SOURce:DM Subsystem (R&S SMV03)
This subsystem contains the commands to control the vector modulation and to set the parameters of
the modulation signal.

[:SOURce]:DM:IMPairment[:STATe] ON | OFF
The command activates (ON) or deactivates (OFF) the three tuning or correction values
LEAKage, QUADrature and IQRatio for vector modulation.
Example: :SOUR:DM:IMP ON *RST value is OFF
[:SOURce]:DM:IQ:CRESTfactor?
The command ask the crestfactor.
Example: :SOUR:DM:IQ:CREST?
[:SOURce]:DM:IQ:CRESTfactor <numeric> [ DB ] | MAXimum | MINimum
The command adjusts the crestfactor.
Example: :SOUR:DM:IQ:CRES 10DB *RST-Wert 0
[:SOURce]:DM:IQ[:STATe] ON | OFF
The command switches the vector modulation on or off,
Example: :SOUR:DM:IQ:STAT ON *RST value is OFF
[:SOURce]:DM:IQRatio:[MAGNitude] -12.0 to 12.0 PCT
The command adjusts the ratio of I and Q modulation (gain balance).
Example: :SOUR:DM:IQR:MAGN -5 PCT *RST value is 0
