Windowed FFT PtByPt (Not in Base Package)

Computes the windowed fast Fourier transform of the input data.

initialize, when TRUE, initializes the internal state of the VI.
input data is a set of real data.
sample length is the length of each set of incoming data. The VI performs computation on each set of data. The default is 100. sample length must be greater than zero.
window selector determines the type of analysis window the VI uses to compute the windowed FFT.

Windowed FFT is the Windowed Fast Fourier Transform of the input data.
error returns any error or warning condition from the VI. Refer to Point By Point Error Codes for more information about these conditions.
