MATLAB Code for Wavevision FFT

Rakend R
Prodigy 140 points
Other Parts Discussed in Thread: ADS61B29

Hi,

I'm looking for a MATLAB code which will do the FFT calculation similar to wavevision. I want this for plotting the captured data of 12 bit ADC ADS61B29 .

FFT Window : Blackman Harris

Bins to omit at DC and fund is reset value.

PS: I've written one MATLAB code, but it will not take care of windowing and bins to omit at DC and fund. Thus I'm seeing some deviation from Wavevision and MATALB (Fund amplitude is differed by 2dB). I've attached one input file with 2s complement enabled, sampled at 3.125MHz and 12 bit resolution.
