Hi, You've probably noticed that we've been on a 12-bit oscilloscope frenzy lately. It's like every company sent it in their 12-bit oscilloscope thank you segment. Uh, this one just magically turned up but a little while ago actually I just unboxed it uh the other day. So this is the SDS 2354x HD or the 2300 X HD Series So it's a 12-bit Joby 350 megahertz, bandwidth starts at 100 megahertz and uh, two gig samples per second.

So it's not like you know, hugely high performance like that new Mxo uh Rodent Schwartz Mxo series scope we uh saw. but um yeah, this one starts at about uh 3 200 bucks for the 100 megahertz, uh four channel one and the one you see here is about five grand. And now unlike the Rigol uh, we've seen two 12 bit oscilloscopes from Rygal and one is of course the uh, the 1000 series which starts at 999 bucks so you know, but that is not expandable at all. Whereas this one is at least expandable with your logic analyzer.

and also, you're probably wondering where's the ARB generator? Well, it's on the back here so it does have wave gen does have external trigger does have Ox out does have uh LXI uh Lan but even if you want to compare it to uh, Rygold's Uh 4000 series which is their higher end uh 12-bit a unit which I think's similar sort of price point, but it's not expandable doesn't have the logic analyzer or wave Gen capability so both of Rygal's 12-bit offerings are just a basic oscilloscope. so yeah, at least this one is Expandable anyway. I Do like these sort of like squat uh look of it here. obviously you know with four channels you can't and a large uh touch screen, you can't have like individual uh controls like this.

but you know I Kind of like the look of it. It's a bit chunky but it kind of, you know I I Rather actually like the look of this one. apart from um, the the font here just looks. everything just looks like ordinary and not very professional.

Is that just me? remove film before use? Well, we'll do it before the tear down. so let's go. Oh yeah, look at that. um that is a matte finish screen.

so yeah, not hugely reflective. so thumbs up there. and we'll take off these protective things here. It does have uh, times 10 uh.

probe detection? nice, but you'd expect that for uh, this sort of uh, price point doesn't have active Pro but interface though. get rid of those. Oh this is the best part. Calibration void is seal broken? Come on, where are you? Oh there we go.

look at that. Oh that feels good. Oh look I could have just peeled that off and stuck it back on. Ah well, they do have Loctite Nice By the way, if you do like to take your own gear apart and I highly recommend it.

don't turn it on, take it apart. Yeah you can just buy like um, cow stickers so you want to peel the sticker off and it doesn't come off. You can, actually, uh, clean it, usually clean the residue off, and then if you ever want to resell it, you can just buy like a generic warranty void sticker. No one will know the difference.

I Don't recall seeing another scope that has screws on the handle like that. Okay, this is not as easy nor obvious as other. Scopes Um, do I have to take these off? Maybe Yep looks like I have to. Okay, that's lifting up, but don't know about the top.

Wow, There's something you don't see every day. Look at this. now. one of the screws were there.

This is a die-cast alloy handle and they're obviously putting that I presume that just goes into the plastic there and that's what was I think that's what was holding in the top? Yep, wow. When was the last time you seen a die-cast alloy handle? Unbelievable. Maybe it actually does go into the metal in there? We'll see. Yeah, that's really something.

There you go. That's what we expect. There's nothing else in the case there for your case aficionados. Yeah, Sure enough.

yeah, look at that. Wow. They've got big solid metal things for the handle that's just incredible. Okay, is this gonna set a new trend for Scopes They're going.

Oh the Signal's got a alloy handle. Can I have an alloy handle please? So I wonder if there's any other old school uh tricks inside this thing? Let's find out she. Geez, No wonder it costs a lot more than the Rydal spinny spin spin. Yeah, it's got locking washers.

Oh no, it's only got one locking washer. Ah okay, does that lift off? There you go. We've got one cable coming out. Oh look at that.

there's our uh what board Is that? Ah okay. yep, that is the wave chip. That's interesting, isn't it? Wow. I've never seen a separate wave chin board like that.

that is fascinating. I'll get some high-res photos of course all the ways available on the EV blog Flickr account. Like the uh, coax going over there. That's that's just beautiful.

Um, but yeah, they haven't bothered to uh Shield that individually from like the rest of the unit. But as for an outside product, it's all shielded of course so no workers. but that's that's fascinating. Wow.

Oh, and we've got an open frame power supply here. Wow! this is I'm really liking the look of this. This is absolutely different to other scopes on the market. Um, anyway yeah.

open. We'll have a closer look at the open frame uh power supply over here. but uh yeah. they've got a separate external uh trigger board and stuff.

so that's a vertical uh Riser board there and this has look. they've got a coax going off there. where's that going to? Let's go into something else. oh that'd be good.

that'd be connecting over to the main uh board and down here you've got your opto coupler trigger board. They've gone to a lot of effort there. I'm really I'm very surprised by this scope and look at these um standoffs on here like they've got the standoffs. Um, they're pressed into the uh bent part of the metal chassis there and to mount that board on it's beautiful.

So our Mains input connector down here, nicely mounted like this. nicely earth like that going into a rivet, uh in there so it doesn't have a screw. Um, so that's just a right angle Spade lug riveted onto there and then nicely crimp Terminals and we've got AC here. in and then it looks like, um, just is that single or double row I I'm guessing that's just a single rail like 12 volts out of there and then they've got it going into this little board here.

that's got some unpopulated stuff there. so they've just got like a bypass cap there and that's it. Nothing on the bottom, so there's like no fusing on that board. Yeah, I they had something else in mind.

This goes over here. Nice cable ties, nice attention to detail even down here. Stop it flapping around in the breeze and then that's just. uh, 12 volts going over to the main board.

Um, that is really quite remarkable. Anyway, if you fan aficionados, uh Delta um Delta a pretty good brand. uh DC you know, Chinese brand, but they're pretty darn good. They're reputable, at least not just small things.

I Noticed like this is just like a pivoted alignment pin which seems to match up with that PIN But I don't see how it physically helps. apart from, yeah, assembly alignment. why would you go to that amount of effort somebody? Guild of the Lily Well, they really wanted you to know who manufactured the power supply. It's uh, mean, well.

and they're very, uh, reputable. Um, and yeah, it's look, You know it's got all the requisite uh, certifications and everything. And yeah, they really went to town are like the Heatsinker folded heatsink bracket over there. it's it's anodized and everything.

Um, along with this one over here. so I'm not sure what brand that cap is, they're covering it up there. Leave it in the comments if you know. Um, Anyway, common Mode: uh Choke By the looks of it, it's got all the requisite uh, X and Y class caps.

and yeah, it's really compact though. Now it says 120 watts maximum on the back of the scope. so you know operationally it might be I Don't know, 60 watts? Something could be half that, don't know. But yeah, nice little compact and it's so compact.

this is labeled FB here. the feedback flyback. Um, they've got that going over right under the cap there. And of course, the cap is off the board.

so they've really tried to keep the footprint of this thing small. um anyway, it's got all the isolation slots and everything. Everything looks hunky-dory don't know, over voltage, uh protection connector there. so I'm not sure what the deal is there.

um adjustment pot there so maybe you can trim your uh, presumably uh, 12 volts out. It's got a little operational lead there, but um, jeez yeah, that's pretty funky. Passed why? I mean you know they had a bit more room there. so I don't know.

Is that like an off-the-shelf Joby uh, wouldn't surprise me now. I'm sure that I was just, uh, well, complaining I guess or highlighting in previous uh scope tear down videos that um, yeah, they all sort of are manufactured the same these days and there's no differences in terms of physical construction. You know they're all like a single board and they all open, uh, the same way. And this has been true of uh, Segland and Rygold and other, uh Brands and well, this one is just, um, surprisingly different.

So yeah, I'm I'm really liking this I Like seeing uh, design variability like this because it it, uh, this is why Tear Downs are interesting because you get to see different methods used in construction and then you can you know store those away in your mind for uh, when you have to design products and you go oh yeah like uh, you know this idea that this company is doing this thing and then, but I like them. but I didn't like that one So there's still one little uh design touch from one manufacturer, another from another. and um, yeah, it's really. oh, is that going to come off? Have I forgotten something? Uh, all right, you look beautiful and once again, you can see those alignment pins there isn't that neat.

so they've put those in. uh, looks like to save production time so that your holes then line up the holes for the screws so you don't have to dick around because yeah, there's a gap in there and there's a gap at the other end as well. So if you put it in without any sort of like alignment there, then you're gonna, you know, waste time in your production, step around trying to get all your holes, uh, to line up. you can end up stripping threads and doing all sorts of annoying stuff as well as wasting time.

and yeah, um, that's a really nice touch. anyway. uh, airflow. thermal wise, it looks like, uh, of course.

uh, air comes out the back here like this. Um, so it's sucked in the sides here. They've got one on the side here as well. Looks like that Grille up there doesn't really do anything in terms of uh, that.

So yeah, it is flowing over the heat sinks the heat sinks send to be in the right direction like that I can see down in there there in in this way so it's sort of. yeah, it's getting over the fins and let's pop the hood on this. How does that? Ah okay I need to get a couple of ribbon cables out there. there's the power connector.

There you go, We're in there. you go. We've got five, uh major, uh heat sink, heat sunk devices and two giant metal cans. Hang on.

One second, what's going on here I thought this would be like an internal can I could see that was that Grill I was telling you about there that Grill goes into this. it's sealed on this side, this side and this side so it's designed to get air. How? I don't get it if it is blown out the back. What? it sucks some in Oh I think I get it.

this is some sort of thermal got like um, egg duct guide for all this stuff on the top right? we're we're talking power supply here and we're talking uh you know well here over this is in there as well. You know there's a bit of heat generated in the function gen here. although this vent here that doesn't do anything because there's no matching vent on the outside here so I don't know why they added that, but um, is that sort of like a change in design? Halfway through the process we were going to put like a matching uh vent on the back of the case, but then we decided after testing to change it or go for a different thing and they just left it. They didn't want to, you know, change the tool in for that or whatever.

So yeah. I've never seen like a like a power supply on top like that the fan here. So this power supply is cooled by sucking the air out of. this is the events on the site line.

Yes yes. Look there's larger vents on the side here. Okay so there's air coming in here, but only on one side, so air coming over the power supply and then to get it out through the fan. it's got to go down into this vent, through and then through here like this and then so and then is guided and sucked out through the fan here.

Wow, um hey, you're well. Is this just like really remarkable? It's so different to other. Scopes I I'm just finding this absolutely fascinating. So there you have it.

We'll have to take a high-res photo and then do the uh talking Dave head thing. uh once I remove uh the heatsinks here, but obviously we've got ADC ADC uh and then the Fpga up there. Um I Don't think they have a custom Asic in this. Uh curiously, there's a lattice there that looks like it's driving.

That is that like an LCD driver? Maybe that's how they get faster, Do they? Are they using that as sort of like a way to pump the uh waveform information directly into the screen. So this is called the atom that's obviously their code name for this uh architecture here. but uh yeah. Really nice board.

Liking the look of it. Um, so so let me get the cans off. Actually, these clips are not trivial to get off. I can't just bend them and I it looks like I have to like, maybe bend them a bit first before I can get them out.

I've never had to do that before I Don't think. All right, let's take a brief look at the board here in glorious 4K Screen capture and uh, you can see here obviously ADC ADC they're National semiconductor jobbies. got the main acquisition Asic Here you've got the acquisition memory. Well, actually, they're very different.

That's the acquisition memory and that looks like some firmware for, um, a little processor core running in here or something. presumably because that is that part is very, very different. Check that out. So yeah, yeah, they're definitely different then.

And as as I said, we've got this Lattice jobby over here which is very close to and you can see some resistors here very close. This is the LCD Can connector going across, so you've got to assume that that is somehow doing the mapping for the screen. And maybe you know. And my thought is is that they're dumping.

This is how the Keysight works. but the Keysight does it all in its Mega Zoom for uh Asic um, it might just be using a direct dump in there like that to get the waveform data out of well out of memory into straight into the screen like that. And that might be how they get in their fast waveform updating. Anyway, that one is not particularly grunty because it doesn't have a heatsink on it.

And then we've got a Xilinx Zinc over here. So yeah, um I don't know why they need this plus the Zinc over here. And then of course the Zinc has the Arm R processor in it and then it's got a crap ton of memory around there. So so yeah, it's a rather uh, confusing architecture and obviously this, uh Spartan down here.

this Spartan seven that um is running the Linux operating system inside presumably and um, or maybe actually no, I think no, the Zinc would be running, the Zinc would be running the thing. So what's this Spartan 7 doing? Well, we can't see on the bottom of the board. Here's the logic analyzer connector down here, so maybe it's got something to do with that. Perhaps I don't know.

Interesting. Anyway, Um, that's basically all there is to it. and the front ends. of course, the 350 megahertz front end.

Now, let's actually compare this to the uh, well, you can still get it. Um, it's not obsolete, but the non-hd version, which this is the SDS Uh 2000 plus series and I've done a video on that or done a tear down video on that and I'll have to link it in. So here's here's the two. We can swap between them.

like that you can see significant differences. They've got a smaller ADC down here because once again, this is an 8-bit uh, dual channel uh Joby as opposed to the 12-bit one that we've got now. hence the bigger heatsink and everything I Write this has a giant heatsink on it and it's much more gruntier. we'll have might have a look at the data sheet of that in a minute and then instead of having that one big Artix Capture Fpga which is here by the way, couldn't see it there, but that's actually an Artex 7x C7 A200t, a 1156 pin Joby thank you very much for playing.

and yeah, as you can see that Micron memory there is very different to this so we could have a look at that I don't know who makes that actually. So yeah, instead of one being acquisition Asic they've got two of them. um like that and then um I don't think I I don't think I took the did I take the heatsinks off that I don't know, you have to watch my previous teardown video. Maybe I did, but in the high-res photos here I don't have it anyway I think that's is that the zinc uh processor that the application is running on.

Once again, they still have that ladder so it's a similar sort of thing acquisition Asic and then something else doing up here and then the mysterious lattice one which is that? Yeah, so there are significant differences there, but if we have a look at the front end now, we can actually compare the front end between the two of these. and the top here is the older one and this is the new 12-bit jobby and you can see that there's nothing in it. There's a few little like component differences in terms of like that transistor. there is like flipped orientation and stuff.

you know just tiny little layout. things like there those that pair there is like so if they are a pair they're side to side and they're offset a little bit here. but basically um oh no, hang on. it's an extra transistor down there which is not on here, but geez it's it's a very similar architecture.

front end slight differences in there and there's their input termination resistor and you know AC coupling and stuff they'll have. do they have a separate uh 50 ohm uh path and things but um yeah, near identical between the 12-bit and the 8-Bit version because like there's nothing special. maybe it's slightly lower noise floor, but that would be you would get that in a different part for your programmable gain ampere. and maybe you know some of the discrete transistors you use and stuff like that.

But you know all the magic happens in the PGA here. the program will gain amp. but um, yeah, there's no. it's not really a difference in there.

Um, and I can't quite make out the number on that one. Didn't get the photo in the right orientation, but there you go. That was then that semi Joby before and we've looked at that previously. I'm sure I don't know if I found the actual partner.

it's got one of those obscure part numbers I think but there you go. So yeah, all the magic um happened. And of course over here on the new um, 12-bit analog to digital uh converters so we can have a look at that. Over here.

here's your PDF and uh, there it is. 12-bit uh two slash 3.2 gig sample per second. ultra high speed ADC um May 2010 There you go, it's it's. nothing new, um, but you know these would be pretty pricey.

Oh, come on, they don't have it in the application down here. Put crows, no, this is oscilloscope rubbish. There you go. It's actually got programmable uh offset in there.

That's pretty good. Wow. It's got programmable uh time adjust feature as well. So yeah, this is is this is really neat anyway.

Um yeah, that's a jewel. uh, channel one. But and although this is a two gig sample per second, in fact, I can do 3.2 here. It's configurable as either a two gig sample per second, interleaved one.

So uh, you've got to use both Uh channels or one gig sample per second. uh, dual. ADC So um yeah, if you're of course got channels one and Channel two turned on here, both of these share the same ADC Like this. so uh yeah, your sample rate's gonna half if you turned on.

This is why most Scopes work like this. If you want your full sample rate, you use channel one and then channel three goes into a separate ADC Now somebody on the EV blog Forum actually asked, uh, why don't they have or like, why doesn't Channel one go into here and Channel 2 go into this one over here and Channel three go into that one and Channel four go into that one so that you know most people are going to turn. If they're going to use two channels, they're going to turn on channels one and Channel 2 here where you can probably see the reason. It's a basically um, Elegance of layout.

Here you can see that this is the differential pair. You can see it here. This is a differential pair running into the ADC So this is the program we'll gain amplifier. Okay, so it converts single ended input here.

I.E Grounded and it converts it into a differential uh driver which then drives on this differential pair into the ADC Like this. Now, of course there's nothing Stopping You Routing that over to this ADC over to here like this. But then you've got to run Channel 3 and cross it over like that and you can see they're running the traces on the top here. and there's going to be a ground plane in a ground plane layer below that.

And of course, these are controlled impedance. uh, traces, right? And so this is called a micro strip. When it's on the top, you can actually route them on the inner layer and then it's a strip line. but then you've got to use additional layers.

I don't know how many layer board this is. Maybe we could find out some if they've annotated it properly somewhere. But yeah. anyway.

Um, yeah, you can actually run them on the inner layers as a strip line. Um, and then you could actually cross them over like that. but it's It's just not an elegant thing to do. it's just it's just not the dumb thing.

So like you could, but it's just more elegant to Simply You know, run them like that and then you've got to match the trace lengths like this. Okay, so channel one has to match the length. This is why it doesn't go straight down here like this. Okay, because this path would be shorter than this path over here.

so this is why they had to snake it around here. This is called uh, length matching and they're matching the length of the pairs like this. So the delay the student propagation delay of channel one is exactly the same as Channel two. So if you had Channel one, if you had the chip in this exact position, channel one would go over to here and Channel two will go all the way over here.

Sure, you could like add some extra snake around there to like match it. You know you could do it. Um, but it's just. it's just not very elegant as a PCB designer I'd get and they wanted me to do that again.

Really? Really? You want me to do that? Why can't we just get the user to, you know, plug into Channel one and Channel three. What's the problem? Anyway, check it out. We have a power and reset switch over here so that's interesting. They put that on the board so obviously you know you can do lots of board level uh, debug and stuff like that.

that looks fun. Um, have they got a uh JTA yeah, Is that a JTAG up there that looks like a JTAG ports and knock yourself out? They are. There's another. JTAG There's a Serial There you go if you want to get a Serial dump out of this sucker.

I won't do it in this video. Um, there's another JTAG three pin. What's going on there? Is that? No, that might be some sort of Jumper or something like that. Curiously, that one's not labeled and all the other ones are.

so yeah, don't know what's doing there anyway. power supply wise. over here, you can tell it's a power supply because, well, it's got a nice big fat chunky chip there which will have, uh, the built-in Uh, you see, there's no external mosfets there, so it's got big chunkier internal mosfets. And of course you can tell by the decoupling there as well.

There's a little uh, 3.3 volt linear uh reg there and they've got a few of these actually. There you go. It's an MP Is that an Mp52145? You can go look that up if you want. Anyway, that looks like the USB there is it? perhaps.

And our logic analyzers here. so there's probably some logic analyzer stuff on the bottom I would guess. And this is the board board interconnect which goes over to that uh, rear panel and of course that coax which goes over to the function. Jen Got some old school for a Hc-4051 analog mux.

Nice. and what is that? Anyway, there you go. It is a very interesting architecture. One capture Fpga Uh the yeah.

This Spartan Seven has that got a uh, it's I reckon that's got a processor on it. Let me check that. No, the Spartan 7 doesn't have a hard um Arm processor. it only supports like the software micro Blazer processor and stuff like that.

So there should could be running a micro Blaze core in there. but I don't know. Yeah, But of course the Zinc here. The Zinc bad boy was seeing this.

In all, tons of every modern oscilloscope uses the zinc uh, Fpga processor in it and they're pretty grunty and um, yeah, no workers. but it's interesting that one that actually makes Xylink and lattice here. So I don't know. Maybe they've got like previous um previous Design Tech that they reused on their more modern um Scopes Here that's the mark.

XO uh family. It's only got 640 lookup tables. uh 6K bits of distributor Ram Well, when I was a boy, would have killed for that. Is that a lead? I Think it is.

It's a heartbeat lead. Is it? Some oscilloscopes are we've seen I think aren't they just like the Zinc like this? ADC Straight into the Zinc because in theory that's all you need, right? Because in inside this Zinc, they're pretty powerful. It's got the Arm processor uh, the hardcore Arm process. another soft core, rubbish, hardcore arm processor that runs the operating system.

uh, runs the you know, Linux or whatever. Uh, that's this thing's working on and then it's got the Fpga fabric to do all the capture. so that's the atom there is there. I Guess they're new architecture so maybe expect new Scopes to like be based on this particular architecture and then maybe the Adcs are gonna vary which uh, feed into here.

but yeah, maybe all the new Scopes But um yeah, this is quite a significant um The increased price point compared to the rygons I Know this one has. You know it's got the function gen. It's got the logic analyzer and you know it's it's more better. but it's not like it's massively High Sample right? It's only two gig sample uh per second and uh, but well, yeah I mean the Uh four Channel Rigol.

Um HD 4 channel rival starts at 999 bucks. This one is what? 3 200 US uh dollars of course. and even the Uh Rygold 4000 HD series. or they've just changed the name of it I Think it's the Dho now instead of the HTO why they've changed it since I've done the video on that I don't know what the deal is there? Uh, differentiation Market differentiation I don't know.

Search term optimization I Don't know. Anyway, it's the Dho 4000. So yeah, it's um, significantly more pricey. So if you're looking for a budget conscious, uh, 12-bit um, entry level, um, this signal is not here.

Rygold are absolutely killing that market. There's others on the market as well I have that I Think sort of like the Nestle lesser name brand, but you know, Rygold and Signaling are now almost. You know, nipping at the heels of the top tier manufacturers. They've got some really high embitter kit and Signaling have been killing it lately.

Um, and yeah, I'm I'm very impressed by this uh design and uh, they've put a lot of effort into it and by the looks of uh we saw in there um also that it was brie badge for Lacroix uh as well and of course signal made Lacroix Scopes before. that's nothing. uh new. but Lacroix are obviously under badged this and maybe they just just yeah, um they're shooting for a hire.

Uh Price Point Market And and the alloy handle? Yes please! Manufacturers can we have alloy handles for everything? Fantastic! Anyway, enjoyed the tear down. Give it a big thumbs up As always discussed down below. Catch you next time.
