Hi @SASuba360,
Yes, the Analog Discovery 2 uses ADCs for its analog inputs, although as noted in the Analog Discovery 2 specifications, https://digilent.com/reference/test-and-measurement/analog-discovery-2/specifications, the resolution is only 14 bits.
In WaveForms, there is a FFT view option within the Scope tool,
as well as a more expansive option available in the Spectrum tool:
There is also a AnalogIn_FFT.py example that comes with WaveForms SDK:
Let me know if you have any questions.
Thanks,
JColvin
