[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude] -1
40 dBm to P
max
(+29 dBm with R&S SML-B10)
The command sets the RF output level in operating mode CW. UP and DOWN can be indicated
in addition to numeric values. Then the level is increased or reduced by the value indicated under
[:SOUR]:POW:STEP.
In this command, the OFFSet value is considered. Thus the specified range indicated is only valid
for
:
SOUR:POW:OFFS 0.
The keywords of this command are optional to a large extent, thus the long as well as the short
form of the command is shown in the example.
Example: :SOUR:POW:LEV:IMM:AMPL -10 or
:POW –10 *RST value is -30 dBm
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude]:OFFSet -100 to +100 dB
The command enters the constant level offset of a series-connected attenuator/ amplifier (cf.
Chapter 4, Section "Level Offset"). If a level offset is entered, the level entered using :POW does
no longer conform to the RF output level. The following relation is true:
:POW = RF output level +
:
POW:OFFS
Entering a level offset does not change the RF output level but only the value queried by :POW.
The level offset is also valid for level sweep!
Only dB is permissible as a unit here, linear units (V, W etc.) are not permitted.
Example: :SOUR:POW:LEV:IMM:AMPL:OFFS 0 or
:POW:OFFS 0 *RST value is 0 dB
[:SOURce]:POWer:LIMit[:AMPLitude] -140 dBm to P
max
(+29 dBm with R&S SML-B10)
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 19 not influenced by *RST
[:SOURce]:POWer:MANual -140 dBm to P
max
(+29 dBm with R&S SML-B10)
The command sets the level if SOUR:POW:MODE is set to :SWE and SOUR:SWE:MODE to MAN.
Only level values between STARt and STOP are permitted (as to specified range, cf.
:
POW:AMPL).
Example: :SOUR:POW:MAN 1dBm *RST value is -30 dBm
[:SOURce]:POWer:MODE CW | FIXed | SWEep
The command specifies the operating mode and thus also by means of which commands the
level setting is checked.
CW | FIXed The output level is specified by means of commands under [:SOUR]:POW:LEV.
SWEep The instrument operates in the SWEep mode. The level is specified by means of
[:SOUR]:POW; STAR; STOP; CENT; SPAN and MAN.
Example: :SOUR:POW:MODE FIX *RST value is FIX
[:SOURce]:POWer:RCL INCLude | EXCLude
INCLude The stored RF level is loaded too when instrument settings are loaded.
EXCLude The stored RF level is not loaded when instrument settings are loaded ie the current
level setting is maintained.
Example: :SOUR:POW:RCL INCL not influenced by *RST
