Hi, it's world exclusive Tear down time. We've got the brand new Tektronix 2 series oscilloscope released today. Links are down below and this one what is a qualification build so there might be slight differences with the final production version. I haven't heard, I don't think so, but just be aware of that.

This one was actually hand carried over here by Tektronix and I'll link up here and down below. My initial reaction video to this and also a talk with Uh. Andy Ted about the design of this thing. We talked for about 40 minutes just before he had to hop on a plane about the Uh design and build of this thing.

So let's check it out. Isn't that just gorgeous? I'd love to stand on this thing. It's just fantastic. And yes, we will tear down the Uh optional battery pack for this thing as well.

So let's get rid of the stand and let's get into it. and the cover for the battery pack. here. this actually fits into a slot on the Uh battery pack.

so um, yeah, it's just off. We got the Visa mounts. uh, of course and these are the battery pack uh clip ones as well, but I guess you could use those for mounting if you really wanted to. But you know these are standard Visa mounts.

So absolutely brilliant. So you can see the tablet like form factor of this thing even though it's not actually a tablet. uh, scope. It's more of a new concept.

Thin portable bench scope uh, which you can you know mount on various Visa mounts and then you can convert it into a portable scope if you want using the external battery pack, so it looks like it's going to be really easy to get into. We've just got some Torx screws around here and they did say that one of their design aspects of this thing is that it is all single board construction. So and that may have led to design decisions like the uh, lack of the tech tpi uh probe interface here because you were like most likely would have required a second uh you know board in there just for the Uh connections, uh for the active Uh probes and also why they went with the membrane keypad instead of uh your regular buttons which then have to be deeper and then probably on a secondary board. But let's find out by taking it apart and looks like these are all self tappers into plastic so that's a bit disappointing.

I expected some metal threaded inserts there. come on. I mean, you know this is not bottom of the barrel pricing. Although yeah for tech it is.

Is it just going to lift off? Dunno, have I forgotten any? Is there another one in the middle? What's going on? Uh, is there a sneaky bugger under there? There's four sneaky buggers under there. Look at that. Is that like a big heatsink under there or something. It just seems weird and they're offset from the center so it's almost as if it's like an operational Pcb heatsink thing.

instead of like being an external designer. it's driven by the Pcb layout in there. That'd be my guess. So this is where the Pcb designer might have actually, uh, driven the or had to feedback to the mechanical case designers what they actually wanted.

Um, so anyway, there we go. there. We go. Okay, ready.

But no, I'm wrong. What? No, I'm not wrong actually. Um, I just expected to see a big, uh, like metal work under here, but you can see that the screws have gone into. you can see that all the bypass caps in there and all those uh vias.

those tiny little vias that of course will be the main Fpga under there. Could be the acquisition. No, the acquisition engine's probably down here near the front end like this. But there you go.

That is. Um, an entire single board construction isn't? That isn't that neat and groovy. And it's actually, um, smaller than this whole thing. because I'm sure one of the uh complaints will be this thing.

Or why do I need an external battery pack? Um, that was my one of my original thoughts as well. Um, what's not only for a capacity reason? I mean this thing is, you know it is relatively thin, but there are of course tablet oscilloscopes on the market that actually have internal batteries. and they actually work as tablet oscilloscopes. Because by the time you add the battery pack to this thing, it is quite thick.

It's no longer sort of a tablet-y uh, form factor. So oh, there you go. I'm gonna pin stick it up there. What's that doing? Ah, we've got another pin over here as well.

And by the way, that is not actually connected through to any sort of uh, you know, shielding on the back. There's no nickel screen in, um, it. This doesn't look, uh, you know, conductive or or screened at all the back plastic on that. so that's interesting.

Um, but of course you've got the back side of the board, not the front side, but from an Emc point of view. That's just rather interesting isn't it? But we do have uh, the shield on the front end though. but that's a that's a very narrow front end. Wow.

And you can see this uh button side here. This is where all the membrane buttons are. You can see that if they use the one Pcb then they would have that You couldn't have any components on there at all. You would have to like.

All the circuitry would have to be on this part of the board and you'd have to leave. at least on the uh top side. Anyway, you'd have to leave. You'd have to mount all this on the bottom.

so there's obviously a whole bunch of chips down here. This is the logic analyzer inputs, all the logic analyzer stuff you could have mounted it on the back side so they could have. Maybe they could have done it. I don't know.

I'd have to actually get the Pcb files and actually you know, play around with and spend a lot of time playing around with this thing from my uh, you know, a layout engineer uh, point of view. but you can see that the Usbs are on the front, but even then, like yeah, you would have had to clear out the entire front part of this Pcb here. uh to get your buttons just on the uh front on the single board if you're you know was so desperate to get this as a single board, uh, construction then which they obviously were. I've been told it is single board and it looks like it looks like they don't have anything else under it.

so we'll take it all out and have a squiz of course. But um, yeah. Anyway, this is interesting. Here's our big grounding point over here.

because here's our big. You know, they're serious about their mains Earth connection and it gives you a warning when you boot the thing up. Um, I don't don't know if you can disable. it's rather annoying.

actually. please ensure the Earth terminal is connected blah blah blah blah blah. But anyway, they've gone to town on that look at that that's absolutely, uh, beautiful. It's all heat shrunk down there.

but this was one of my, uh, original, uh things that I thought about and you'll see this in my other. My reaction, uh, video I believe and like, why does it have to be on the side? Why couldn't you've had it on the back? There are some scenarios where having the power connector on the side like this is beneficial, but there's other ones where you don't want it sticking out the side, you want it coming out the back, or you want at least a right angle connector. But it's not a right angle connector. it's actually the one supplied is, um, just an inline jobby like that.

But I guess the good news about that is if you bugger up your connector, you can actually replace it. So I do hope they actually sell this, um, as a replacement part. um, and or make it, you know, obviously. um, easily serviceable.

So yeah, so that is one of the things I wanted to check like. I would have been disappointed if this was a right angle, uh, Pcb mount. uh thing, because like you know, like a big part of this, especially if you're doing it every day. the uh, fatigue of actually, uh, you know, actually connecting this connector in and out.

It could not wear out over time. Of course that is a distinct possibility, but I did notice it was actually uh, screwed in there like that, so no worries. But uh, yeah, they've got. Actually, it's quite a significant amount of space around here and up the top as well.

So I guess in theory you know you could have shoved some like 18 650s or or something up there for those who are complaining about. yeah, why doesn't have built-in batteries? Well, you know, technically it would have been possible, but this thing's like 50-odd watts. I think the brick is about 60 watts or so. uh, maximum.

I haven't measured the actual power draw, but yeah, you're not going to get much uh usage out of this if you just put some 18 650s along here or something like that. You know you could have maybe had like a plastic cover on top of this and then a thin layer of pouch cells or something like that. But then the design gets a bit tricky and then you've got to have you know, then you can't get the screws through to do this. uh, sort of stuff.

And yeah, technically I'm a bit disappointed with uh this because these Visa mounts are probably expected. like a big bit of metal work in here, but it's not. It's just the uh, back, plastic, uh, backing, and uh, no metal threaded inserts for these screws. But you know, this thing doesn't weigh, you know, a heck of a lot just on its own like this.

So putting it on a Visa arm, it's not a huge amount of stress, this plastic's got to take it. It's just I just expected like a metal bracket in there or something. but you know you want to get the weight down. So yeah, fair enough and attention to detail here by the Pcb designer: Backside flip latch like this.

Um, you can almost see this coming about because the Pcb designer went, oh yeah, people are going to come a gutter with this one thinking that, oh, you know we're going to flip it like this or we're going to pull it out or whatever. But no, it's a backside flippity-doo-dah like that. So really appreciate that as a Pcb designer. and the shield for the front end, it just start lifts up.

They've got a whole bunch of uh clips in here, but it just clips off and interestingly, they really didn't need these raised bumps on here. I guess they might have uh changed. I guess that was uh designed and thought about at the time when they didn't know exactly what uh, you know, front panel B and C connector that they were going to use, but you can see that it's not raised there at all. It's the same as the uh ground.

The center pin is the same as the surrounding pins there, so it doesn't really protrude at all. So maybe they designed that chain, made a change to that, um, you know, a bomb change to that uh Bnc connector later and it doesn't have a big center pin sticking out, which is what you'd need these things for. and they do come out quite a long way. But yeah, they're actually not needed.

This is going to be a very simplistic front end. In fact, I haven't seen one like a 500 meg front end this small because it is software bandwidth. uh, definable of course. So anywhere from 70 megahertz up to 500 meg.

We've got a relay here and we've got our input resistor here, and a couple of you know, passive jobbies and stuff like that. But yeah, it looks like this. It's not going to probably not going to be a huge amount on the other side, because, well, it only goes covers this little small section here. It's really remarkable, but you know that's the advancement in technology over the years.

I'd love to compare this with, like the original Mso 2000. Unfortunately, I used to have one of those donkeys years ago, but I don't anymore. so unfortunately maybe I can see some, get some tear down photos or something. but I don't think it went to 500 meg.

But yeah, ah, these newfangled front ends. So from a product design point of view, I can really appreciate wanting to have this all on one board and not have to dick around and have board interconnects and everything else. Uh, to lower the price and you can see how that decision might have driven, uh, some of the design decisions. I mean, once we get this out, you know we might see Okay, well, maybe they didn't have room for the tech interface because that will be one of the big complaints about this as well.

All the other series had them and the original Mso2000 which this one is actually replacing, uh, completely. I don't believe they're selling it after this is actually released. Um, well as of today and then I'm releasing this video then. and yeah it it had tech Tpi interface so that will be a big complaint.

but a lot of those decisions will be driven from. You know, they made the call. We want this single board construction so therefore it's going to drive these design decisions like the buttons and the Tpi interface and other things. And I always appreciate the Pcb and mechanical teams working together.

You can see that they went to the effort to just do a little rounded out bit there. um just to allow these cables to come out even though they didn't need to. Um, they've just gone to the effort there. Nice.

So from a servicing point of view, if they are going to actually, um, service these things, then yeah. like you've just got a couple of connectors around the outside like this. It's very clean. Uh, looks like we've got the backlight.

uh, connectors? or is that uh, touch or whatever. Um, I don't know. Um, but yeah, we've got just a couple of connectors around the outside like this and nice attention to detail about how to get them off. And I think once all these screws come out, it's just going to pop open and it's going to be a very simplistic and clean design.

And I really appreciate that. So it looks like under here we are actually going to get our metal bracket because this, I can see it bend under and I can see some metal under there. There's another one poking up here and that'll hold the screen in so that's actually acting uh as because it's dissipating a fair bit of power. and it's got the passive cooling vents on here like this, um which aren't anywhere near the metal, but you know it doesn't really matter and it looks like that.

Yeah, they're gonna get away with one Pcb. so maybe that they got so sick of, uh, like maybe the complexity of existing builds in like the Mso 2000 or something that they went right. We're going ultra simplistic. one board for everything and it looks like possibly one big metal bracket for everything as well which does the heat sinking and does the mounting of the screen and the pressure and all sorts of stuff.

So I think we're gonna see this, um, clean, simple design manifest itself in the rest of this and this is a stark contrast to uh, other scope designs were torn apart which have then a back metal case and a front middle case. and then they've got a bit of metal work for here and there and everywhere. So now I'm taking out all the ones labeled Pt. But there's two others here labeled M3.

so I'm going to assume that that is the heatsink in there. so I'm not going to take out those. I'm just going to take out the Pt's around here and I think our whole board and front panel assembly should lift out. So here we go.

I've got all the Pt screws out and will this sucker lift out? No, No. Have I missed one? Or I might have to take out these M3s. And they're numbered one and two. but there's no B and C rings.

So um, yeah, come on. And these are metal threaded inserts. As I suspected, because I reckon there's a heat sink under that bad boy. Let's try it again, shall we? No, I still can't lift it.

Oh silly me, I've got to undo this. and the whole bracket's going to come out. Aha. that actually clips out of the front like that.

So yep, Yep, Yep, there it is. That's kind of obvious when you think about it. I've put those uh, screws back there. I completely forgot my knobs.

Always remember your knobs. very important. so this bad boy should now just lift off. That's the.

that's the theory. Anyway, Tada, there you go. Beautiful. Look at that.

Yep, one big metal bracket. I was right and that's all she wrote. And oh, interestingly, there's our fans. Okay, we've got three, lots of Um.

Rf connecting sponge here which connect down to the metal backing plate of your Lcd, which is in there like that. So we've got two blower fans in here and they blow out the top. Aha, so that explains what this top cavity here is for. It's for ventilations, so that's just to get the air out.

That makes sense now. Yeah, no worries. So these two metal pins are stuck into the plastic standoff like that. and they do actually go into the back case.

So they're like alignment pins. although that one's that one's uh, not exactly round. So yeah, but that uh, helps when you put in the back case on, I guess. but you know these, it all fall into place.

Oh, you've got to rub those. I'm not sure why they went to that, uh, effort there for that alignment, but obviously someone in production went, hey, you know it'd be really nice if we had these for alignment when we're actually putting the things down. Or maybe they've got a lot extra alignment pins for? no, it wouldn't be for test fixture after you've put the board in. Our Bncs do actually have the locking nuts look at that, that's interesting and then they've got, um, yeah, like a metal standoff thing that's that's fascinating, isn't it? And they're sold it down in the Pcb, so that gets extra rigidity.

So huge bonus points for the mechanical, uh design of that which takes some, um, stress off the Pcbs. these were just, you know, sticking right out of the Pcb. It would have been a bit how you're doing, but no, they've gone to that effort. and they've got these cutouts in here like this with these little prongs which then just hold the nut in place.

So um, hats off to the mechanical designer that came up with that. I don't think I've seen that before and that just, um, like is like an anti-vibration thing to stop the nut coming off. That's rather neat, although it's only friction on the top surface of that flat nut. It's not rigid digi or anything.

but geez, that's pretty neat, isn't it? And sure enough, there's your two metal threaded insert standoffs M1 and M2. Sure enough, yeah, that just extends down. They've got this, uh, welded onto here on the bottom side, so they didn't actually stamp that out. I would have expected them to sort of like stamp it out like they're doing down here.

They've obviously got another heatsink down here. Not as important as this Jolly. But yeah, they've like they've stabbed that in, like pressed it in. They haven't done the same here so, but obviously this would be a lower thermal resistance than what they're doing over here.

But that's interesting. So that's your main Fpga. There's your memories, so let me get all that off. But yeah, that's neat, huh? An extra direct ah, shielding going straight over like that.

They've put these as press contacts going down this and once it's all screwed into place, it's going to make some extra Rfi contact over here. And sure enough, you take off these two screws here and it drops away. and we've got the entire Pcb. And yeah, you can see how these are welded here.

and it's a thicker Uh plate than just the thinner backing plate we've got here. so this would have a much lower thermal resistance. They did this. Um, they would have determined that yeah, they needed a lower thermal resistance to the Uh heatsink back plate in here than they did with uh, this one down here.

So let's check it out. Tada, we're in. Look at this. No surprises for finding the Xylink Zinc uh, Fpga here.

We'll have a look at that in a minute. But obviously. uh, we've got two Adc's here. These are off-the-shelf national Semiconductor jobbies.

We've got our memory here. now. This thing only has 10 meg of memory. I don't know if that's a limitation.

We have to look up the part number of these, see what the total memory is here. Then we'd have our boot memory for the Fpga do we? And then we've got an application processor down here. we'll have a squeeze out. and they're the two ones that they're heatsinking.

Not bother. Uh, heatsinking the Adcs here. So just off the shelf. Um, very little in the way of uh, custom tech logic.

Although I do believe there's a custom tech front-end logic under here. Unfortunately, this is just evil. Um, this plate here doubles as the shielded and that's all soldered down. So to get in there, I'm going to have to de-solder this thick heavy plate here and hope I don't damage a front end.

Better do it on Channel Four or something, just in case I goof it. So would it have been possible to, uh, move all these parts from here and have a real button interface? Well, you know. Look, I mean, there's plenty of, uh, room left around here to shuffle all these uh, components up and stuff like that. I know you have to keep your routing short from your front end, but certainly that could have been shuffled over.

But then the problem is, you've dictated that you've got your connectors on this side of the board so you, oh no, you could still drop them down and then, yeah, nah, not really like you're really like you could have. I can understand why they've gone for the membrane keyboard. Now this is interesting. They've got like two rings in here with annotation.

must cover and may cover. So obviously this is the real-time clock and this is the Uh battery. So this is the positive terminal of the battery on the back side of that and so obviously they don't want this shorting out to the metal work. So that's just a note from the uh designer that you know.

Look, make sure this terminal doesn't get shorted to anything so. but there's no like a, you know, tape or plastic sheet or anything like that to stop it shielding. They're just, you know, a note at the design stage. Um, just make sure you know it's not close and then they've got the same note down in here.

This is, uh, the battery terminals and that the battery pack pack plugs into. So yeah, you definitely don't want that. But once again, like, there's no, um, you know, plastic insulation. So they just determined that the standoff distance is fine.

And yeah, that's fine and dandy. But this is the kind of detail that you'd put on your Pcb just to, uh, aid the other teams like the mechanical designers who are designing the metalwork, backing plate and stuff like that and the uh, you know, production team who are figuring out how this thing is going to be assembled for an optimal cost and tested and all that sort of jazz. And you know, just these notes help uh to make sure that you know you don't goof up something down further down the chain that was out of the control of the Pcb designers. So that's a just a nice little bit of uh, cross design team engineering there.

Well, I'm getting there trying to extract this from front end can, but uh, it ain't pretty. you're not. I think I got it. I don't think I lifted any pads.

Oh winner winner chicken dinner. And there's the single chip custom Asic solution for the front end. Like single chip, it's amazing. 500 megahertz bandwidth.

all in that one custom Ac chip. The Tech 026. Now this is actually used in, Believe it or not, the um, what is it? the 500 Tech Tbs 2000 series and I believe it's also used in the Uh Tech 3 series as well. although I haven't done a tear down of that but I believe it is at but the higher end tech ones have a what much because they've got higher bandwidth, they've got a much, uh, newer Asic in there.

It's your typical Uh 500 Meg band with variable gain amp now of course. Uh, the front end of this of course is software licensable upgradeable from 70 megahertz to 500 megahertz. and yeah, I know all of them do it. I don't actually know though, if it's actually done internally at the front end or whether or not it's done after the Um sampling.

But anyway, single chip solution. Uh, there is no 75 ohm input impedance. Um, on this. So we've just got that solid state relay that we saw on the other side and basically, um, it's just a like a variable gain amplifier and attenuator on the front end.

so it's just a differential output here. Looks like it goes through an anti-aliasing filter here and a match length differential pair. They match it to the other lengths over here. That's why it's got a wiggle wiggle wiggle the air in there to make sure.

Uh, that the skew time in between channels is the same and it goes up to our off-the-shelf national instruments Adc and Bob's your uncle. Um, there's not much to it. Modern 500mx scope. Geez.

when I was a boy. All right. We haven't done a 4k screen capture in a while. So let's have a look at some high-res photos available on my Eev blog flickr account linked in down below.

It's where I always put my tear down photos if you want to see the high-res stuff, but this is high-res and I can zoom in. as we saw before, there's not much on the bottom side here. You know there's a few chippies up here. Of course there's all the passive bypassing and stuff like that.

We've got some regulator action going on here. You can tell that's a regulator by the caps around there, like that. You know, like transistor array down here doing something. and we've got some output fusing stuff down here.

This is for the generator down here. so the generator is output fuse that doesn't look like a resettable jobby. So um, it doesn't mean it's going to blow if you short the output. I think it's more designed if you feed something back in, you know this is like these will find its way to uh, student labs.

And yeah, that sort of thing happens. Anyway, that'd be like the 50 ohm output impedance there. Uh, you know, probably got some driver stuff here. I don't know.

Anyway, this is the Um. Asic. They've actually got a custom generator asic and this is the back side of the Asic, which we'll have a look at and well, you know there's not a huge amount. Of course, we saw the bottom of the analog front end here.

We've got our relay here. That's our solid state relay. None of that mechanical rubbish. so no clunk for all you clunk fanboys.

Um, and that's the Ac bypass cap. So that's what that relay obviously does. It does your Ac, Dc, uh, bypassing, and everything else is done. Um, in chip, all your attenuation, all your uh, amplification, everything else.

they do conveniently have like test points here. three volts and stuff like that. So that's nice. That looks like our touch interface there.

And here's our power input from the uh, Psi connector here. and um, that's some protection. little protection array or something, perhaps. Then we've got an interface here with, um, no connections on this bottom side, so I don't know.

Um, they might be some sort of test interface. I don't think they're Jtag because Jtags over here. So you got the chippies up there don't know what they're doing. I couldn't be bothered.

I'm not going to go into a huge amount of detail on the minor stuff, we'll just look at the interesting stuff. Um, that is our battery connection interface with our alignment pin there. Nice jobby and this would all be part of our front panel membrane keypad interface here. So they're just doing some matrix switching or something there, perhaps.

um, and some protection stuff as well. This is our digital input here. Um, I've just got bypass in here, so that's pretty much all she wrote like for the bottom side. So let's go to the top side and you can see why they really wanted to put it on all on one board.

It is very neat. Of course, everything is the xylink zinc here. This is an ultra scale jobby. We'll take a look at the data sheet in a minute, but interestingly, you'll notice that, uh, it's actually, um, siliconed down and so is the Asic for the Uh signal generator.

this is the Uh Adg395c and that's their custom Asic. uh, for those, their 50 megahertz arbitrary waveform generator. So it pretty much does everything in here. And there's the Sig Gen out there.

and okay, is that a relay there? Oh, look at that shielded relay too. And this most likely also handles the pattern generator output here. It's not a hugely complex pattern generator, but it's almost certainly in there surely. And the probe compensation output here.

Although we've got some separate chips here for pro compensation, so I don't know. Haven't checked the features. Maybe it just does like you know, one kilohertz output or whatever. and I checked this again.

It's not silicon. it's actually, um, hot snot, uh, glue or some sort of hot snotty type thing. And um, this would have been added after they, uh, reflowed the chip because you want the chip floating when it reflows so that the surface tension of all the balls just pulls it, um, exactly into place. So they would have added this for, uh, mechanical strength afterwards, even for uh, you know, thermal cycling of the chip because this one and the other one are the two that have the heating.

That will just help take the stress off the solder boards. It'll transfer the stress from the metal package to the Pcb. That's the plan. Anyway, how effective that is? I don't know.

Has anyone got data on that? Let us know. So this is where all the magic happens. The Xylink Zinc Ultra scale plus um, part number there and this is 935 Yankee Bucks one-off on Melsa, so it's pretty beasty. Um, of course they're not paying that.

They get them involved significant volume, but still, they'd be paying you know, hundreds of dollars each? uh for this chip. and uh, we won't go into a huge amount of detail, but let's have a look what it's got. So it's got an Arm Cortex A53 and that's what they're using for the applications processor on this thing. Um, it's a quad core or dual core.

Up to 1.5 gig as well for the core, so it's pretty schmicky. It's got a media processing engine and a floating point unit don't wear an accelerator coherency port and all the application uh, memory will actually be inside of here as well. And it's also got a separate real-time processing unit rpu as well. And this is the block diagram that Tektronix gave me.

It doesn't tell a huge amount here, but basically, um, yeah, every Fpga is. So they do mention the Rpu here, the real-time processing unit. so presumably they use that for. I don't like the screen updating or something like that, but they use the A53 core.

It looks like they might use two of them. Um, and then we've got the e, um, Mmc, uh, memory. have a look in a second. Um, we've actually got a Ddr4 uh, memory on this sucker.

So uh, but yeah, like that's maybe the external memory controller down here. Maybe they haven't shown it. But basically the digital input comes straight through comparators into the Fpga so that's going into the fabric. That all makes sense.

It says there's a display um, engine in there, which is the one we looked at and it does everything else it does. The 1280x800 display does this touch screen outputs to the wavegen. it does. It's all in that one chip.

There's some more detail: Mali 400 base Gpu, everything else, Dma controllers, serial transceivers. Oh, it's got everything. But let's have a look at the variant that we have because the variant you have determines the price. You can pay 10 times the price for a different variant that has 10 times the memory.

uh, and transistors on there. So yeah, there can be a huge difference. Anyway, so we've got the Zu4cg here and that's that one there. 192 000 System logic cells 175 000 flip floppies look up tables 87 000.

oh when I was a boy and it's got sixteen, uh, sixteen gigabits per second transceivers. Wow! and it can do like a Pci uh Gen three times 16 interface as well. So it's got 2.6 meg of uh, distributed ram in there. Uh, and it's got this ultra ram as well.

It's got 13 meg bits of ultra ram. so they'd be using this internal memory for all of the uh, application memory and stuff like that. so that'd be running the Linux Os or whatever they're running in there. um, the application memory and stuff like that.

and they wouldn't be doing any sample memory in there because uh, there's 10 meg samples plus the digital ones as well. So we'll have a look at the external memories so you can see the external memory here and it's Micron Joby and we can decode that. They have a nice little decoder on their website. Unfortunately, it's back like it's upside down.

all the electrons are going to fall out. Look, the Fpga code Fbga code is on the bottom and they make you put it on the top here. I don't. I? no.

Anyway, it's uh, this Joby down here and we've got the data sheet for that. and there you go. These are 512 meg bytes. but because this is an 8-bit scope that's per sample, not including any like high-res mode or anything like that.

So 512 meg samples per chip. We've got four chips, so that's two gig samples of memory hardware they got in here, but it's only 10 meg sample memory that they've got. Of course, granted, you've got to have memory for your digital Uh channels as well, because this is mixed signal. so you've got to get your four input channels plus your 16 um, well, which is equivalent to another uh, two Uh channels so effectively like six Uh channels for example.

And then you've got to allow for your uh, boxcar averaging mode as well, which gives you your higher resolution and stuff like that. So, but I they seem to have a lot of memory left. Oh, a lot of sample memory left over. so maybe they've designed it in.

So in the future they can be competitive. You know, Five ten years down the track. when this scope is still selling, they want to be, uh, you know, they lack competition. All the competition's gone to 100 meg or something.

Maybe they can up it. Um, and they should be able to like reconfigure that if you don't have the digital turned on. You should be able to like get more sample memory. So there's two gig samples, not two gig bits.

Two gig samples of memory possible in the hardware. On this thing, they only give you 10 meg samples. So uh, it's all about product positioning and where it fits in. And they sort of like deliberately the products.

uh, pricing, features, and everything else bandwidth to fit in. You know, they don't want to, uh, eat away at the different levels of product that they got. and every manufacturer does it. And down here.

Here's our Emmc memory that we saw on the block diagram and that's handling the application part of stuff. So they're using the internal ram here. They don't need any, uh, you know, program ram. Uh, so that's all internal, but the program is running externally and uh, that's where your firmware is.

your flash, update everything else, and we've got a call for pricing. Oh, end of Life scheduled for obsolescence, and when we discontinued. uh, maybe it's a slight. It's not the exact variant.

I'm sure they wouldn't have picked an obsolete part. Let's have a look at the data sheet. Here we go: Four gigabit Emc, E Mmc, nothing special. Meh, whatever.

Anyway, we've got some chunky bypassing around here, which you need for Fpgas When you boot these suckers up, they go and they go pull your current and if you don't have to get your bypassing right, I've mentioned this in previous videos. Um, that's why Xylinks and other Fpga vendors have entire application notes like hundred pages long of how to power your Fpga. It's that important? Um, yeah, obviously. Uh, we've got, you know.

switching converter over here over here. That's a big ass inductor there. Um, and then, uh, this is our Vco, is it? Anyway, suffice it to say that you do need a lot of stuff to power this beast. So analog to digital converters.

No custom stuff unlike what they have. I'll link in an application down below. I believe it's the Tech 049 Acquisition Arm engine which has a custom their own custom Asic. We're on the higher end uh models on the four and above, not on the three series.

I think the three series might use this same one. don't quote me on that, but yeah, anyway. they're just using off-the-shelf art National Semiconductor Joby. two of them here.

Um, these are actually, uh, dual adcs. Um, to handle the four channels, so let's take a look at those and they are Adc08d 1520s low power, 8-bit dual, 1.5 gig sample per second or single three gig sample per second ad converter. so they're they're dual, but they have to multiplex them so if you want the faster rate, um, yeah, it's going to be used in both of them now. Interestingly, the spec for this 2 series is only 2.5 gig samples per second for the single channel or two channel uh configuration.

Um, or 1.25 half of that. Of course, for the Um four channel configuration where they, uh, use the chip. Now that's actually less than that's significantly under the spec for this chip. They could actually do three gig samples per second.

They doing that for noise reasons. They doing that for architecture sampling reasons. I like processing all their existing software. maybe to match their higher end series sample rates and stuff, don't know, but it's capable of a bit better applications.

Digital oscilloscopes. What a coincidence. So 7.4 effective number of bits? That's what Enob is. Um at 747 48 megahertz um input.

So we've only got 500 megahertz bandwidth, so it should actually do a bit better than that. um, at 500 meg bandwidth. so that's not too shabby. and they only consume a maximum of uh two watts here.

so you can see why they didn't uh, really need to heat sink those and they're running at a lower uh sample rate. so it's probably only you know chewing up what a what and a quarter or something like that per device. There's the architecture there. They just, uh, switch these puppies and use both of them for if you want.

uh, double the sample rate and Lvds pairs Differential pairs is what we, um, saw on the output there. And you can see those differential pairs as we mentioned coming out of the uh. front end and going up there snaking through. And this is interesting.

Check this out. They've actually got a resistor and a cap in parallel on one. One big pad there, so I I don't know like that. I don't.

They want to keep them close. nice and cozy. I I don't know. It's pretty groovy though.

I don't know if that'll be the production version or not. And here's your external, uh trigger input here. so they've probably just got some like comparator action and stuff like that, uh, going on there. Nothing fancy.

Um, that'd be going straight into the Fpga So this is our Pll here. our clock generator for all this, uh, business. I don't see the crystal on there, is that on the bottom side? Anyway, that is this ultra low jitter network synchronizer, two frequency domains, blah blah blah blah blah. So that's what's generating all of our uh, sample clock.

And because this is a lower end model, we're not going to have a real precision crystal oscillator in there. Actually, where is the oscillator? I'm having a Stevie Wonder moment and up in the top corner here. This is our power external power input here. and we've obviously got some switching mosfets here and that's about all she wrote.

And the top side just had that extra stuff over there. But yeah, there's not much doing as far as the digital input here goes. Uh, these are National Semiconductor jobbies, but uh, I don't know. It's got a weird Rcs Md part code on it.

But yeah, they're just comparator um, inputs. so, uh, programmable. Three? I don't know if it has programmable threshold levels because I don't have the ability to enable the digital stuff to actually, um, see on this thing. I'd have to.

You'd have to Rtfm on that sort of stuff. But yeah, um, the output of the comparisons here just goes directly into the Fpga So there you go. That's pretty much it for the teardown of the new Tektronix 2 series oscilloscope. And I really like the single board construction, how they've how they've constructed the whole thing, and the thermals of it and stuff like that.

I know there's a lot of people who complain that a lot of the battery should have been internal, but remember, it's not designed to be a tablet, It's designed to be a both a bench and a portable scope. So anyway, there's reasons that went into that. So um, oh, I have to. oh forgot, ten down on the battery pack.

Hang on and we'll do a quick teardown of the battery pack here and I know, uh, this will probably get uh, complaints, uh from people how it's too big. One of my uh complaints is that it rattles. Um, so yes. Anyway, once again, I've got a pre-production qualification build.

uh, and it could be, um, different. Anyway, there's the battery in this thing. It does actually have a check on it that's pretty groovy. Um, and of course, yes, these things are expensive, but you'll probably be able to get, uh, you know, third-party ones once this comes out.

I don't know if it's compatible with any other, uh, Tektronix uh, products. anyway. um, it is designed to be under the 100 watt hour limit, which is, I believe the carry-on limit for most aircraft. so they deliberately design the capacity to be under that.

So um, yeah, you can basically carry it with one battery in here and you can have one carry one battery in your carry-on bag. so that's pretty groovy. Anyway, you can see down in there like that, they've got two batteries and you could say yeah, it's all a big waste of space and you know stuff like that. But I do actually like, um, how they've designed this to be like grip like that so you can just hold the thing like that.

But yeah, once it's on the tablet, it does make it pretty chunky. Anyway, I do like the attention to detail here. how I mentioned that this is the cover for the back of the oscilloscope. They went to the effort to put a little cutout in there so that you can store it in there so you don't lose it.

Winner! And I thought that uh pin was like an alignment uh pin. But no, they it actually makes that contact up there. so it's a like a big ass, um, grounding pin and it makes contact first. That would be for uh, protection reasons.

So yeah, nice touch there. Anyway, this should should lift off. Let's see what we got in there. Um, yeah.

pretty simplistic. A lot of wasted space of course. Could they have designed it better? I don't know. It's probably the best they could do for removable batteries.

And they wanted removable batteries because you can't actually buy an optional for a pretty penny? I'm sure. Um, like a a charging dock. So you can have multiple batteries and stuff like this and there are specific customers that'll just like drool over that. Being able to like.

You know, it's like having a little those walkie-talkies and you have like the rechargeable battery packs and stuff like that for those who need that sort of stuff for field use. Um, it's just fantastic. And having hot swappable batteries like this, this would have been a big requirement from their, uh, customers. like, you know, a lot of their key customers.

Um, to do that. So anyway, there's the board down there. Doesn't that look groovy? Oh, that's a linear tech jobby, I think that's that's nice. Like just a dual ball.

Oh yeah, it just lifts out. Sweet. Pull the battery out like that and these boards are just going to lift out like that. Ah, isn't that fantastic? There you go.

There's a quick look that is a linear tech jobby. I won't go into details. Oh, it's a mod wire. It's a mod wire.

Will that be in the production version? But as I said as a qualification, build good old-fashioned bodge. There good work it. Uh, there you go Like that's that's a nice implementation. I like the right angled board like that.

Oh that's great. Oh, they got double-sided load. Geez what? You couldn't fit it all on the backside there? Come on. The Pcb layout engineer should have went.

I can fit all that on one side, no worries. But anyway, that is a very nice design. I I really like that like you know and then these pieces just slot in there like that. I like the the mechanical engineers like really had a good time with this one.

Oh and by the way, for those who don't want the uh, super funky stand, I I swear if this was uh, had an Apple logo on it and cost a thousand bucks. um it's It's One of the highlights of this product is the Uh stand, so hats off to whoever designed that. Anyway, if you don't want the stand, if you want a good old-fashioned uh you know, like tilting bail um kind of thing on it, they do actually have one now. Mine is actually 3d printed.

This is how uh, new it was when I got it. they hadn't even done the moulding yet. So yeah, that just goes into the existing screws on the back fell out. Um, goes the existing screws on the back.

And uh yeah, you get a tilting bail. but that won't be 3d printed in the production. Trust me. I'll mention this in the review video.

but I really love these captive screws in here. It's just absolutely brilliant. and you can actually have it like gently sloping backwards like this by only putting in these two. If you put in the two bottom ones, then it's completely vertical.

Or as I said, you can do the uh tilting bail. or you can even put it like that and you can actually have it designed. Sit a flat on a surface, either flat or slightly angled. It's very nice and the sticky rubber stuff on the bottom is really good.

Apparently it's the same magic material like you use on your um, shoe phone inside your car or something like that to like stick it and when it's there like it's really hard to make that budge like it's really like I'm really pushing leaning all my body weight on that and I can't shift it. So anyway, I hope you enjoyed that tear down. If you did, please give it a big thumbs up. And as always discuss down below as I said high-res uh photos of these over my Eev blog flickr account link down below and I've done uh, there's two extra videos on my uh second channel as well.

One is a 40 minute talk with Andy Ted who dropped off this scope for me um, the hand carried it uh, from the U.s So we got to, uh, chat with him before he had to hop on a plane. so that's interesting. and also my initial unboxing and first reaction of this thing because they deliberately didn't tell me they just said I've got a new scope. We're bringing it over and you can see my reaction when I open it so that's on my Eevblog2 channel.

Catch you next time.
