Overview
The E4990A has one trigger source. When this trigger source detects a
trigger signal that has occurred, a sweep or point measurement is
performed for channels.
The execution of measurement for each channel does not depend on
whether the channel is displayed. Channels that have been activated can
be measured even if they are not displayed.
For each channel, a sweep is performed only for the stimulus ports
required to update the parameters of the displayed trace.
Selecting a Method to Start Measurement (Trigger Source)
The trigger source generates a cue signal that initiates a measurement
process. Four types of trigger sources are available:
