Dear all, I'm wondering how to correspond the amplitude set in software to the voltage of the signal. I did some test, which demonstrate that setting the amplitude to 32767 and the GPA gain to 20dB could reach full scale 2V p-p. I'm confused about the amplitude setting in software, if 32767(which is 2^15-1) reaches the full scale, which means the amplitude is 16-bit data, but the ADCs are only 14-bit. How could the amplitude setting correspond to the voltage of the signal? What about the receiver side?
A simple question: if using usrp_source_c to receive complex signal by LFRX, does both of RX_B and RX_A ports should connect to antenna? This is for double checking if my system setting is correctly. Really appreciate any of your help! Wish you a great weekend!
