Settings panel (Rise/Fall Time Trigger configuration menu) fields and controls
Field or control Description
Source
Lists the source channel or waveform to use to trigger.
Trigger When
• < Limit: A signal has a rise/fall time less than the specified time limit.
• > Limit: A signal has a rise/fall time greater than the specified time limit.
• = Limit: A signal has a rise/fall time that is equal to the specified time limit (±5%).
• ≠Limit: A signal has a rise/fall time that does not equal (is greater than or less than) the specified
time limit (±5%).
Time Limit Sets the time period condition to be met.
Slope Sets the signal transition direction to detect. (rising, falling, or either direction).
Upper Threshold
Sets the upper amplitude level through which the signal must pass to be considered a valid transition.
Lower Threshold
Sets the lower amplitude level through which the signal must pass to be considered a valid transition.
Mode & Holdoff
Trigger Mode determines how the instrument behaves in the absence or presence of a trigger event.
Holdof
f sets the amount of time the oscilloscope waits after a trigger event before detecting and
triggering on the next trigger event.
For additional information on Trigger Mode, Holdoff, forcing a trigger, and the Trigger Frequency
Counter see Mode and Holdoff panel on page 226.
Act On Trigger
Set the actions the instrument takes when a trigger event occurs.
For additional information on the Act On Trigger panel see Act On Trigger configuration
menu on page 227.

Runt Trigger configuration menu
Use the Runt trigger to trigger on waveforms where a low amplitude pulse crosses one threshold but fails to cross a second threshold
before recrossing the first.
To open the Runt trigger configuration menu:
1. Double-tap the Trigger badge on the Settings bar.
