Hello all,
I have to receive the Satellite data through the antenna and it is a
secondary thing. Before going to check the satellite data i have to check
the signal generator because they both are doing same processing. So, i
recently test the signal generator power using the USRP. Here i am getting
one issue is that when i giving -40dB gain value to the USRP from the
signal generator the wave is showing the received data is -36dB. One more
signal is -63dB and i am receiving the -39dB. There is a small difference
between receiving data when compared to input data.
I have to know what is the USRP gain and how it is processing the
signal generator or satellite data? I am giving the some power from signal
generator and what happens if i change the gain in "USRP Source"? I noted
the data from -110dB to +110dB and the receiving data is not changing from
-110dB to 0dB, it is changing from 0dB to 50dB. The same process is
continued for -63dB also.
Can anyone kindly help me to solve this issue! If anyone has
advices and comments, they would be greatly appreciated.
Best Regards,
M.Jahnavendra
