External Trigger (EXT TRIGGER)

Triggers on a negative lTL transition or contact closure to ground.
This connector outputs a Tl'L signal which can be programmed by the user in a test sequence
to be high or low. By default, this output provides an end-of-sweep 'ITL signal (for use with
part handlers).
