Hey , the best starting point is the tutorials at the link: http://www.nd.edu/~jnl/sdr/docs/tutorials/
for test the daughter board , use the examples in the usrp directory use the usrp_scope and usrp_siggen you can send a signal and receive it this way . About adjusting the PGA use "src.set_pga" thats all i can help with hope thats enough ziad zhifeng wrote: > > Hi, > I am a beginner in USRP for GNU Radio.
