Rigol DG800 burst/sweep wont trigger on external signal
« on: May 06, 2024, 08:06:39 am »
Hi,

i tried using the ext trigger input, but i cant get it to work. But i could get FM modulation to work, so i think there is no issue on the "outside" of the device.
Using the manual trigger, it works.

Anyone else had issues here?

On mine, it's working perfectly well. I used Ch2 to trigger Ch1, arbitrary burst. I found the Ext. trigger threshold to be approx. 1.6V with a hysteresis of round about 120mV.

I'm using firmware 02.05.00.00 on mine since the later firmware 02.06.00.01 broke the selection menus for arbitrary waveforms (and Rigol specified the reduced set of built-in arbitraries in their latest user's guide, p.52, so it's not a bug but a feature...  :palm: ).

I don't know if the firmware also causes your difficulties to get the external trigger input running. I didn't update mine for testing.
