Operation On/Off
Click or tap the Operation on/off switch to enable 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, then the higher the sample rate, the higher the resolution.
NOTE
The number of FFT analysis points can be 1 Mpts in maximum.
