[:SOURce]:POWer:LIMit[:AMPLitude] -144 to + 16 dBm
The command limits the maximum Rf output level in operating mode CW and SWEEP. It does not
influence the display LEVEL and the answer to query POW?.
Example: :SOUR:POW:LIM:AMPL 15 *RST value is +16 dBm
[:SOURce]:POWer:MANual -144 to +16 dBm
The command sets the level if SOURce:POWer:MODE is set to SWEep and
SOURce:SWEep:MODE to MANual. Only level values between START and STOP are permissible.
(As to specified range, cf. :POWer). *RST value is -30 dBm
Example: :SOUR:POW:MAN 1dBm
[:SOURce]:POWer:MODE FIXed | SWEep | LIST
The command specifies the operating mode and thus also by means of which commands the
level setting is checked.
FIXed The output level is specified by means of commands under :SOURce:
POWer:LEVel.
SWEep The instrument operates in the SWEep mode. The level is specified by means of
:SOURce:POWer;STARt; STOP; CENTer; SPAN and MANual.
LIST The instrument processes a list of frequency and level settings. The settings are
effected in the SOURce:LIST subsystem.
Setting :SOURce:POWer:MODE LIST automatically sets command :SOURce
:FREQuency :MODE to LIST as well. *RST value is FIXed
Example: :SOUR:POW:MODE FIX
[:SOURce]:POWer:STARt -144 to +16 dBm
The command sets the starting value for a level sweep. STARt may be larger than STOP, then
the sweep runs from the high to the low level (As to specified range, cf. :POWer:AMPLitude).
Example: :SOUR:POW:STAR -20 *RST value is -30dBm
[:SOURce]:POWer:STOP -144 to +16 dBm
The command sets the final value for a level sweep. STOP may be smaller than STARt. (As to
specified range, cf. :POWer:AMPLitude). *RST value is -10dBm
Example: :SOUR:POW:STOP 3
[:SOURce]:POWer:STEP[:INCRement] 0.1 to 10 dB
The command sets the step width with the level setting if UP and DOWN are used as level values.
The command is coupled with KNOB STEP in the manual control, i.e., it also specifies the step
width of the shaft encoder.
Only dB is permissible as a unit here, the linear units (V, W etc.) are not permitted.
Example: :SOUR:POW:STEP:INCR 2 *RST value is 1dB
