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
TRI:PSW:SOUR SING
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 con-
trol only a step-by-step sweep from start to stop frequency is possi-
ble.
