Hi Just a little preamble to this video. I Actually shot this video a couple of weeks back and I was just about to release it as a world exclusive when Siglent said hey, well put it stop please Um, because we're going to change the marketing on this scope. Now You'll hear me mention during this video that it's a 100 Megahertz model scope and that it is three hundred and fifty Nine dollars. It's actually going to be three hundred and seventy nine dollars and it's going to be two hundred Megahertz only.

So I am getting a new version of scope but this is the original one they sent me I Don't believe there's any difference at all between the hundred Megahertz one. I'm tearing down here and the two hundred Megahertz one that they send to me I Believe this still has the two hundred Megahertz front end and it was just being software limited as these companies do for marketing reasons. but Sigler have decided to go against that and this is going to be and then entry level 200 megahertz scope for three hundred and seventy nine US dollars with the free serial decoding and the one Meg points FFT and everything will see inside this video. So I just wanted to clarify.

if you see that further on or hear that further on in the video, it's changed anyway. I'm with the show hi another world exclusive here. We've got the new Siglent ultra low entry-level scope. It's the SDS 1000 X-series and you may have said Dave I've seen that before.

you know that on the blog a couple of years back? Yeah, I have. but this is a new - II model not to be confused with the other - models they've got available. This one is not actually released yet. It's been released in April ish sometime and the thing about this is that it's a three hundred and fifty nine US dollars supposedly is going to be the retail price on this puppy.

Now it. The way it differs from the existing 1000 X-series which they're still going to have, is that the 1000 X-series has options for a Wave Gem and a logic analyzer as well. Mixed Signal Scope This is not that there's no option for a Wave Gen. There's no option for mixed signal.

A scope. Don't even think about it. this is just your bare bones entry level to Channel 100 megahertz. Our bandwidth scope for 359 bucks.

One gig sample per second. But this is actually a completely different design to the existing 1,000 X-series inside which we'll take a look at. It's super fast, super responsive. 1 Meg points FFT And one of the big selling features of this and a lot of people are complained about this over the years is that why companies charge for serial decoding.

Well, this one has a built in for free beauty. as you can see the front panel layout. it's practically identical to the existing are 1000 X-series except it has an extra button here for the wave Gen which this one doesn't have, but it's got the nice auto roll mode with the roll button in that I've been not using this in a debugging repair video I'm using at the moment and I actually quite like that feature. It's working quite well and it's got.

you know, the USB to save your waveforms, everything else. Everything you typically expect in a bare-bones to channel scope and the inputs are a standard 1 Meg 18 paths are 400 volts peak so reasonably high voltage inputs on the back. yes, LAN is standard for the three hundred and $59 scope and we've got our pass/fail and trig out and USB device as well. Your basic functionality very nice for the price.

Anyway, you know we say you're on the EEV blog, don't turn it on taken apart. Interestingly, this one says the normal power 25 Watts max. Most scopes of this sort of, you know, little for small to four channel scopes and normally you know, like say normally 50 Watts So that's going to be interesting because there's some new circuitry inside here that's different to the original series I Remember what the original series was, but yet this one could be law of hell Now I've done a video on how to remove these are calibration seals without damaging them. so clip out.

click up here somewhere if you want to see that. but and screw that for today, you're here as usual. Got the two with screws in the feet there. but really, we've got the screws vertically on the top this time and not in true thought like that.

By the way, if you want to see the previous tear down of the original 1000x series, click up here somewhere this stupid new YouTube card thing because it turned off annotations Youtuber like you can't just completely abandon annotations now. So I can't like annotate videos and don't get me started, they reckon cards replace it. they do unbeli I can't leave a regular text comment in a card, but I can link to videos so tear down for this up there somewhere. Hmm.

Anyway, let's open it up. Well here we go. Let's see what our built down to price scope is like. like I still can't remember I should go watch my video for the other one, but that's interesting.

Usually we have a two. You know, the power supply separate then comes off this one. it looks like that top. It's slightly different to how they normally are.

Anyway, let's crack it open like this up there was only two screws on here or Phillips by the way. different to the regular talks you find. and bingo we're in like Flynn aren't no separate shielding on the power supply. they've completely separated that single ball construction down the bottom.

We'll have a look at that, but so that's in, you know, Interesting. This is supposed to have a 500 micro volt front end, but of course it's all shielded, so you know, No worries, they're probably, you know. I'm not hugely concerned. there's nothing inherently wrong with that.

It looks like quite neat and tidy actually. I Do like the look of the power supply. They've put a little cable tie on there with the earth first strap and the main ribbon. the power supply ribbon cable here, so that's interesting.

I Have to cut that to move it out of the way. to get the UH photos and look, they've put Loctite on the connector. Nice touch. They've done it over here with a fan and they're out gone to the effort to route the wire under there under the main screw there so it's not flapping around in the breeze.

Nice attention to detail. I Like it. And in terms of airflow here. we've got the air blowing out of this side here and it's sucking the air from over this side.

There are events here, but they are in the top or bottom, so that's blowing over the power supply and over the heatsink fins as well. They're even correctly oriented like that to get the maximum airflow over them. Nice Power supply. Certainly neat and tidy.

It's got all the business. Nice. Our fully encased a fuse. there.

We've got isolation slots absolutely everywhere. Look at a primary and secondary here with the optocouplers. Very nice. As our main switching transformer, we've got a requisite mode protection and common mode.

I Choked on the input. The Earth Lead is your standard standard fare that seams are tight enough, so that's a neat looking power supply there. Celesta, Call the caps down Lille on caps. Yeah, yeah, not exactly Panasonic's and you might not be able to see it, but they have gone for hourly.

lawns pretty much everywhere else as well. They look like the Gold Series ones there probably are low ESR jobs so yet Lisa Stuck with the one manufacturer, but you know this is a bottom of the range scraping the barrel 350 odd dollar retail a scope so that's a pass, which is neat and tidy. now. Unfortunately, to get the mainboard out, it looks like I've got to do our four self-tapping screws into the top metal work here.

So this top metal work lifts off because there's no nuts on the front Of course for the B and C there on the middle on the inside. but to get to the last nut, I got to take the power supply off and I think they got a bit of a look and tied on the bottom. there elephant tied elephant hide on the bottom and they're just insulating that the backside of the board for those playing along at home. Look at that.

Nice touch. High-voltage isolation slots between each pin of the bridge. rectifier. Neat.

That's all this is supposed to pop out night night. Got to undo the ribbon cables first. Don't selves. A nice big juicy ferrite right across the main LCD ribbon cable.

there. Could that be a last minute? you know? Am I? oopsie? Perhaps. Tell you what. I Really like the fact that you can just swing out the power supply like this and get in there for the board? of course.

No touchy, don't accidentally scrape the bottom of the board down here. but yeah, nice access for hacking. Speaking of which, check this out. Look easy access right on the edge of the board and labeled the not only the JTAG interface but for all the world.

Like a UART because that just like beautifully laid out and there's even an extra pin header over there. I Don't know what that is, but yeah, like purpose-designed readily accessible for hacking. Go for your life. and I Forgot to mention there's no sign of any of the trademarks siglent rust on the on the Chevy on the edges of the Chevy.

So yeah, they've upped their game and here we go. Let's have a squeeze inside. Got this under the Sugano microscope. It's all on one board.

as you can see now, this is very interesting because the heart of this is the Xilinx Zinc process. That they've completely changed architecture on this thing that's what's under the heatsink. sorry that's our glued down I won't be taking this off. it's the only one in the country so I don't want to ruin it so I don't know exactly which Xilinx Zinc model that actually is Anyway, it's the Zinc process so that's all you need to know.

which we've seen before in the GW in Stick 1000v series and that's what gave it. It's incredible bang per buck performance in terms of FFT processing the one mid point FFT which is what this cichlid one has as well. And of course, the beautiful thing about the Zinc processor is that it contains not only as I links FPGA in there a reasonably capable one, but also I and I Think it's a dual-core processor in there, so you know tightly-knit coupling between the FPGA and the internal ARM processor and hooked up to our Ddr3 memory. I believe it uses I Haven't actually looked up those numbers, but you can.

If you're playing along at home, they should be Ddr3. You can see all the lengths I match in there or the classic length matching stuff. They got the little wiggle wiggle wiggle wiggle. Yeah to make them all identical.

our length because you got to link match those puppies. Otherwise you get timing problems at such speed like this. Now the previous 1000x series from Siglent, we've seen the teardown. I'll link it in down below it's actually got a it ran on the black fin DSP platform.

So they've completely changed the platform that this thing runs from. Although I'm sure you know a lot of the code is compatible and everything else, they probably was able to port that over relatively easily. But yeah, it's They've got it all on one board. and the interesting thing is is that it is on the main board where as we saw it on a daughter board.

just the process apart on a daughter board inside the GW in stick. and that was to lower the cost because you need to fan out this: BGA You need a big multi pin. It's a multi-layer board. You know there's all the bypass caps and everything else.

They've found out almost every veer on the thing by the looks of it. and to get that out, you need like an eighth layer board or something like minimum to get that out. We've also seen that motherboard approach in the or the daughter board approach in the new Keysight 1000 X-series as well. Once again, to get the cost down, keep all that multi layer complexity on a smaller board.

but hey, for this ultra low end one, it's different. So I'm very surprised to see it integrated into the main PCB but the PCB itself is relatively small, so maybe that's why they can get away with it. and they can fit multiple ones in the one pedal of course. Yep, you can see the mouse bites There you go.

You can see the mouse bites there and they're on the board which shows. It's all penalized so you could probably fit. You know this size optimized. there's probably two fit four of these like on one PCB paddle or something like that.

so that's how they can get the cost down. Otherwise, the bear board alone. if it's eight or ten layers just because you need this part to be high-density because most of them, the rest of it can be four layers. No problems whatsoever, and you'll get away with that.

Fine and dandy, but all this stuff is. you know, probably eight layer just to fan out that pain-in-the-butt BGA package zinc processor. but that's the price you pay. But it's interesting that they haven't gone for the daughterboard approach.

So I'd say because this board is pretty darn small in the scheme of you know. complete motherboard. A complete oscilloscope motherboard type bar boards. You know they've done well, so they're You know that would have been a real cost off optimization exercise.

Anyway, that looks like a lead. Is it what? HL um I Give you a challenge I don't thing I've ever seen I hate your designator before, but that looks like I mean it's got it's got a series resistor in there, so okay, or is it some sort of ambient light sensor? I Don't think so. it's probably just a lid. like a heartbeat lid or something like that.

Anyway, what is all this array of jumping array of transistors around here? for what got to test points associated with? it seems to be hooked into the Zinc processor up there, but whoa, like why um, what are they doing I don't know, that is very curious. Um hmm. Anyway, JTAG Interface: no Orys workout point, one inch header on there. so what do we got there? Just a 7404 got ourselves a crystal there BOF Pc thanks for telling us all the information on that one pen not I'm just a 240 for some Jelly Bean logic and the ADF 4360.

and if we go on over the datasheet, that's our PLL basically our VCO our voltage controlled oscillator. That's what generates the main our clock there. So yeah, it's the jelly bean one I think we've I've seen that before and but it's all about of course the loop components that you actually put inside this thing. and I'm sure if you scroll down far enough you'd find examples of various loop components which are some companies who shall remain nameless.

or I go I have screwed up the happen that loop on the end with all the building registers and everything else. Anyway, there's the loop filters for those who want to analyze that to see if they're goofed up. Go for it. and moving on from that.

What are we got here? We're entering our trigger section of the board: a Dcmp I think that's just a comparator and certainly for HC 405 Three got to have some 4000 series CMOS in there. no workers cells. The Classic: Five, Nine, five again 74 HC 405 Why no, it's all happening all jellybean stuff. Anyway, this is the trigger section.

some local regulation across their analog. VCCS got its own separate 5 volts and nice little test points or labeled and that's the interface. but people want to see the ADC We almost missed it. There it is.

it's ahead 1511. Let's check it out. and here it is. It's a wank example ad converter.

So no, we're not going to be able to overclock this thing any time soon. and we've probably seen this in other parts as well. Typical applications digital oscilloscopes, thank you very much. Oh yeah, it's a purpose design for this sort of thing.

And of course it's got the four channel interface in there. And of course, the one gig samples per second will have. of course, because it's not one gig sample per second per ADC, it's one gig sample per second total. So when you turn on that second one is just going to have and well, I'll link it in down below.

For those who want to check it out. Alright, calm down. I Know you want to see the analog front-end Well here it is two identical analog front ends. I'm sure they are I'm not going to look, but you're pretty sure they're absolutely identical there.

Now this actually differs from the analog section used in fact I'll try and put them possibly side-by-side here in the shot. different to the one that used inside the other 1,000 X-series So this is the 1000 X-series and looks like they've got a slightly different front end. there's two. realizing this one, there was three in the I'm going to call it the older one because this one is brand spanking new and we've got some trimmers there which I don't believe that we had to trimmer caps up there that we didn't have on the other one.

So yeah, two relays. but apart from that, the top section. Actually, all this section in here looks pretty close to identical. so the previous one had a 200 megahertz bandwidth.

This one is available in a 200 megahertz model, so I'm sure absolutely sure that the base model unit if you bought one hundred megahertz version, it's going to have the 100 the 200 megahertz analog front end and they just software limit it. But if we have a closer look at that identical section that we had before, we're going to have Cosmo relay. they're a 595, our port and digital port expander of course and an 80 370. Let's check that one out so to be verified later.

but I'm pretty darn sure that everything is identical, including the differential weight gain output amp and the variable gain amplifier in there. I'm pretty sure that they're all the same that we had in the previous model, so I won't go through details. There's the top half for those who love to take screen captures, but I've got high res teardown photos down below. but I don't know I didn't get them out of the cigar.

no microscope. So there you go. Beautiful. Oh look at that.

It's better than a macro photo really is, but it's limited to Nineteen Twenty by Twelve eighty. Gosh darn it. And if you want to see the bottom of that, and of course you do, of course you do. There is the bottom for those playing along at home and there's not much else.

Got a nice big cutout in the ground plane there cuz they didn't want to upset the applecart, but that looks all neat and tidy. That's a 200 meter intend. I'm not sure what else I can now show you there. That's about all she wrote on the new siglent 1,000 XE main motherboard.

they've really, you know there's not much in your modern our scopes. Then again, if you look at an old to someone on say it I'm sure look at the old Tektronix TDS 210 for example which is like 25 years old now or something and that had bugger all in it. but it also had bugger all performance as well. But this thing is a very remarkable and so thanks to the Zhiling Zinc processor down in there and nothing else, that's it.

That's what handles all the grunt in this thing. one. MIG point FFT I Believe it's got hardware serial decoding. It's got a complete digital trigger system which is effectively zero jitter.

They call it because it's digital and you get just one. Yep, Anyway, Um, because you can extract it out instead of doing the triggering in analogue. Anyway, we're probably pros and cons both ways there and it's all integrated inside the zinc and the FPGA part of the zinc in there, whereas the arm core of course would be running all the the OS and the display and everything else. So yeah, oh, we've got another HL There There you go.

HL 1 HL 2. They're going to be LEDs I Don't know I Haven't powered this thing up with the back off it yet. It works. Swishy fleshie And you bet yeah that TX Rx is a you are tada.

Oh Dump this on the Eevblog forum for those playing along at home who want to check out this, but once again, it uses that. You boot just like the 1000 X-series that were playing around with last week and or ECC is disabled and then 256 Meg bits. Let's go I Don't know. Anyway, you can go in here.

let's see if there's anything interesting. Is there armed? Linux Kernel: This is not going to be a hacking video by any stretch, but we just want to have a quick booting. Colonel booting Linux on physical CPU Linux Version 3.19 Point zero for those playing along at home. GCC Version: There you go.

Ah, it's all happen. It's all happening. So is there anything interesting? So that's all the Linux boot stuff USB blah blah blah blah blah zoic SCADA Xilinx a excited Dma engine. Successful.

That would be for dumping all the high speed or open SPI Dev hate see 595 failed. Ah what? That's the speak to a 5 9, 5 under. but it got this one. Yeah, did it.

Hmm. Anyway, that's the port expander I would be getting for the that they use on the front ends, but they might not. might have. No, we didn't see a 5 9 5 anywhere else on the thing did we.

So I think we're consumed that that's the that's the front end. but hmm, there doesn't seem to be anything hugely into a test I don't know. I'm not going to look into this in detail. the dumps down below for those who want to check it out.

Oh no more stuff down here Skippy um what else we go driving means of the Albemarle blah blah there. Our module doesn't sound that great anyway, but this may not be a release version. so yeah, don't take this as gospel and bingo we can actually talk to this I Tried help and I helped not found being Ashe whatever that is I don't know. all the Linux people are probably screaming at me and I try to help games of course because the more complicated these things are, the more they have to help you out apparently.

So I Help not found Oh hang on I know what to do damn it. taking out the password you.
