Hi, We haven't done the Scylla scope teardown in a while and I've had actually this wonder for a while and I haven't gotten around to it. It's the Unity Upo 2104 CS Ultra Phosphor oscilloscope for channels and that's the key factor here. Up until fairly recently, the venerable Roy Gould Es 1054 Zetas practically had the 4 channel low cost oscilloscope market to itself. There basically was no competition, but now more companies coming out with four channel oscilloscopes including Siglent which I just got this morning a brand new siglent which is going to compete against the Rye Goldie's 1054 Zed and you can expect to see that one very shortly.

It's just under embargo at the moment, but there is information on the Eevblog forum for those who want to seek it out. but I have not heard much about this Unity one indeed. If you actually go, try and buy it, it's really not available in that many places. Um, but it is a 5.

I Believe the retail price is 599 US dollars, which is substantially more two hundred dollars more than the 399 Ri Gold Es 1054 Zed a street price, but street price on this is about 540 dollars from Banggood.com which is one of the few places you can get it apart from eBay so it's not very well known. I Don't know if there's much information out there about it. it has been on the market for a while apparently, but anyway, it is an entry level for Channel 1 gig sample per second scope that's obviously going to be shared across the channels. How many I don't know I hundred megahertz a standard entry level bandwidth, but it does go up to 200 megahertz.

so presumably it's got the full 200 megahertz bandwidth built into the hundred megahertz model. I Don't know about any hacks or anything like that. As always, these things are shared I might do some stuff at the end or a separate video, but they are possible. So anyway, let's have a quick 10 and on this puppy because we haven't torn down a Unity oscilloscope before and I've been critical of Unity stuff before cuz their production quality is very high here.

Miss. They make some good stuff and they make some really bad stuff. but then their hats off to them. They have come good on multimeters and things like that fairly recently.

They're now getting them independently, ul certified and tested and all that sort of stuff. so they seem to be coming along so it'll be interesting to see what's inside a Unity oscilloscope. Let's get to it. and because I know people will want to see it.

Here's a quick comparison with the venerable 1054 said here: it's a little bit bigger, weighs about the same, it's fairly hefty, so expect to see a lot of our metal and stuff inside. And it's The user interface is much less cluttered than we get on the ride, either one. The ROI goal is rightly criticized for its user interface and it's just been a bit difficult to use. So as I said, it's fairly hefty.

It's got the red goo requisite tilting bail on the top. It's a bit yarn worthy doesn't have feet on the front to actually tilt it like that, but if we have a look on the back here, which is rather interesting, it's got these feet here, which just don't. They just flip like that. So I'm not sure what the deal is.

Um, it does really make it and not. You know, dude, this thing is not gonna fall over at all. This is like absolutely incredible in terms of our stability. Really feels good now.

these feet do actually lock into place. You can actually put them down like that and it's It's very straight, but like almost to the point where it feels like it's tipped forward. Maybe if you you know you had it up on a bench or something like that, you use it in that configuration. but otherwise yeah, feed out anyway.

Ethernet standard on the thing. You got your mains with a little switch on the back and external trigger and pass/fail output as well. 30,000 waveform updates per second are claimed on this thing so you know it's it's pretty well. Specs: 32 mega sample Mary as standard so that's awesome.

That's beats most low-end scopes on the market. Problem may be all of them I'm not sure. 100 V a max G's gonna have to measure the power consumption on this thing. Looks like a big ass fan on the back.

You can all the metalwork I've got a Kensington lock there and that's about all she wrote. anyway. You know who say you're on the Eevblog? don't turn it on, take it apart. Oh I didn't even see the poor Annie voyage sticker on there.

Ah, screw that we're not in like Flynn yet. as I said, all metalwork. Fairly hefty little beast. Very typical construction of all low-cost our scopes.

I'm not sure if they naturally evolved this way to have like the big mainboard and then there the metal shield on the back with the screws around the side and then the metal shield lifts off and the power supply is usually bolted onto the back. Here you can see the the standoffs, the integrated standoffs in there, and then it flips up there. It's pretty much par for the course. Not sure if they've copying each other.

Oh, that's just a natural engineering evolution of these types of scopes. Anyway, as for airflow on this thing, air comes out the back here. sucked in from only the one side over here, so it's going to flow presumably all over the power supply, processor and out this side. so that's not bad.

Yep, yep, she's gonna come off. There we go. We are in. Oh hang on.

Hate it when you go to unclip to get in like Flynn. Now you have it. we are in like Flynn As expected, just a single board construction but geez is not much on there. He said little heatsink here for the FPGA that closer look.

Anyway, it looks like we can get the shield's off the front end. That's a pretty decent layout. I Don't mind that at all but capacitor down here Ben over that's a bit how you doing and it's so close to this 32 kilohertz watch crystal here that they've had to put the little insulating sleeves on there. Hilarious.

Like what the hell? somebody's put the footprint. Lay it out, the board and the footprint for the crystal is inside the vertical footprint. Oh well. I guess it's in the know.

It looks like silk screens going off here. so they had the intention and I guess those lines indicate that maybe it. Oh no, the sudden L couldn't indicate the negative side there. but like so they had the intention to lay it flat.

but just laying that across there I Just think that's hilarious. anyway. anyway they have gunk that down haven't left a flipping around the breeze. Nice.

Let's have a look inside here. it looks like they might have rolled their own power supply which is not that common. Mostly you farm out these things but anyway, well they could have still thumbed it out on a no as they ke see to I don't know there an even there. Maybe that's the manufacturer.

Maybe that's the designer and manufacturer. Maybe they have farmed it out. But anyway, it looks neat and tidy I Don't mind that at all. Of course I took the shield off to get at this not can say I'm a big fan of the earth just going over into the connection over here and going down via that.

Probably would have preferred a direct crimp and connection and a director you know, stud on there and screw, but you know it's fine. Oh, got some heat shrink over there. obviously. we got a got a few Z in there.

Yeah, Five by Twenty Few is vertical. Geez. you've got plenty of room in there to put a fuse holder on the board like tight-asses Unbelievable. Anyway, he'd shrink around a thermistor there just to contain it if it explodes.

It's got all the records of stuff you, common mode filters, everything else. The transformer who does that I don't know. Same company makes both at least and our requisites Sam Wire caps. You know they're par for the course.

Are these ones similar down there? No. What Are they mimics? They look like same wire as well, so at least they've matched 105 degrees. See, yeah, she'll be right. I Guess don't see anything offensive on the back here.

They've got the high-voltage isolation slots across the Diode bridge. There there's the earth going over to the stud there. They've got the cutout in there. They've got the cutout under the trainee here, and well, that's all she wrote.

It's all isolated nicely and nice attention to detail. They've got the elephant tied on the bottom. they're not elephant hide. that's pretty cruel.

elephant tied insulating sheet for those who don't know. and there's absolutely nothing doing on the Ethernet and USB and IO board down here. They've just got the two pin header goes over to the pass/fail and whatnot output. so there's only two boys on there.

So where's the return path? I Hear you ask? Where's wally? The Shezzy Earth? Thank you very much few fan aficionados I'll let you guess that one. I Couldn't be bothered unscrewing it to find out. Quite frankly. All right, let's have a look at the main board under the Tigana microscope Here, it's our version 1.0 Seven things ever had.

Several sucks at the serve which is not uncommon of course and all the caps around here. These are wet electrolyte tights because you can see the cross the vent cross mark on the top so you know they're not solid aluminium electrolyte capacitors. Got a couple of low dropout voltage rigs. They're nothing special that looks like it's the LCD does it coming from today.

The main applications processor throw you Toa fanboys there. It is right there and that's a bit of a beast. That's the Satara line Arm Cortex A8 processor up to one gig. Vader will have to look at all 100.

There could be the one gig model. Anyway, we've got all the termination resistors over here for the driver, but looks of it and you can see we've got coupled into some micron memory there. We'll have to put that into our part digger micron part decoder, but you can see all the little squiggly traces in there, try to length match all that DDR Ram into the main processor there. But yeah, that wouldn't That's not your sample memory, so don't get too excited about that and you can see all the traces.

bugger And off. over here there's some JTAG pins do we have? any way they're going - this puppy over here and that's a national semi. a T-38 for eight. that's an Ethernet thigh.

so that's buggering off - via this ribbon cable here. back to the rear panel which has the Ethernet and whatnot on it and goes a little fusee in there. Ah wonder what that's doing? A couple of inductors. Anyway, here is our memory.

so that's our sample memory 6 YJ One seven. That's very different to the one that we had over here on the applications process of this. so this will contain our 32 Meg samples. Let's decode that.

So as it turns out, that's A in MT 41 K 64 Anyway, blah blah blah blah blah. Sure enough, that is 32 Meg per channel because there's 8 bits per channel. Awesome! I'm so there's obviously no second one on the bottom. They're all sample memories inside that unless there's another one for like the phosphor display and other stuff like segmented memory and things like that mm-hmm And above that is our mystery FPGA which you take a look at and then just love all the matched lines.

Beautiful thing of beauty is a joy forever. hold the Wonka 'mobile thing of beauty is a joy forever anyway. I'm the Cypress Cy7 see 1360 that is a 9 Meg bit 256 K by 32-36 pipeline to SRAM so that'll be doing all your fast sampling and that and then I'll be dumping it into the sample memory or whatnot. So yeah, we've got a bunch of fast SRAM attached, as they always do in these scopes.

And of course, there's no surprise for guessing what's coupled into the other side of the FPGA there is the head 1511 or H M CAD 1511. Let's take a look. that's the HM CAD 1511 Analog devices. We're seeing this like time and time again are practically every scope on the market.

In fact, they're the typical applications digital oscilloscopes are. That's pretty much what they're titled foar. And yes, single-channel one makes sample per second. They're doing nothing fancy.

it's all done in here. It's just basically you know, off-the-shelf app note type stuff apart from the front end which you've got to roll your own, everything else and the stuff you got to do in the FPGA the phosphor technology's sampling technology, things like that. but apart from you know, the ABCs they're just all off-the-shelf stuff. And yes, if we turn on all four channels I don't even have to power it up to find out.

it's going to limit it to 250 mix samples per second, which is going to completely suck. If you've got the 200 megahertz bandwidth, it's barely acceptable. In fact, it just is technically acceptable for the 100 megahertz bandwidth 12.5 times the sample rate there with sine X on X interpolation. that's good enough.

but for the four channels, but no good for the 200 megahertz bandwidth. But we've seen this in other scopes, so it's just par for the course. That's what you get in the low-cost scopes Because these chips are expensive, they're not going to have two of them dedicated in there to the two separate channels. It just costs more.

You can't get the price point. Oh, what's that? I'll give you one guess when you've got a single differential pair going out like this and looks like you've got single line coming in and all these resistors and caps and a couple of inductors all around the outside. like that that is our PLL our phase lock loop that generates our word one gig sample per second. So I'm asthma famously Rygel Actually I screwed up some parts in this and it wasn't very good.

They managed to fix it in software in the internal work registers. But anyway, for those who I know, there are people who love to decode these sorts of things and check the the values and things like that to see if they've got it right. But yeah, you don't know unless you got all the like, you can goof it up I'm you can check. but yeah anyway, let's get a part number on that.

It's really hard to get the light right there you go. I've got to put my hand. it's the glare from my lights overhead. the ADF 4364 those playing along at home.

Seven. There it is the integrated synthesizer and VCO I think it's the same one we've seen in other ones 350 Meg 218 Meg output frequency range. So yeah, it's all par for the course. and then like I said, you can go in and have a look at all the registers.

Things like that, it's all you know. Here's all your reference input section, blah blah blah, how to lock it and all that sort of jazz. But here are your registers which if you don't set up these correctly, you can come a gutter or you can potentially fix Hardware Goofs like happened in the Rygel you know. I'm sure they're probably fixed it in production like newer units, but years ago when they goofed that up yep, they were able to I just pull a few little tweaks in the registers I believe to pull that sucker back into lock.

So that's obviously a differential output diff pair running down there to standard Fr4. Now this controlled impedance dielectric rubbish. Um, and that just goes into our ADC down there. So that's about all she wrote.

Let's move up here, shall we? This is the AH hello hello Mr. Botch. Anyway, this is all above the front end here. I'll show everyone wants to see inside the front end, but this is all the stuff at the top here so this will be trigger stuff.

this does not. This one does not have any option for mixed signal for like a function, gen, output, or anything like that. Oh, we got more up there. There you go.

Do that. Wow. it's all over the shop. What's that? And that is does Voices 56:28 Let's go to the datasheet because I'm shooting this on one monitor here.

Have booked up a second wonder. I've got to go oops over there anyway. Um, that is a a dead stack Whoo! 5 ppm per degree C with the on ship a reference. Very nice.

So that's doing all your offset stuff and things like that so that's not bad little deck. Wow Anyway, that's a real interesting block there. so I wonder what going on there? Anyone want to reverse engineer there? There's a bunch of discrete trainees and things in there. We're going to salsa suspicious-looking diode over here, but that's interesting, huh? They've got some sort of some sort of amp.

Some sort of discrete and for something like that perhaps? Anyway, let's go down here. We've got another one of those. Yep, we've got another one of those DAC jobbies. and I got to have a four.

Oh Five three. Everyone still sell those by the bajillions and they're in everything. They're in absolutely everything. So then we go four oh five threes.

Again, nothing special, nothing special. Geez, it's a big different 4004 Oh 94s. Yes, thank you very much. Beautiful.

And we got Dax coming out our rear end. well, that backs all over the shop. Anyway, that's all the support stuff. Nothing particularly high frequency, but look at that budge job Wow what they've whack do you know and cap across there and looks like they've done a trimmer.

Is that a triple stacker? I think we have a triple stacker and I think it's only a double stacker. And of course, here's what a lot of your aficionados want to see the analogue front end in: Glorious HD bit of flux residue left there, but we'll excuse them for that. Looks pretty par for the course, doesn't it? Yes, all the channels are identical. Place spot the difference.

high-res photo? No, no, no, no, not quite. Not quite because you'll notice that there's no big chip in the corner. that's probably a MUX for the digital lines. We're seen this before, so there's slight differences, but the actual like in terms of just driving they've you know I shared a couple of these IO digital I/o expanders probably across I Think you'll find that part number in there is probably at nine.

No, it's a MUX it's a MUX Anyway, they've shared those across, but the actual set of bodge, we've got one. I Got a bunch that? yeah, we got it down here as well. Not what's going on, No one, they're not so good. So what? What on earth is going? What is that? Have they done? It's like a cap in there instead of a resistor.

what? And of course the main job' we want to see here is the LM H 65 52 and do believe we've seen this before. 1.5 gig fully differential amp and that drives the ADC and that provides the gain for the various ranges. Ended there you go: Differential A DC driver. You know differential line driver because that's basically what it is doing there.

So it's taking the 50 Ohms single ended a source here and basically giving you differential pair over here into your ADC. In this case, they shone a 14 bit job. but yeah, that's I believe we've seen that is that part or very similar in most of your low-cost scopes on the market. Not only in addition to that, you can see several other sucks of the serve here.

Look at that, what's doing there? Someone's had a go at that. Thank you very much. And yep, down in this channel again. get that Three Secret: Are they the same there? yet? They've added the 365 so They've motored those after the fact.

somebody's hand soldered those and they decided no it. We want to change that resistor after they've done their reflow production and changed everything anyway. I'm genuine Omron relays and there's a little tremor caps and we've got our solid-state relay down there. Oh Par for the course I Think if you reverse engineer this, you'll probably find that it's very dissimilar to most low cost digital scopes on the market.

And at the end of this video linked in, a very interesting reverse engineering of the RAI Go RDS 10:54 front end. It's been a very popular video. A lot of people like that one. I Won't bother reverse-engineering this one though.

Leave that up to someone else you thought I'd forgotten, didn't ya? Let's get in there and wipe it away. Surprise surprise spotting 6 FP G IX C 6 S LX 45 For those playing along at home, I play the exact part we've seen in other low-end scopes. Geez, got the design win all over the shop. In fact, is there a single scope out there that uses an Out Era part? I'm not sure if there is.

Hmm. so there you have it. That's not too bad at all. It's exactly what you expect in a 4 or $500 class scope.

We've got the same ATC's the same, Fpga is the same application processes, the same front-end drivers, and everything else that you know, the same memory, Everything else that you'd find in practically all of these low in scope, so there's not much difference. The build quality is fine, no worries whatsoever. It's all going to come down to, you know, software implementation things like that I suspect and I'm not actually going to take the board out any further. I'm not that fast.

There's going to be, you know, bypass eye caps I Don't think there's any more memory because we saw that the memory could handle all the channels. the 32 Meg's per channel I think so I Don't expect to find much, if anything interesting on the bottom. So yeah, I just want to get around to pairing this thing up. Takes almost 50 seconds to boot.

It's infuriating. Anyway, what does a draw? 44 VA and 26 what? Geez, that's not terrific power factor is it. But anyway, our 26 watts. So that's um, like it says, like a hundred? No, what says a hundred VA on the back didn't it? She's not even drawing half that and 2.13 watts in standby.

That's at least a trip to the moon. Seriously? Mars maybe. And for those wondering, fan noise on the thing, not as bad as the wry goal. 10:54 said it's not too bad.

You can like in a quiet lab you would hear it. but you know, look, if you want to put a saw and fan in any of these scopes, by all means, just take it apart. Screw the warranty void sticker and change your fan. Or you can cheat with the warranty void sticker.

I've done a video on that I'll link it in at the end. Stay tuned. What the hell is this? This is to select show which channel is selected. They put this like weird gradient thing right through the center of the stuff you want to see.

you want to read. Unbelievable. What idiot thought that one up? I Find the display quite bright and no easy to read. Don't mind it at all.

This is interesting. Look on the Yo channel information here. we can. Actually, if we go into next, you actually set a bias voltage.

Look at that. That is fascinating. We can set a bias voltage on the front end I Don't think I've ever seen a scope do that. and of course that is different to our position.

Like that we can set a DC bias. Wow Hmm maybe to use to shift that? you know if you're measuring. If you want to keep DC coupled, you don't want to use a C-cup Would you want to keep DC coupled and then shift it into the range of the ADC perhaps? interesting. And I'm trying my standard waveform intensity thing with a 1 megahertz our carrier width modulated at 1 Kilohertz 100% just to check the the 256 level.

Wow Ultra Phosphor intensity display. Look at this. Look at these black artifacts. This is Not the camera I'm actually seeing this.

Greed is disappearing in the background. We're 2.8 Meg depth on here and look on this side here. it's like chopped off and I don't really like the way it overlays there. just with the black.

it just looks like waste chopping off the graticule. there. you can get rid of that. but like and the waveform look over overlaps the grid on the end here.

I Don't like that at all. And if I do the intensity modulation I mean it's it's good. It's I'll show you compared to the Rye goal in a minute. Yeah, no, it's okay.

It's got the nice bright spots in the center where they're supposed to be. It's not the best I've seen, but it's certainly quite adequate. anyway. It does have a couple of interesting things like that: DC bias that we saw there.

That's I'm not sure of another oscilloscope that actually matches that. Um, I stand to be corrected on that, but anyway. Um yeah. I did this won't be a review? No.

I can't go into it anyway. What It does have another interesting thing. Independent Time base turns all four channels on and we can modify those. Presumably we've got four different time bases.

modify those independently. It it you cannot switch off the channels function is disabled in independent mode. You've got to have all four channels on, but you can get different time basis. There we go.

That is neat. Channel One change. Yeah, Channel three all the way with LBJ maybe. Anyway, it's got a few interesting features, but yeah.

memory depth. use sample modes your serial decode. so I don't believe your serial function is disabled. Yeah, they sent me a review.

Scope doesn't even have serial decodes so presumably I've got to go in there and figure out what the hell is going on. So Mamita brilliant and trigger select IP Config real-time Dayton Clogged DDS function is disabled. Where is the DDS There's a hardware and software version for those playing along at home anyway. I hope you enjoyed that look.

let's give it a auto shall we see what happens? But anyway I hope you enjoyed that teardown. If you did, please give it a big thumbs up. As always, a high-res teardown. Photos available on Eevblog dot-com which links to my Flickr account and a lot of people use those photos to like do reverse engineering and hacks and things like that.

I Have no no doubt the full bandwidth in this is that front end has the full 200 megahertz bandwidth can be hacked. Um, my initial impression I don't know I have to play with it some more. The hardware's ok, the look and feel of it not. you know it's a little bit too like but it's got all the requisite stuff.

but the price point I Hate to say it but you know 599 retail 540 US street price for a forger I Can't believe I'm saying this, but it is almost 2018 now and a four-channel 100 megahertz scope with doesn't include the serial decodes, everything else is four hundred and ninety-nine bucks. whereas the Rye gold granted it's the lower bandwidth one, so you're not quite comparing apples and Oranges there. it's 50 megahertz as opposed to the minimum 100 here, but of course there I Go has the famous hack which everyone which gives it the full memory depth of the full bandwidth, the full decoding capabilities, and things like that I Believe that's still a thing, which is what's made it wildly popular. But from my mind, the thing that differentiates a scope on the market is the number one thing is the number of channels and it's interesting that more players have came in to try and compete with the own.

Try Go here and as I said, siglent have a new one and I think GW in stick have one and a couple of players so it's almost shoot out time is it for entry level for channel scopes, but this one is quite pricey. So yeah, edit one: I have everything for free and it doesn't even have the serial decodes. whereas the new Siglent which is going to be cheaper than this for channels hundred megahertz, it beats this on price and it comes with the free serial decoding. So yeah, I don't know where this leaves the unity in the market and doesn't really have anything hugely special about it.

So yeah, it's gonna have a hard time in any shootout I suspect. But anyway, look out for the siglent one coming soon and I'll probably have to do a video playing around with this thing and I might I don't know if I'll leave it for the shootout on. do a separate mini review or something like that because people keep asking why don't I reveal your review scopes. They take a lot of time and effort.

It could take like a week's work to properly review a scope and things like that and with stuff going on at the moment I don't necessarily have the time to do that. but anyway I'll see what I can. maybe a mini review playing around anyway. Hope you liked it.

Catch you next time times Bass I Just noticed that times Bass Chinglish at its finest I Love it. but it doesn't seem to have an XY mode like yeah. We've got the independent mode which is independent time basis for the all the channels which is cool but like like I can't find the XY mode. What's what's doing, what's doing I Don't get it.

What people still use XY Mode: Give me a break.
