Falling edge trigger
Delay
The Delay trigger works in tandem with the edge
trigger, by waiting for a specified time(duration) or
number of events before the edge trigger starts.
This method allows pinpointing a location in a long
series of trigger events.
Note: when using the delay trigger, the edge
trigger source can be any one of the channel
inputs, the EXT input or the AC line.

Pulse Width
(glitch)
Triggers when the pulse width (glitch) of the signal
is less than, equal, not equal or greater than a
specified pulse width (glitch).
Pulse width
Video
Extracts a sync pulse from a video format signal,
and triggers on a specific line or field.
Pulse and Runt
Triggers on a “runt”. A runt is a pulse that passes a
specified threshold but fails to pass a second
threshold. Both positive and negative runts can be
detected.
