I would like to share my expireinces

  872   Mon Mar 7 08:45:32 2022 Stefan RittWhy does not trigger at higher sampling frequencies?Unfortunately I have not idea what the
problem could be. In principle the trigger
should be independent of the sampling speed,

Did anyone have a "missing
sliders problem" in GUI (see attachment)

which requires a minimum pulse width of 3-4
ns. I see that your pulses are only 1-2 ns

Thanks a lot.

I solved it.

you, that helps a lot!
