 As there are two radios, this experiment can be run on either one by changing the value of the {{{usrp_sink_addr}}} and {{{usrp_source_addr}}}. The available values are {{{192.168.30.3}}} and {{{192.168.30.4}}}, and {{{usrp_sink_addr}}} and {{{usrp_source_addr}}} must be set to the same value.

 '''Details on configuring the canceller PCB'''
+
 Using the experiment {{{node_level_sic_fd_gui}}}, the experimenter can configure the RF canceller PCB using the experiment GUI. There are 12 sliders:
  * {{{cap0, cap1, cap2}}} - these control the antenna tuner.

 The experiment GUI will show a visualization of the received power spectrum and self-interference (SI) channel. Using this, the experimenter can generate any desired RF SIC profile.
 
-The GUI also provides a slider for the Tx/Rx delay. This setting is important for digital SIC performance, and the optimal value depends on the bandwidth used. For 10 MHz bandwidth, a delay of 40 should lead to the best digital SIC performance.
