Ettus Research, a National Instruments company, has introduced the USRP X300 and USRP X310 high-performance, modular software defined radio (SDR) platforms. Both platforms combine two RF transceivers covering DC–6 GHz with up to 120MHz bandwidth and a large user-programmable Kintex-7 FPGA.

Both platforms feature multiple high-speed interface options, including PCI Express, dual 10Gigabit Ethernet and dual 1Gigabit Ethernet and is available in in a convenient desktop or rack-mountable half-wide 1U form factor.

The USRP Hardware Driver (UHD) architecture, common to all NI USRP (Universal Software Radio Peripheral) devices, provides a comprehensive, easy-to-use interface. Developers can programmatically control the USRP with the UHD C++ API, or choose from a wide selection of third-party tools and software such as GNU Radio.

The two new platforms use a flexible software ecosystem to deliver cost-effective, high-performance SDR solutions that help wireless system designers quickly create simple prototypes, develop complex systems and accelerate their wireless research.Both leverage the Kintex-7 family of FPGAs from Xilinx. The USRP X300 uses the XC7K325T, and the USRP X310 is based on the larger XC7K410T. Kintex-7 FPGAs integrate up to 1,540 DSP48 slices operating in parallel so USRP users can deploy custom or third-party signal processing algorithms onto each device. Users can process data in real time using their own DSP algorithms such as filters, modulators/demodulators and coders/decoders. They can also access and control the wide range of peripherals available on each USRP, including the RF front ends.
