Hi in the previous video which I'll link in down below and unboxing and first impressions of this oh one. XPS 3200 to a 14 bit oscilloscope. Now listen, a bit of an unusual beast because it's got a 14 bit high resolution inverter which is what what a look at. In fact it's got a 14 bit, 12 bit and 8 bit converter in there which take a look arbitrary waveform generator.

It is not a mixed signal scope, but it's got touchscreen. It's got Wi-Fi It's not particularly fast 200 Meg bandwidth with 1 gig sample per second. that sample rate will drop with the number of bits up to 14 bits I believe it drops down like 125 make sample per second. It's got an arbitrary waveform generator, but it's got like DKI squid C Rs-232 SPI decoding touchscreen VGA Wi-Fi It's got an app which you can scan in and it's got a multimeter as well built in and it's like 1,200 bucks so it's It's not exactly an entry level our price point so it's in a rather niche market segment where really the only reason that you'd buy this is because of the 14 bit high resolution converter you might have seen in my 1000 video.

I Did a comparison of like 11 different scopes that I've got here in the lab and this one performed really well as you'd kind of expect like down in the noise and stuff like that so having done full evaluation on it. but anyway, it did you know, had and did a respectable job as you'd expect from something that has a twelve or fourteen bit convertor in it. So anyway, let's tear this thing apart and see what's inside, shall we? In just a quick overview. it's like a reasonable tilting feet on that the thing.

It doesn't weigh a huge amount and it's really, really thin look at that and a weird, you know, concave sort of aspect to the back of there. So kind of weird. Take out a few screws and whip it apart. Mm-hmm Now there has been some speculation about this thing that it wouldn't use a true 14 bit converter in there, or even our true the 12 bit and that it's just doing over sampling well.

I'm 100% sure that's not the case and it is using a real 14 bit convertor in there. In fact, the converter I believe is an 8 bit, 12 bit and 14 bit converter combo because there's a hit Ayat part. It's the what is it H M Mehcad 1520 and it matches the not only the combined ADC like that up to 8, 12 and 14 bit, but it matches the sample rate of this thing in the different modes precisely. So I believe that's what it's actually using.

So I'd be stunned if it's not that headlight part unless there's some other manufacturer of some compatible parts. So anyway, so we. oh, there we go. That's our battery compartment, of course.

forgot all about that, but of course might be handy if you're using this in the field to do a, you know, high-resolution logging of something like that. But you know, probably if you're doing that sort of thing, you'd probably use a dedicated data logger. But if you needed a high-resolution scope with battery, this is probably the only one on the market. I think Anyway, stand to be corrected.

But yeah, it'll definitely have an itch there. All right, let's lift this puppy out. It should. Yep, Woohoo! There we go.

That's reasonably neat and tidy. See a bit of a how you doing cap just lying on its side like that? I Guess they needed to ask some extra capacitance there. Let's take a squiz. Not clearly all single board construction here.

just this one main PCB which does the front end as well. The cans they might be I don't know I Think we can lift off the cancer? Got some shielding over the top part of that. No, that's no, that's heat sinking. You can see the little heatsink divots on there.

so they're obviously going to the ADC and probably the FPGA for the main acquisition and everything else in the display and and the main application process at Know the application process is down here by the looks of it. So yeah, likely ADC Memory and the acquisition. FPGA Separate power supply and multimeter board. not just the multimeter board.

Yeah, there's a little Wi-Fi module and this thing I think has the tiniest power supply I've ever seen in a scope. Here it is here. we'll have a closer look. but basically I'm this thing mustn't draw much power at all because the battery.

It can be battery-powered of course. So I'm a curious to see how much power this thing draws. Let's have a look 300 milli watts in standby. That's awesome.

VA is going to be higher. Of course there we go. 3.7 VA but that's nice. Now let's switch it on.

Yeah, that's not too bad. around about 20 watts and 31 VA. So 20 watts isn't too shabby. I Guess it's I Think it's probably one of the lowest power ones I've seen and that's in 14-bit mode.

In 8-bit mode, it's basically the same. It makes no difference if we have a look at the output caps on this thing. Why? Men or issue women? quality is our life. Yeah, and there's just some other no-name manufacturer there on the primary side caps, knees basically bugger all on this thing.

I Mean it's only a single rail though, which is why it's a lot smaller than the others. You can actually see 5 point, 5 volts DC at 5 amps output. So basically our 25 watt capable as drawing 20. Watts Oh yeah, ok, no worries.

I'm cute little towel supply. It's ok, you know, no-name caps, but that's par for the course so it all looks fairly reasonable for the price point. but you know there's no input fusing if they just put fuse. Note: they just put a link where the fuse is supposed to be.

We have one semester and that's basically if there's no poly protection or anything like that. But we got ourselves are exposed mains wire in here, but that's all completely covered with the case earth going over to the main point which goes down over to the main, through the Wi-Fi board all the way through to the main plate down here which is the plate which are bolting to the B and C. So that's all quite reasonable. Interestingly look, they've got a wire.

They've got some foil tape on the backside of the mains connector and a wire running off. You can bet your bottom door yeah where is that that's running over to other to end kit. This is our means engine. that's our Wi-Fi antenna.

That's our Wi-Fi antenna. What? Okay, that's a bit how you doing in it. just slap it on the side of the mains connector. Oh goodness.

I Don't know what effect that's going to have on the performance, but pretty terrible. Muriel At first I thought that was like the 50 Hertz I like the mains frequency pick up like I thought they were just using like a capacitive plate and then picking up the 50 Hertz that way. but not the antenna. That's hilarious.

Now let's look at the multimeter. PCB or effectively the lack thereof multimeter. Um, it's a real basic implementation with very little input protection law. This thing actually doesn't specify a cat rating on it.

might in the manual, look it up if it is. I'll put it in, but it basically doesn't specify anything like this is. you know, like Cat 1 low cat to territories like. Pretty like it's not independently certified? Nothing.

As you can see, like there's hardly anything here at all. So let's have a look at the voltage input over here. I Haven't got a real fair dinkum. Really? Okay, sums up for the fair dinkum.

Really? Um, but we've only got one NTC semester here. We've got our two high voltage input resistors here in a little milk package. They have done the right thing. They've cut the slots under there, so yeah, no worries.

Okay, but that's basically your only input protection there. There are no mod protection at all. We've got your traditional which I did in my thousands video. You've got your back-to-back zener clamp with you two transistors there.

They've also cut the isolation slot underneath the relay as well, so that's quite nice. But there's basically bugger-all protection on this thing. That's basically it. Now, if we go over here to the ants range, here's our milliamp shunt here.

There's no diode protection on that at all, and our 10-amp shown here is just our regular Nichrome our wire going across which is man okay, but just don't You know it's a little bit how you're doing, but it does the job right. Just trim it out, no worries. But there's basically none of your traditional diode bridge protection or anything like that. And there's certainly no fuse protection on this thing at all.

let alone HRC Fuses don't even have glass fuses. So yeah, like, you shouldn't even be using this on anything to do with the mains or anything any high powered stuff at all. It's strictly you know, bench type measurement stuff and this little down here that ones doing the isolation. So it's just doing power supply isolation.

Get an isolated power supply for the multimeter chipset, which is a pretty standard of Fortune' semiconductor part. You can go look that up. We might have some extra diode clamping protection here and here. Maybe that's for the maybe the current ranges, but they're not going to protect like it's not even fused.

I Mean, give me a break, that's a fail on the multimeter. Like, why do they even bother having multimeter in there? Ah, now, those keen viewers might have spotted that there's no fan in this thing. Oh yes, there is. Where's the fan? Where's Wally? It's not under the case, no siree.

Bob By the way, there's no side vents, which you'll see as might be kind of important at the moment. Then there's only these are vents on the back of the concave part here. So where's the fan? Can you spot it? Can spot it? Where's Wally? Is Wally right under there? That's probably the worst. Implement a thermal implementation of a fan in this or scope I've ever seen that is awful.

It's like if I believe it's sucking in this way and it's pushing down probably that way and under the board and then where to sleep. Where does the hot air have to go? It's got to spread over here. It's got to come up, dribble up the side here and then out the vents here like thunder. I hear it like it's absolutely ridiculous.

Ah, he did that. Stevie Wonder By the way, they have done the right thing by having this insulating sheet on the multimeter and also on the power supply as well. Fortunately, to get a good look at this including getting the heatsink plate off, is that we go to I've got to undo the base plate here. The B and C's are tied into the base plate under there.

So I'm going to take the whole thing out, take off all that front metal work staff for bottom metal work stuff, and then get to the bottom side of the screws here because two of them are screwed from the bottom side to a screw from the top. So this is definitely a Stevie Wonder design and like, yeah, Anyway, here we go. Ah, can we get that? Oh yes, yes. we're almost in like Flynn Bloody hell backlight.

That's the LCD display for you display aficionados. I Know you're out there and is that the part number for the display? The electrons are falling out and what that thing was originally designed for? I Have got no idea there it is on the front of the unit. It doesn't light up and do it. so there's the front guts of the main unit.

and you see, they've got a separate board down here for the times. 10 detection down here. Got a little ribbon cable going off so that's all just part of the keyboard matrixes and the rotary encoder matrix. That's all just detecting that.

Not sure about the brand on these encoders though, huh? I'm not exactly sure what the Ljv is it. Sure the marking is on that puppy. If I find it, I'll link it in. There's the back side of the mainboard.

We can go through it in a detail and I'm sure we will. but now I can whack the heatsink off. All right Here we go. Oh, we got some goop.

we won't be out as I said. Okay, there's no I'm just thermal pads. Good. Excellent.

Don't have to group s done to clean it up. We can read that as their F PGA Now I Was going to examine this board with the Tigana microscope as I would normally do, but unfortunately bloody. Windows 10 Installed some stupid update on my lab machine here and it's just killed. It got the blue screen of death and it just simply keeps her a pic trying to repair itself, repair itself.

it doesn't bloody work. So time for the macro lens. if you don't know what macro lens I used. So most of my shots except for the Takano I use an optical X Ten macro lens that just screws on the front of my camera like this.

If I can get the thread to light up, it's really hard to get these numbers going to get light at the right angle of a shot at all. China But yes, I picked it. If I had 15 20, that's ahead. I Taught for 8/12/2012 but it's only claims to be a true 14 bit convertor and four channels up to 105 make samples per channel.

So there they got two chips in here. so they're only using the one channel here. Interesting. And they're claiming actually a 11.8 effective number of bits at 105 exsample per second in presumably the 14 bit might or no, actually, you're a bit output is it? right? Next to that is National Semiconductor LMX 2581 and that's the VCO Of course that generates the sample clock.

And interestingly, check out this board here. They've actually got a daughter board for the oscillator. They've got a regular, larger oscillator footprint here, but they've decided to put a smaller one on there now. Okay, you know, design his little daughter board and have that surface mounted on there with a little five pin stop 23.

What is that? a little regulator or something like that? - I They might have had an issue with their with the stability of the oscillator or some such thing perhaps. Hmm. interesting. and by the way, they do have actually won the had 15 20 per channel.

So yeah, that's not going to be cheap and above the ADC is there. We've got a Spartan 6 FPGA and check out the number for those playing along at home. So that's the acquisition. ASIC With the memory either side of that thing, it looks like there would have one chip per channel.

I would be guessing. just check out that part there and put up a datasheet, but interestingly above that and coupled into the main acquisition. ASIC they've got another Spartan six. FPGA Doesn't look as grunty, but that's obviously driving the arbitrary waveform generator because we've got to bird round Dax there and then that goes over.

Got some or is some analog and some really goodness there and that being see there would be the output would be the arbitrary waveform generator output and we've got a million application processing from Toa. Let's check that one out and this is the Texas Instruments Satara process of one of these Arm Cortex A8 jobbies and it's got everything that you can possibly want inside. It's about like less than ten bucks in volume, but it's got the LCD controller which you want building and it's got the touch screen controller which you want building and Ethernet and all the bells and whistles. So yeah, so they're running I don't know what sort of OS they're running, maybe some flavor of Linux Who knows though, that we've got some more hi next memory and then what have we got And then the VGA output there is handed by this cron teleported I think I've seen one of these before the Seventy Twenty Six be so yeah, there's a datasheet.

Normally we've I've seen it driven by the application processor directly or by a some display our FPGA in the past typically. So in this case the VGA output didn't come for free like it didn't come at just the cost of the VGA connector on the back and some and a couple of our passes it you know came at the cost of yet another chip in the ball. And as for the fixed power input here as we saw before, it's actually five point five bucks. haven't actually measured it, but that's what says on the power supply, so they're obviously allowing for like a diode drops.

I Don't see a big-ass diode there to bring in the battery, so they've obviously got some regulation stuff and that cap on its side. The Thunders Under cat? Yeah, great. and it's like just budged on there. So I did they got very little, you know, bulk decoupling on this thing? Actually, it's basically just the two caps on the power supply.

plus with this one and that's pretty much it. There's a fair bit on the bottom if I flip it over here. There you go. So here's the battery input contacts and you can see that this have you know battery charging stuff probably you know, or integrated into this thing and there's probably a chipset that handles the power supply switch over there.

There's no Ethernet port and as that our Ethernet chips sit on the bottom can't quite see that one and I won't bother taking off the shield on the bottom. There's just going to be a whole bunch of our passes under there. Unless we want to reverse engineer the analog our front end, then it's not a huge deal because I have to. Thats actually you can solder down there more relays on the bottom.

a lot more passive are stuff around here, which is the DAC up here for the arbitrary waveform generator. so they're going to a lot of bill of materials expense for the ARB gen output. I Can't remember the specs on that but G's is a lot of stuff happening in there. And speaking of, realize it should like realize everywhere the front end for relays per front end.

another relay over here and no less than five, six, seven, eight relays for the arbitrary waveform generator and the pass/fail trigger outputs. Absolutely amazing. But you know I'm a real a fanboy I'm in my eye NEC one so yeah, but they just sold All their problems was realized and there's nothing wrong. Fun! I Like it.

We won't actually do a detailed analysis at the analog front end, but it looks like you know your typical modern 200 Meg analog front-end You know you've got your programmable gain ant up here and just you know all your regular trend. You know, discrete transistor stuff with some relays? Switch in and it's all pretty basic. There's going to be some extra stuff on the bottom. We've got our solid state relay down there and yeah, it's pretty typical.

If you want to reverse engineer it, go for it. So really, there's nothing hugely special on here apart from the Head 15 2014 bit Atcg and I've got two Spartan 6 like Fpga for processing. Like you know most other low-end scopes do, It seems to be the FPGA of choice. It's got an applications processor which nothing hugely special.

It's got, you know, a basic 200 megahertz analog front-end like you know any other Rygel or Siglent for sub $400 scope does. but this is a $1200 scope so you've got to wonder where all the money's go. You would hope it would be going into the firmware and and you know the software interface and everything else. but as we've seen out of the box it you know was not a good experience at all.

It's pretty much a lots of features missing, fail, didn't work properly and that was just mucking around out of the box let alone a detailed you know, a performance review of this thing. I Mean there is a lot of stuff on here. probably more than your average low in scope in terms of you know, your $400 scope in terms of bomb parts, but nothing that justifies the price tag of this thing. really.

So they're really, you know you're paying for the specs I'm not sure how much they had 15, 20, 80 CSR but so if they're doing a detail bomb cost analysis it you know it looks like it should cost about half what it does. So I think they're charging a premium for that 14 bit ADC There's nothing wrong with that. you know, as long as it's everything's there and the battery option and all that sort of stuff, you know, but like because there's not much on the else on the market, if anything on the market like it. So I guess they can figure they can charge a premium for it.

But and I think they're justified in doing so. If it's a you know, a good, solid, capable scope. and the hardware's okay, but the thermal design of it's pretty poor. Just the way it was all assembled was a little bit how you do and it wasn't nearly as spit and polished as other scopes that we've seen tear downs of.

so not hugely impressed by it. Really? I Mean it's did. It's I mean it's not slapped together. It's not junk.

But yeah, nothing really makes me what. I write home about right? Will it boot? Come on. Yes. we don't win a chicken dinner and the touchscreen works.

No worries. So there you have it. that's the O one XPS 3202 IAE And as you've seen in my unboxing video, like first impressions, not good. Lots of firmware issues and other usability issues.

As I said, I Don't see whether where the value is in this in terms of actual well, you know, component and build cost for the $1200 Apart from those ADCs the 14-bit a TCS And granted, the performance of it does look quite good if you're after a 14 bit Atc. In fact, there might be nothing else on the market like it anywhere near this sort of price point. But yeah, I like. it's nothing spectacular like an 8-bit It's one gig sample per second, 200 megahertz bandwidth, it? you know it.

and there's no mixed signal capability. The objects like it's got a fair bit of hardware in it, but you know and it's touch screen here. might have Wi-Fi in an app which I haven't tried, but I like all wanky stuff really? Anyway, huh? Not going to write home about it, but there you go anyway. as always with these tear downs I hope you learn something and you found it interesting.

If you did, please give it a big thumbs up. Catch you next time! Oh As always high res photo teardown photos of this available on Eevblog comment link down below. Catch you next time.
