[: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> float
Range:
-1 to 1
Increment: 1E-4
*RST:
0
Manual operation: See "Gain Imbalance" on page 140
[:SOURce]:BB:IMPairment:IQOutput<ch>:SKEW <Skew>
Sets a delay between the Q vector and the I vector of the corresponding stream.
Parameters:
<Skew> float
Range:
-500E-9 to 500E-9
Increment: 1E-12
*RST:
0
Manual operation: See "Skew " on page 141
[: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> float
Range:
-10 to 10
Increment: 0.01
*RST:
0
Manual operation: See "I/Q Offset" on page 140

In the R&S SGT, some calculation processes take longer time. While operating the
instrument manually, you can observe the status of an initiated process by the busy
indicator. The following commands fulfill the same task in the remote control operation.
