[Discuss-gnuradio] Gain and Sample Rate Setting

[Ben Gustin]

Hello all,
I have XCVR2450 USRP's. I have been trying to send the data between two
USRP's. I have made some changes to the python code in uhd_interface.py
where I have changed the gain to 25 and set the frequency for
transmitter and receiver to 2.435G. I have run uhd_fft program only to
find that my sample rate of 50k is not being supported. I am unable to
know how to set the sample rate and sps for my device. Because of that,
I have been receiving some errors like

ok = False  pktno =   88  n_rcvd =    1  n_right =    0
ok = False  pktno =  105  n_rcvd =    2  n_right =    0
ok = False  pktno = 49227  n_rcvd =    3  n_right =    0
ok = False  pktno =  117  n_rcvd =    4  n_right =    0
ok = False  pktno =  121  n_rcvd =    5  n_right =    0
ok = False  pktno =  122  n_rcvd =    6  n_right =    0
ok = False  pktno =  126  n_rcvd =    7  n_right =    0

I also have attached a graph of uhd_fft program. I think I have got a
wave which represents a transmission gain of 25 and received gain of 15
because I have specified it in the uhd_interface.py program.  Please
advice as to where I can change these settings so that I might be able
to receive packet in a right order. Thank you

Regards,
Ben
