Should I get samples with a magnitude > 128 from the USRP no FPGA gain?
I believe the answer is no. Take a look at these plots of the data I
am getting (plot of real portion only):
I collected the data using this method:
./usrp_rx_cfile.py -d 16 -f 1575420000 -g 0 -N 4000000 file.dat
Furthermore, I created a test jig which wrote USRP output to stdout and
verified these spikes are not in the binary file or the binary file
reader. I’m using the DBSRX with a GPS antenna and a low noise
