single channel. If possible perform the test in a conducted fashion, connecting 70 dB of attenuation to the radio that is not the
DUT. Connect a splitter or RF-T to the DUT radio, attaching a spectrum analyzer or power meter to one port and the non-
DUT radio via 70 dB of attenuation to the other port.
Power up both the manager and the mote. Connect to the CLI port of the manager. Enter the following command
> onechan <channel>
Where channel number is any channel between 0 and 14. Reset or power cycle both the mote and manager. The devices will
hop on a single channel after rebooting and forming a network.
