Example: IQ:GAIN DB0
sets gain 0 dB (standard).
Manual operation: See "Baseband Gain-Gain - I/Q Mod" on page 287
[:SOURce<hw>]:IQ:IMPairment:IQRatio[:MAGNitude] <Magnitude>
This command sets the ratio of I modulation to Q modulation (amplification “imbal-
ance”).
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.
Manual operation: See "Gain Imbalance - I/Q Mod" on page 285
[:SOURce<hw>]:IQ:IMPairment:LEAKage:I <I>
Sets the carrier offset for the I-channel of the I/Q modulation.
Parameters:
<I> float
Range:
-10 to 10
Increment: 0.01
*RST:
0
Default unit: PCT
Example: IQ:IMP:LEAK:I 3 PCT
sets the leakage for the I-channel to 3 percent.
Manual operation: See "Offset - I/Q Mod" on page 285
[:SOURce<hw>]:IQ:IMPairment:LEAKage:Q <Q>
Sets the carrier leakage amplitude for the Q-channel of the I/Q modulation.
Parameters:
<Q> float
Range:
-10 to 10
Increment: 0.01
*RST:
0
Default unit: PCT
Example: IQ:IMP:LEAK:Q 3 PCT
sets the leakage for the Q-channel to 3 percent.
