Mode & Holdoff panel (Bus Trigger configuration panel) fields and controls
Field or control Description
Trigger Mode The trigger mode determines how the instrument behaves in the absence or presence of a trigger
event:
Auto trigger mode enables the instrument to acquire and display a waveform even if a trigger does not
occur
. Auto mode uses a timer that starts when the acquisition is started, and the pretrigger information
is obtained. If a trigger event is not detected before the timer times out, the instrument forces a trigger.
The length of time it waits for a trigger event depends on the time base setting.
Normal trigger mode enables the instrument to acquire a waveform only when it is triggered. If no
trigger occurs, the last waveform record acquired remains on the display. If no last waveform exists, no
waveform is displayed.
Force Trigger Forces a trigger event regardless of whether the waveform meets any trigger conditions.
Holdoff Time Tap the Holdoff Time field and use the multipurpose knob to adjust the holdoff time value. Or
double-tap the field and use the virtual keypad to enter a time holdoff period. Trigger holdoff sets the
amount of time the oscilloscope waits after a trigger event before detecting and triggering on the next
trigger event. Use this option when the signal that you want to trigger on has several possible trigger
points or is a burst signal.
Act on Trigger Tap the Act on Trigger button to configure the actions the instrument must take when a trigger event
occurs.
See Act On Event configuration menu on page 105 for the available fields and controls.
