The edge trigger is the simplest trigger type. An
edge trigger triggers when the signal crosses an
amplitude threshold with either a positive or
negative slope.
The Delay trigger works in tandem with the edge
trigger, by waiting for a specified time (duration)
or number of events before the delay 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. *EXT only available on 2 channel
models.
