Smart

This trigger group sets conditions on signals with rare features.

INDOW

A trigger occurs when a signal enters or exits a window defined
by adjustable thresholds.

NTERVAL

While Glitch trigger performs over the width of a pulse, Interval
trigger performs over the width of an interval: the signal
duration (the period) separating two consecutive edges of the

same polarity, positive to positive or negative to negative. Use interval
trigger to capture intervals that fall short of, or exceed, a given time limit. In
addition, you can define a width range to capture any interval that is itself
inside or outside the specified range (an Exclusion trigger by interval).

LITCH

Glitch trigger is a simpler form of Width trigger. Use Glitch
trigger when you want to define a fixed pulse-width time or
time range only. Glitch trigger makes no provision for voltage

levels or ranges.

ROPOUT

Used primarily in single-shot applications, and usually with a
pre-trigger delay, Dropout trigger can detect lost signals. The
trigger is generated at the end of the timeout period following

the last trigger source transition.

UNT

The Runt trigger occurs when a pulse crosses a first threshold
line, but fails to cross a second threshold line before re-crossing
the first. Other defining conditions for this trigger are the edge

(triggers on the slope opposite to that selected) and runt width.

LEW

ATE

SlewRate trigger activates a trigger when the rising or falling
edge of a pulse crosses two threshold levels: an upper level and
a lower level. The pulse edge must cross the thresholds faster or

slower than a selected period of time.
