User Manual 1176.8674.02 ─ 07
A positive I/Q skew means that the Q vector delays relative to the I vector and vice
versa.
Parameters:
<Skew>
float
Range:
-500E-9 to 500E-9
Increment: 1E-12
*RST:
0
Example:
BB:IMP:SKEW 410.0E-9
sets the I/Q skew.
Manual operation:
See
[: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>
0 | 1 | OFF | ON
*RST:
0
Example:
BB:IMP:STAT OFF
deactivates digital impairment.

QHIGh
Optimization is reached by compensation for I/Q skew and fre-
quency response correction.
*RST:
