Returns the spectral flatness margin, which is the minimum of the upper and lower spectral flatness margins. This value is expressed in dB.

The upper spectral flatness margin is the minimum difference between the upper mask and the spectral flatness across subcarriers. The lower spectral flatness margin is the minimum difference between the spectral flatness and the lower mask across subcarriers. When you set the OFDMModAcc Averaging Enabled property to True, the spectral flatness is computed using the mean of the channel frequency response magnitude computed for each averaging count.

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