Example:
IQ:CRES 10
specifies a crest factor of 10 dB for the external analog signal.
[:SOURce<hw>]:IQ:IMPairment:IQRatio[:MAGNitude] <Magnitude>
This command sets the ratio of I modulation to Q modulation (amplification “imbalance”).
Parameters:
<Magnitude> float
Range: -1.0dB to +1.0dB
Increment: 0.005dB
*RST: 0
Default unit: 0dB
Example:
IQ:IMP:IQR 0.5 dB
sets the imbalance.
[:SOURce<hw>]:IQ:IMPairment:LEAKage:I <I>
This command sets the carrier offset for the I-channel of the I/Q modulation.
Parameters:
<I> float
Range: -10 to 10
Increment: 0.02PCT
*RST: 0
Default unit: PCT
Example:
IQ:IMP:LEAK:I 3 PCT
sets the leakage for the I-channel to 3 percent.
[:SOURce<hw>]:IQ:IMPairment:LEAKage:Q <Q>
This command sets the carrier leakage amplitude for the Q-channel of the I/Q modulation.
Parameters:
<Q> float
Range: -10 to 10
Increment: 0.02PCT
*RST: 0PCT
Default unit: PCT
Example:
IQ:IMP:LEAK:Q 3 PCT
sets the leakage for the Q-channel to 3 percent.
[:SOURce<hw>]:IQ:IMPairment:QUADrature:[ANGLe] <Angle>
This command sets the quadrature offset for the I/Q modulation.
