Call for price

Provides deterministic control of transceivers using an onboard FPGA and processor for rapidly prototyping high-performance wireless communications systems.

The USRP Software Defined Radio Stand-Alone Device built with an FPGA and an Intel i7 onboard processor which you can provision with NI Linux Real-Time, Linux Fedora, or Linux Ubuntu Real-Time Operating Systems. You can program the onboard processor and FPGA with LabVIEW Communications System Design Suite or use an open-source software workflow to deterministically control your application.

The USRP-2974 is ideal for prototyping a range of advanced research applications that include stand-alone LTE or 802.11 device emulation; Medium Access Control (MAC) algorithm development; multiple input, multiple output (MIMO) systems; heterogeneous networks; LTE relaying; RF compressive sampling; spectrum sensing; cognitive radio; beamforming; and direction finding.
