I'm trying to test the AD9361 RX with some tones/sine waves within the band at the RX analog input. configuring AD9361 in FDD and slow attack mode with AGC mode. with LTE5 MHz I see the gain table index, the measured RSSI value and the channel power looks relevant to the input power level but with LTE10 MHz I can't measure the same RSSI properly. Although the input signal level stays constant each time I read the RSSI value (reg 0x1A7) it changes. I tried to modify few parameters with gain control but no luck.
Which parameters I should be looking into for this?
Thank you for your help.
