R&S SGT100A
A positive I/Q skew means that the Q vector delays relative to the I vector and vice
versa.
Parameters:
<Skew>
Example:
Manual operation:
[:SOURce<hw>]:BB:IMPairment:STATe <State>
The command activates (ON) and deactivates (OFF) the three impairment or correc-
tion values LEAKage, QUADrature and IQRatio for the digital baseband signal prior to
input into the I/Q modulator.
Parameters:
<State>
Example:
Manual operation:
[:SOURce<hw>]:BB:IMPairment:OPTimization:MODE <Mode>
This command sets the optimization mode.
Parameters:
<Mode>
