"Extern Step"
Sets a step-by-step sweep cycle. Each sweep step is triggered by an
external trigger signal (trigger source as described under "Extern Sin-
gle"). The step width corresponds to the step width of the rotary knob.
If a different sweep mode was activated prior to the "Extern Step" mode,
the current sweep is stopped. The "Extern Step" sweep always starts
at the start level.
The "Reset Sweep" button resets the sweep to the start level.
Example:
SOUR:SWE:POW:MODE STEP
SOUR:SWE:POW:STEP 0.5
TRIG:PSW:SOUR EXT
SOUR:POW:MODE SWE (External trigger)
"Extern Start/
Stop"
Sets an automatically 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 fre-
quency (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 level.
Refer to the description of the rear panel for information about the con-
nectors for external trigger signal input (see chapter 2.2, "Rear Panel
Tour", on page 25).
