Installing the Device

Install all the software you plan to use before you install the hardware.

Note The USRP device connects to a host computer using a standard gigabit Ethernet interface. Refer to the documentation for your gigabit Ethernet interface for installation and configuration instructions.
  1. Power on the computer.
  2. Attach the antenna or cable to the front panel terminals of the USRP device as desired.
  3. Use the Ethernet cable to connect the USRP device to the computer. For maximum throughput over Ethernet, NI recommends that you connect each USRP device to its own dedicated gigabit Ethernet interface on the host computer.
  4. Connect the AC/DC power supply to the USRP device .
  5. Plug the power supply into a wall outlet. Windows automatically recognizes the USRP device .

Synchronizing Multiple Devices (Optional)

You can connect two USRP devices so that they share clocks and the Ethernet connection to the host.

  1. Connect the MIMO cable to the MIMO EXPANSION port of each device.

  2. If you have not already done so, attach antennas to the USRP devices.
    If you want to use one USRP device as a receiver and the other as a transmitter, attach one antenna to the RX 1 TX 1 port of the transmitter, and attach another antenna to the RX 2 port of the receiver.
The NI-USRP driver ships with some examples that you can use to explore the MIMO connection, including USRP EX Rx Multiple Synchronized Inputs (MIMO Expansion) and USRP EX Tx Multiple Synchronized Outputs (MIMO Expansion).
