I'm working on an AD9361 (FMCOMMS3 board) with Linux project, and I had a few question about the rssi when receiving signals.
- Is the RSSI linear? i.e. If I increase the transmit power by 20 db, will I see a 20 db increase at RSSI? What about 40? From my tests it appears so but I wanted to double check.
- Is it possible to calibrate the RSSI through the Linux shell or libiio?
- What does the calibration generate? A table? Offset? Something else?
- Does calibration automatically save it to non-volatile memory?
