R&S FSP Remote Control – Description of Commands
SOURce Subsystem
SOURce<1|2>:POWer[:LEVel][:IMMediate]:OFFSet -200dB to +200dB
This command defines a level offset for the tracking generator level. Thus, for example, attenuators or
amplifiers at the output of the tracking generator can be taken into account for the setting.
This command is only valid in conjunction with the tracking generator option R&S FSP-B9.
Example:
"SOUR:POW:OFFS -10dB"
'Sets the level offset of the tracking generator in screen A to - 20 dBm.
Characteristics: *RST value: 0dB
SCPI: conform
Mode: A
SOURce<1|2>:POWer:MODE FIXed | SWEep
This command activates or deactivates the power sweep. If the power sweep is ON the enhancement
label TGPWR is shown and the R&S FSP is set to zero span mode (span = 0Hz). During the sweep
time of the zero span the power at the internal tracking generator is changed linear from start power
to stop power. The start and stop power values are shown on the right side below the diagram
Example:
"SOUR:POW:MODE SWE"
''switches on the level sweep in screen A.
Characteristics: *RST value: FIX
SCPI: conform
Mode: A
SOURce<1|2>:POWer:STARt -30 dBm to 0 dBm
This command defines the start power of the power sweep. The start value can be smaller than the
start value.
The start power can be set between -30 dBm and +0 dBm.
Example:
"SOUR:POW:STAR 0dBm"
'sets the end level to 0 dBm in screen A.
Characteristics: *RST value: 0 dBm
SCPI: conform
Mode: A
SOURce<1|2>:POWer:STOP -30 dBm to 0 dBm
This command defines the stop power of the power sweep. The stop power can be set between -30
dBm and +0 dBm.
The stop value can be smaller than the start value.
Example:
"SOUR:POW:STOP 0dBm"
'sets the end level to 0 dBm in screen A.
Characteristics: *RST value: 0 dBm
SCPI: conform
Mode: A
