Perform Fast Fourier Transform Analysis
To analyze the performance of the XADC in the frequency domain, select the Frequency
Domain tab (see
on the XADC data just viewed in the time domain. The signal-to-noise ratio, total
harmonic distortion, effective number of bits (ENOB), and other AC parameters are
calculated and displayed in the data panel below the FFT plot as shown in
new data capture from the XADC can be collected by pressing the Collect Data button.

Pressing the Collect Data button collects 4,096 XADC data points
and performs an FFT on it.7
