Interval Trigger Whereas Glitch Trigger performs over the width of a pulse,
Interval Trigger (Fig. 8–9) performs over the width of an
interval. An interval corresponds to the signal duration
separating two consecutive edges of the same polarity. Interval
Trigger is used to capture intervals that are inferior to or exceeding
a given time limit. In addition, a width range can be defined to
capture any interval that is comprised within or outside the specified
range — an Exclusion Trigger by Interval.

Applications Interval Trigger is helpful for determining missing cycles or
transitions, and for ignoring unwanted signal reflections.
