Description Window
Kaiser
The frequency resolution when using the Kaiser window is fair; the spectral leakage and
amplitude acc
uracy are both good.
The Kaiser window is best used when frequencies are very close to the same value but have
widely differing amplitudes (the side lobe level and shape factor are c losest to the traditional
Gaussian RBW
). This window is also good for r andom signals.
Rectangular
The frequenc
y resolution when using the Rectangular (a.k.a. boxcar or none) window is very
good, the spectral leakage is high, and amplitude accuracy is poor.
Use the Rectangular window for measuring transients or bursts where the signal levels
before and a
fter the event are nearly equal. Also, use this window for equal-amplitude sine
waves with frequencies that are very close together, and for broadband random noise with a
relatively slow varying spectrum. This window is the best type for measuring the frequency
spectrum o
f non-repetitive s ignals, and measuring frequency components near DC.
Hamming
The freque
ncy resolution when using the Hamming window is good (slightly better than
Hanning), the spectral leakage is moderate, and amplitude accuracy is fair.
Use the Hamming window for measuring sine, periodic, and narrow band random noise. This
window wo
rks well on transients or bursts where the signal levels before and after the event
are significantly different.
Hanning
The frequency resolution when using the Hanning (a.k.a. Hann) window is good, the spectral
leakage is low and amplitude accuracy is fair.
Use the H
anning window for measuring sine, periodic, and narrow band random noise. This
window works well on transients or bursts where the signal levels before and after the event
are significantly different.
Blackman-Harris
The frequency resolution when using the Blackman-Harris window is poor, the spectral
leakag
e is very low and amplitude accuracy is good.
Use the Blackman-Harris window for m easurin g predominantly single frequency waveforms to
look for higher order harmonics, or several moderately or widely spaced sinusoidal signals.
Flat-Top
The frequency resolution when using a Flat-Top window is poor, the spectral leakage is
low an
d amplitude accuracy is very good.
Use the Flat-Top window for making accurate amplitude measurements of moderately or
widely spaced sinusoidal signals.
