The adjustment is only possible when "RF > On" and "I/Q Mod > State > On".
Adjustment for only the set frequency is considerably faster than adjustment across the
entire frequency range. An adjustment of the entire range is possible with the I/Q Mod-
ulator button of this dialog.
Remote command:
:CALibration:IQModulator:LOCal? on page 228
Synthesis
Performs all adjustments which affect the frequency.
Remote command:
:CALibration:FREQuency[:MEASure]? on page 227
Level
Performs all adjustments which affect the level. The acquired correction values
improve the settling time and the signal quality.
Remote command:
:CALibration:LEVel[:MEASure]? on page 228
I/Q Modulator
Starts the adjustment procedure for the I/Q modulator and/or the baseband for the
entire frequency range. The I/Q modulator is adjusted regarding carrier leakage, I/Q
imbalance and quadrature.
To accelerate the adjustment procedure, you can enable performing adjustments for
the I/Q modulator and the baseband separately.
Remote command:
:CALibration:IQModulator:FULL? on page 228
Delta Temperature
Displays the difference between the current temperature and the temperature by the
last performed adjustment.
Note: Adjustment is recommended if the temperature range in which the instrument is
operated changes, before all applications which require maximum level and frequency
accuracy, or after enabling/disabling of the "Eco Mode" (see Chapter 10.10, "Eco
mode", on page 156).
