3.6.4 REMOTE TRIGGERING OF SWEEP TIME CI RCUIT
The Sweep Time Circuit can be remotely triggered by apply-
ing a10 volt positive pulse to pin 7 of the REMOTE plug.
For proper operation, the Front Panel SWEEP TIME
Selector must be set for one of the four variable sweep
time positions, and the TRIG/RECUR Switch set to the
TR I G position. The repetition rate of the external trigger
should be slower than the frequency running rate set by the
Front Panel SWEEP TIME Selector and VAR/MANUAL
