I have application with AD9874 eval-board & HSC-ADC-EVALCZ.

I use this pattern

FFT and samples you can see on the pictures


Red - is a part of complex IQ signal(I use complex splitter on the picture above)

Blue - is a SSI DATA  of automatic gain correction.


My question is - is it possible in visual analog to demodulate red signal?

True signal, what I need have this shape(like SSI DATA)


Please help me, thank you in advance!


Best regards
