  1. Use {{{uhd_find_devices}}} to make sure that the onboard x310 SDR is detected as in the following image:

  Notice that running this command with no arguments will sometimes detect other SDR resources in the testbed which are reachable over the network. We can ignore those for now and focus just on the onboard x310. 
 
- 2.  Use the {{{uhd_usrp_probe}}} command to get more details on the x310 as in the following image. Specifying {{{--args="type=b200"}}} ensures only the directly connected radio is probed, instead of the radios on the network.
