Looks like good value!  -  I'd definitely be interested in seeing a shootout between the current $1K scope crop.

[kcozens]

I hoped Dave had spotted the serial interface and would connect up to it and see what messages were output. The messages that stood out for me were where it said Linux kernel 3.19.0 SMP PREEMPT, ARMv7, and machine model of Zynq Zed Development Board. I have another machine I work on that uses Uboot and also gives that same CRC error at startup. The main(?) processor may be running at 383MHz with 1528.62 BogoMIPs. It also appears to have 2 additional Cortex A9 CPUs (restricted from 4??). The two PREEMPT RCU CPUs benchmarked at 3057.25 BogoMIPs.

I also like the warning about a setting in the configuration file for Fontconfig. It also said it was listening for a VNC connection on port 5900. Sounds like you could get a remote display (and control?) for the scope using the Ethernet connection.

Can someone please confirm which models can be hacked to 500Mhz BW?

I had a bit of read on the long 49+ page thread and some owners have indicated that lower end 2104X plus 100Mz model had the same front end as 350Mhz?

[boffin]

Two things;
1) The remote screen is via VNC, an open protocol, which should allow any VNC client, cool
2) Why would someone buy the 70MHz version when the 100MHz is cheaper? (see below)

Yep, someone posted a photo of the 100MHz front end, same as the 350MHz one apparently.
Haven't double checked myself.

That's the X, not the X plus. There is no 70MHz X PLus

Hi,
the one thing that stood out to me when scrolling through the Manual of this Scope was,
that apparently you can run a Bode Plot using your external Siglent AWG...

@EEVblog maybe interesting to see if that actually works well?

Welcome to the forum.

All Siglent DSO's with the Bode plot feature are capable of this via USB or LAN connection.
The main advantage of using an external AWG is to be able to push to higher frequencies than the scopes AWG option provides.

Ah didn't know that, this was the first time i ever saw such a feature in a Scope.
Seems like a nice addition to get some more use out of your Siglent AWG.

Connection is very much plug and play via USB and a bit more involved using LAN....settting IP's and all that stuff. 

Here's some detailed study examining the updated Bode plot version now in the X-E 4ch DSO's and similar capability will be in the new Plus models.

By the way: the 'old school' wiring to the display is most likely for LVDS signals. TFT panels with resolutions over 800x480 tyically use LVDS because the clock rates get too high for using FPC connections.

[Mr. Scram]

A new hardware video! I've been hungry for one. Even though I like my name brand top tier lab equipment a lot, the bang for buck gap between a Keysight or R&S offering and oscilloscopes like there is getting fairly big. The Siglent quality seems to be slowly increasing too. No rust, no major flaws or broken features which show it's a cheap instrument. The internal layout is a bit peculiar and the silly knobs and colour choices aren't ideal, but it seems Siglent is a little less temperamental than Rigol which generally seem to include a few significant flaws or drawbacks. I'm thinking of the sluggish and buggy UI on the otherwise quite good MSO5000. I'm interested to see if and how the big boys react to the oriental outfits intruding upon their turf. I guess it's not just hobbyists any more. They may very well not react at all, but that'd inevitably lead to asking what went wrong in 15 years' time.

They seem to be reacting by offering educational and easily hackable models for hobbyists, while still attempting to protect the professional market (and maintain professional pricing power).   Even so, the bang-to-buck ratio of the Oriental equipment is hard to get away from.

If 10 years ago you'd have said that you would be able to buy what's essentially a 500 MHz four channel oscilloscope for $1400 people would have said you're a nutcase. We have to remind ourselves that the Agilent now Keysight 2000X series wasn't even introduced back then. The introduction of a "cheap" 200 MHz four channel oscilloscope was considered democratizing high performance oscilloscopes at a reasonable price. Those have held up surprisingly well, but the Siglent is essentially vying with the 3000T which was introduced later at a much higher price and which obviously is much harder to upgrade to better performing variants. I'd be surprised if Siglent can compete quality wise, but the performance and features seem to be there and not-terrible. I'd hate for the western big boys to do a Tektronix and fade to irrelevance in areas they once were dominant.

[fanOfeeDIY]

When I as maintaining the oscilloscope chart, I realized that the 2ch version model SDS2102X-Plus which is 999USD offers 100MHz model only.
The 4ch version SDS2104X-Plus (100MHz) have lineup going up to 350MHz.

The front end of SDS2102X-Plus and SDS2104X-Plus might have the same front end or SDS2104X-Plus might have better one.

[tom66]

Really interesting architecture ...  I'd love to know what ADC they are using!

No doubt that processor top centre is a Zynq.  I've designed a board with one on it, and the layout of the DDR on the left and clock source at the top, with the FPGA banks running along the other columns, is telling.  They have a dual-channel DDR interface there and are presumably using that as part of the acquisition/display control.  That should get them ca. 4.3GB/s memory bandwidth in standard grade.   The 512KB L2 Cache and 256KB of OCM makes the Zynq pretty fast even with limited memory bandwidth.   What I *don't* understand is why they then have a separate SOC.  Is that just handling the UI?  The Zynq has a USB and Ethernet controller nearby, so the obvious thought is *that* is the main SOC, but Zynq doesn't come as-standard with a display controller (you need to instantiate one on the fabric and there's no GPU without also instantiating that, which uses most of the fabric of the small devices, especially if you want to avoid saturating your RAM), so perhaps it is *only* rendering the waveform and summing the image together with the other SOC.   

The two larger devices above the AFEs are obviously the acquisition FPGAs with their associated DDR.  We can see here instead of a dual channel layout that Siglent have used a dual MIB layout so there are two discrete memory controllers.  If this is standard Spartan-6 stuff (the Chinese seem to prefer Xilinx; perhaps it's taught more often in their universities?) then they will be close to the money on memory clock - IIRC the MIB is limited to 533MHz with DDR3 at standard speed grade, which gives them a raw memory bandwidth of 2.13GB/s.  2GSa/s will be utilising one memory controller almost entirely.  I suspect they either use the RAMs in parallel or alternately to implement some form of double buffering.

It's a rather interesting architecture, and with the known cost of parts, Siglent can't be making much on the 100MHz 4 channel version, which is about 900 euros.  The silicon alone is going to be bumping on over 400 euros of that price unless they have got some ridiculously good pricing from Xilinx.

Hej Dave,

I was wondering if you can help, or SDS2345X Plus emitted the magic blue smoke courtesy of our new apprentice who flicked a ground lift switch on one of our amplifiers.

DUT are normally floating, but I turned my back for one minute and the boy decided to take the scope down, I think if I am honest he was sick of the scope getting the better of him and decided to scopicide it.

It is a cheap scope, but I don't like waste. Purpose of the message, do you have any pics of the flipside of the acquisition board? there are three chips that can be served with fish as they are fried, I am tried to use some deductive reasoning, but although I think I know what they are doing, I have not a clue what part number is.

Channel 1 and 3 work fine now, I restored the -5VDC rail and replaced a ton of SOT-23 NPN that were kaput, got 1 and 3 back up, heartbeat on all the chips is good.

Anyway, not to ramble on, if you have a pic of it that would be really helpful, I know on the teardown (which I watched top to bottom in the hopes I could screen grab a win) but there is no flip side.

I spoke to Siglent, they want 800 buck for a new board, that is a non-sequitur for me as I can repair this one.

Any help from any of this excellent community would be really appreciated.

Kiitos

Welcome to the forum
When doing a mainboard warranty replacement a few months ago I took a few pics and posted them here, one of which is the flip side you seek:
https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-coming/msg4176037/#msg4176037

BTW I still have the old mainboard and could take more pics of it if required.

[BjornTheViking]

Hej Bud,

Thank you so much, I can see the chips, they look much better on your board! but they are too low res for me to see.

If you have any high res image that would be great, and again thank you for making the time, I could highlight the chips that are in question also.
