 We need to adapt the scenario file to include the spectrum analyzer. We are using nodes 4 and 6 to do the OFDM transmission, and if we look at the {{exp_room_with_nodes_positions.png?linkonly|Nodes Placement Map}}, we see that for example node 23 is a good candidate to execute the spectrum analyzer script.
-Edit ''scenario.desc'' to add the node 23 with 'sa.py' as the entry point. Also increase the number of packets sent by node 6 (option -M). Your file should look like this :

 ### Observe the result
-Go back to the web page where we created the graph. Around twenty seconds after launching the experiment the graph should start to animate with the result and you can observe a graph representing an OFDM transmission which should look like this :{{ :ofdm-sa.png?direct&200 |}}
