Issue Details

How can I connect my NI USRP RIO to my host computer? What real-time data bandwidth can the different interfaces provide?


You can connect to your NI USRP with one of the following options:
  • PXI Express Interface via MXIe x4 with 200 MHz BW
  • Host PC via MXIe x4 with 200 MHz BW
  • Host Laptop via MXIe x4 to x1 with 50 MHz BW
  • Host PC via 1 Gigabit Ethernet with 25 MS/s
  • Host PC via 10 Gigabit Ethernet with 200 MS/s

Additional Information

The primary bus interface for the USRP RIO is PCIe x4 which provides an effective connection for high bandwidth and lower latency applications such as PHY/MAC research. The bus allows users to stream data at 800MB/s and customize the FPGA in LabVIEW FPGA. The interface is backwards compatible with programs written for the NI USRP-292x and NI USRP-293x devices. The NI USRP-294x/295x devices with the NI-USRP driver in LabVIEW also support connectivity over 1G and 10G ethernet using the SFP+ ports on the back of the device, however it is not possible to modify the FPGA when connected over ethernet.
