To configure multiple devices connected to either separate USB 2.0 or 3.0 interfaces
or to a USB hub, assign a different device ID to each USRP device. Because each
USRP-2900/2901 device has the same default device ID, you must change the device
ID for each USRP device before you connect an additional device to the host
computer.
NI-USRP Instrument Driver
NI-USRP features a set of VIs and properties that exercise the functionality of the
USRP-2900/2901, including configuration, control, and other device-specific
functions. Refer to the NI-USRP Help for information about using the instrument
driver in your applications.
NI-USRP Examples
The instrument driver examples are instructional tools that demonstrate some of
the functionality of the USRP-2900/2901. You can use these examples separately or
integrate them into your systems. NI-USRP includes examples for getting started
and other SDR functionality. You can access the NI-USRP examples from the
following locations:
