5.Using the general purpose knob, select the window function.
When you enter the FFT editor, you must select the window function. This instrument has the following six FFT windows.
Rectangle Hanning Hamming
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.
