Tried it yesterday, today the same problem.
The problem is that i cant reproduce the issue, its mostly the first boot of the day and after a reboot it works flawless for hours.
Things to try:
Secure erase to clear any hidden settings. (Save/Recall menu)
Factory Default then reboot then Self Cal.
Reboot.
Use normally.
Note settings at finish of day and if these have an effect on the next day instrument hang.
After above.
Just maybe we need connect you with a Siglent engineer so to get info from the scopes Debug menu so they can analyse what's going on.
I dunno about that... it almost sounds like it needs to be heated before it starts to work which implies a broke connection, maybe a bad solder joint.. if its still in its return window i'd get another
Heres a viedo of the behavior.
In the end it changes channels slowly, but i cant do anything.
Looks like a kind of emergency failure protocol or self testing.
Hi!
I originally considered purchasing SDS2000X-E, but then accidentally found this thread. And now I really don't know what to do - SDS2000X+ seems much more interesting model, but it's more expensive than a base-level used car in my country... As I see from this thread, one can purchase SDS2104X Plus and upgrade it up to 500 MHz using just an ethernet cable, web browser and a python script, right? Also it seems to be possible to unlock the arbitrary waveform generator this way, right?
Unfortunately I cannot afford this scope right now, so I have to wait a while. What do you guys think, is it possible that Siglent is reading this thread and will change its private key in future so no more free upgrades will be available? Also, does the lowest 100 MHz model really have the same high-frequency path as the highest 350 MHz one? It's said on official sites that only one upgrade level is available - from 100 MHz to 200 MHz. Could it be that Siglent builds their scopes then tests its capabilities without BW limit and sorts them according to test results - the best ones are marked as 350 MHz, the middling as 200 MHz and the worst scopes as 100 MHz? In this case one can formally upgrade 100 MHz unit up to 500 MHz but won't get the same gain frequency characteristic as upgrading the 350 MHz scope.
FYI all options except MSO are now free as part of a promotional package.

At this point, everybody must decide for himself what further hacking concerns.
Do I really need more bandwith for my work with it or leave it to 100Mhz to provide having the warranty for the next 3yrs...

I was/am in a similar situation recently. Scopes are a rabbit hole and the upper bound is multi-GHz units at $100'000+ prices. Before you know it you will be looking at units well above your means.
The only way to stay grounded to reality is to buy what you NEED.
So my advice is to think about your use case and what you are likely to work on in the next few years (yes, a scope is expected to last for years).
Then do your purchase based on that, and not on whatever is available on the market.
As noted above the 500MHz upgrade is available only on 350MHz base models, so be careful with that. But do you NEED so much bandwidth ?
Hey guys, filthy zero poster here.
I have been investigating which scope I should get for some time now and the SDS2000X+ series is a candidate.
But I do not fully understand the decoder specs listed in the datasheet (top of page 13) where it states that it has 2 decoders of full duplex type.
What does this mean in practice?
Scenario example 1: it can at most decode two different pairs of MOSI+MISO, originating from two different SPI busses at the SAME time <-- i think this should be okay
Scenario example 2: it can at most decode four different MISO lines, originating from four different SPI busses at the SAME time <-- i think this is out of spec?
Am I understanding this correctly?
- Does anyone have a screenshot of maximum decoder usage in action?

500MHz upgrade is officially available only on 350MHz base models.
For "other methods" there is no limitations.
I've just got my SDS2104X Plus. Everything is working pretty well except for the calibration signal, it seems that it is internally bad soldered or something as it will change all over the place as I move the probe connected to it. Tried with another scope and get the same issue. I don't care much about the calibration issue, but this is making me think that the scope could have other problems. I don't want to send it for RMA and have to wait a month for it to come back, anything I could be missing?
Try setting the AWG to 3Vp-p 1 KHz square wave and probe that as a sanity check. There is a chance it's a dicky probe although its been a long time since I had a dud PP215 probe.
Maybe the grabber isn't making a good contact with the probe tip.
Double check this using different probes.

Clearly the calibration connector is not properly connected internally. I've tried with other source of signal and the probes are perfect, also tried with other probes that also work without problems and fail to get a proper signal from the cal points in the SDS2104X Plus. And if I just make a bit of pressure to the right on the signal connector I'll get a proper signal.
I suppose I'll wait a month or so just to see if there is anything else broken and send it for RMA after the holidays. The worst part is that I've just sold my old scope and waiting a month for the new one to be replaced it is going to be hard
I bought it from Saelig, should I contact the distributor or just talk to Siglent America directly?
Let Saelig handle it and/or advise you on the best method to get it addressed.
Which are you closest to ?
