech uh Scopes the Scopes that have this real uh persistence technology. but this VP it doesn't seem to do anything.
Here's the waveform intensity: I Got to go into a menu to get it, but if I turn it down, it's just like the same thing on like a cheap 1,000 series. Ryo There's no intensity grading there at all. it it seems to be a bit of a con. so I You know it.
It thumbs down to the visual persistence oscilloscope technology. I Just don't get it. It's just like any you know, uh, single um, intensity thing just like in any regular scope. I Mean sure, like any low-end you know, $300 scope like the Royo 1000 for example.
So it's nothing like the you see it look really nice and bright that analog like functionality that we saw with the Am modulation and you can turn on this wanky color thing. In fact, it's uh oh. Now it's all blue, right? because we've got that intensity there. and if we actually turn the waveform intensity up, look, we can get all this wanky multicolor stuff.
But you know. I I Don't like it. Like how are you supposed to know which color is what? It's just ridiculous. It looks gimmicky.
I Don't like it. Proper analog like functionality. That's what you need, so it might be useful kind of. but it's just not designed for proper analog to simulate a proper analog scope.
I Just don't like it I I Call that one a fail. One thing which I think is a little bit of a user interface fail the trigger point. Here There we go. I Can adjust the trigger point, but it appears on this side I Much rather have it on this side here because when you pop up the menu like that bang, your trigger level has disappeared.
Should be on this side over here. But granted, the Ryol scope does exactly the same thing. So once again, when we change the intensity on this thing here, look, all we're doing is is just changing the color of that waveform. It's just. it's just stupid. It really is. Give me the gray scale and when you do that, it's just going right down in intensity. Nothing like that at all.
So I'm actually very disappointed in that V technology. and you know, I was hoping that 880,000 waveform updates per second year. I'm sure it does it on certain, uh, time basis, but I expected that intensity graded display and it's just it's just not there. So I haven't been able to reproduce this uh, glitching problem that I was seeing before.
So um, by pressing the default button on the front panel here, um, that it it seems to have fixed it. So I don't know what what the deal is with that uh, glitchy thing we were seeing before I Got no idea, but you saw it. It was definitely there. so it's a worry now.
One thing that's lacking on the screen here. It's got date and time. Sure, but what's missing? It's got the logo. Not a problem, but it doesn't tell you the current sample rate or the current memory depth being used like you get on the Agilant and the Riyo scope.
And that's really handy to know to make sure that you're using your scope properly, but this one just does not have it. Check that out. Check out that little look. There's sort of like a a single Vector going in there joining those two up there.
I'm not sure what's going on there. that's uh, that's really quite strange. See look see. The rendering of the waveform seems to be different at those two different times basis.
Look, it's not there at all, right? Absolutely perfect except for lack of visual. uh you know, analog like display. but look at that. then they've got this Gap in there with that single Vector It's just not.
You know the the the accuracy of that waveform is just not there and I'm not sure what on Earth is causing that at the very least. it is uh, consistent between Zoom uh mode and uh, regular full screen mode like that. So yeah, your guess is as good as mine and it seems like the only way to see your sample rate is by calling up the acquire menu here and having this ridiculously dim grayed out signal here. Yeah, you can't actually select it, but it does actually update there 2 gig samples per second.
There it is and we're at 10 micros seconds per division. So obviously if we go right down to 1 NC per division right where? uh, it looks like 100 Gig samples per second and it's switched into equivalent time sampling mode cuz obviously it's only got a gig. a uh 2 gig sample per second converter there We Okay, right? So it's not operating real time so that's 2 gig samples. There it is.
So how what does it? 50 microc seconds? There we go. it goes down to 50 micros seconds per division. That's with the cord length Auto and short. Let's it looks like it's automatically defaulted to the short.
Yeah, it's automatically defaulted to short there. So eh, let's see if it halves, Let's put it back to Auto. Let's see if it halves when I turn on Channel 2 and turn it back. Yeah, there we go. It's hared. but like the Agilant, it does not. Harve when I turned on Channel 3, So I've actually got Channel Three turned on there. and uh, there you go.
If I turn on, turn on Channel two, you watch it'll There we go. It's hared. but Channel 3. So there's looks like there's one device internally.
there's one device that handles both Channel 1 and Channel two, then a second, uh, duplicated device to handle Channel 3 and Channel 4. and The Help menu on this thing. very 1980s vintage. uh, sort of.
you know. Doss sort of text interface kind of stuff. So let's go down to AC Choire down there. Look at that.
I mean you know, really old school. but hey, it's there now. Check this out right? I'm in Vector mode at the moment if I turn dot mode on. Okay, we got some.
You know there's some Alias stuff happening all right. But let's press stop now. So let's stop the waveform and expect it to capture the proper waveform and display it. but it doesn't look.
it's still. You can sort of still Alias that between Dot and Vector on the stored waveform. So when you zoom in, look here it is. It's coming in right and then when you zoom in, you can start to see the waveform.
that's just I. Have no idea why it's doing that. Let's try the same thing on the Ryo here. Okay, let's go into display.
We're in vectors at the moment. Let's change to dots. Oky, doie, it's a bit better. but then let's stop that.
And there you go. See, it doesn't do well. It doesn't do it at lower time Bas or faster time bases like that so you know it's all. It's kind of the same, but it's like the Instc one is far, far worse.
So there's something just to do with the display algorithm that's displaying dots in there. I Mean there's quite a few horizontal time bases there settings where you know it doesn't give you a good display. Now let's actually, um, try the same thing on the Ryo here here. It is okay.
we're running. we're in vectors. Let's go to Dots Here There we go. Okay, let's freeze that.
Okay, we're still getting that kind of display, which appears much better than the Instc one, But then, if we change our horizontal time base, look at that. It instantly comes back to displaying your proper waveform as soon as you change it so that it just seems to render the dot in in dot mode. The display algorithm, whatever they're using, seems much better on the Ryol scope. Well, enough around.
With that, let's go into the logic analyzer mode. What Please use: Look at this: Please use the GTL 816 La card to enable the option. I've got the card plugged in. Okay, what I did is I Uh, plugged in the modules again? um I actually hot swapped them I was a bit naughty and now it's going. look CLA module calibration will take 3 minutes to run so I don't know and then we get in all these waveforms on the screen so it's it's calibrating something. so maybe it's now detected it and it's maybe the first time it's booted and I don't know. All right, it's finished and I turned on the option mode here and now it's got function Gen One. So swapping those modules.
um, it obviously tells me that to get the dual Channel function Gen, you actually need to buy two function generator modules at 245 bucks a pop and then you can't have the logic analyzer at the same time. That's what it seems to be. I'm going to have to read the manual on that. but there you go and all you get is your basic s square triangle.
Barely worth it. Do of course Pebcak. Stupid me. I figured out why the logic analyzer functions not there.
It's because you need to actually plug in the probe. Do there it is. Logic Analyzer sorry. It does actually work just fine.
So if we turn down our logic analyzer there, there we go. we got something. bus parallel you AR I Squ Cspi by By the way, um, you don't. It seems like you don't have to pay for the um various decoding of these things.
You buy your logic analyz module, you get your U your I Squ C, your SPI and your parallel. Fantastic. So hex binary event table. It's got an event table.
Neat! I Won't do this here. Um, you know it needs a full review for me to um, play around with the thing. but you can Define your inputs. presumably you can label them on clock.
Edge So that's a trigger number of bits. There we go. select bit. then you got to select.
Why can't you push it? Give me a pushable button for goodness sake. your input thresholds. This is good. You can actually looks like you can Define individual threshold voltages.
So this is a proper log analyzer, folks? Yep, look at that. Does it go negative? soon? You can, uh, set the threshold voltage. if you can't see that, let's zoom in. Jeez.
I Really have to turn this a zillion times? It's got no um, yep, goes negative it. You know the adjustment just has no ability to um to set the velocity mode to know that you're turning it many times in. just go bigger jumps so that's you know that's a really annoying oversight. I think I Not sure if it's the same on other uh menus I Can't say I've actually noticed, um that it does that velocity uh type encoding but anyway, that's uh, really quite good.
You can, um, and it looks like you can set presets, but you can set your Uh individual threshold voltages for each. Channel Very nice. One of the things with the Uh logic probe though is that these cables are actually fixed in there molded into it. so you know it's not like they use like a point standard1 in header or anything like that.
So if you're breaking cables, do you have to buy a whole new Uh pod and assembly and system now? I've got it set up that it's uh, updating the analog waveform at the same time it's displaying eight digital tracers. I Got no digital signals going in here and it's got cursors on there and it's got, um, the Uh DVM was there before, but it seems to have vanished now and well, it's you know it. It does seem to be working, um, reasonably quick. It's updating the analog waveform in the background. it's it. Did slow down a bit, but it's still reasonably uh, responsive with the 16 channels. But check this out. I Press the bus button right.
You'd expect to press that twice just to get rid of all your digital signals. I Can't It's like how do I get rid of how do I turn off my digital signals to get back to my analog I Don't know Bus display edit labels Define Inputs bus parallel I Go No idea if we go into option here then yeah we can like D5 to d0 on off If you press that like turn on, turn off. It looks like you've got to go in and oh no there we go. display on off.
There we go. Turn on, Turn off. There we go. Finally got rid of the bastards.
Ah man, why can't the bus button over here do that? I don't understand. So it looks like you got the bus button here which can turn off the bus display there. Okay, no worries. All right, got it now and then you've got it.
So if you want to turn off your digital signals, they're separate to your bus. So I guess that's a feature. You can still have your bus down here happening without having to get all of your uh uh display happening. How do you move the bus down Like let's say, we don't want it there.
Let's say we want it down the bottom so it doesn't overlay our waveform. I Don't know, it's not obvious. This is not very intuitive folks. Now if we have a look here, it actually has, um, supposedly reasonably powerful uh search capabilities.
And if you go to turn on search here and you can turn search on or off and search type oh a it's bit slow. unbelievable what's going on here and uh, and you think okay, it's only got Edge there right? but no, you press that and you actually oh look, it's slowing down. it was faster than this before. there's something going on here.
anyway. you can select up Pulse width. you can search on pulse width, run excellent rise, four time logic or uh, bus. That's not too bad at all.
Rut is a nice feature to have in there so it's got you know, an okay search capability I guess. haven't actually tried it yet though. Yeah, there's something happening here. it's Look you see those markers up there bang.
It looks like it's it's doing. Looks like it's slowed down because maybe I have got search on and yeah, let's turn search off. There we go. So that's real time.
No, it's still see how it freezes. it freezes for a second so there's something still processing in the background and I'm not sure what unbelievable look if I hit like the default button over here here. I I bet it'll fix this thing you watch if I hit default or auto set or something. Yeah, there we go. Yeah, we, yeah, we're back. We're back from the future. All right there we go. So no, no, is there oh know, no, that's all right.
Yeah, see, we're we're back now. But it was sort of like jerky before it had gotten it itself. It's got it. had its ni is in a knot or something and by the way, there's one notable Uh emission with this scope.
it does not have a high res mode to get greater effective resolution on your front end. I.E do the Box Car averaging um over time, so that's a bit of a disappointment on a modern scope like this. Aha, there we go. I Got the Uh statistics if you turn on all statistics there and uh, well, it was there anyway.
turned it on down here and it popped up blah blah. we can uh choose Channel 2 Etc it's off. but let's go into Channel One for example and there's all the stats. We can get them all at once.
nice. And as far as Uh triggering goes on, the main Uh menu, here, the main trigger menu. um, we've got the basic Edge delay, pulse width, video mode, and others. we can get our run, pulse, rise, and fall, timeout bus logic.
it's all there. so trigger in F Fairly comprehensive, so once again, it's still like freezing every couple of seconds. I Can't figure out why it's actually doing that? I've got no idea There we go. boom and then it freezes for a second.
I I'm sure it wasn't doing that at the start of the video and that really shows you dramatically that it's just suddenly stopping there Like you know that that that triggers just all over the shop of course. but uh I don't know. Not getting good confidence with this thing. One thing I do like is that it does seem to have an internal drive already without having to have set this thing up.
I Just press the hard copy button and bang it. instantly saves I presume the entire screen to a bitmap file nice and it's also got a segmented mode. If you go into the acquire Me menu down here, then you can get go into segments and you can switch that on or off. I haven't actually tried to uh, set it up to do anything uh, mean meaningful yet? but we can actually uh so if you got like bursts of signals like that, you don't waste all your me.
You don't waste all your sample memory. Of course you can capture all those uh uh bursts um separately and display them and it looks fairly flexible. Um, but I'm going to have to get a uh a real world uh test with this and you can select the segments. You can analyze the segments.
don't know what that is? Haven't read the manual? You can save them and go back so you know you set the number of segments that you want to do and that utilizes the Uh 2meg sample memory in this thing. So I'm um, sure it works. I just have to uh set up a decent use case for it and uh, get it working. It's not something that just works at the push of a button. so I think I'm going to call it quits with this. uh, just unboxing First Impressions Video I think I have to actually go read the bloody manual on this thing because I'm sure I've been I've missed quite a lot and uh, and maybe uh, using you know, doing things uh, wrong or something like that. But anyway First Impressions H I Got to say I'm I'm relatively disappointed I Expected more spit and polish on this thing and it's just not the uh, the VP uh capability. Yeah, it's it's I it's got the hardware to do it I Just think it's implementing it.
you know, incorrectly with all this stupid color display on here I Want the proper intensity graded analog like display please? I mean it's got the hardware to do it I Ah I don't know I think they've just implemented it wrong. Silly. And there's quite a few implementation things on this that I Um, don't particularly like and like no dedicated uh, waveform intensity button. Really annoying.
You know the key feature does. VP You should be able to do that waveform intensity with a dedicated knob. instead. they've got dedicated bus knobs and you know, dedicated test knob which calls up these apps.
I mean what? why? What a waste of a key? crazy I I don't know I'm just ah yeah. I Expected more spit and polish there seem to be I don't know if there were bugs in there I Don't know what those waveform glitches were or those uh, waveform freezing I was probably in some mode that I'm not aware of I don't the the look of it isn't all that professional. uh I don't think I think they need to get a proper uh, you know, industrial designer in to make it look a bit more professional. Looks a bit cheapy and toy like, but the quality, you know the physical quality of it is actually.
uh, not too bad at all. But and it's quite reasonably priced as well. But disappointed with the options I mean you've only got two option slots on the back? You can't have both signal gens and the logic analyzer for example. or uh, you can or you can only have one signal gen and a lan VGA card for example.
or you know, a Gpib card or something like that. So and the function gens are very limited I mean it certainly wouldn't Uh, you know, they're barely worth the 245. um Buck But you know, as I've said, waveform generators inside Scopes that were started with the Agilant 2000 series really handy things so you know maybe it is, uh, worth getting. Just you know, your basic S square triangle stuff would have been nice if it had some modulation capability.
For example, um, you know I don't expect like external modulation, but you know, certainly some sort of internal modulation would have been nice. The uh logic analyzer I don't know. Haven't really tried it yet. 500 bucks for your eight channel it's you know it's okayish priced for these um MSO type things. but yeah I don't know I expected a bit more spit and polish, no pushable buttons stuff like that. So I don't know I'm going to I think I'm going to need, um, more time to warm up to this thing I'm sure it is capable of, uh, quite decent, uh, performance. but um, yeah I think it just needs a bit more spit and polish like I didn't immediately take it out and go wow wow, wow, You know there none of that wow factor like oh, they've done this, uh, right and all that sort of stuff I kept finding things that I go, oh, why did they do that? You know things like being able to adjust the waveform frequency, you got to dick around, um, you know, moving the cursor across and key velocity, and just little small things like that. But anyway, this hasn't been a review, this is just a first impression straight out of the box.
So you know I've probably got a few things wrong and I'm probably giving it an overly hard time. perhaps I you know I don't I don't entirely? uh, don't entirely know. So yeah, I'll um, give it some time. Let me, uh, use the thing and really I need to do set up proper dedicated um, uh tests which show off a particular capability and then put it side by side with other Scopes and you know, see how it actually uh performs.
but yeah otherwise H yeah I don't know. verdict at the moment? Well, the verdict is still out I think I need to use this thing more. Wasn't overly impressed though. First Impressions but uh, that doesn't mean that it's not a decent scope.
It's certainly, um, good to have another option on the market, especially from a company like GW Inu You know, do make uh, reasonably good quality bits of Kit So I have to do a tear down of this and I'm sure the internal uh quality I'd be very, uh, surprised if it's not, uh, the design and build quality inside isn't uh, quite good. just I think probably let down by some user interface functionality and stuff like that. it just I You know it's not like an analog you know scope like you get say on the Ryo one with a nice analog persistence display and all that sort of stuff. Very disappointed in that I really expected that.
but anyway I'll get back to you on it. ver verdict is still out folks he Anyway, what's that Being over a bloody hour or something like that? Sorry catch you next time.
looks don't matter, what matters is what is under the hood!
"That's not a knife" 😀
I think its a great scope for the price. The menu navigation is a bit clunky, but once you have used it for a bit, you get used to the quirks. Scope has loads of functionality.
GW-Instek last unit they ship him?
and it goes without saying that I salute him for keeping it honest and not putting his ass up for sale, as a scope consumer-influencer.
Keep that backbone in check.
Each oscilloscope has its properties, trigger
is usually not optimal, eg with AM / FM modulation.
My DIY Ex. Trigger has 24 steps and triggers
each setting very good.
Your comments about Electronic measuring device
I think it's very good, it's a good factor for me.
Many thanks from Walter from ULM (Germany)!
Hi EVVblog!
I have the GDS-3504 GwInstek for about 2 weeks
4 x 500 MHz Scope about 4000 €.
A great scope with a lot of special equipment of the lot
The Spectrum Analyzer RIGOL GDS 3404 with Tracing Generator 9 Khz
1500 Mhz I guess that's a good assemple
for the hobby area.
Best regards from Walter from ULM (Germany)
Dave, what you mean 'industrial design'? I'm working offshore, got tons industrial gear onboard and it have one common feature: strudy design, simple shapes. Industrial design means: reliable, simple. Not some fancy curvy design similar to consumer electronics. Remember HP scopes in mid '90? Maybe they're ugly but the oscilloscopes are mainly used for measurements not as good looking toy. Any review should put the comments on the look aside as every used likes sth else. One might want to have all the knobs to be stainless steel, the other one wants colorful flowers printed around the LCD. I'm not saying which one Instek vs Rigol is better but i'd like to see more balance in review. You can't create the feeling someone has paid you to push Rigol in front on other brands… This is the feeling many have right now.
first impression: "it's a bit ugly"
hahaaha made my day
Why waste a key? its one rugged scope. that's all best than TEKTRONICS CRAP
Hello,
But…
again, your words""what the hell is going on etc., etc ".
Perhaps this is regular in New Sealand, I do not hope so.
I want you to remember the stuff your are speaking of is pure material. Then hell or Heaven does not have any certain goal. As will be all the animals witch have no sinners.
i.e. you are speaking about your soul which can be (hopenely not) lost (as mine) in the end.
Christ is born for sinners
.
Peace on earth, and mercy mild,
God and sinners reconciled."
Merry Christmas

Youre voice, It's like a dunkey's rattle, getting impressed when an amorphe stage is getting blue or pink.
Rebatched under ISO-Tech on RS Components these days…
Great review. User interface engineering seems to be largely lost on the Taiwanese and Chinese. Let's say you were running the function generator into an amplifier and set the level and frequency while using the sine wave generator. You choose square wave and the frequency and amplitude change to something that could easily blow up your amplifier. FAIL! And I agree. If Fisher Price or Mattel toys made an Oscilloscope for kids it might look something like this one. I can live with poor aesthetics but the user interface, slow updates, lag, aliasing, etc, all adds up to a total fail. Buy a Keysight (Agilent).
How the hell do you update the firmware on the gds-2000E scopes??
The instrument ask for a *.UPG file, but from the download page on GWinstek website the firmware comes in a RAR archive containing 3x *.ROM files inside…
When I saw those buttons under the screen they remember me the OWON oscilloscope, with all the pop-ups menus and this one has the same silly system! The bottom line here is the user interface. For some reason Chinese manufacturers have some fails in this domain. Even Rigol did a mistake with the 4 buttons on the top right bevel, some people complain that press those buttons involuntary, because naturally you pose your hand on the oscilloscope to press other buttons, so the interface should be completely flat, no bevels! Some "extras" that lokk nice many times are annoying, like in this scope the wave memory frequency in the frequency generator. Other thing are the push buttons, they are very handy, so if even the most cheap scopes have them there is no excuse to this expensive scope doesn't! Ergonomic fail! By the way, screens should be 16:9, anything different is obsolete!
first time uing dso scope weird even though you watch, read everything you get you hands on. DSO dont trust what i see yet. have analog scope right next to it in case something look odd or until you get used to using "d" scopes.. always have analog back up!
Wow, I guess if you want to learn about this scope, you've got to go through Dave's learning curve! I think this is an insult to users. Go learn the darn thing, THEN do your review! FAIL!
I've seen the display freezing you talk about at 1 hour into the video on an old THS720A Tek hand held DSO I have at work. I haven't been able to work out why it does it either. Resetting the scope or using auto ranging clears the problem but comes back when I change the settings myself. I wouldn't mind finding out why it happens because it makes using the scope annoying.
Well, I found this review "intriguing." I've had some background on such usability issues (Well, about three decades) and while I've never played with this unit, from this review from you Dave, it seems like many issues arose and they're due to engineers who either didn't test it fully, or as a lot of eng's do, they assume "Well, the user will just figure it out." That ain't good. And there seems to be a lot of fundamental problems with making this 'scope work properly. My guess (And it's just a guess) is the FW for this needs a lot of "tweaking." (From your review I'd say it needs an "overhaul," however.) Anyone who buys a 'scope like this is experienced enough to put it to use, but from what all you showed us was that it's just plain HARD to use. I understand your confusion on using this 'scope. Personally, I really don't like poor UI's. And this thing seems to just REEK of "bad design." I'm not sure but I think the HW is up to task, but the FW just falls way short. It'd be interesting to see if they fixed the issues (And that includes the industrial design) at some point. Again, I'm not familiar with this product and I happen to be in the market for this — although I'm sure they "evolved" their products in the years, but if this is an example of how they deliver products, I dunno. I think I'd have to scratch this company off my "list."
Thanks for the review. You, again, did a wonderful job. <smile>
Great example of Daves quality and absolute professionalism here. The guys at GW Instek would give a great deal to have had his insight at design stage. We are lucky to have him.
"Old school LeCroy bad?" .. i'm a huge fan of the old 9400 series. What did you not like about them?
