How can I create a test file of IQ data similar to the output from AD9695 dual ADC? I do not see an option in Virtual Eval Beta Tool, to output the IQ data, only a plot of the FFT.
We are using the AD9695 at 400 and 600M sample clock rate. Input RF signal is 240-270M; the decimation rate is 8 or 12, (400/8 = 600/12 =50Msps); DDC ON, NCO typically =240-270M.
We see a 250M spur in the FFT output data, not present in the Virtual Eval Beta simulation. I want to replace our measured real data with a simulated output from sampling/decimation/DDC processing to confirm the 250M spur is not an artifice.
