I'm using AD9364 in Fast Attack AGC with Split table mode. We are also using an external LNA of 22dB gain and 2 variable gain amplifiers each of 19dB gain and variable attenuation of 0.5 to 31.5dB in steps of 0.5dB. Without using these amplifiers, My AGC settings works fine. If I want to use these front end module, how to configure my External LNA setting in AD9364 init?
Just entering the settling time for all these front end module itself is enough or do I also need to modify the split gain table?
