FFT Application Hints
Some practical suggestions:
(I)
To increase the frequency resolution, increase the length of the
time domain waveform record (i.e. use a slower time base).
(2) To increase the frequency range, increase the effective sampling
frequency (i.e. increase the Transform Size).

Fast Fourier Waveform Processing
Option (WP02, V 2.06FT)
