Good for magnitude, but poorer frequency resolution
than Hamming.
Recommend to use for:
Hanning


Better solution for magnitude than Rectangle, and good
for frequency as well. It has slightly better frequency
resolution than Hanning.
Recommend to use for:
Hamming


Best solution for magnitude, worst for frequency.
Recommend to use for:
Blackman

The Bartlett window is a slightly narrower variant of the
Bartlett
triangular window, with zero weight at both ends.
The frequency resolution when using the Kaiser window
is fair; the spectral leakage and amplitude accuracy are
both good.
The Kaiser window is best used when frequencies are
Kaiser
very close to the same value but have widely differing
amplitudes (the side lobe level and shape factor are
closest to the traditional Gaussian RBW). This window is
also good for random signals.
Notes for using FFT
 Use Zoom function to magnify the FFT waveform if necessary, see "Die
