"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 is set below at entry field "Step Lin" or "Step
Log".
Example:
SOUR:SWE:FREQ:MODE STEP
SOUR:SWE:FREQ:SPAC LIN
SOUR:SWE:FREQ:STEP:LIN 1MHz
TRIG:FSW:SOUR EXT
SOUR:FREQ: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).
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 21).
Example:
SOUR:SWE:FREQ:MODE AUTO
TRIG:FSW:SOUR EAUT
SOUR:FREQ:MODE SWE (External trigger)
