[: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.
Manual operation: See "State - Digital Impairments" on page 306
[:SOURce<hw>]:BB:IMPairment:OPTimization:MODE <Mode>
This command sets the optimization mode.
Parameters:
<Mode> FAST | QHIGh
FAST
Optimization is reached by compensation for I/Q skew.
QHIGh
Optimization is reached by compensation for I/Q skew and fre-
quency response correction.
*RST: FAST
Example:
BB:IMP:OPT:MODE FAST
sets the optimization mode Fast.
Manual operation: See "Optimization Mode - Digital Impairments" on page 307
[:SOURce<hw>]:BB:IMPairment:OPTimization:STATe <State>

lator.
Parameters:
<State> 0 | 1 | OFF | ON
*RST: 1
Example:
BB:IMP:OPT:STAT ON
activates internal compensation of signal distortions.
