671 Operating Manual 1403.7458.32 ─ 14
Example: BB:IMP:QUAD:ANGL -5DEG
sets the quadrature offset to -5 degrees.
Manual operation: See "Quadrature Offset - Digital Impairments" on page 292
[: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 292
[: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 293
[:SOURce<hw>]:BB:IMPairment:OPTimization:STATe <State>
Activates and deactivates internal compensation of signal distortions by the I/Q modu-
lator.
Parameters:
<State> 0 | 1 | OFF | ON
Example: BB:IMP:OPT:STAT ON
activates internal compensation of signal distortions.
Manual operation: See "Optimize internal IQ-Impairments for RF Output - Digital
Impairments" on page 292
