"Auto"
Sets an automatically repeated sweep cycle.
Example:
SOUR:SWE:POW:MODE AUTO
TRIG:PSW:SOUR AUTO
SOUR:POW:MODE SWE
"Single"
Sets a single sweep cycle. The sweep is triggered by the "Execute Sin-
gle Sweep" button, or by means remote trigger commands, e.g. *TRG.
Example:
SOUR:SWE:POW:MODE AUTO
TRIG:PSW:SOUR SING
SOUR:POW:MODE SWE
SOUR:SWE:POW:EXEC
"Step"
Sets a step-by-step sweep cycle.
If this mode is activated, the cursor moves to the value displayed for
"Current Level". Each sweep step is triggered by a variation of the value
in the "Current Level" entry window. The step width is set below at entry
field "Step".
If this mode is activated, the cursor moves to the value displayed for
"Current Level". If a different sweep mode was activated prior to the
"Step" mode, the current sweep is stopped. The step sweep starts at
the current level value.
Example:
SOUR:SWE:POW:MODE MAN
SOUR:SWE:POW:STEP 0.5
SOUR:POW:MODE SWE
SOUR:POW:MAN -16
The value entered with command SOUR:SWE:POW:STEP sets the step
width.
The value entered with command SOUR:POW:MAN has no effect, the
command only triggers the next sweep step. However, the value has to
be in the currently set sweep range (start to stop). In remote control only
a step-by-step sweep from start to stop frequency is possible.
"Extern Single"
Sets a single sweep cycle. The sweep is triggered by an external trigger
signal.
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:POW:MODE AUTO
TRIG:PSW:SOUR EXT
SOUR:POW:MODE SWE (External trigger)
