There are several videos of the RTB2000’s XY mode available from 3rd party reviewers, including one pretty thorough one here:



Mikes Electric Stuff has also played around with it a bit with some unique combinations:

Last year I had occasion to use XY mode on my Keysight MSO-X 2024A, to characterise the transfer function of an opto-isolator circuit (tweaking for best noise margins with lowest power dissipation). It worked beautifully, including a simulated 'spot' following the signal - which was a triangle output from the built-in generator. First time I'd ever tried XY mode, though!

That's great to hear. Please keep me updated! I'm in the market for a DSO and the Siglent is attractive. I just definitely don't want to see an XY mode like this:

Yes, to properly evaluate it it needs be videoed.

The new FW I've mentioned is discussed here:
https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-in-depth-review/msg1555936/#msg1555936

It's not up on the Siglent websites yet but should be in the next few days.

Well I've managed to find a copy of the new SDS1004X-E series FW and the XY mode is dramatically improved.
With lowest memory depth set it really flies for a cheap DSO.  :)
But unfortunately even just a 10s video is 30+MB on my phone so it's too big to post here.  :(
Tonight might be YT A/c setup night.  :scared: Done.

Any plans for the two channel SDS1202X-E? Seems that despite belonging to the same "family" firmware development is diverging a lot.

The last 1202X-E FW was back in Jan so any improvements it supports that's been added to the 4ch X-E should follow in time. The divergence is due to the substantial additional functionality the 4 ch models provide and the need to get all that stuff right.
