Figure 9.7 FFT Operation Menu
Operation
Click or tap the Operation on/off switch to enable or disable the FFT operation result
window. The parameters such as center frequency, frequency range, and resolution
are displayed at the top of the window, as shown in the figure below. FFT resolution is
the quotient of the sample rate and the number of FFT points. If the number of FFT
points is a fixed value (65535 at most), then the lower the sample rate, the higher the
resolution.
