Trigger
The trigger configures the conditions for when the MDO-2000A
SERIES captures a waveform.
Trigger Type Overview
Edge
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.
Rising edge trigger
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 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 is only available on 2 channel models.
