Showing the wireless spectrum using USRP
After following the JFed Tutorial you can execute commands to perform experiments in the USRP. The first basic command is to check if the equipment is detected. To do this, run the command uhd_find_devices.
On the ‘rx_node’, run the following code:
cd /usr/lib/uhd/examples
./rx_ascii_art_dft –freq 2550000000 –rate 2000000 –ref-lvl -50
You should be able to see the ASCII representation of the transmitted waveform spectrum, as illustrated below:
