SCPI command:
[:SOURce<hw>]:BB:IMPairment:QUADrature[:ANGLe] on page 667
Internal Compensation
"Internal compensation" of signal distortions "of the RF output "can be activated / deac-
tivated.
Optimize internal IQ-Impairments for RF Output - Digital Impairments
Activates or deactivates internal compensation of signal distortions of the RF output.
Signal distortions can be either optimized for the RF output (active) or for the differential
I/Q output (not active).
SCPI command:
[:SOURce<hw>]:BB:IMPairment:OPTimization:STATe on page 661
Optimization Mode - Digital Impairments
Selects the optimization mode.
"Fast"
Optimization is reached by compensation for I/Q skew.
"High Quality"
Optimization is reached by compensation for I/Q skew and frequency
response correction.
