Specifies whether to enable pilot-based mean amplitude tracking per OFDM data symbol.

Amplitude tracking is useful if the mean amplitude of the OFDM symbols in a PPDU varies over time. However, enabling tracking may degrade EVM because of attempts to track random amplitude distortions caused by additive noise and other distortions.

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.
