Hello everybody  
I just start working on USRP with Gnu radio. In last two weeks I was  
looking for tutorial to test my USRP without programming any blocks. The  
only tutorial I found is an FM receiver, but unfortunately frequency  
range of USRPN210 is way much bigger than FM frequencies (400MHZ-to  
GHZ).

I am asking if there is any resources that can I use to make familier  
with dealing with USRPN210 and gnuradio, like spectrum analyzer “I  
searched a lot but couldn’t found”.

I just need anything to observe the input of the USRPN210 , like  
detecting WI-FI signal or anything….

Thank you in advance and sorry for poor English.
