Hi in a previous video which I'll link in down below and at the end we took a look at this: Omicron Labs Bode 100 Frequency Response analyzer slash vector Network analyzer whatever you want to call it, it's brilliant. Um, but let's do a ten out of this puppy to see what's inside and also this up wideband Injection transformer as well. We're talking about five and a half thousand US dollars worth a kit and a what Is it A five hundred US dollar? Why Bad injection transformer? Worth every cent. So these things are not cheap.

They are professional bits of kit for power supply analysis, component analysis. basically anywhere from one most DC up to fifty megahertz. So this is supposed to have a 24-bit superheterodyne receiver in it and all sorts of awesome stuff. I Want to do this first? So we've got the be wit 101 Hertz to 10 megahertz wideband ejection transformer.

It's just a one-to-one transformer 600 volts cat to isolation just BNC input just the earth terminal which is it? Just be the outer case here and just banana plugs. a balanced output on this side isolated so let's take a look. Now these things are. You know, there's not many of these on the market these wideband ejection transformers because they need a really wide bandwidth I mean to go to one mega Hertz to 10 megahertz and this thing's almost rule a flat over that one Hertz to 10 megahertz range.

It's absolutely amazing performance and as far as I'm aware, there's no off-the-shelf transformer that does this. so this is no doubt gonna have some custom made a transformer in it. in this case, probably one by Art Nerd Virgins in Austria No doubt. So let's check it out.

Hopefully they haven't potted this thing, so that's my fear is that they're trying to protect their secrets cuz as far as I'm aware. but you can't really buy an off-the-shelf wideband injection transformer for less than 500 bucks. So you know you're paying paying 500 bucks for a transform which sounds like a lot. but try and get this sort of performance self and you'd spend a month of Sundays sticking around experimenting trying to get it just right where your tongue at the right angle and let's have a look.

Here we go: Oh hello, thank you I'm a colonel ABS for not putting this baby look at that. It looks very simplistic doesn't it? They've got a core in there and they've just got in. this case. Here we go.

We've just got the Twisted Pair I Don't know what's inside that is that some sort of there there silastic that under there? Not sure if we're going to be able to see in there. Is that some sort of magnetic voodoo just to take the edge off something? Or is that some sort of protection? perhaps? I'm not entirely sure. Mm-hmm Anyway, we've got a no-doubter choice: ferrite ring in there with just twit. in this case, twisted pair here and here.

Yeah, they actually look. they mix. You know they mix up the output and the input and wind them like that. I don't know if anyway.

I don't know my winding transformer terminology names. If you know what that particular technique is called, then please leave it in the comments. But there you go. That is a 500 buck wideband ejection transform.

But as I said, it is hand bound by nude virgins and it is tweaked and characterized and performance characterized to get that flat response. And as far as I'm aware, there's no off-the-shelf transformer which will meet this sort of spec. and I don't think that's actually litz wire or anything special like that. I think that's just solid core.

Correct me if I'm wrong, but that's probably just you know, a single strand, a solid core wire and sorry to break it to you, but that's not some weird-ass magnetic voodoo in there. It is a fuse and they're just soldered the wire directly onto the end cap. That's pretty how you doing what. they couldn't do an inline hold her Anyway, that looks like I'd say our ceramic fuse and these things which I thought was some magnetic foodie.

Just okay, we'll talk anyway. it is constructed with care and I like how it's on the rubber in the bottom and that just squishes or wedges between that so it's not going to flap around in the breeze in there. So there you go. If you don't think that's worth our 500 bucks then I guarantee you could call another market with a low cost wideband injection transformer.

If you could sell one for a hundred bucks, everyone would want one. And you know power supply, injection testing and stuff like that. And if you can do it and get similar performance to this, go for it. Now for this bad boy, the Bode 100, let's go again.

Made in Austria right? all my Austrian viewers. Brilliant! It's the back panel that's very nice. That's just the ground earth in thing for the entire well. It's not earthing because it's not mains earth because it's a use as a floating plug back supply input.

But it does ground the entire case so just two screws on here. it's in a beautiful case. I Love this all your ready for it. Ah, metal cans.

they're not soldered so we can lift the lid on those babies. Oh jeez, it's a bit naked isn't it? All the magics happening in the cans? Ah, we're in like Flynn out here a cyclone 4. So yeah, all the magics in the 10. but oh jeez, that's not your regular Fr4 class.

PCB that's some you know controlled dielectric Rogers special. There we go that might be able to give us some input into the type of PCB perhaps. Yeah, H4m, blah blah. that's quite a nice DC to DC converter section are all Rubicon caps down in here.

you know? I won't go into detail, but that's what you expect on the input. So what is it? Well, got 219 volt and sorry 9 to 24 volt DC So it's a wide range input nominal 10 watt. So anyway, like I don't think it used ten watts driving this thing. Then we've got some more local regulation right next to the metal can.

We've got a ten pin header there, so that's probably some sort of programming type theme. We've got duplicate circuitry up here for the next can, but we don't have that for the top can because you expect these two cans to be identical because they're both the receivers there. They should be identical wide receiver channels, you know. I'm a reared relay fan.

Boy, what do we got down in there? Is that a meter? Sweet. So that's obviously yeah, doesn't it? You can see the tracers going in I Think that's obviously designed to join the two channels together that internal the switching. so obviously it's at a non critical point where they can go outside the can. Mmm.

Some sort of filtery doodad going on in here. Some sort of multi-stage filter. We've got jumpers don't know what that is. Not a little low header, some sort of test I Doubt it's a programming hero.

Maybe Just oh yeah, do some production testing something like that. Oh, what's that? That's an analogue devices baby. and that's an 1898 51. There's our DDS a generator for our 50 megahertz waveform output.

So that's got a 10 bit DAC in it. No worries. So that'll do the business for a ride generating your test waveform. no problems.

and next to it, no, that's not an analog devices, even though it's got a D2 for five I Think that's just a like a seven for AC series two for five TTL chip. and after that, we move through this filter. II doodad section into an 88 double-oh-seven that's a high-speed amp. Basically, it's so like 600 bagel or something like that.

So yeah, that'll do the business. And there's our little crystal in there. Oh, it's teeny tot, but apparently this has a 2 ppm class reference oscillator in it, so that would be pretty schmick who'd have want to be? For the money? And the processor section, well out here, a cyclone for with some memory attached. It's not the least bit special, so I'm not going to go into details there, but looks like you know we might have a JTAG hitter up the top here somewhere.

Yeah, I don't know. there's a FTDI USB driver Me: So that's just basically our sampling you know, buffer and then just dumping it out to the USB port because there's no real processing done on this thing. It's just basically our control and data buffering and sampling stuff like that. And here's what we've come here to see.

This is our source. So this war so contained. Well, no, does it. It shunts it through to them to measure the reflective power.

Anyway, let's have a look. Come on. Yeah. Mon We're in like Flynn Ah, bunch of reed realizing not much else.

Oh, we've got yet another 1898 51 upside down so well the electrons are going to fall out. Um, why have we got a second DDS generator one inside, one outside. Hmm, could that be because I'm just speculating here that they're that they're basically running them synchronized. so that one you know this one in here is the generator right and the actual I generate itself for the source output and the other one might be so that the device under test doesn't affect the source and so that they can do the reflection measurement using this one as the phase reference.

Perhaps that's that's my first guess. Next to that, we've got an ultra precision 8086 76o special. Don't know what the top job up there is that doesn't That's just a probably that looks like a voltage reference. So down here we've got some filter II doodad going on.

Check that. and then we've got our sick. What? six Op-amps What do we got? And these are ad 81 70s. These are MUX and so I can only presume that they're muxing in different filtering there these ones up here.

Ah, 8 SS seven's again. oh no. only two of those two 8w sevens and one ah, that's just an OPA 2277 not low noise amp. So anyway, so then the drivers looks like they're the drivers for the output.

So then we got our output protection and resistors and six Reed relays. Again, they just be the same meter model I'm sure. Yep. I Wonder if they're shielded? Have to look up the exact part number on that? All right now.

let's take a look at the receiver. you can see my new camera microphone cable there. Tada. Ah, Anyway, we do have an internal shield, so this nothing in here except three reread relays, couple of our resistors, fewer passives, and that's about it.

And over here we have just a bunch of well, you know, 8p NSO's and that looks like the only thing special in here that must be our 24-bit ADC Is it or are they implementing that in the Altair a cyclone? 4. Hmm. And in case you're wondering, is there any magic on the bottom here? Well, no, it's just awesome passive. You know, Maybe a couple of driver trainees for the relay stuff like that.

But apart from that, no, there's nothing on the bottom. No man behind the curtain. Oh I Come on. Four, five and a half grand.

One of the nude virgins assembling this thing can surely clean the flux off. Okay, we've got our a D8 Double-oh-seven Again, our fast Op-amp and this one up here, the 8086 T5. that's just a another 140 make fast fit Op-amp What else? Now a DAT 170 there is a MUX Then we've gotten a ultra precision Op-amp again. Jeez, Oh Something different.

some Dg4, one nines whenever you see DG like that and the four series. you know it's some sort of like analog switch or maxi type thing. Probably an analog switch. Geez.

Well, they like those, don't they? What's that? Another 8170 down there? Another 2277. We've seen it before. It's just as an Op-amp and switch fest. Wow and more over here.

That's basically all there is to it. Geez, there won't it be something interesting Here we go: ATS 1271 there's your ADC And sure enough, that is a 24 bit ADC But it's only 105 K samples per second. So how do you get the 50 megahertz bandwidth? Well, that's where the superheterodyne receiver comes in. They actually use an intermediate frequency to get the signal in the particular sampling pass band for this analog to digital converter.

So I'm now thinking, well, look, there's nothing else in there. nothing else doing. What are those two I Say for teens, they look like glue logic or something. So I'm now thinking that this external DDS here might actually be to generate the intermediate frequency so that they can down convert and then sample the signal in the hundred And you know the hundred kilohertz bandwidth of the ADC.

Of course there's seven for Hc5, nine 5s. everyone's favorite. And it goes without saying that the other receiver channel is absolutely identical. There you go with just a bridge read, relay to was join them together so that's actually a very simplistic.

I Was expecting a lot more in there, but obviously they can get the performance out of this thing by you know, superheterodyne in the main well, at the fret, at each point of the frequency test. In each point of the frequency sweep, they just mix that down to the ADC in there the sample range at 100 kilohertz sample range of the 24-bit ADC that's how they get the performance and resolution. but of course it takes time to do that. And the other thing is I Didn't notice any directional company and happening here - actually I get the reflection for the S11 test.

So for the VNA So obviously I think yeah, maybe they're just using the second DDS generator here to keep the synchronization and then just switching it back through. And once you know, once you've got the phase, you've got that information that the source output here and a like or the load on the source output isn't going to affect. Or you know it doesn't matter that it affects that because they're generating and generating a second DDS But then I think they need one for the they also need it for the down conversion as well. So sure.

But yeah, they're obviously pulling this off with, you know, relatively. you know, just basically Ops. You know high-speed Op amps and switches, and and you know, 100 Kilohertz 24-bit IAD Seizing this thing. so that's really quite remarkable.

Hats off to Omicron So from that point of view, it's you know it's worthy of the price tag you pay for this thing. but yeah, it's not overly complex. I You know there's obviously not five an hour thousand dollars worth of you know performance magic in here. But as I said before in the review video, you're paying for the you know, the R&D the engineer in the software and everything else that goes along with that and making this happen.

So there you go. That's a rather simplistic teardown. much simpler than I was expecting. but anyway, they pull it off 0 to 50 megahertz.

VNA Plus, you know, a frequency response analyzer really is quite nice. Anyway, if you like that, please give it a big thumbs up. As always, our high-res teardown photos over on Eevblog dot-com and that's it. Discus: Catch you next time.

Bonus teardown. What's this song? I Think it's 600 bucks worth? Isn't it for this? Yeah, that's all you get. but I don't know. it's kind of okay.

But yeah, definitely done by definitely hand soldered by nude virgins for that price.
