First thanks to Micheal and Eric for their help.
I am in the process of testing my USRP board and I just have a question
how should I understand that USRP works while I am testing it through
gnuradio-examples? because I run the
./usrp_fft.py and ./usrp_oscope.py a window pops up with this
and shows some noises.
Is that what I suppose to get when I run these commands or I need to get
some other information as well?
Appreciated for your help.
