Ettus USRP B310 Overview
The Ettus USRP B310 is an entry-level software-defined radio designed for research, prototyping, and deployment for next-generation wireless technologies.
The Ettus USRP B310 has two transmit and two receive channels, each with up to 100 MHz bandwidth, and two LOs for independent frequency tuning from 350 MHz to 7.2 GHz. Multi-device synchronization supports up to four Ettus USRP B310 devices without external hardware. The Ettus USRP B310 is available with Thunderbolt™ 3 bus for lab use and as a PCI Express plug-in card for easy system integration or native GPU coprocessing.
