Positive values mean that the Q vector is amplified more than the I vector by the corre-
sponding percentage. Negative values have the opposite effect.
Remote command:
[:SOURce<hw>]:BB:IMPairment:IQRatio[:MAGNitude]
on page 408
[:SOURce]:BB:IMPairment:IQOutput<ch>:IQRatio[:MAGNitude]

Quadrature Offset
Sets the quadrature offset (see Chapter 7.3.2.3, "Quadrature Offset" , on page 134).
Remote command:
[:SOURce<hw>]:BB:IMPairment:QUADrature[:ANGLe]
on page 409
[:SOURce]:BB:IMPairment:IQOutput<ch>:QUADrature[:ANGLe]
on page 411
Skew
Sets the time offset between the I and Q vectors.
In an I/Q modulator without I/Q skew, the I and Q vectors are aligned to the marker.
With an I/Q skew, both vectors are shifted relative to the marker so that the offset of
each of the vectors to the marker will be the half of the I/Q skew value.
A positive I/Q skew means that the Q vector delays relative to the I vector and vice
versa.
Remote command:
[:SOURce<hw>]:BB:IMPairment:SKEW
on page 409
[:SOURce]:BB:IMPairment:IQOutput<ch>:SKEW
on page 412
IQ Delay
Sets the time delay of both I and Q vectors relative to the selected trigger and marker
or relative to the other instrument(s) working in the master-slave synchronous mode.
A positive value means that the I and Q vectors delay relative to the marker/trigger or
to the other instrument and vice versa.

Optimize internal IQ-Impairments for RF Output
Activates/ deactivates internal compensation of signal distortions of the RF output. Sig-
nal distortions can be optimized for the RF output (active).
