Acquire Data

Acquire Data

At this point you are ready to capture data from the ADC. You can do so by clicking on the red circular
Acquire Data button located below the graph. The button turns green and stay green until the capture is
complete. After it is complete, you will see a FFT plot as well as Capture Statistics and FFT Computations.

Capture the ADC Samples, Perform an FFT, and Plot the Results
