TV
TV triggers provide stable triggering on standard or custom composite
video signals. Use them on PAL, SECAM, or NTSC systems. Support for
HDTV triggering on 1080i, 1080p, and 720p formats is included. Use
CUSTOM setup for other standards.

SMART Triggers
SMART Triggers are defined as follows:
Glitch
Glitch trigger is a simpler form of Width trigger. Use Glitch trigger for
defining only fixed pulse-width times or time ranges. Glitch trigger
makes no provision for voltage levels or ranges.
defining only fixed pulse-width times or time ranges. Glitch trigger
makes no provision for voltage levels or ranges.
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 falling short of or exceeding 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, i.e. it can be used as an Exclusion trigger by
interval.

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. You can select a timeout period from 2 ns to 20 s,

transition. You can select a timeout period from 2 ns to 20 s,
Runt
The runt trigger is programmed to occur when a pulse crosses a first
threshold line and fails to cross a second threshold line before
recrossing the first. You can select both voltage thresholds within a time
range of 100 ps to 20 s. Other defining conditions for this trigger are the
edge (triggers on the slope opposite to that selected) and runt width.

Slew Rate
Slew rate 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. You can select both thresholds within a range of 2 ns to
20 s.
