When you enter the FFT editor, you must select the window function. This
instrument has the following six FFT windows.
Rectangle
Hanning
Hamming
Blackman-Harris
Blackman
Triangle
For repetitive waveforms in which the waveform data starting point and
ending point match, the rectangle window is usually used. For details on the
window functions, see the FFT (Fast Fourier Transforms) description in
Appendix F.
6. Next, select O.K. from the side menu to enter the FFT editor. The time
domain data is transformed into the frequency domain.
To cancel the FFT operation, select Cancel. This returns the system to the
initial EDIT menu.
