"Fast"
Fast optimization by compensation for I/Q skew.
This mode suitable in time sensitive environments.
"High Quality Table"
Enabled if R&S SZU is connected to the R&S SMW and the connec-
tion is active.
This mode provides improved optimization while maintaining setting
time.
"High Quality"
With "Source > Internal Baseband", enables an optimization by com-
pensation for I/Q skew and frequency response correction.
This mode generates flat signal but requires longer setting time and
leads to signal interruption.
Note:
Do not use the mode "I/Q Modulator > Optimization Mode > High
Quality" in combination with the modes "RF Level > Setting Charac-
teristics > Uninterrupted Level Settings/Strictly Monotone".
The high quality I/Q optimization leads to RF signal interruption. The
requirements of the RF level modes "Uninterrupted Level Settings"
and "Strictly Monotone" can not be fulfilled.

Optimization Bandwidth
For "Optimization Mode > High Quality/High Quality Table", defines how the signal
bandwidth on that frequency response is compensated is selected.
"Auto"
Signal bandwidth is determined automatically, it corresponds to the
bandwidth of the baseband signal.
"Manual"
Signal bandwidth is set with the parameter Bandwidth.

In "Optimization Bandwidth > Manual", sets the signal bandwidth on that frequency
response is compensated.
