Recently I'm using AD9364 to receive AM signal with FAST AGC settings. I got a problem.
I choose signal generator to generate the AM signal(carrier frequency is 245.01MHz, AM depth is 85%,AM RATE is 1KHz,RF power is -70dBm). Set Rx LO to 245MHz.
At first, I only set carrier signal on without modulation, FAST AGC works well while changing the input power ,and waveform is just fine as followed.
Then I set AM modulation on , someting wrong occurs,and waveform turn to be as followed:
I wonder what caused this issue.
Thank you !
