to set the scale and position of the horizontal axis respectively.
The unit of the vertical axis can be dB or Vrms which use logarithmic mode and
linear mode to display vertical amplitude respectively. If you need to display the
FFT frequency spectrum in a relatively larger dynamic range, dB is
recommended. Press Scale to select the desired unit and the default is Vrms.

Tips
Signals with DC components or deviation would cause error or deviation of the FFT
to “AC”.
To reduce the random noise and aliasing frequency components of repetitive or
