Command Syntax
Description
[SOURce]:POWer:ALC:SOURce
INTernal|DIODe|PMETer|DPOSitive
Selects the source of the feedback signal for the ALC. The
DIODe parameter assumes a negative crystal detector is
used. DPOSitive allows for the use of a positive crystal
detector.
[SOURce:]POWer:ALC:SOURce?
Queries the type of leveling for output power automatic
level control
[SOURce:]POWer:ATTenuation:AUTO?
Queries attenuation mode: auto or manual
[SOURce:]POWer:CENTer d
Sets the center of power
[SOURce:]POWer:CENTer?
Queries the center of power
[SOURce:]POWer[:LEVel][:IMMediate][:A
MPLitude:]STEP[:INCRement] d (DB)
Selects the increment value for the Synthesizer output
power level
[SOURce:]POWer[:LEVel][:IMMediate][:A
MPLitude:]STEP[:INCRement]?
Query the increment value for the Synthesizer output
power level

Description
[SOURce]:CORRection:LOSS <offset> [DB]
Sets the power offset to the value specified by <offset>. The
units are dB.
[SOURce]:CORRection:LOSS?
Queries the power offset. The value returned is in dB.
[SOURce]:CORRection:SLOPe <slope>
Sets the power slope to the value specified by <slope>. The
units are dB/GHz.
[SOURce]:CORRection:SLOPe?
Queries the power slope. The value returned is in dB/GHz
