SOURce<1|2>:POWer[:LEVel][:IMMediate][:AMPLitude] <numeric_value>
This command defines the output level of the tracking generator in the current measurement window.
This command is only valid in conjunction with the tracking generator option B9.
Parameter: <numeric value>::= -30 dBm to 5 dBm. (-100 dBm to + 5dBm with option B12)
Example:
"SOUR:POW -20dBm"
'Sets the tracking generator level in screen A to -20 dBm.
Characteristics: *RST value: -20 dBm
SCPI: conforming
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 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: conforming
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 analyzer is set in 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

SOURce<1|2>:POWer:STARt -30 dBm to 0 dBm
This command defines the start power of the power sweep. start power can be set between -30 dBm and
+5 dBm for the R&S FSQ. With the option FSU-B12 the power can be set between -100 and + 5 dBm.
Example:
"SOUR:POW:STAR –20dBm"
'sets the start level to –20 dBm in screen A.
Characteristics: *RST-Wert: - 30 dBm
SCPI: conforming
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 +5 dBm for the R&S FSQ. With the option FSU-B12 the power can be set between -100
and + 5 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
