11.14.10 SOURce:IQ Subsystem

This subsystem contains the commands for checking the I/Q modulation.
[:SOURce]:IQ:CREStfactor
[:SOURce]:IQ:IMPairment:IQRatio[:MAGNitude]
[:SOURce]:IQ:IMPairment:LEAKage:I
[:SOURce]:IQ:IMPairment:LEAKage:Q
[:SOURce]:IQ:IMPairment:QUADrature[:ANGLe]
[:SOURce]:IQ:IMPairment[:STATe]
[:SOURce]:IQ:IMPairment:SWAP[:STATe]
[:SOURce]:IQ:STATe
[:SOURce]:IQ:SOURce
[:SOURce<hw>]:IQ:SWAP[:STATe]
[:SOURce]:IQ:WBSTate
[:SOURce]:IQ:CREStfactor <CrestFactor>
Sets the crest factor of the IQ modulation signal.
Parameters:
<CrestFactor>
Manual operation:
[:SOURce]:IQ:IMPairment:IQRatio[:MAGNitude] <IqRatio>
Sets the ratio of I modulation to Q modulation (amplification "imbalance"). The input
may be either in dB or %. The resolution is 0.001 dB, an input in percent is rounded to
the closest valid value in dB. A query returns the value in dB.
Parameters:
<IqRatio>
Manual operation:
[:SOURce]:IQ:IMPairment:LEAKage:I <I>
[:SOURce]:IQ:IMPairment:LEAKage:Q <Q>
Sets the carrier leakage amplitude for the Q-signal component.
