4. (Optional) Connect the AC/DC power supply to the PWR connector on the back
panel of the USRP device, and plug the power supply into a wall outlet.
Note
NI recommends that you connect the device to an external
power supply if you plan to use both channels of the USRP device.
However, if you plan to use only one channel, bus power may be
acceptable.
You can connect and synchronize multiple USRP-2900/2901 devices using an
external Reference Clock distribution system such as the CDA-2990 Clock
Distribution Device. However, USB performance varies when multiple devices
stream through the same controller. Consider using a USRP RIO device if you need
to build a high-channel count system.
