It seems the maximum AD9361 RX gain is not about 70 dB as specified in the data sheet. My configuration is as floowing:

1. FDD at 460MHz and BW=4.35MHZ;

2. Use IIO Slow AGC default setting

3. The RSSI value on FPGA is -10 dB FSR when RX input signal is -30dBm. This seems the slow agc is functioning.

4. The RSSI value on FPGA is -14 dB FSR when RX input signal is -70 dBm. If input 4dBm  is corresponding to -2 dB FSR, this seems the maximum RX gain is about 62 dB. Ths gain is about 8dB short.

 

Thanks.
