[:SOURce]:BB:IMPairment:IQOutput<ch>:IQRatio[:MAGNitude] <IqRatio>
Sets the ratio of I modulation to Q modulation (amplification imbalance) of the corre-
sponding digital I/Q channel. 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]:BB:IMPairment:IQOutput<ch>:SKEW <Skew>
Sets a delay between the Q vector and the I vector of the corresponding stream.
Parameters:
<Skew>
Manual operation:
[:SOURce]:BB:IMPairment:IQOutput<ch>:LEAKage:I <I>
[:SOURce]:BB:IMPairment:IQOutput<ch>:LEAKage:Q <Q>
Determines the leakage amplitude of the I or Q-signal component of the corresponding
stream.
Parameters:
<Q>
