External Trigger Type
Last updated: May 24, 2006
External trigger type selects the trigger that is routed to the rear panel
TRIG OUT
port (see
Rear Panel Connectors
). The triggers are based off of the internal clocks/references of the test set and are the same signals that are used to trigger the measurements and data connection processing functionality.
