6.9. Fourier transformation function (FT)
The Fourier transformation transforms acquired samples using the Fourier
transformation. The FFT (fast Fourier transformation) and DFT (discrete Fourier
transformation) are implemented. In case the automatic period selection is activated,
one period of the waveform is transformed; otherwise the part distinguished by the
cursors in the oscilloscope software is transformed.
The Fourier transformation window is opened after activation of the FT function.

The main screen is located in the top of the window. The frequency bar divides it into
two parts. You can change the parts‘ size by dragging this bar. The harmonics‘
amplitude is displayed in the top part (amplitude part), the phase in bottom part.
