Selecting a spectral window

A spectral window determines what the filter shape of the spectral analyzer will be in the frequency domain. It may be described
by a mathematical function that is multiplied point-by-point times the input data to the spectral analyzer.

The following spectral windows are available with the instrument:

■

Rectangular

■

Hamming

■

Hanning

■

Kaiser-Bessel

■

Blackman Harris

■

Gaussian

■

Tek Exponential

■

Flattop2

The windows are listed in the order of their ability to resolve frequencies (resolution bandwidth). You can easily observe the
shape of a window in the frequency domain by feeding a sine wave into the instrument and setting the center frequency of the
spectral analyzer to the same frequency. Then reduce the resolution bandwidth to spread out the lobe horizontally. You can then
select different window functions and observe their shape.
