[:SOURce<hw>]:IQ:IMPairment:IQRatio[:MAGNitude] <Magnitude>
[:SOURce]:BB:IMPairment:IQOutput<ch>:IQRatio[:MAGNitude] <IqRatio>
[:SOURce]:BB:IMPairment:RF<ch>:IQRatio[:MAGNitude] <IqRatio>
Sets the ratio of I modulation to Q modulation (amplification imbalance) of the corre-
sponding digital channel.
Table 12-3: Value range
Impairments Min [dB] Max [dB] Resolution
Digital -4 4 0.0001
Analog -1 1 0.0001
Parameters:
<IqRatio> float
The setting value can be either in dB or %. An input in percent is
rounded to the closest valid value in dB.
Range:
-4 to 4
Increment: 1E-4
*RST:
0
Default unit: dB | PCT (setting command) / dB (result value)
Example:
SOURce:BB:IMPairment:RF1:IQRatio:MAGNitude 10 PCT
SOURce:BB:IMPairment:RF1:IQRatio:MAGNitude?
// 0.848
// the value is returned in dB
Manual operation: See "Gain Imbalance" on page 273
