Hi Welcome to the Eev blog and Electronics Engineering Video Blog of interest to anyone involved in Electronics Design. I'm your host Dave Jones Hi. What was that? You're curious to know what's inside this new Agilant Infin Vision 2000 series oscilloscope. Well, so Am.

I And you know what we say here on the Evev blog. Don't turn it on, take it apart. so let's crack this sucker open and see what's inside. Beauty.

Okay, we've got the back off and I'm impressed. Look at the shielding on this thing. Look at all the Pressed uh metal work. It's just quite remarkable.

And the fan. Check out. Check out the fan. It's actually.

um, that's actually a rubber. a rubber surround on that. That's why it's so quiet, see how how it see how it moves there. It's actually compliant, so it's got a little, uh, it's got vibration damping in there.

and I'm sure they've chosen a quality fan as well, but it looks excellent. Well shielded. it looks like there's a power supply um, baseboard down the bottom. Here, there's the real Uh interface power switch down the bottom there, and uh, there's the choke.

and there's the mains input. It's beautiful. And check out the Uh shielding they've got on the Uh USB connectors up here. Awesome! One other thing I Noticed the Bnc's on the back here made Bym, so they're not some one hung Low brand.

They're quality components as you'd expect from Adelin. I've taken off the shield for the Switch mode power supply and check out this Switch Mode power supply module here. It looks superbly design, designed and engineered. I Love it and the really nice high quality uh cable looms and and connectors which uh, go over to the main board in the back.

there completely uh, shielded between the main board and the uh switch mode and the baseboard uh down here as well is entirely agilant. It's got a Agilant. It's got the Agilant logo down in there. You may not be able to see it, but um, it's in there trust me and there's a fan controller down there looks beautifully l out beautifully designed so far.

I'm liking it. There's the label for the Switch Mode Supply it's from lineage. uh Power It's a universal uh 100 to 240 volt uh input of course and it looks like a lovely unit made in China of course, but uh I Think Agilant would have uh, chosen a quality supplier there for their switch mode. no doubt at all.

For and here it is in its naked. Glory That was pretty darn easy to take apart. It was designed designed really well to actually do that. I The construction quality of this thing is remarkable.

The effort that's gone into actually, uh, designing it to be. Well, I'm not going to say designed to be repairable, but you know, but designed to take it apart is just. it's just remarkable. All of the screws are essentially almost all of the screws are exactly the same.

They're identical, and it just popped apart real easy. And this is pretty much what I expected. Here's your four uh input channels. They're in there cans, of course.

Unfortunately, they're soldered onto there, so we're not going to be able to, uh, take those off. So let's look at some of the parts in a bit more detail. Let's have a look at what we've got here. We've got the four cans.

These are the Uh four channel uh, converters, obviously. and they're actually solded. Those cans are solded on there, so, uh, they would actually require quite a lot of butchering to actually get those off. Now, these are clearly the two.

uh, As6 I Was expecting one big Uh Asic which handles everything. That's what I was led to believe, especially when you power on the scope. And there's that picture of the one big wonderful ASC which does everything. Um, it's clearly got two now as you can see the uh, the tracers coming from these controlled impedance serial lines here coming from the four modules.

This is obviously the acquisition. uh Asic That's the acquisition part of it. and then it, uh, obviously you know, transfers. This one's probably the memory or something like that.

You know it's got the display memory. the uh, who knows? I Wouldn't even Hazard to guess as to the architecture used between these two devices, but they're clearly the key to the whole thing. the performance, the phenomenal update rate of this unit, and this circuitry up in the top corner here is obviously your Uh power supply section for the Asic and probably for the Uh modules as well. but the analog modules would, um, almost certainly have their their own uh local uh Power as well the ultra low noise power supply so that clearly just probably dedicated to the two A6 And for those who love to hack, there's your J tag interface right under the As6 and by far the biggest surprise I got when I opened.

this is the main processor I Had money that it would be an Intel Atom Processor running Windows C but it's not. It's an St Micro uh, Arm 926 spear uh system on chip. Now, this particular device has, um, a couple hundred thousand Uh logic gates as well. So it's got like Fpga type capability built in.

and that's clearly coupled to a Zyink Spartan 3 Fpga as well. So that's a particularly powerful combination, but not nearly as powerful as I thought it would be. I was expecting an Intel atom, not sort of a I'm not going to say bottom of the range arm 9, but um, you know, not a particularly Um. it's certainly not one of the most powerful arm processes on the market, that's for sure.

So clearly this Uh processor is not going to be doing the real heavy lifting for the display updating that's going to be in one of the Uh Asic Uh Custom Agilant Asic chips because this thing will handle um, Ethernet and and the USB ports and stuff like that. and just you know, the generic operating system stuff, the F system and all that sort of stuff and it will do the display capability. but it's um I don't think I think it's clearly not uh responsible for the real time display updating capability I think they may have offloaded that to the custom Asic that's my guess Anyway, and bingo, that looks like another JTAG interface for those who want to play around and it seems I was right with the display processing. If you have a look at the main one of the main As6 here, the What: I call the second one it.

check out all the traces heading all the way over here, through these through to the other side and guess what's on the other side Tada the display connector. So there you go. Obviously this As6 here is uh, directly, uh, responsible for the display in some aspect. So I presume the processor which is over here actually doesn't, um, talk to the display directly.

Um, it probably goes through that particular Asic which handles everything. or at least it's got part of it anyway, especially the waveform updating and waveform acquisition and display. Getting those 50,000 waveform updates per second and you just can't beat old school can you? A whole bunch of LM 324 quad op amps and this section down here because it's uh, right above the logic analyzer input is clearly the logic analyzer circuitry. and as you'll see, there are only two chips soed in there out of four.

So obviously this ERS laid out for 16 channel logic analyzer capability. but none of the 2000 series models so far released anyway have Uh 16 channel capability. So is this the 3000 Series board and it's dumbed down to take off the circuitry to get to the 2000 I Don't know cuz I haven't opened up the 3000 Series model yet. but uh, that's rather interesting.

and if you're curious to know what those logic analyzer input chips are, they're Max 9201 quad comparators. Now there's one thing with the Two Agilant Custom As6, you'll notice that there's no memory surrounding them. That's because the sample memory is built onto the die as you'd expect from an Agilant designed and manufactured oscilloscope. The Uh PCB uh, not only the component quality, but uh, the assembly quality in their Uh plant in Malaysia is first class.

It really is. It looks like the Uh components are quality, uh, components. The soldering is superb and the quality of the PCB material is excellent. I Love it! For and there's the front panel of the scope.

Once again, it came apart pretty easily. It's superbly designed. Oh my! Hats off to the guys and girls at Agilant who have crafted this thing cuz it really is beautiful. And there's the front panel PCB that handles that and that's the soft button PCB But there's nothing else there and you'll notice that it's uh, once again, Agilant branded.

it's got Agilent written all over it. and there's the display on the front and the input connectors. and that's the uh, uh, flat Flex cable which goes to the front panel. PCB Superbly engineered Absolute Precision I Love it.

And here's the bottom of the board. Really, not much to speak of at all. There's a memory uh chip up there and most of it is just, uh, localized. uh Power some filtering, some miscellaneous support circuitry stuff like that.

So yeah, nothing to write home about on the back at all. And there's the input Jacks and the back of the input circuitry as well. And you'll notice how there's uh, these highspeed differential pairs here running into this secondary. Asic Now, so if you remember before how we had the top of the board like this, the uh input channels on the top here ran into this Asic but on the bottom here, they don't.

They run into the secondary Asic here. So that secondary Asic uh does is is connected directly to the input channels as well. I Know that everyone wants to see me take these cans off the input channels, but they're solded on and I don't want to butcher it. but uh, you can see under there there's a couple of SMD devices.

There's a big Reay and that's about it. It's uh, you know you don't really have to do much for a 200 MHz front end these days. So I hope you enjoyed that. That's a tear down of the new Adelin Infin Vision 2000 series oscilloscope and it's just beautiful.

Brings the tear to the eye. What now for the big test? Will it work? Woohoo There it is. Just like a bought one. Beauty w.
