Hi everyone!
Owner of SDS2000X Plus could tell me which are the dimensions of the oscilloscope?
Thinking about upgrade my current DS1054Z to this Osci....so far for the price is one of the best option you can get.
Thanks!!
Hi everyone!

Is that the status quo using current firmware? Does it work more smoothly if you enable Zoom mode? Are there other situations where screen redraw becomes so noticeable?
Up to 10 Mpts you don't see any delays. Beyond that, there is this slight delay as seen in the video, of course also in zoom mode.
The reason is some limitation of the access window to the acquisition memory and/or the size of the internal fast RAM. This means a total of at least 80 MB since the 10 Mpts are per channel and this is true for the 10 bit mode (which makes the entire acquisition memory 16 bits wide) as well, so we get 20 MB per channel.
We don't have that limitation in the SDS2000X HD, hence no visible delay even at 200 Mpts.
There is no related delay in real-time (Run) mode, right? I.e. if I move the trace position horizontally or vertically in Run mode, the trace will follow without lag?
Why would you expect it to be better in Run mode - after all Stop mode should be the easier one?
Thank you very much for the details in any case! It's not a severe limitation, but still a bit disappointing to bump into things my measly DS1054Z does better...
That 1054Z doesn't do anything better; it's a toy by comparison. The delays that exist on the 2000XP series are only for long acquisition over 10Mpts. The 1054Z max is 24Mpts total (in Deep Memory mode) compared to the 2000XP's 200Mpts. The only reason the 1054Z might seem fast (it's not) is that it simply isn't capable of acquiring that much data.
I did not mean to be provocative there, sorry if I touched a nerve. Yes, obviously the DS1054Z is a much more limited scope. But if I acquire a full 24 MPts of data and then zoom in, it does let me pan back and forth without redraw delays. Which is why I kind of took this behavior for granted and was a bit surprised to see the delays in the SDS2000X+. No worries, it's not a deal breaker!
Why would you expect it to be better in Run mode - after all Stop mode should be the easier one?
I had expected Run mode to be unaffected since, in my understanding, it only acquires a screenful of data anyway -- hence I thought the "deep memory" access with its wait time would not apply.
Thank you very much for the details in any case! It's not a severe limitation, but still a bit disappointing to bump into things my measly DS1054Z does better... It may be an indication of Siglent's focus on powerful analysis, where interactive viewing and manipulation occasionally take the back seat? Like with the lack of a horizontal vernier, which also was a bit surprising to me.
We often see such complaints.
Users that come from some old analog CRT-oscilloscope - or older digital scopes - are disappointed that with their shiny new DSO they can't just enable X-Y mode without bothering with the timebase (which is just disabled on an analog scope in X-Y mode).
And why can't they have their beloved alternate trigger (to watch two unrelated traces at the same time) and why the heck isn't there an ETS-mode available, as even the old Rigol DS1052E had?
We cannot even be surprised, because one needs to know a bit about the internals of oscilloscopes to understand the reasons why progress does not always mean just additional features but can also lead to different solutions. Sometimes it looks like a step back, but almost always a rationale can be found for it.
That feels a bit unfair and like you are writing me off as "uninformed and stubborn old-timer".
If you aren't going to use the scope, or other Siglent equipment for a few days or more, is there any downside to fully unplugging them ? I thought I noticed the clock didn't change when I had it unplugged (2104x-p). I don't care about that. I think I read there's no internal battery ?
Sometimes I'll go a month or longer without using a scope or AWG. And I don't like leaving them plugged in. My SDS1204x-e is basically in storage since I got the 2104xp. Should I plug it in sometimes ? Is there any ROM or something that needs power once and a while ? (my poor old 1980's scopes, I haven't used them in 3yrs, I better use the variac when powering them up next, just to be safer)

I've identified several bugs:All the above bug reports have been accepted by Siglent, entered into their bug-database and will be corrected with the next firmware.
- In Dots display mode, the selection of x versus sin(x)/x should be irrelevant. Other scopes based on the same platform show a correct behavior in this regard.
- Waveform update rate generally is a bit on the slow side, and there is a huge difference between x interpolation and sin(x)/x reconstruction. This problem does not exist in an e.g. SDS6000A.
- Auto Trigger does not work as expected. it is slow and erratic if there's no signal present, e.g. for noise measurements.
- Mains Line Trigger does not work as expected. it only provides about 9 triggers per second on a 50 Hz grid.
All the above bug reports have been accepted by Siglent, entered into their bug-database and will be corrected with the next firmware.
Have these indeed been corrected? I looked through the firmware release notes, and could not find any relevant changes mentioned in the 2022 and 2023 releases.
now at least the SDS2000X HD behaves the same as the SDS2000X Plus.
The original complaint was that there shouldn’t be any difference between x-interpolation and Sinc-reconstruction in dots display mode. Back then, this was true for the SDS2000X HD and the SDS6000. But in the meantime, quite unexpectedly things have turned the other way round: now at least the SDS2000X HD behaves the same as the SDS2000X Plus.
