Description
The TWNDOW command creates a window trace array for the fast
Fourier transform (FFT) function. The trace-window function creates a
trace array according to three built-in algorithms: UNIFORM,
HANNING, and FLATTOP. When used with the FFT command, the
three algorithms give resultant passband shapes that represent a
compromise among amplitude uncertainty, sensitivity, and frequency
resolution. Refer to the FFT command description for more
information.
The three types of windows that are available when using the
TWNDOW command are:
FLATTOP
HANNING
UNIFORM

provides optimum amplitude accuracy.
provides an amplitude accuracy and frequency
resolution compromise, which is useful for general
purpose measurements, as well as noise
measurements.
provides equal weighing of the time record for
measuring transients.
