"Extern Start/
Stop"
Sets an automaticly repeated sweep cycle that is started, stopped and
restartet by subsequent external trigger events.
The first external trigger signal starts the sweep (Start).
The next external trigger signal stops the sweep at the current frequency
(Stop).
The third external trigger signal starts the sweep at the start frequency
(Start).
If a different sweep mode was activated prior to the "Extern Start/Stop"
mode, the current sweep is stopped and the "Extern Start/Stop" sweep
starts at the start frequency when triggered.
The "Reset" button resets the sweep to the start frequency.
The external trigger signal is input at the rear of the instrument (BNC
connector INST TRIG).
