WINDOW
A smart trigger occurs when a signal enters or exits a window defined by
adjustable thresholds.
INTERVAL
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.
GLITCH
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.
DROPOUT
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.
