I wanted to know whether the PI Interface can detect the oscillation exactly at the time that it occurs( in real-time). As shown in the screenshot, I have a oscillating signal. The current time is 7:15:21 PM but the FFT magnitudes of the oscillating signal that are being displayed is of the time 7:08:27 PM. Is it possible for the FFT interface to display the FFT outputs at 7:15 PM ( with a few seconds delay) or will there always be a large delay (in minutes) in displaying the FFT outputs?
