Configuration for External LNA

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?

I'm using Split table mode.

  • Is it good to add these gain value in Gain table or adjust the peak detect time for AGC to compensate for the settling time of Front end Analog amplifiers?

    If it is good to add gain values in gain table, how will I add these values in "Split table" mode?

    Adding LNA gain in gain table won't impact AGC operation, it will just affect the RSSI measurement. Am I right?
