587Operating Manual 1407.6062.32 ─ 08
A positive value means that the I and Q vectors delay relative to the marker/trigger or to
the other instrument and vice versa.
Parameters:
<Delay> float
Range: -500E-9 to 500E-9
Increment: 1E-12
*RST: 0
Example:
BB:IMP:DEL 32.0E-9
sets the I/Q delay
[:SOURce<hw>]:BB:IMPairment:IQRatio <IqRatio>
This command sets the ratio of I modulation to Q modulation (amplification “imbalance”).
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
Example:
BB:IMP:IQR 3 PCT
sets the imbalance to 3 percent.
BB:IMP:IQR?
queries the imbalance.
Response: 0.259000
the value is returned in dB
BB:IMP:IQR 1
sets the imbalance to 1 dB.
[:SOURce<hw>]:BB:IMPairment:LEAKage:I <I>
This command sets the carrier leakage amplitude for the I-signal component.
Parameters:
<I> float
Range: -10 to 10
Increment: 0.01
*RST: 0
Default unit: PCT
Example:
BB:IMP:LEAK:I 3 PCT
sets the leakage for the I-component to 3 percent.
[:SOURce<hw>]:BB:IMPairment:LEAKage:Q <Q>
This command sets the carrier leakage amplitude for the Q-signal component.
