The cutoff frequency of the anti-aliasing filter is the same as the selected
frequency range, except for the cases listed below.
*1: Anti-aliasing filter is OFF.
*2: Cutoff frequency is 20 Hz.
*3: FFT Number of Points values of 2000, 5000 and 10,000 correspond to
multiples of 1/2, 1/5 and 1/10, respectively.
*4: FFT Number of Points values of 2000, 5000 and 10,000 correspond to
multiples of 2, 5 and 10, respectively.
This setting determines the sample count (Number of Points) used for FFT
calculation. A higher setting increases the frequency analysis capability, but
also increases the processing time required.
