Set Reference Symbols (Remote Command only)
Directly specifies I/Q data for Reference Symbols used in EVM measurement. (An
alternative method is to load the data from a file; see Recall Reference
Symbols@1600057.)

3.6.8.6 IQ Comp
Provides the capability to control separate compensation function explicitly.
Subcarrier I/Q Estimation
This parameter is available when Radio Std is 802.11n/ah/ac/ax/be.
Allows you to turn On or Off the estimation for IQ Gain Imbalance vs. subcarrier, IQ
Quadrature Error vs. subcarrier in the input signal.
