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
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!
