See -> https://www.eevblog.com/forum/blog/eevblog-683-rigol-ds1000z-ds2000-oscilloscope-jitter-problems/msg550964/#msg550964 This is already up to 12 pages in only two days. I'm posting this alert here because I didn't see Rigol O'Scope experts here such as 'marmad', 'teneyes', etc there that could be valuable contributors to understanding the issue. And further we should all at least be advised that this issue is being discussed. I also believe that some DS4000 users are experiencing the trigger jitter issue (with the AC trigger mode).

Thanks for the heads up. As I noted over in that thread, we've been talking about problems with AC-coupling the trigger for over 2 years now in this thread (check out the bug list or search the thread). Few of us original owners use that setting because of these problems - and I've never found a single instance in my use of the DSO in that time where I needed it. The other jitter being discussed is not present on the DS2000.

Thank you 'marmad':
I just found your post that I somehow missed before reading through the whole thread. I must have fallen asleep for some of it.
Anyway I for one feel much better as a DS2000 owner seeing that its AC Triggering issue has been known about for a long time. It is very bad, so hopefully it will get corrected by Rigol.
Thanks!

This is a Post from Dave about the D1000Z (with 5uS Jitter / AC Triggering) and DS2000 (AC Triggering) Jitter issues:

UPDATE FROM RIGOL
1: We have reproduced the two issues in R&D side;
2: All issues can be fixed by firmware updating without deleting any feature;
3: The trail firmware form R&D will be released in early next week, that can be used for Dave or some urgent cases.
Good news: It appears that we will eventually see firmware fixes for these issues after their Beta testing with EEV's Dave Jones, etc. has been completed.

Triggering ac nothing has changed.
I find problems, attaching two pictures ... this's not normal!!!

Gilberto60 Is this what you like to see with 2 different frequencies?
Note , Select SourceA or SourceB in order to adjust Trigger level for each Chan

hey all
I've got a question: how good is the math function of the DS2xxx?
I have 3 DSOs here: 1 yokogawa and one philips pm3082 I think, both have 100 MHz 200 MS/s and my DS2072 @300 Mhz
I try to measure current, voltage and multiply both to see the power
on all 3 DSOs all channels and math are set to RMS.
But only the Rigol shows a 10-20W different calculated value
the math also changes with V/div resolution on the Rigol, that doesn't happen on the other 2 DSOs
Am I doing something wrong? all 3 DSO are set the same way, very odd ...
(btw, I really hate that the Rigol switches off/restarts after self cal and IIRC it also forgets the settings I made before self cal)
I want to use the Rigol because of it's better handling and ways to measure ...
