v5 v6 97 97 === Run the experiment === 98 98 * Run rfnoc_spec_sense_display on the receive node. The command below starts the application to receive spectrum sensing samples from 4 USRP X310s at 100MSPS. 99 {{{ 100 root@node1-19:~/uhd/host/build/examples# ./rfnoc_spec_sense_display --args="addr0=10.10.23.11,addr1=10.10.23.12,addr2=10.10.23.13,addr3=10.10.23.14,skip_ddc,skip_duc" --freq 5e9 --gain 15 --ddc-args="input_rate=200000000.0,output_rate=100000000.0" --num-usrp 4 --spec-sense-args="avg_size=256" 101 }}} 99 102 * Run rfnoc_spreader on the transmit node. The command below starts the application to send a 50MHz wide PN signal on node23-17. 103 {{{ 104 root@node1-20:~/uhd/host/build/examples# ./rfnoc_spreader --args="addr=10.10.23.17,skip_ddc,skip_duc" --freq 5e9 --gain 15 --duc-args="input_rate=50000000.0,output_rate=200000000.0" 105 }}} 100 106 * Download spec_sense_display.html and open it in your browser. Once you click the Start button, you should see power spectrum display as shown below. 101 107
