EEVblog 1530 - Siglent SDS2000X HD 12 Bit Oscilloscope TEARDOWN 

I had to stop the video at the metal handle........and raise a glass to Siglent. Absolutely topnotch.

I suspect the Lattice is a serialiser for the LVDS LCD interface

The vent holes in the case and shielding would align with each other if all of the other holes were lined up too, you just have that piece turned around 180 degrees.

THIS is the yolo stuff finally arriving from the Siglent boss. I love it!

Hats off to Dave on maintaining the physique, even the reflection on the oscilloscope screen shows his nerves popping out on his forearm! Inspiration to many hacker couch potatoes out there.

Not gonna lie, the alloy handle that connects to the metal frame definitely sold me!

Wow, that looks neat! None of the old time Siglent oxide/rust coating :D

That's a nice handle. I like it. Hope it starts a trend.

Thats quite a tasty bit of gear! Thanks for open it.

I’m buying it for the handle design. Brilliant 😊

Any time their sending you fancy kit starts getting on your nerves, you can just send them my way. No really, it's no problem!

I love how the handle is made of 2 identical parts

Thou shall follow Ghostbusters cannon and not cross the streams.

You had that back shield the wrong way around at 12:31. You could see the fan through the slats at 4:20.

REALLY COOL BUILD. METAL HANDLE N ALL. THANKS DAVE GREAT VIDEO

yep! they have gone all the way 1980s-SONY construction! pretty cool! it seems the air duct is there to prevent the hot air of the PSU mix with air flowing over the main board.

I like to use CH1 and CH3 way more than CH1 and CH2, because then the sockets are further apart, and it's easier to fiddle around with the cables. The sample rate is obviously another factor, and the board layout, too, but it is simply more practical to use sockets that are not right next to each other.

I always remember the first time I saw a modern scope and how amazing I found it. The fact that it was only a couple of inches deep as apposed to all the old analog scopes that were always about 18 inches deep.

Great teardown video Dave! I think there's a much simpler and sensible reason why the channels are not organized 1324 iso the usual way... Though trace routing concerns are indeed a thing that would have to be considered, the most important thing is easiness of configuration in case of a dual channel option. Sure enough no one wants to be messing with varying signal routing depending on the option, and even less using 2 ADCs on a dual channel scope... The only sensible choice is to organize the signals coming out of the front end 1&2 to the first ADC, and 3&4 to the 2nd ADC. As for the additional FPGA with "mystery" use.... Wouldn't it be for Sync? I don't have much experience with digital scope architectures, but at least on the analog ones, Sync usually takes quite an important chunk of the circuitry... And maybe it was too much for them to accomodate into the main, larger FPGA... Or it can be dedicated to the logic analyzer section.

The more elegant way of channel arrangement (instead of trying to route the traces around each other) would be to just have the channels numbered 1,3,2,4

It seems that the days of the Siglent infamous rust are long gone :)

The memory chips with SEC = Samsung Electronics Corporation.

Siglent has come a long way in terms of quality since its beginnings and it shows. I hope they'll still make scopes for the low end /hobbyists market, though.

I'm impressed Siglent, wow. Did not expect that level.

DCDC chips are never really 'chunky' because of mosfets, those usually best sink their heat into a copper plane and are better off left flat(some do have exposed pads at top for thermal as well though). Integrated inductors are usually the reason for the added height.

The SDS2000X Plus has a 10 bit mode, it is under the Acquire menu, it reduces the memory depth when in use. I have a SDS2504X Plus.

That's nuts!

Nice machine, nicely built. AWG output at the front would have been better though.

1. Remove screen protecting film 2. Put it face down and scrape it against the table thoroughly Sounds like a plan! 🤦‍♂️🤦‍♂️🤦‍♂️

Wave gen on the back side? What an ingenious solution. They should have put some knobs on the back as well.

I saw this one coming 😎

Looks like they paid quite alot of attention to detail, very nice. Not sure if I like the cramped area on the RH side with all the buttons and knobs. However...I could see how that could make for faster selection, not having to move your finger/thumb around alot. Very curious to see how it performs given its price point. I'm really impressed at the construction of the scope.

straight to the pool room with that one!..i havent seen quality like that in..30 years! :P

8:00 that looks like a Samxon KM-series cap. And yes, MeanWell seems to be switching from exclusively using Japanese caps to allowing good quality Chinse caps in their products as well. I have come across Lelon and a brand I forget in more recent batches of Mean Well PSUs.

I think that metal plate @13:00 is using a venturi effect to suck air past the power supply from the side vent.

Speaking of having Ch1 and Ch2 on the same ADC: Ch1 and Ch2 are special channels comparing to the others. They are designated for X and Y in the X-Y mode. For example, with SDS2000X Plus you can only use Ch1 as X, and Ch2 as Y. I would prefer to have full sampling rate in X-Y mode! I don't know how hard it would be to make X and Y selectable channels.

How are the remote interfaces (USB/LAN)? I tire of taking screen shots to document circuit behavior and have shifted almost completely to instruments with complete and performant remote interfaces, greatly simplifying documentation (screen grabs), data capture (including live) and analysis (e.g., Matlab). At my current gig (an RF semiconductor startup), engineers were making frequent trips into the well-equipped lab, then back to their desks, then back to the lab. I put a Digilent Analog Discovery 2 (DAD2) on my desk-bench, and for basic stuff was instantly running productivity rings around them, occasionally using the lab only for higher-bandwidth stuff. The DAD2 paid for itself just in recovering the "out of chair" time. And without a stack of equipment taking up room on the small bench next to my desk!

I'm really not a fan of replacing the warranty void sticker before resale. It's quite disingenuous to the buyer. Myself, I really want to know if something has been opened or repaired before if I buy second hand. I've seen the most horrible repair attempts done to stuff, half the screws missing and it may even have some ESD-damage, if it was handled poorly. Especially if I were to spent the big bucks to get one of these non-entry-level scopes.

To put it into perspective, if you add up the price of just the Spartan 7, Zynq, Artix 7, and the two ADCs, it's already more than the cost of the entire scope itself. Those ADCs cost $1,500 USD _each_ My guess is that the Spartan 7 handles the logic analyzer input capture, the Artix 7 handles the ADCs and any math on the data, and the Zynq is used to tie it all together and run the main OS.

The Rigol looks awesome though

I didn't watch the video for that wou at the beginning of the video but because i like the electronics teardown 😛

Dave, I feel you, I also hate when that happens 0:05 we all can relate, the hard knock life of a social media techinfluencer, who gets swallowed in gifted 12 bit scopes.. Keep pushing thrue, see ya on the other side.

They made this with the idea that it would be opened.

The blank board by the PSU is for a battery option maybe?

Hallelujah!

Lattice has shifted toward serving the low-end/medium size FPGAs, while Xlilinx/Altera has mostly abandoned developing new products for the "does not need a heatsink" market.

Void your warranty, void it all to hell and beyond! Ha. A sign of our times, you don't see diecast alloy parts anymore while they were pretty mainstream in pro gear a few decades ago... Sigh. These days ain't coming back, I guess. One of the reasons why I love tinkering with vintage gear! I love the separate wavegen board. Modularity and separation of concerns... you know what's what rather than having to figure out the jumbotron PCB. 8:28 Facebook? LOL Alignment pin, nice one! The thermal design is really interesting too. I don't get the idea of criss-crossing the input channels. Enjoyed the teardown big time :)

I spent 2k around Xmas st Canada's major siglent reseller and they treated me like a child and missed out on a 2500 dollar purchase at least. I sold my siglent scope and kept the psu as it was an Xmas gift from the wife.

Their airflow is a bit drunk indeed. Zynq is running operating system for sure, they are all the rage with the ZyBo Digilent Boards. Spartan is for the sampling of the digital stuff. The function gen seems to have its own processor. If they use the Lattice as the over scope, my guess would be glue logic, from status bits to buttons to pretty much everything.

I now want to modify my digital scope by swapping out the handle to an all aluminum cast handle. Lol😂

On directing ch1 and ch2 to different chips... is there a similar issue just swapping the trace or wire from the bnc for ch2 and ch 3? Other than changing what people have become accustomed to. I don't usually stress bandwidth anyway, so I use 1 and 2 first.

So many FPGAs - nice ;-)

You'd think they would have just mounted the fan on the back cover, then removed the fan extension and duct.

Hi, Dave, which 12bits one do you prefer more? Siglent SDS2000X HD or Rigol HDO4000? or just MSO5000 & SDS2000XP?

08:25 Ferrite Bead, sometimes.

Perfect timing. I've been on the fence about getting one. $1400 is a lot of money for a scope, but this seems to be so good that I'll realistically never need or even want to upgrade. What do you guys think? Input welcome

Forget about 12-bit resolution, buy it for its magnificent handle 😂

Good teardown video! No review?

That AWG is a pure USB2.0 device

I've been really happy with mine. Except the high pitch SMPS whine in standby.

Hm... no heatsink compound or did Dave wipe it off before putting the exposed parts on camera? It was interesting to see the mix of makers for the FPGA devices.

Could it be ARM's wannabe JTAG, SWD, present in that connector named JTAG? Does match the pincount (SWDIO / CLK / Ground)

Dave! You will have to do some chip muncing to fimd out what the Lattice chip actually does!!!

Delta fans are the best out there. I like the triple blades. A little loud., but excellent cooling.

Those National logo's on the ADC's. Probably the same stuff that goes into Tektronix?

Interesting so many FPGA's. I would have thought the giant FPGA would have been able to do everything? Also interesting that they'd use the obsolete ADC12D1000 from National.

Alloy handles are gonna make or break the deal for me now....cheers.

Looks like a SAMXON cap in that meanwell

Great teardown. Hello dave if you can help me. I have wavejet334 its like bootlop , posted on eevblog forum but theres no one reply. Thanks. Please reply me 😊

So is this just a Teledyne Lecroy Wavesurfer super dumbed down?

The wavegen, is effectively a USB device, Delta is a taiwanese company.

18:00 SEC - Samsung electronics corporation

In your Professional opinion, what would be the Cheapest and most accurate Oscilloscope to buy 2023?

4 FPGAs in one device ?? WOW :) That's why it costs more than Rigol :)

On way they could label the channels to indicate that they share an ADC is to label them Ch 1-A, Ch-1 b, Ch2-A, Ch2-b. But the marketing wankers would likely object since they would say that it makes sound like a 2 channel scope.

Can someone explain, why have low current switching relays not been superseded by silicone, the 4066 has been out forever, is it a crosstalk issue?

Odd to have a Zynq, Artix-7, Spartan-7 and that Lattice in there, you'd think a bigger Zynq could have done it all. But who knows, with how illogical FPGA pricing is, it may have been cheaper to go that route..

Capacitor in power supply is a cheap Chinese made capacitor. Sam Young or Sham Wha or Sun Xo brand.

Almost looks like the wavegen is usb by the pinout.

But the real question is... can you sell it used on eBay?

This wave gen looks like generic signal generator that you can buy for sds 1204xe oscilloscope. It even connects via USB

So where is the justification for the Siglent being so much more expensive than the Rigol? Any reason why anyone should buy the Siglent over the Rigol with the same specs?

They could just label them 1, 3, 2, 4 - but what's the fun in that?

Wait a sec..... There is no more Silent rust signature? Yoloscope become better and better!

What’s the Teledyne affiliation?

Where is the power supply fuse?

Whats total ram?

Meehh. You forgot the Wavegen. Or did I fall asleep?

You will never have a 4 channel scope with 1:3 and 2:4 sharing channels simply because 1:2 and 3:4 has been used for so long it would just be confusing

More "wow"s per minute than an Owen Wilson movie. I think I had a boom box back in the day with a split handle into brackets like that, but I can't be certain. At my age, I don't trust my memory for shit.

A USB like scope with a phone built in.

Honestly, this scope looks ridiculously overengineered. Plus, I wonder what's the actual ENOB for the 12-bit version.

Delta Electronics is a Taiwanese electronics manufacturing company. Not China.

I wonder if I'm the only person who changes every fan in every piece of gear with noctua.

that ain't Siglent, there is no RUST!

😢not akurat osciloscope

i was just thinking about this adc channel length matching: is this not just a complete waste of time as length of the probe will play a role and we know that a few mm will not make any difference?

Hey Dave , sell me one of your Tektronik 2465b's ya hold out ..lol.. I am in Adelaide....Help out a brother..please.

Re: Why aren't channel 1 and channel 2 on different dual ADC chips? The obvious way to do it would surely be not to have them in order on the front panel. Just label them "Channel 1", "Channel 3", "Channel 2", "Channel 4" on the front panel and change the software a bit and you're done with still the same tidy track layout.

Remov the SPO film nau !!!
