Hi I thought I'd do a quick video just updating the firmware on my Ryo DS 2000 scope. This is the DS 2202, the 200 MHz uh model and uh, we've got brand new firmware courtesy of John South at Imona. Thanks! John Apparently fixes some bugs and issues as well as a pretty major oversight. Not a huge deal, but bit of an oversight on the they swapped the X and Y uh channels on the XY mode.

Um, so channel one is Y and channel 2 is X which is opposite to what the norm is even though they're not actually label down there X and Y but still. eh. Let's um, give it a go so we'll power it on here. And did I get it? No A That's a bit annoying.

it didn't register that first press. got to press it a bit harder than usual and uh, it'll take us time to boot up. Um I'm not using my lapel mic today I uh, it ran, ran out of battery and I don't have a spare one. So I'm actually trying out the automatic uh uh.

Well, I'm using the internal mic on my Canon Hfg10 here and I'm trying out the automatic gain. so I hope this works. Bit of an experiment here I won't know until I uh read it back. So apparently there are two ways to update new firmware on this uh, ryol scope and depends if you've either got the full licenses or the trial licenses cuz apparently when you buy this puppy, it comes pre-installed with the trial licenses for everything like the Seral decoding and uh, all that sort of and the extra big memory and all that sort of stuff.

So um, which is a clever thing on Ryall's part because it sort of sucks you into getting used to having that real big memory in the serial decode. so they're hoping that you'll Pony up and actually buy the uh option for it anyway. So apparently it's different. If you've got got the um full version of the license, you just power it up like this.

you put in the stick, you go into utility and options and you just update the firmware as normal which was what we'll do cuz I'm pretty sure if we go into utility uh, where is it options, utility system is there another menu there options and then installed we can. official version: So yeah, I've got the official version of apparently it says it'll it won't have the if you've only got the trial licenses, it won't say official version. it'll say trial licenses or something like that. These are all the licenses.

by the way, there they all are. They're uh, there. there's run all the trigger stuff, the decodes, and the memory depth. Now unfortunately, you cannot actually upgrade the bandwidth on these things as just a software option.

You've got to do that when you buy it, which is a pretty big oversight. I Think on the part of uh Go I'm not sure why they did that. Maybe they will in the future. I'm not um I'm not entirely sure, but anyway.

um, these are the options available and looks like my one's fully kitted out. so uh, we can update the firmware in that. but apparently if you don't have that, you turn it off. And if you got the trial licenses to update the firmware and keep your trial licenses, apparently, turn on the unit and at the same time, press the help button.

Okay, I'm pressing the help button and apparently something blinks at you or something. I assume I'll keep holding down the help button. So let's and see. single button is lit.

No single button is supposed to be lit up there. No, uh, no. I Got some instructions that that was the case Anyway, doesn't look to be the case. Oh well.

so let's just check out this XY swapped mode thing cuz it's rather hilarious really. We're in YT mode at the moment and there's roll. Of course there's your traditional roll mode and we've got oh XY mode. Let's go in there and let's adjust the um E channel one here, which is usually um, you know, sort of buy sort of uh, deao standard the x axis input so we expect it to move X oops Oops.

it's moving up and down so it is certainly Y And there you go. Channel Two there is X So yep, they've kind of goofed that up. Um, and there's no like, uh, label or anything on there though to tell you maybe it is in the manual I haven't actually looked um in the manual? so uh, but there's nothing. Usually there's like an XY there to tell you which channel is what.

So that's maybe a bit of an oversight on the uh design of the front panel, really. But anyway, let's update the firmware. Got it? Uh, the I'm not sure what version is, so let's go in and check what version I'm pretty sure it's like 1.0 So system system info. There we go we are.

Hardware version: sorry hardware version: that would be like the Fpga version um I would assume so the hardware because you've seen if you looked at the tear down. you've seen the multiple Fpg in here. so they're obviously 1.0 and the F software itself is 00. Z.0 one.

So there you go. That's uh, pretty fresh. Do you trust it? I Don't know. Anyway, let's go let's go into utility: So The instructions are uh USB stick and insert insert USB stick.

There we go. We have inserted y Ah, there you go. It's automatic Al detected the firmware and it's automatically detected that I've got one point uh sorry DSP Okay, so it's only updating the uh DSP I.E the actual firmware itself. That's that uh, black fin uh DSP processor in there.

so it looks like it's not going to update the Fpga at all. Uh, cuz I've only got one file um on the disc there and it's going to update it to 1.0 Well, it's now I've got 01 whereas before it was O So well, maybe no, maybe it skipped that. Maybe it skipped 01 at the start and only said o1 I don't know. Anyway, never.

Uh, confirm update. So how do we confirm it? Okay, let's give it a go. Fingers crossed, it's uploading. anyway.

I'm using the automatic gain on my mic here. so I'm standing like maybe 65 5 6 in away from the mic on the top and I'm not talking even if I start whispering now I can looking at my V meter and my Vu meter is almost like -1 -2 DB it's really up there. then if I talk loudly, it should not. Peak I don't see it actually go into the red.

So I'm talking louder louder louder. and if I walk away from the mic I'm about a meter away now and now I'm about 2 m away, you'll probably hear some Echo because I'm in the lab here of course and uh, I'm at my tear down bench. I'll walk over here close further away, couple of meters, maybe 3 m away at the moment and it should Auto gain my voice. Um, so if this actually works, Um, so it it's it.

Might have a compressor and a limiter as well. It seems to have some sort of limiter to limit any. you know if I speak loudly like that or if I speak softly like this at the same distance, it'll have a compressor and a limiter. Perhaps working in combination or something like that? Um, anyway.

I'll give it a go, let me know how this sounds. Oh no, there we go. No, it is updating the Fpga configuration. go figure.

So we'll see if that uh hardware version is changed. So I'll come back when it's all done all right. It's booted up and look, it's swapped them two is now on. the let's go out here bet that's I I can clearly see that that's uh, changed.

We've got Channel 2 here is Y and channel one is X Oops. Anyway, it's fixed. So let's go into utility and uh, system and system info and what have I got. There you go.

It's still saying hardware version 1.0 So even though it was updating that, um said it was updating the Fpga configuration. Um, it? Well yeah it. uh, still saying 1.0 but the software version is now 01.01 SP 9. There you go.

So that was no problem whatsoever. No issues at all updating the firmware. Pretty darn happy with that. So let's uh, switch it back to Hey There We go.

It's uh, showing some. it wasn't doing that before anyway. Oh, we're on. Well we are on 500 microv volts per division for the second.

Channel There there we go. So yeah, if um, you let's have a look at that actually let's go all the way down cuz some people have asked to see the noise floor on this thing. Well let's let's go out of roll mode shall we? Oh let's go into YT mode again and this is the noise floor cuz one of the big features of this Ryol scope is the 500 microvolts per Division and um it's you know it's very impressive. I mean I I uh had a look at the Tectronics triple 25 analog oscilloscope uh which I've shown in a video or two and it's got 500 microvolts per division.

but I think since that day like you know I don't know any scope in the last like 15 years that's had 500 microvolts per division vertical scale. So oh anyway, that's five Ms because it's set to uh time 10 there. um that's one of the more unfortunate things about the scope is it doesn't have Auto probe uh attenuation detection so you've got to actually go in there and and set that and it's got a it's got quite extensive. Oh the value.

wrong wrong knob can go times a th000 down to uh 0.01 so we'll It's a bit touchy times one so we'll lock that in and we're 500 microvolts per division there and that's the noise we're getting with full bandwidth. Okay, so that's it. Uh, where's the horizontal 10 micros per division? So let's take it right down. Let's go down to 2 NS per division which is the fastest and it looks like we're in dot mode there.

So let me go into maybe display. yeah, dots. There we go. Let's change it to vectors.

There we go. that's better. And and we've got our persistence time. Waveform intensity is only 50% at the moment, so we can turn our waveform intensity all the way up.

or we can turn it all the way back down. That's nice. It'll be nice to get like a real signal on there, like a video signal or something there that we can have a look at. but you know, I I Normally you know as a rule, maybe leave it around 80% or something like that.

I Find that works pretty well. The display brightness here. Um, oh no, that's the no. That's the brightness of the graticule there there.

There we go. there, we go. That's the Grid in the background and you can have different types too. You can just have the crosshairs like that.

In fact, I'll turn the brightness up so you can actually see that. There we go. and uh, or you can have nothing. You can turn off the grid.

So there we go. I Like my traditional grid there a bit low. Probably doesn't show up that great on camera here because of the Bright Lights By the way, this screen is, uh, not the best at looking directly on. Now that's probably directly on.

You can see some glare from The lights there, but if I look at it directly on, it's pretty washed out. It's really designed to be viewed at an angle coming down like that. So the screen. um, yeah.

that's a bit bit of a limitation of the screen on this thing, so it's not the best. Um, but still. anyway. uh.

menu display is infinite where it gets rid of the menu stuff like that. This isn't a review, this is just having a little play around with it here. and uh, so what we're going to do? Yes, we're going to look at the uh noise floor now. when I first got this thing I took it out of the box and the first thing I did of course is check this.

500 microvolts per Division and that's pretty darn acceptable noise. at the full 200 MHz bandwidth, that's only a division or so there. You know it's not. Uh, it's not.

It's not huge at all. Oops, accident. That's another thing. one of the these buttons up here.

they're a little bit annoying because they're up here and often I I'll put my hand like on the scope here when I'm just I don't know talking or thinking about something or doing something and I'm always accidentally hitting these buttons which is really kind of annoying. I Really do like the look of them there, but from a practical aspect point of view that is just like I've I've done it t almost every time I use this scope I've naturally put my hand there on the corner of the scope like that and I'm I'm run, stop, and turn to single shot mode all the time. It's really rather annoying. Ah boy.

Anyway, the first time I got this scope, turned it on I wanted to check out the 500 micr per Division and there was quite an offset. There was a couple of Divisions offset or three divisions or four divisions offset or something was quite large. Um, so the DC offset by fault from the factory out of the box seemed to be really quite large. but then I ran the calibration function which is in here somewhere I won't go through it now cuz it does take some time.

but I ran the uh oh no. Okay, so I W go through it but I ran the self Cal and it got rid of the uh DC offset there and uh, so we'll exit that and as you can see that one's sort of spot on the center and that one's sort of lifted up a little bit from the Center there, but not a not a huge deal. Of course this will vary with temperature and you know time and all sorts of stuff. So if you're really, um, working down at that 500 microvolt per division uh level, you really should run your uh self-c every now and then I think so.

It'd be interesting to test that over temperature actually. um, to sort of cool this thing down. Sort of put it in the thermal chamber. although my thermal chamber is not uh, uh, capable of uh, cooling down.

uh, the scope at when it's operational. But I could cool it down and then maybe power it up and see if that changes I won't do that for this video. Um, but it could be interesting. Anyway, that's uh, 500 microvolts per Division And the screen is quite nice.

by the way. This large wide screen and you'll notice it's got 1, 2, 3, 4, 5, 6, 7. It's got 14 divisions across the screen. You may not see that there.

That's quite unusual, but that's what you get with these wide screen. Um, Scopes they've gone the way of video. You know they've gone 169. Widescreen video.

We're getting widescreen oscilloscopes now. go figure. But that is the noise floor. So that's the noise floor over right down at the lowest value.

and I've got nothing connected to the input and that's down at, you know, 1 millisecond per division. So that's that's pretty darn good. But if we turn our input bandwidth limit on, we've actually got 100 Meg and 20 meg options there. So if we, uh, choose 20 meg, oh, you can see it's instantly dropped.

There you go. You don't even have to accept that figure for it to jump into that mode. So there you go at 100 Meg you can see the difference in the noise floor because of course the noise floor is going to be dependent upon the bandwidth. The higher the bandwidth of Silc scope, the, uh, higher the residual noise.

Floow. That's just the way it works. But there you go, so that's pretty good. If you put on 20 meg bandwidth limit, that noise floor is under a division there with a floating input.

Pretty darn impressive. I Really like it. Now there's another thing that I really find annoying on this scope and that's the status leads on the buttons down there. Check it out right there.

That's there's actually an LED in there. you can see it if I Shadow it Like that, you can see it, but you know it's really washed out to the point where that's not just a cam that's not just an ontick camera there with the light I can barely see that with my eyes. It's just if I turn it off. Boom.

You know it. It really is quite terrible and Channel 2's on there, but you wouldn't know it. it's so dim and a similar sort of thing. You know it's a little bit better on the the Run Stop button there.

the the the Red's all right, but the green is just really washed out and horrible to look at so they really need to I think up, uh, the current on those leads because it's really not acceptable at all. Now one of the really nice features of this scope, which I really love is this waveform. uh, preview this waveform capture and playback feature that they've got here. This big knob over here you that lovely springy sort of knob and they've got a record.

So here it is. They've got a record button there and uh, they've got a play pause button and a stop button and it basically allows you to capture and replay all of your waveforms on the fly. So at the moment, let me demonstrate we're 5 milliseconds per division here. So 5 milliseconds per Division and we're at 100 Meg samples per second and we're capturing seven Meg points of we're going to use seven Meg points of memory there.

Now that seven Meg Point points is important, because this scope has a maximum of well with the extended option that I've got 56 Meg of memory. So why is it only using seven Meg points? Aha, it's doing that because when you turn on the Uh product sorry the waveform replay function over here, it will actually capture 7 Meg lots of the waveform. So you know how Scopes have the waveform update rate. You know, a million waveforms per second? 50.

This one has 50,000 maximum. or you know, a real cheap uh Ryall 1000 series might have 7 800 waveforms per second. This will capture a complete snapshot of those seven Meg points to fill up that 56 Meg point Point memory. So let me demonstrate what I'll do is: I'll tap like I'll just get some 50 HZ here.

Okay, I'll just sort of play around with this. So what I'll do is I'll capture this I'll press record here. and and while it's updating that, instead of losing all that data once it's popped up on the screen, bang, it's vanished and lost. It'll automatically capture that and we can replay it.

So it'll capture about seven or eight complete snapshots of waveform there in the 56 Meg of memory. So let me turn it on. Here we go record and it's recording. You can see it's counting up.

Ah see, it recorded seven snapshots of the seven Mego memory. Now what we can do is use this knob here. We can even use the springy one that it will replay all of those waveforms or the center One Just allows you to scroll through one by one and you can see that it's captured each waveform like that. Brilliant.

And it's captured the seven Meg points. So then we can, uh, Zoom hang on, how do we zoom into it? No, we can't do it with the horizontal. We've got to zoom in with oh no, we've got to use the jewel waveform Do we? No, Ah, no fail. This is the first time I've actually tried to zoom in on the waveform.

I Thought I was being thought I was being smart there. Hang on. There should be a way to zoom in on that sucker. That's Center position.

That's the Dual time base. The dual waveform view. Ah, there we go. It just didn't update.

Okay, is that a firmware? That could be like a firmware issue or something? Is there's something going on there? So if we scroll through, no, it's not. It's not updating. It's not updating this waveform. Look that window's moving over there.

What's going on here? No see. We should be able to see the kink in that waveform. so it's not. Ah, I was getting all excited over this feature and I'm not sure what's going on there that there we go.

It's updated. now. it's updated the screen. so there seems to be a screen update issue here.

It doesn't update when you scroll that along. That's really. that's really rather dodgy. Anyway, I Do like the capability itself because it allows you to let's go out of dual time base.

You just see Van. The waveform has vanished here and it'll come back. It's still in memory. We can still look at it, but it doesn't update.

So there's oh, there's some. There's still firmware issues there. Wow. I Just discovered that there you go.

When you start trying out playing around with stuff like this, this is what you find. a that's I Don't think it's supposed to work like that. That That just is counterintuitive. It it should update the screen.

As you go into dual time base, you hit the center I Love All these buttons are pushable of course and you can go into the Dual time base. it adjusts it. There's the little display window but there's no way for form until I Update that, Give me a break. Anyway, there.

What I wanted to show was that this waveform uh, capture feature I'm not actually sure what it's called. um, that it at it relies upon how many waveforms it captures, relies upon the memory depth and the horizontal time base that you currently got it set to. Now I've got this now set to very fast. It's set to 50 NS per division there and you can see we're only going to capture 700 points and that's will double.

if we turn off channel two there bang we can get 1.4k points. Okay so but let's turn channel two back on so it'll capture both of these channels 700 points it'll capture. Well, let's let's get the calculator out here. What's 56 56 Meg divided by um, 700.

Actually, it'll be 1.4 k points. Will it 1,400 points? It'll capture maybe 40,000 waveforms or something. So let's once again, this is a real Dicky way to test this. I should test it properly, but it'll allow us to do it and you'll I'll turn on the recording function now and you'll see it.

It should count. It should capture like 40,000 waveforms. So let's do it. Boom, There we goes.

It's counting up. 20,000 30,000, 40,000 waveforms 45 50,000 Woo! 60,000 waveforms. Brilliant. There we go.

65,000 waveforms that's recorded. There you go. You probably can't see that. There we go.

You can see it now. So it's recorded 65,000 waveforms. Which now you can see why you need this. uh uh.

Replay ring here. Now you can see like it's scrolling through. Okay, so you can see I'm just sort of touching that ring and and you can sort of go through slowly like I'm counting down maybe three per second there. Or if I move, tweak it a little bit more, hold my tongue at the right angle.

it's doing maybe 20 a second. Or then you can go to 100. you know. Add more springiness in there and you can see in real time what I was touching.

See, You can see the real time of how I was touching that probe and it's great. And if I turn it all the way to Max look at that. it's counting down. 40, 40,000, 35,000 30,000 and it replays all of those waveforms.

That and bang. We've gone down to caption number one. And of course, if you want to scroll through one by one, you can use the center knob there. But there you go.

That's it's. an absolute brilliant Feature: Parameters Over Range: I You get this message for a lot of stuff: Parameters Overrange Crazy. What does that mean? Ridiculous Error Message: Pointless. just scares people.

Jeez. oh no. My parameters have over ranged. Oh, what does that mean? Panic.

Panic Quick. My scope's buggered. Oh hopeless. I Don't know.

Anyway, so it's got a few quirks. this thing, but that is an incredibly powerful waveform capture and replay function. I Really like it. It takes up a hell of a lot of space on the front panel there.

I Would have preferred to have a nice nice big that is the nice big horizontal knob over here. instead the horizontal knobs the same size as the vertical. Eh. Give me the old days when you had a nice big horizontal knob on there and you could you know tweak the thing cuz that's the main thing you're going to use.

Not too keen on that. but anyway I thought I'd show you that way for replay features cuz I'm quite excited about that and you can get that on this $850 scope or whatever. even in Australia that's how much it costs. granted Sun 70 MHz vers.

but jeez, it's pretty impressive and but the standard one doesn't come with the 56 Meg memory like this one. Uh, does it is smaller? but uh, for the first month or so you'll have that trial option. You can play with a really deep memory and that waveform replay feature. Check that out.

that's just screaming through. Absolutely screaming through those waveforms. Look at that 10,000 you can see the Bang Bang all the way up you I was touching that probe and mucking around and that's really neat. and I believe you can also go in and dump that stuff to memory as well if you go into uh, storage.

So I hit the storage button here and you can store what? What do we want to store? We can store a picture. CSV We can store the setups, the wave form, the traces, so the traces that are on the screen, or um, or maybe the waveforms I I assume because there's two different options there I haven't read the manual so don't quote me on this. Um, but one of those would be the full waveform dumps. I'm assuming or maybe the CSV gives you the full waveform dump so you can get you should be able to get all that raw data out.

by the way, different um, picture types, bit map uh, PNG uh, JPEG and Tiff everything's supported really is quite nice I like that. oh, default. no I hit something. Anyway, there you go.

That's a quick, uh, firmware update and play around with the new Ryol 2000 series scope. I'll eventually do a full review on this thing, but what's this video? gone? 20 25 minutes or something? and I just played around with a few features and there's a hell of a lot more in here. Let me I just noticed something. Look at this.

You got to be kidding me. 0.0000 00000000 Pico seconds. Woohoo! Catch you next time.
