Programming the Device
You can use the NI-USRP instrument driver to create communications applications
for the USRP RIO device.
USRP RIO devices are LabVIEW FPGA targets, which support creating custom FPGAs
and configuring the device using Instrument Design Libraries (IDLs).
Note
You must use the PCIe x4 connector if you want to program the
FPGA. You cannot use the 1G/10G ETH connector to program the FPGA.
