Set Trigger Holdoff
Trigger Holdoff sets the time, after triggering on an event, that the instrument waits before detecting the same trigger event to
start the next acquisition.
Setting the correct holdoff time is important to get a stable trigger. The longer holdoff time for the top waveform causes unstable
triggering. The shorter holdoff set for the bottom waveform only triggers on the first pulse in the burst to remedy the unstable
trigger.
Prerequisite: You have set up a trigger event for a signal.
1. Double-tap the Trigger badge on the Settings bar to open the Trigger configuration menu.
2. Tap the Mode & Holdoff panel.
3. To set a specific holdoff time, tap Time, then tap Holdoff Time and use the assigned multipurpose knob to specify a holdoff
time. Or double-tap the field and use the virtual keypad to enter a holdoff time.
4. To delay the trigger a random amount of time between triggers, tap Random.
