    5959 1. ssh to node3-1 and start the rx_ascii_art_dft demo with the following command:
    6060 {{{
    61  /usr/lib/uhd/examples/rx_ascii_art_dft --args "resource=rio0,type=x300" --freq 2400e6 --rate 5e6 --frame-rate 10 --gain 10 --ref-lvl -30 --dyn-rng 70
     61 /usr/lib/uhd/examples/rx_ascii_art_dft --args "resource=rio0,type=x300" --freq 2455e6 --rate 5e6 --frame-rate 10 --gain 10 --ref-lvl -30 --dyn-rng 70
    6262 }}}
    6363 Note that we are looking at the frequency band around 2.4GHz. You should see an output similar to this:
    … …  
    6767 2. ssh to node3-20 and start the tx_waveforms demo with the following command:
    6868 {{{
    69  /usr/lib/uhd/examples/tx_waveforms --args="resource=rio0,type=x300" --wave-freq 1e6 --wave-type SINE --freq 2400e6 --rate 5e6 --gain 10 --ampl 0.2
     69 /usr/lib/uhd/examples/tx_waveforms --args="resource=rio0,type=x300" --wave-freq 1e6 --wave-type SINE --freq 2455e6 --rate 5e6 --gain 10 --ampl 0.2
    7070 }}}
    7171
    … …  
    7676 We can generate a different type of signal by changing the {{{wave-type}}} argument. For instance, if we transmit a square wave:
    7777 {{{
    78  /usr/lib/uhd/examples/tx_waveforms --args="resource=rio0,type=x300" --wave-freq 1e6 --wave-type SQUARE --freq 2400e6 --rate 5e6 --gain 10 --ampl 0.2
     78 /usr/lib/uhd/examples/tx_waveforms --args="resource=rio0,type=x300" --wave-freq 1e6 --wave-type SQUARE --freq 2455e6 --rate 5e6 --gain 10 --ampl 0.2
    7979 }}}
