Hi Marcus, first I want to thank you for your very fast reply. I am sorry for not reporting details about my system setup.
I am using a USRP1 model and I have one XCVR2450 daughterboard attached. Two antennas are connected at the pigtails on the daughterboard. I used the build-gnuradio install script to for installation and so I downloaded the latest versions from the 'main' branch for both UHD and GNU Radio. I just set the gain at the maximum level and I notice that signals can be received at the level of -35dBm. Can I use the usrp_oscope.py to capture plots of the transmitted frames. My main aim is to able to plot the exact duration of a transmitted frame, ack packets etc. I hope the information I provided can help you. Thank you, Stratos.
