Yes, I was sending all 1000 for each sample. I completely forgot that the DC component may be wiped. However, I also tried sending gaussian noise (mu=0, sig=1)*100 and still didnt see the signal.
Im going to take a closer look at the interface to determine which daughterboard and output is used (A or B) and also try to rx the signal with another USRP.
