The instrument operates at a constant level. CW and FIXed are synonyms.
The output level is set with :SOURce:POWer.
SWEep
The instrument operates in SWEep mode. The level is set using the

[SOURce:]POWer:STARt Minimum level ... Maximum level
The command sets the RF start level in Sweep mode.
As with the Level value entered in the RF Level menu, the OFFSet value is also taken into
consideration with this command.
The specified value range is therefore only effective if :SOURce:POWer:OFFSet is set to 0. The
value range for other OFFset values can be calculated using the following formula:
Minimum level + OFFSet ...Maximum level + OFFSet
Parameters: Minimum level ... Maximum level
The value range for the level setting varies according to the instrument model.
The values are given in the data sheet.
Example:
POW:STAR -20 dBm
'sets the start level for the level sweep to -15 dBm.

[SOURce:]POWer:STEP[:INCRement] 0 dB ... 100dB
The command sets the step width for the level setting if UP and DOWN are used as the level values
and variation mode :SOUR:POW:STEP:MODE USER is selected. The command is linked to setting
Variation Step for manual control, i.e. the command also sets the step width of the rotary knob for
Variation Active on.
Example:
SOURce:POWer:STEP:INCRement 2 or POW:STEP 2
'sets the step width for entering the RF level to 2 dB.
