Title: Rigol DS2000A display freeze on manual memory depth.
Post by: npelov on October 13, 2016, 11:19:51 am
I recently updated firmware (see attachment) of my Rigol DS2072A, hoping that some of the bugs will be fixed. I noticed that If I set the memory depth to manual the display freezes at certain time bases (). The display shows last waveform, but the UI is still responsive. If I move the signal or move the trigger, the trigger state doesn't update on screen. Also single works fine. With auto memory depth the display is updated as it should. Did I mess something up or it's a bug? Can I downgrade?

Also I have the feeling that screen is updating too slow - like 3-4 times/s even with auto memory depth. At 5us/div the screen update should be relatively fast.

Did anyone else had the same problem?

P.S.
I haven't tried reset to defaults. I'll do that now.

Well, I messed up  |O !!! I've set trigger holdoff to a quite big number because I had troubles triggering on digital data and I forgot about it. I set "startup" to "default", rebooted and it worked fine, and I remembered what what did.

Does anyone know how to reset everything to default without rebooting the scope?

Connect the probe to the calibration signal and press "Auto"?  :popcorn:

Yes, that removes the holdoff and other trigger settings. It doesn't reset everything, but it'll probably fix most of the stuff I can mess up.
