[:SOURce]:BB:IMPairment:IQOutput<ch>:LEAKage:I
[:SOURce]:BB:IMPairment:IQOutput<ch>:LEAKage:Q
[:SOURce<hw>]:BB:IMPairment:DELay <Delay>
Sets the time delay of both I and Q vectors relative to the selected trigger and marker
or relative to the other instrument(s) working in the master-slave synchronous
mode.section .
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>
Example:
Manual operation:
[:SOURce<hw>]:BB:IMPairment:IQRatio[:MAGNitude] <IqRatio>
This command sets the ratio of I modulation to Q modulation (amplification "imbal-
ance"). The input may be either in dB or %. The resolution is 0.001 dB, an input in per-
cent is rounded to the closest valid value in dB. A query returns the value in dB.
Parameters:
<IqRatio>
Example:
Manual operation:
[:SOURce<hw>]:BB:IMPairment:LEAKage:I <I>
This command sets the carrier leakage amplitude for the I-signal component.
