Hi welcome to another Test Equipment teardown! This is the brand spanking new, barely released silent Sdg uh, 2100 X series. I believe. This is once again the only one in the country and thanks to Charles from Trio Test and Measurement for loaning me this one. I hope I don't break it anyway.

Um, very impressive specs on this thing. 1.2 gig sample per second 120 megahertz. It comes in a 40 megahertz and I think 60 megahertz or 80 or something like that. Uh, the 40 megahertz model starts at 499 us dollars.

I think just below that in Euros. but this is the higher end model. the 120 megahertz version. I'm not sure if it's the same hardware inside and it's just software.

It's not software upgradeable I don't believe, so it could very well have a different hardware inside the thing. Hope it's not just a firmware difference. Anyway, this top-of-the-line one 899. but for the specs, Absolutely incredible.

It's got a touchscreen uh interface. I might be out you've seen it in a previous video. a brief mention of it. Dual channel Arb capability uh 20 volts peak to peak output, 80 db dynamic range claimed and that 16-bit 16-bit converter.

So they reckon we'll take a look, see what converter they're using. Um Dac? that is. Uh, 1.2 gig samples per second. You know what we say here on the Ev blog.

Don't turn it on, take it apart and it looks and feels decent quality. Decent tilting. bail on the thing, by the way. Um, a typical, uh, sort of.

They're pretty stiff rubber uh surrounds. Don't mind them. Anyway, it means that you can drop the damn thing onto the floor and it's you're not gonna bust your knob. Nothing worse than busting your knob, let me tell you.

And uh, on the back here. Once again, these cheap ass Qc's pasty because I don't know. It doesn't instill a lot of confidence. Anyway, comes standard with Ethernet as most things do these days.

Usb looks like it has external frequency counter, auxiliary in out, not sure what the auxiliaries are doing, probably some sort of trigger out in or out, and a 10 megahertz reference. if you've got a lab standard, that's very nice and it should very easily slide off. We've got some torque screws in here. these would be metal threaded inserts.

no worries at all. And the thing where main thing we're interested in is of course the dac. What deck they're using in what 16-bit dac they're using for the claimed um, 1.2 gig sample per second. so it looks like uh, maybe screw on the bottom the front.

we don't have to take off. Um, there's one screw on the back here if we take that off. Um, it should just slide off. And I had to take the tilting bail as well off.

but no worries there whatsoever. Once again, you know, siglin don't do metal work that well. Cigalette metal work is never impressive, but uh yeah, no, there's no rust. um but yeah, it just seems like you know, rough and ready doesn't instill a lot of confidence, but singlet products are built down to a price.

You get a real big bang for your buck. And ta-da look inside. Wow. that's nice and clean.

Well laid out. I like that that really is rather clean. What they've got is, uh, once again. First thing I always notice about these sort of things.

Um, you know, airflow and stuff like that. Got a fan on the side? It's not particularly loud blowing out this side, sucking in. They've got a grill in there. they've got there.

You go between the power supply and just a big big cut out on the other side. So airflow they've you know. Yeah, it's not the best thing I've seen, but it's probably adequate. Not not sure why you'd need a fan in something like this.

How many watts does it take? I might have to. actually, uh, power the thing up and have a look. There you go. Almost 18 watts for this thing.

I mean, how many, uh, you know, 31 Va power factors? Not that, uh, terrific. at 0.56 you know, Why do you need like 18 watts to run a you know, a Sig Gen I? Ah, but yes, it has a real clunk and power switch on it so it doesn't draw anything when you switch it off. Beauty. But anyhow, it is very neat and tidy inside.

and I like the, uh, there's the main Fpga down there by the looks of it. and like the fan is like sucking the air straight across that heatsink. Beautiful. Um, they're blocking the vents up here though, with the, uh, all the ribbon cables there.

That's a bit meh. but you know it doesn't matter because we're not talking about much power at all. Anyway, I'm not sure why they've got the two separate uh boards here. I don't think they're opto-isolated We'll have a good look down there, but maybe they've got like a generic uh, it looks like a generic processor board that maybe they use for different uh, instruments and things like that.

And of course that you've got your main um Dac and you know your Dac will be down. That's probably the Dac right there, I'd be saying. and your output relays and all your output uh, amps and stuff like that. So that's our whole analog board, so I don't know.

generic. uh, probably got a Jtag interface down there by the looks of it. Um, to program the main processor. So let's take a look at some detail.

but power supply in here looks quite neat. We'll have a look at that first. that power supply is not too uh shabby at all. They've got a the Earth cable coming up here, heat shrunk on there.

I would have preferred to, uh, see that. you know I've just got the spade. like. Would have preferred to see a proper nut and washer in her face, but nothing doing.

Um, they've got a protected glass shoes down there, like a protective cover over it. Looks like maybe mob protection down there is it. can't quite see. Anyway, they put some silastic on that.

Nice big mains wiring going over here to the front panel switch over there. I like that they ran out of room to obviously route that on the board and to keep their mains. um, voltage clearance and stuff like that. So there's jumping a cable over there that's even got heat shrink on it.

Gee, you know they've gone to a bit of trouble to tie them together there. Um, all the output caps have been selected down and it's just, uh, rather neat and tidy. It's got all the uh, requisite stuff you'd expect, you know. main input filter cap ruby Con: Thank you very much.

They haven't skimped there. very nice and it looks like almost all of the output caps are Rubicon. thank you very much. We've got a proper isolation slot down there routed out around the mains connector front panel switch because you know this is the his the 240 volt mains.

And here's the output secondary side. So yeah, you've got to have that isolation slot, but that is a rather neat and tidy power supply. Looks like it's using quality parts. It's got all the requisite stuff.

um, yes, so thumbs up to that and the main processor down there. I don't think I've seen one of these puppies before. This is a Texas Instruments Am 33 52. It's part of the Satara family process.

I don't know what Satara means, just some wank word they've pulled out of their backside. Anyway, it's a basically an Arm Cortex A8. It's got some image processing built in it, Linux, and Android those you know, high-end operating systems. got Ethernet, Mac built in and all the requisite Um stuff.

and this one is the Zcz, which is the Uh can go from well, I think 60. on the end. there is the 600 megahertz model, but uh, it can go up to one gig. So pretty speedy processor.

Then we've got our firmware, flash memory, and just some Sd ram surrounding that. Nothing much doing on there at all. It's all pretty boring. And hello micro Sd card socket down there by the looks of it that allows them to, uh, you know, boot stuff on here, probably program it, do some development and stuff like that, but it's not.

Well, there's nothing in there. so they obviously you know they're paid for that connector they've put it on in production, so obviously they're using it. If they didn't intend to use it during the production processing somehow, then you know you wouldn't pay the money to actually populate it. And I presume.

we've got a Jtag interface there, and this little uh, five pin job. Could that be some sort of uh, serial monitor interface? perhaps? I know you're saying Dave? show us the Dac. Well, here it is. And yes, they're not lying.

It's a uh Tx stack from uh. analog devices. Uh, it's the 1891 22 and it does the business. As it says on the front, this is a dual channel 16 bit dac.

High dynamic range Uh. 1.2 gig samples per second. This puppy goes for about well on digikey at least goes for 60 bucks in 2000 quantities. It's not a cheap chip that you are designing willy nilly, and in terms of power consumption, this thing takes about one and a half watts on its own, operating at the full one gig sample per second.

So, and it really is a very professional high-end dac. and I'll link in the data sheet of course for all you dak aficionados and you can drool over the specs for yourself. But yep, they're not lying. It does the business and looks like we've got some anti-aliasing output filters next to it.

That's uh, that's what you'd expect. They've got that all. Uh, all discrete. You can see the little blue parts.

There are the inductors. You should be able to see the windings on those, perhaps. And yeah, there, that's a complex network. if there ever was one.

And of course, as you'd expect, there's two of those. so two identical networks. A couple of missing parts there. I'm not sure what the business is there.

There we go. So where's Wally and the accuracy and stability is going to depend upon that puppy. Um, I don't know. E who's who's that manufacturer of that 10 Megahertz reference oscillator? But as you saw on the back, if you've got a much better, uh Lab Frequency reference Standard 10 Megahertz Reference standard, plug it in and use that for this high-end instrument, because really, this is quite a high spec unit and you know, if you want to get the performance out of it, probably worthwhile sticking in an external reference.

And they've got decent relay switching on the output as well. Nec, thank you very much. No one hung low rubbish in here. And there's our output amplifiers.

Uh, two of them there, mounted on a little, uh, thermal pad on the back by the looks of it. Um, these are Texas Instruments Ths 30 95 high bandwidth current feedback operational amplifiers And you can see the 49.9 ohm output resistors there on the other side, And these are expected over 200 megahertz bandwidth. So yeah, um, presumably whether or not they use these in the 40 Megahertz model or whether they use lower spec parts, I don't know. We'll have to get somebody else to do a tear down of the 40 Megahertz model, and although both connectors are down here, they've got two of those per channel because it's all duplicated all the relays.

Everything else there we go. We've got another two output amplifiers up there, so it's Got to go a fair way to the output connector. and although I can't get that heatsink off because it uses thermal adhesive and tell you what Fpga they're using in there unless I hook up to the J tag and try and get the Id and stuff like that, we can tell maybe by this puppy here, which is the En 23 42 4 amp buck converter. This is, uh, recommended by Altera, so this is like Altera have a application note on this: how to power their uh Altera Fpgas with this puppy.

So um, pro. Almost certainly they're gonna have an Altera Fpga in there. Which one there Does it really matter? Anyway, that's just chewing most of the power in this thing. But look at the pin pitch on that bastard, would you look at it? That is evil and that's a 0.5 millimeter pin pitch.

But thankfully almost most of those pins are not used. they're just not connected or they're grouped together. And this package is really interesting here. Here's some data for it's actually got a really big ground power uh, pads on the bottom.

Around about this location here you can see it's a really thick package so I'm not sure what the business is there with, uh, the dye and that inside of it, but it's very interesting. Here's a photo of the thing and uh, some details you can see. There's a huge ground pad on the bottom and they give you footprint recommendations. There's thermal pads and everything, and it's a rather obscure package.

One you're definitely not going to get the footprint for in any Cad package on the planet. So yeah, you know you would have to, uh, roll this one your own unless they specifically had all the uh, in period um, parts already. Uh, done for you. But yeah, it's painting from a Pcb layout point of view.

Do I have to use that package? really? Ah, Anyway, breaks the monotony. Anyway, just this, uh, converter chip alone. Uh, more than 10 bucks in. you know, a couple of hundred quantities.

So it's not a cheap puppy either. You know, we've got lots of linear regs all around here. There we go. You know they're not switching converters by the look by the lack of inductors around there.

and it's common to get those five pin packages like that for various adjustable linear regs. But yeah, so lots of power supply. That's the problem. When you start talking Fpgas like this and other logic and stuff like that, you know you need to get all these different rails.

So they're going to have this is 20 volts peak to peak. so they're probably going to have plus minus 12 or plus minus 15 volt rails here for the analog section. They're going to want to keep that quiet so that's all going to be separate. They'd have a separate, you know, 5 or 3.3 volt digital.

Then they'll have the various uh core voltages. I mean, obviously the the main switch we looked at down here is actually doing the main core. Uh, for the Fpga main core voltage there. But yeah, I mean you just need lots of power supply stuff.

Just look at the board. I mean, you know one third of it is bloody Power supplies. right next to the anti-aliasing filter. There's a little puppy there, the H1k513 and I don't know what that sucker is obvious, is that some sort of uh, diff amp.

And then on top of that, we've got ourselves a Texas Instruments Opa 695. that's a bit of a beast. that's a ultra high band with current feedback Op-amp and it's got like, you know, the 1.2 gig, uh, bandwidth at a gain of Uh two. So pretty smicky device.

and once again, these two chips are duplicated on the other side right down there. If my damn thing will focus there we go. So clearly what's going on here with the one channel? Okay, we've got our Dac here and this is a current output dac by the way. So we've got ourselves A and B massive anti-aliasing passive network here and this has got to be a current to voltage amplifier.

And then we've got our real high bandwidth voltage amplifier here, which we looked at and then probably. I haven't looked at these two, but I'm guessing. um, maybe some Dc offset stuff happening around here. And then there's our two output drivers there.

So that's uh, duplicated exactly down on the second channel as well. Yep, I just checked. Uh, these two puppies here are 8085 one, two ways. They're just, uh, you know, some sort of like almost jelly bean, uh, low noise Jfet Op amps.

So as I suspected, most likely doing uh, Dc offset functionality. So there you have it. Not much else to it. That's a look inside the new Siegeland Sds 2000 X series oscilloscope.

So thanks Charles at Uh. Trio Test and Measurement for uh, loaning this one, letting us have a look. and uh, starting at uh, 499 bucks for the specs. Jeez, it looks pretty schmick.

Let me tell you, it's built fairly well. I've got no issues with that at all. It looks like it'll do the business, so as always, if you like that, please give it a big thumbs up. And hopefully I'll do some more stuff with this before I have to send back.

It's only a demo, loner unit and well, hopefully, um, I'll probably compare it with the existing Siglet one I've got and the Rigol one as well. hopefully. So if you want to discuss it, forum link down below. Blog, Youtube comments, all that sort of jazz, follow me on Twitter, blah blah blah.

Support me on Patreon. Thank you to all my uh, Patreon and other uh, financial supporters. It's what keeps the blog going. and yeah, by my merch and you know all that sort of stuff.

Or I don't know. if you don't like any of that, don't do any of that. That's fine too. Thanks for watching Catch you next time you.
