Sorry, I thought you meant 2.5 seconds when I read your post originally. And yes, 2.5 seconds was what it was when I last measured it (3 years ago). When I wrote I "just double-checked" above, I meant I checked this post that I wrote ~3 years ago:

The RigolBildschirmkopie program fails to identify my DS2000 on the USB connection (even though Rigol UltraSigma sees it), so I can't test the speed using that software.

But I'm really not sure what getting a screen print 3 or 4 times a second has to do with the discussion we were having before. It doesn't even approach the 30FPS you claimed might be adequate before. Plus I could get all of the waveform data, plus all of the on-screen parameters - then recreate a DSO screen facsimile on a PC screen - much faster than 4 times a second.

Yes, you are right, has not a lot to do, i was only trying to understand if the DS2072A is slower or fater for screen capture transfer.

The main addition with screen capture over waveform data will be the intensity gradient (as you pointed out previously), if it would be possible to integrate it inside a remote control application like your and obtain something like 10-20 update per second would be great.

RigolBildschirmkopie uses WinUsb, in order to use it with your Rigol you have to use Zadig utility  (http://zadig.akeo.ie/downloads/zadig_2.2.exe) to install the support for it.

I don't know how the screen capture functions on the DS1000Z, but, IIRC, on the DS2000 it either STOPs the DSO - or it seriously slows down the DSO's operation. In other words, it interferes/interrupts the waveform capture rate.

With RigolBildschirmkopie program i get continuous screen capture transfer on pc screen and file write (if enabled) while the scope is running without any evident slow down, until i turn on the math, otherwise i get about3 FPS and i can operate freely the scope panel.

I could/should be the same for DS2000.

I'm afraid just watching the DSO screen would not be enough to test this adequately. You'd have to have the DSO set to a timebase with a very fast update rate that taxes the DSOs resources (e.g. 20ns/div), while having a sufficiently fast changing signal or pulse stream that demonstrates the 30k (or whatever) wfrm/s.
