Test Equipment / Re: SDS800X HD - Issue disscusions - is it me, or the scope?
« Last post by ebastler on Today at 07:20:54 am »I just gave the Qualified trigger a quick try and cannot reproduce your issue so far.
Using 0V .. 3V pulses on both, the Qualified and Edge channel, I can happily overdrive the channels at 100 mV/div and higher sensitivity. Qualified trigger remains stable for me. Please provide further details on your setup and signals.
One caveat: In Qualified trigger mode, pushing the trigger threshold encoder has a different function than normally. It does not set a default (halfway) threshold, but toggles the threshold knob between controlling the Qualified and Edge channels. Did you possibly set unintended threshold values due to that?
