We use AD9361 (AD-FMCOMMS3-EBZ) + Xilinx interface board (EK-Z7-ZC706-G) to do testing, then encountered 2 questions need your help as below.
1. We measured receiver power is "-12dBFS@2400MHz" through "iio oscilloscope".
From UG-570, we know 0dBFS=0.625V,
==> 10log[(V^2/R)/1mW] = 10*log(0.157^2/50*1000) = -3.07dBm.
Is it correct?
2. We found the units of RSSI is "dB", not "dBm". What the mean of RSSI=0dB ? How can we convert it to dBm?
