How to make a distortion analysis(THD+N,SINAD,etc)

Hello,

I'm using the pico 2405A and C++ to make a distortion analysis with FFT, Thd+N, SINAD,etc.
I use the API to read the waveform data( ADC or mv ). But I do not know how to analyze(FFT, Thd+N, SINAD,etc) these data ?

Thanks,
John

You will need to look for third party software to help with this, Intel Integrated Performance Primitives (Intel IPP) would be one suggestion..
