About FFT Spectrum Analyzers
The FFT spectrum analyzer samples the input signal computes the magnitude of its sine and cosine components and displays the spectrum of these measured |
How to do FFT analysis?
Select Nyquist frequency to compute the THD to the maximum frequency equal to the Nyquist frequency.
The Nyquist frequency is half the sampling frequency of the selected signal.
Select Same as Max frequency to compute the THD to the maximum frequency equal to the frequency specified in the Max frequency (Hz) parameter.
