     98To set the DSA energy detection threshold use the --threshold command line argument with a given threshold: 
     99 
     100{{{ 
     101 sudo python ./benchmark_dsa.py --threshold 1.5e8 
     102}}} 
     103 
     104At this point a single node will begin scanning over the specified channels looking for other nodes.  In order to complete the demo, perform the same setup procedure on another node and the two nodes will rendezvous and begin exchanging data.   
     105 
     106The console screen shows the rendezvous channel.  To test the DSA capabilities simply simulate a primary user by transmitting energy on that specific channel.  In our case, by default the nodes use the FRS band, channels 1,7,8, and 14.  An FRS 2-way radio can be used to cause the DSA process to start.  Once the nodes sense energy above the specified energy threshold, they will begin to scan over multiple channels in order to rendezvous once again.
