RECTangular
The rectangular window has high frequency accuracy with thin
spectral lines, but with increased noise. Use this function pref-
erably with pulse response tests where start and end values are
zero.
HAMMing
The Hamming window has higher noise level inside the spec-
trum than Hann or Blackman, but smaller than the rectangular
window. The width of the spectral lines is thinner than the other
bell-shaped functions. Use this window to measure amplitudes
of a periodical signal precisely.
HANNing
The noise level within the spectrum is reduced and the width of
the spectral lines enlarges. Use this window to measure ampli-
tudes of a periodical signal precisely.
BLACkmanharris
In the Blackman window, the amplitudes can be measured pre-
cisely. However, determining the frequency is more difficult. Use
this window to measure amplitudes of a periodical signal pre-
cisely.
FLATtop
The flat top window has low amplitude measurement errors but
a poor frequency resolution. Use this window for accurate sin-
gle-tone measurements and for measurement of amplitudes of
sinusoidal frequency components.
