Hi, Welcome to another oscilloscope teardown! This one's gonna be rather interesting because this is a really bang per buck. entry level for Channel 50 megahertz scope as a GW in Stick Gds 1000 B series I've got the 1104 B but the 10 54 B is the 50 megahertz version for channels for a street price of 386 dollars. that's currently going for so it's cheaper then Tada. It's direct competitor the RAI Goldie's 1054.

Zed Let's check it out. this won't be a comparison, but I can't help it just a little bit before we do the teardown and it's great to see competition in the market like this. They I think they announced this scope back in June but I think it's only been started shipping I fell in recently although I could be wrong on that. Anyway, we've got our hot little mitts on one and we're gonna tear it down.

but check it out. it is substantially bigger than the Rye goal, but it's the right goal. Actually weighs three kilos. this is 2.7 kilos.

substantially lighter actually. But yeah, look yeah. I mean supposed to have the same size screen, but just sort of optical illusion type thing. This one actually GW in stick actually looks smaller so it's not as effective use of space, but you'll notice that it's got all four separate vertical controls.

Absolutely brilliant. Whereas the Reigle you've got to dick around with just the single channel there to do it, so it's much better. So that's the advantage of having the bigger form factor. You can get the extra vertical controls in there, but the GW in stick does actually look quite wasted.

You could have think Lea Now they could have like made it smaller and sort of compacted everything at, you know, it just seems a bit too big. Whoa. Hey, wait until we see inside to see if they've wasted any space inside, but they could have tried to make it more compact. That's one of the advantages of the RAI goal were 1054 Zed Anyway, and you'll notice that this is like a real off-yellow kind of.

Hopefully it shows up on camera. I Have got my white balance set correctly for the color spectrum our studio lights I'm using here so hopefully this should be fairly accurate color, but it's kind of like thinking the case is white but the panel is kind of this yellowy color I don't really like it, but apart from that I really like the way it's laid out. The vertical controls are excellent yes the knobs are push a ball push to 0 there and also for the trigger level as well we can push that back to zero. You can push the horizontal position back to zero.

Fantastic! The horizontal section. It's got that separate search which of course the RAI goal doesn't have so you know a replay up mode and controlled directly there which the RAI goal doesn't have. very nice and I like how the trigger settings here are totally separate. but just like the RAI goal, you don't get an external trigger But that's not uncommon on a four-channel scope and other little niceties.

A 50-percent trigger level button dedicated that Rygel doesn't have that so you know it's got the same mark force button which is okay, but yeah I really like that. Run, stop. The auto set is not sort of recessed or anything like that, but you know the menus. err, look at the buttons there.

all it all looks very bland and amateurish. So I don't know who the you know the user interface product designer is at GW in Stick but I don't know what they've got going I mean the but this is the look of GW In Stick products. Yes, some people might like it. I personally think it just looks a bit amateur.

That's all in terms of like our product design. It's not shout out well that looks sexy, it just looks I don't know mm-hmm but big clunk and power button. ha that feels like a real power button. Oh don't turn it on.

We want to take it apart. but spec wise it is one gig sample per second. which is unfortunate given the four channels because when you I'm sure it will actually have and then go down or quarter Sony 250 Meg samples per second. which is not enough for the hundred megahertz bandwidth.

Fine for a 50 megahertz bandwidth scope they are considering only pay 386 US dollars for this puppy haha for a four-channel scope. Brilliant! It's got the same out 7 inch color display I think believe it's the same resolution as the Roy go. we might boot it up after the teardown of course and it's got fifty thousand ways to pay for updates per second maximum. which is that better than the Wry goals at thirty thousand waveform updates per second.

It's got one Meg FFT which is fantastic, which will have to have a play with in a separate video which to ride old dozen so that's good for signal analysis stuff. And as I said, it's looks like easier to use. and just like the Rye goal, there's no auto probe detection or anything like that. One of the most unusual things about this though is check it out.

Let's go over the top here. Where's my scope? Where's my scope? Where's my scope? Where's my scope? Where is it? Where is it? Ah, there it is. Geez, this is weird. So yes, it's actually very disconcerning at first when you actually look at this thing.

I Mean that's it's not uncommon on scopes these days. Other Other brands I think IO or duo one do this I can't remember, but it does have a carry handle if there's nothing in it. Obviously they got like the power supply looks like power supply tucked down the bottom here and just one big, possibly just one big mainboard at the back there. but it just it just looks weird I don't know, it doesn't instill confidence in me, but I I know that's not right.

but I don't know, it's just funny and it's made in Taiwan as I believe all GW in stick products are cuz they're a Taiwanese company not made in China it's just different yeh and supposedly 30 watts power maximum I Don't know what a draw it actually draws. In practice, we'll have to compare it with the Rygel and on the back we've got USB device. We've got land, which is a pretty standard on in your entry-level scopes these days. Absolutely incredible.

We've got an open collector I Go no Go output whether or not that can be used to get our update rate ie. it's a trigger output as well I don't know you'd think it expected to say it there and a curious calibration be see. So I presume that's only for factory cow but seems a bit of a waste and the scale knobs have indents on them they feel are quite reasonable. but the position controls and the variable are control up here and the trigger level.

they don't have any index and they feel a bit bit scratchy, bit itchy and scratchy not I don't know what to think about that. whether it's good or bad. Hmm. no you don't have to worry about it toppling over if you press the button, so even if you have pressed them vigorously, it's not going to fall over hopefully.

Oh, all right, you know we say you're on the Eevblog. Don't turn it on, Take it apart. Let's go void that warranty Beauty. Well turns out there is no warranty void if not removed.

Sticker Beauty GW In Sticks Support Hack in I Like it and there's just four screws on it. Let's live. Uh-huh Just a couple of little clips under there. There we go and we're now in like Flynn Wow Now the first thing I noticed was just the general like wasted space.

Where is everything I expected. like one a big board, but we've got it like a board effectively half the size of the case. one just inner face board which is just looks like there's no active circuitry on there, just some terminators going off to the LCD there. But there's one other thing can you spot it that I Just instantly went.

What the look the fan. It's sucking from the outside. Okay, there's a vent on the back and it's blowing out the other side. like what the where the hell and like I thought okay it's you know Sutton's getting hot on the front end.

okay and it's blowing right into the front end. Ken But look at it, look at it. That is the what they done. What were they thinking when he put a fan like that that has to suck in it and then instantly just reflect off the shield in there and then just go out here and what It's not flowing over the power supply at all.

it's not flowing out over any of the you know active circuitry. In fact, I can't even see in the active circuitry. got to be on the underside. Where's our main processor? That's our ADC obviously got our four analog channels.

Got some power supply stuff and well, maybe it's under. Here is the main. Well actually haven't see the traces going off there now. But yes, I think I main processor.

but where does that? FY Even that's the fan at all. Unbelievable. Okay I see what they're doing? Now if you have a look at the case, this is why I Said oh yeah. like the power supplies in here, you notice that here is the inlet grill down here.

It actually has a surround around it so the air comes in through the back. It's blowing out here onto this can and then over here. but it can't go anywhere because they haven't put the any vents in the side here so that's good. So all the air essentially has to be pushed across the power supply and then out this vent on the other side with this lip here effectively.

you know it's not a seal, but it effectively contains the air path going in and then across the power supply. But like it's it's got extra air resistance. Here, you're not getting efficient volume of air movement. you know, volume per hour or whatever you want to calculate it in.

You know it much better. I'll sticking the fan on the side here and then blowing it across, but they've only got a certain depth but they probably could have I Don't know I Still don't like it, but it does show that they do. Did actually think about it and thought about the air path and it's mostly over the power supply. That's pretty much the only thing the fans doing so the rest of the circuitry can't get that hot at all.

because they're effectively is no our airflow for it and the power supply looks fairly average and low-cost doesn't really instill a huge amount of confidence in me, but as I said, that big in power switch feels really solid. Yes, it is a real power switch. Why they've got this extra jumper wire going over here like this? I don't know. Anyway, they've got the requisite common mode choke and filtering and stuff like that on the input and well you know it's possible.

Well, hello sailor, look at the primary input cap. It's a Nippon Chemi-con Beauty I'm surprised. and likewise all the ones on the secondary side here. they're all Nippon chemi-con as well.

Fan-freaking-tastic Well done in such a cheap scope. Unbelievable. So whilst that power supply might look cheap, it's not all in appearances. Looks like they've got quality parts.

They've got a thermistor protection down here. There's no fuse protection in it, but that's good enough. they've got a trans or there by the looks of it and all the requisite stuff. Quality caps Excellent.

Just don't still get the heebie-jeebies about that fan. It's probably not drawing too much power, just a standard point one inch ribbon header they're going over for the main power, but you'll note that up in here on the main board. They do actually have some of the solar mass removed and tin coating on a couple of the traces running up there to presumably are the main processor up here. So just to get a little bit lower impedance and extra current carrying capacity.

And if you're wondering about the earthing on that, I would have done it better coming straight from there. But you know they've done the pin thing. So there's there's a pin on the bottom of that in the Senate goes over to this grounded stud, which then just connects on the bottom and goes down to the main. shows you down there.

it's adequate. Well, this is rather unusual. The main board here is effectively just the analog inputs. The ADC is probably a little bit of triggering.

No, that'd be the pass/fail outputs or something. There's probably some triggering stuff on there. Perhaps maybe on the other side of the board. We'll have a look, but this daughterboard here is actually the processor board.

This is the bar of it and there's a heatsink component on the top because if you have a look down there, the main board is actually cut off like this and goes all the ends cut off right down to the bottom down here. like this. So your pain processors on that board what that like? Why have they done this? Some sort of upgradable capability? They didn't want to change the main analog board. I Don't I Don't really get it.

This one's marked as a four channel. Of course, if they did, the two channels that only populate the two channels down here, you can buy a two channel version, but only in the 70 megahertz version. And speaking of which, the two channel 70 megahertz version is even cheaper. So if you don't need the four channels and you're happy with the large size, you can actually get this for like three hundred and fifty six dollars street price or something for the two channel 70 megahertz version.

But I would highly recommend going for the four channel 50 megahertz version any day of the week. I Can't see any compelling reason to buy the two Channel 70 megahertz version. for you know, 20 bucks cheap or whatever. It is thirty bucks cheaper over the four channel version.

No way. Go for the four channel every time. Now the main board actually uses I've never heard of them. Jimmy Caan the brand caps.

Yeah, they aren't name-brand at all. so maybe, um, that's quite curious because the power supply. maybe they are farm that out which is quite common with companies farm that out to a different like a specific power supply specialist company to do that. And they handled the build materials and they specified a Nippon Chemi-con but you know, when Goodwill did these now they're purchasing, people Just went.

Let's get: Jimmy Caan We can get those this week. Super cheap! I Tell you what. I'm not impressed with how they're holding this board down. They've got a high frequency surface mount in it board to board, interconnect connectors on here going down to the baseball, but they're holding these in with plastic clips.

This seems to be just a freestanding stand off. I Didn't realize that so I shouldn't taken that out, but yet not not impressed with that mounting scheme at all. Come on, screws, hang on. I Don't remember taking that screw out.

What the what's going on? Anyway, they've got a much like little springy shield thing connecting the ground on the main board here down to there. but why don't they just screw up? What if they added that and done away with the screw for I Don't I Don't get it. And the other thing of course is that there's absolutely like no shielding in this. The power supply is not shielded from the outside world, the power supply is not shielded from the main ADC and other stuff.

I Mean they sure the analog front end is I. You know, shielded. That's a given. But apart from that, the power supply.

Yeah, you know it's just flapping in the breeze there, but I suppose it's past FCC and all that. So yeah. but it's a stark contrast to the Rui gol. D is 1054 is said, which is why it's so heavy.

It's just chock-full of shielding and shielding right up to the wazoo. Well, here's the main processor board and it is bizarre. It is so not what I expected under the tiny little heatsink here, which is going to have no airflow of course as I explained before and that's most likely an FPGA I Don't think GW in stick of, you know, spun their own ASIC Although to get you know you're going to get like 50,000 waveform updates per second. It's supposedly on spec, at least it's you know, quite a fast scope.

I've yet to try it out with responsiveness and you know everything else but it. You know it's fairly grunty. so I'm assuming that's like an FPGA and not some sort of applications processor, but it drives the LCD directly. So we've got our sample memory here.

We'll take a closer look at exactly what type of they've got ten mega per channel by the way, like and which is not shared apparently. although I'm yet to confirm that we've got flash memory and just the main processor /fp J but isn't an FPGA I Don't think it can be or just never made like it might be a hybrid one with you know, like a Zinc or something like that with a building Arm Cortex-m processor because look, it's got LC Where's the LCD driver right? This goes directly out I Don't think it's one of those like media processes or you know, shark or anything like that because there's just not enough grunt in it to get 50,000 waveform updates per second usually. so that's you know. Quite grunty.

So I don't know what's under there and unfortunately the heatsink is glued on I don't want to take it off because that could require some force and I'd probably bust the decent likelihood of busting the little fragile BGA's on there and it looks like our main sample memory here. These are one gig bit each, so arranged in 64 megabyte 16 bit. so we're talking. You know, well, there's two of them.

So there's two channels per chip. So we're looking at 128 megabytes per chip Meg samples per chip. So we're looking at 64 Meg samples per channel. No wonder they can do then from the 410 Meg samples per channel on this thing.

So what are they using the extra for? Maybe for the variable intensity, our display and the history mode and stuff like that So more than what they need And those two puppies look like Texas Instruments 12:10 Be there right? USB transceivers and that one there looks like guessing is going to be the Ethernet controller? Yes, it's all on the board. We're not right next to the connector, so it's all going through these high frequency board to board interconnects and going all the way over the board along the yellow brick road over the rainbow. -. Oh really? and that is an Analog devices ADP 50/50 - that's just a power supply job II Wait, hang on.

Hold onto your hats this Wiggles this Wiggles it's off. It's a Zinc I was right there you go. It's a Zinc. Like yeah, that was a good bet because it couldn't just be an FPGA cuz it needed you know applications processor to actually run an OS and everything else.

so you know they're not going to put that in some soft core. So the Zinc is that nice chip. It's got AIDS basically in a Xilinx FPGA Plus, it's got an arm core or maybe two inside weft. Check the part number.

Well, that heatsink was pretty piss-poor wouldn't it? And this puppy is a real beast. It's the Zinc 7000 series. Got an ARM Cortex A9 in there. One gig.

whoa and it's a 2.5 Rd MIPS per megahertz. So incredible processing power. It's got a Neon media processor in whatever that does, but hey, it's I don't know, maybe they're making use of that. It's got vector, floating-point units and ah, more bells and whistles in your pocus ticket.

But of course that's just the ARM Cortex processor arena. It's actually a Xilinx FPGA It's the Art X7 architecture and this one's actually the bottom of the range one. actually. in terms of number of logic elements in there, it's the cheapest one.

It's got thirty five thousand flip-flops has only got twenty eight thousand logic elements, so not a big FPGA, but it's got DSP units, you know, and block Ram and like 30 odd K of block ram or something like that, so you know it's They're doing a decent amount of stuff in there, but that's basically it. That's all there is in it. It's basically an ADC which we'll take a look at, coupled on to a Zinc Cortex process a really fast one with some FPGA fabric and bingo. You've got yourself like a modern 30, you know, waking some software, of course.

lots of software magic, but do that. and basically that's all the hardware required for a modern night. You know, 30 50,000 waveform updates per second variable intensity display scope. It's incredible.

Geez. When I was a boy, this thing would have taken a room full of stuff and does this puppy here. A JTAG programming header or a serial debug console interface not entirely sure, not silk screen labeled. Oh, and absolutely no surprises at all.

for finding a hit height analog to digital converter in here. They're in everything. Is this the chip of choice in these low-end scopes? This is a one gig sample per second single channel converter or a 250 make sample second 4-channel All 500 make samples per second to channel. That's why this thing is going because they've only got one of them for the entire scope.

You know, save cost because these things aren't exactly cheap when you're pinching pennies on a scope like this. so we have to share that between all four channels. So unfortunately, the one gig sample per second does drop down to 250 mix samples per second on when you've got all four channels on. So that's not enough to actually get a recreate a proper recreated signal on a 100 megahertz pan with analog input channel.

But it's OK for the 50 Meg bandwidth model. And if we pop the hood on the front end, here, we go four identical channels. Of course, we're in like Flynn and it looks pretty basic. There's probably some on the back side as well, but I'll We'll have to take the entire board out to get a look, so looks pretty basic.

exactly what you expect from a modern hundred megahertz front end. Unfortunately, we can't get this board out without taking out the whole thing from the front panels. Have to take all the knobs off. There's our membrane for the front.

No workers at all. We're gonna have a the main keypad PCB underneath this, but let's swing this around. The reason why we couldn't get it out is because today those are being seen. Nuts Mongrels.

But there's a screen. there's all our keys, everything else. everything's hunky-dory Our LED backlights and things like that for the buttons or surface mount on there. So that's all hunky-dory What switches of these? We've got 1, 2, 4 C3.

There's no brand on these things by looks of it. 1, 1, 1, 2, C 2. So these are the indented ones and these are the just a regular non indebted ones which feel a bit itchy, scratchy, and certain things have to be in semble din certain ways. The PCB mounting power supply studs on here, for example, stop me actually lifting this board out.

So I've got actually take these screws off and move that before I can physically get this board out. So yeah, just yeah, small things like that. but we're in like Flynn and yep, we've got some some stuff on the back. Anyway, these things here look like 4000 series CMOS 409 4 So 8-bit shift registers, so that's obviously you know how they're getting some control data to each channel.

They're just, you know, saving some liens going over the PCB there and that's around our calibration output. Nothing my Chaplin there at all. We've got a TL o7 for classic and another one of those are 409 fors incuriously. we have an unpopulated part there with a heatsink our pad on the bottom not sure that is that's basically just below the analog to digital converter that's on the flip side.

So I that some sort of clock PL or something perhaps looks kind of something like that maybe. but like why is it not there I don't know. Speaking of which, I did forget next to our ADC there we've got an 1102 Te for a whatever the hell that is I don't think it's a hit height. Not sure if it's a head height one or not diff pair coming out here.

We're 200 own series resistors there. so yeah, it's doing something like that. some clucky thing. you know what? There's not much doing on this front end here.

Of course we're going to have a discrete FET front end perhaps? and oh, we've got ourselves a relay and a trimmer cap. No worries, it's all pretty standard TLO 7th or 4 thank you very much. Of course that's not doing any high frequency stuff, that's just doing some level and bias stuff and pretty much all discrete front end. And likewise, if we flip it over the other side, it's still all discreet.

There's nothing else happening in there. It looks like this could be our main puppy over here and nope, it's not that that's an Analog Devices ad 5207. that's just a digital squirt pot. you know, a squared pot 256 position.

So that's just doing some level adjustment and under digital control. So we got on the front and that's our TLO 7/4 We got ourselves a 4 a 5 3 marks. So I'm analog switch as at Elo Seven One jeez is it looks like is this entirely discrete front end? Hang on. It's just dawned on me that these aren't all identical.

Look at them. This channel here. is that? Yeah, that's our channel. One is identical to Channel Three.

Look, we've got two fourteen pin package Azhar Three fourteen pin package. is there. Or fourteen and sixteen. I Think that yeah, they're sixteen.

That's fourteen. But this one has an Esso eight in here instead of this 16 pin package. and his fourth channel doesn't have either. What? the? Apart from that, all the discrete stuff looks the same.

Okay, so there's all our discrete amp all in there. That's the same. but this stuff here differs. Weird.

and this one here is an additional four. Oh Five three. So I've got two, four, oh, Five threes, or one in these channels. This puppy here is a bit different.

It's at Elo 7 too, so it's a dual Op-amp whereas we've got one TL O7 one on each channel. But why does like channel - here have a T O7 - in it and none of the others do. So that's interesting. All discrete front end.

And where have we seen this before? The Rye Gould Es 1054 Zed I've done a complete reverse engineering video of the front end of the Rye goal. So to be really interesting to do a reverse engineer this one and see if it's the same, but it's basically all discrete transistor. The 405 threes, if memory serves me correctly. exactly the same as what's on the right other.

TLO seven fours and everything like that has got two discrete transistor diff amp output and things like that. So I won't reverse engineer this one, but I'll put the high res that photos up for anyone who wants to have a crack at that. Be interesting to see how equivalent it is to the Rygel. Hmm, so you can really see how GW instead of being clever here in that they can sell and why they can sell this cheaper than the Reigai, which was already super cheap, they've got basically an equivalent discrete transistor analog front end and the ADC is different.

I Don't think the Rogue I'll use the Hittite one, so I'm not sure that you know the price comparison difference there, but take a look at the teardown photos of the Rye goal and you'll see that it's got a lot more horsepower in there than the GW instinct. Like, well, not necessarily horsepower, but there's certainly just a lot more chips to handle it. had more FPGA multiple FPGAs to do it, plus a main application processor. whereas the GW in Stick is doing everything in this tiny little Zinc that's basically the entire processing engine for this thing.

and if you can get away with it well, you know which I'm sure you can. It's a super duper powerful chip then that's a very clever and cost-effective so I'd love to know the actual bomb cost of this compared to the uh. Try going to be very interesting to see, but of course we're never going to get that information that's super duper proprietary. But there you go.

An incredibly simplistic design for a modern you know, for Channel 50ml, hundred megahertz bandwidth, the scope with variable intensity display, and all the bells and whistles? Absolutely incredible. Forgot the bloody heatsink didn't I All right, will it work? Here We go. Yes. Burning.

Taking a while and that fans a bit noisy too. Bloody whiny little thing. No wonder. and we're in like Flynn Well, I'll tell you what.

I'm actually quite impressed with the responsive, basic responsiveness of this thing. It's actually really. it's practically instant. It's better than the R I Go.

It's faster. That Zinc process is really kicking some ass. Oh hello. What's that? Whoo! Whoa.

Now I've got four channels on there. And where it? What? Are we? Where it? Where's our is on a five nanoseconds per divisions. They're almost. yeah.

we are as fast as we can go and we've got some funny business happening on. Channels look two and three. No, just three. Is it Oh sorry, just - oh no.

Look, Look, it's going from like there's little that there's periodic pulses in there. Oh no, that's not a division, but geez, look at that. So in the blue, which is the Serena's second Channel didn't the second Channel have that extra TLO seven two in it? It's like it's different I'm at a hundred millivolts per division I've got nothing plugged in. and why is Channel 2 noisier than the rest? And there's this periodic artifact here.

What the hell? Hundred millivolts? 100 millivolts per division? Check it out. There we go. It's whoa. Look at that that looks like a sine X on X interpolation thing 3 & 4, 3 & 4 don't display that.

but 1 & 2 when you go all the way down. What? Look at that. Wow What's going on? Is this super quick though? I've got to admit that display update is really fast and you can see the difference. when I switch between hundred and two hundred millivolts, you'll be able to hear the relay click, right? So it's absolutely rock-solid flat on a hundred millivolts and switches to two hundred millivolts.

and then we get some extra noise us and then that will decrease as we go up. So that's to be expected. So 100 millivolts is the changeover point, But why will we get in? Why are we getting that? Why are we getting? That's very disconcerting. Okay, so if I go to record length here to the acquirement, you can do a thousand points 10 K points Hundred K points.

It's not gonna make a difference of course, up to 10 Meg points. There is no Auto memory on this thing, so you've got to choose your weapon before you go into battle and that's it's. got peat attack that's got average and of course average. You know should fix all that.

I Like the variable knob. by the way, the variable knob is A is a winner and none of this pushing the variable knob. rubbish. So it accidentally you know you don't get the thing that you want to select it and it's right there.

You can use your thumb so we can go like 32 thank you very much. But even with 32 averages, we're still got that crud on our 100 100 millivolt channel there. What the? Okay, so watch this. I've got a more one a hundred millivolts per division here.

Okay, and we'll we'll run it and you'll see that there's a bit more a bit of a shimmy there on channel 3 and if we stop that and then we actually scale I Know this isn't fair. Ok, it's actually we're working with very few bits now. Ok, so you expect it to expand the noise up, but look at that perfect sine X are next. So it's obviously doing that at the at the display processing point because there's very few samples there.

I Mean we're getting like you know, bugger-all So for you there's our you know, jeez, can you even see how? is there even a dot there? Yeah, there's one dot there, you know? So I was like dude and you know. So we're down with a couple of bits so you know, don't think that's it's it's a display processing artifact. It's not necessarily. I Don't believe it's like a problem with the layout of the PCB and the analog to digital converter.

There's no sort of you know layout issues and noise and things like, like just a tiny bit. But when you magnify it up like this, because this is where we actually sample, do that, right. hundred millivolts. That's what it actually looks like.

and it's just when you bring it in, they're clearly doing. not that there's anything wrong with that. I Guess in fact it. You can argue that it's probably a good thing they're actually doing the processing on them on the magnet.

expanded scale, waveform like that. Interesting. But anyway, my real concern is just these little artifacts. And once again, I Believe that their display artifacts caused by the display engine not necessarily sampling artifacts because we go into dot mode and you probably put a rule across that like this.

like bugger. All right. So it's not a sampling issue. there's something happening with the display there that happens only under 50, not only at faster than 50 nanoseconds per division.

So ten, twenty ten, and five nanoseconds per division. It displays that. So not a showstopper, but just interesting to note: I think G W in stick should take a look at that. And of course, if we switch over to 200 millivolts per division, we expect that noise to actually go up.

Because we're You can hear the relays click, boom, we go in, and then of course, if we stop that and we expand those, then we're Yeah, we're really going to get some artifacts, but there's nothing unusual there because we're actually, you know, expanding that in. But yeah, this isn't sort of the quietest scope. So anyway, I'm not I'm being a bit fussy I'm being a bit funny fusspot here, but let's go down to 50 milliseconds. sorry the 1 millivolt per division.

and that's noise floor that's going to clean. That's because of the high sample rate, the high update rate: I've done a whole video explaining why digital scopes like this are inherently noisy in quote marks like this, but that's fairly I Think that's on with the ROI goal 1 at 1 millivolt anyway, and that'll certainly drop if we turn our 16 averages on. No workers. One thing this doesn't have though, is a high resolution mode, which is quite disappointing.

It's only got your regular average mode doesn't have that Boxcar averaging. You know, a lot of low-end scopes are getting that these days, so it's a bit of shame this one doesn't have it. Why the hell have an app button on it if you're not going to actually have any apps in here? I mean do they have any on their website? But like there's just none? Well, anyway, enough playing around with this thing. I Gotta go edit a teardown video I'd love to play with this some more.

Oh and I almost certainly will. but I hope you enjoyed that teardown. As I said high res teardown photos on TV blog.com If you want to have a go at reverse engineering that front end, see if this it's the same as the Rye goal scope. That'll be really interesting.

It's probably extremely similar topology, if not, you know it may not be exact values and component parts and things like that, but in fact the Op amps were different. This thing used as standard TLO 7 4s and if I remember rightly the right guy used T or V versions or you know, like something like that. Just you know, it's slightly better at SPECT parts, but very interesting. Price point: this thing.

it's less than the Rye goal for a 4 channel scope scope. I Have no idea if it's hackable The firmware like I Don't believe you can get 8. You have to buy it as 100 megahertz unit I Don't believe there's like a software upgrade key to actually do that. You know if we go into utility and you know Pro compensation system you know there's nothing like in terms of you know we can do self cow you know QR Code: Yeah, thank you.

but you know there's nothing in terms of like there's software options for doing that. Firmware Version 1.0 9 for those playing along at home, but this was rather interesting. Like you know, corners have been cut. stuff like that.

Constructions not nearly as good as a Rygaard could have been much smaller. Even with the four channels like this, they could have. You know it. Look, there's a lot of wasted space as you saw a lot of wasted internal volume and like that.

Didn't really like the fan, but I like the Zinc processor an FPGA in there combo in there that's real fantastic it seems on first play, couple of minutes it seems are really responsive. We're gonna have to test it for the claim 50,000 waveform updates per second. There'll be some sweet spot in the time base where that works. but I don't think there's an option to get our trigger output, which is a bit disappointing.

so we may not be able to easily measure that waveform update rate, but the hardware is, you know possible, especially for the price point. So I'll give it that. But yeah, it's just a shame about that. It's not maybe a little bit smaller or something like that.

But anyway, if you like the teardown, please give it a big thumbs up. And if you've got any comments, leave them down below. I Always read all the comments. Leave me even Eevblog com.

There'll be huge nerd fight over on the forum about all this I'm sure. but anyway, catch you next time you.
