SpectrumAnalysisWindowFunction
This attribute controls or indicates the windowing function
which will be used when performing the discrete Fourier
transform for the analysis. The WindowFunction and the
Equivalent Noise Bandwidth are related. If a particular
WindowFunction is selected, then the EquivalentNoiseBandwidth
for the function which is in use, will be reported by the
EquivalentNoiseBandwidth attribute. Alternatively if
an EquivalentNoiseBandwidth value is chosen then if a
WindowFunction function representing that
EquivalentNoiseBandwidth is defined in the CM, that value will
be reported in the WindowFunction MIB object, or a value of
'other' will be reported. Use of 'modern' windowing
functions not yet defined will likely be reported as 'other'.
Note that all window functions may not be supported by all
devices. If an attempt is made to set the object to an
unsupported window function, or if writing of the
WindowFunction is not supported, an error will be returned.
