Digilent NI Ettus USRP X310 2x2 SDR/Cognitive Radio

Digilent NI Ettus USRP X310 2x2 70MHz-6GHz SDR/Cognitive Radio is a high-performance, scalable software-defined radio (SDR) platform for deploying and designing next-generation wireless communications systems. The hardware architecture combines two extended-bandwidth daughterboard slots covering the DC to 6GHz range with multiple high-speed interface options (PCIe, Dual 1/10 GigE), up to 160MHz of baseband bandwidth, and a large user-programmable Kintex-7 FPGA in a convenient rack-mountable or desktop half-wide 1U form factor. In addition to providing best-in-class hardware performance, the open-source software architecture of the Digilent NI Ettus USRP X310 provides cross-platform UHD driver support, making it compatible with a large number of USRP-supported development frameworks, reference architectures, and open-source projects.
