Short Name: DDemod EVM Norm Ref

Property of RFmxDemod

Specifies the reference used to normalize the error vector magnitude (EVM).

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is Peak.

Peak (0)

The EVM is normalized to the peak magnitude of the reference symbols.

RMS (1)

The EVM is normalized to the RMS magnitude of the reference symbols. This value is applicable only to modulation types, such as quadrature-amplitude modulation (QAM). This value is expressed in which the symbols in the map do not have a constant amplitude.
