[ASHLY19]

Hello every one:

I am trying to generate chirp signal and receiving it using USRP(2932) , the transmit port (TX1) of the USRP is connected to the receiving port (RX2) of the same USRP through RF cable .

How I ensure that the signal is received correctly , what is the shape of the received signal and its properties ?

 the transmitted signal is attached in the figure below
