Set it to:
1) DC coupled (AC does not go low enough)
2) 50 ohms if your driving source will tolerate it, otherwise 1 meg ohm.
3) Manual trigger mode (Auto is to fast and it forgets where the trigger should
4) Trigger level around 1/2 the PPS P-P voltage
Once set up that way, the triggering should be pretty solid. There is still the
wonderful stuff about pulses that
arrive on top of each other ….
