The USRP N320 is a networked software defined radio that provides reliability and fault-tolerance for deployment in large-scale and distributed wireless systems. This device simplifies control and management of a network of radios by introducing the unique capability to remotely perform tasks such as updating software, rebooting, factory resetting, self-testing, host PC/ARM debugging and monitoring system health. The USRP N320 is an all-in-one device that includes the Zynq-7100 SoC baseband processor, two SFP+ ports, a QSFP+ port, a built-in GPSDO module, and various other peripheral and synchronization features.

The USRP N320 is a networked software defined radio that provides reliability and fault-tolerance for deployment in large scale and distributed wireless systems. This is a high performance SDR that uses a unique RF design by Ettus Research to provide 2 RX and 2 TX channels in a half-wide RU form factor. Each channel provides up to 200 MHz of instantaneous bandwidth, and covers an extended frequency range from 3 MHz to 6 GHz. The baseband processor uses the Xilinx Zynq-7100 SoC to deliver a large user programmable FPGA for real-time, low latency processing and a dual-core ARM CPU for stand-alone operation. Support for 1 GbE, 10 GbE, and Aurora interfaces over two SFP+ ports and 1 QSFP+ port enables high throughput IQ streaming to a host PC or FPGA coprocessor.

A flexible synchronization architecture with support for 10 MHz clock reference, PPS time reference, external TX and RX LO input, and GPSDO enables implementation of phase coherent MIMO testbeds. With the ability to import both TX and RX LOs for any supported frequency above 450 MHz, the USRP N320 provides a path to building large, phase coherent MIMO testbeds for a variety of advanced wireless research topics.

The USRP N320 leverages recent software developments in UHD to simplify control and management of multiple devices over the network with the unique capability to remotely administrate tasks such as debugging, updating software, rebooting, resetting to factory state, and monitoring system health.

Trusted Platform Module (TPM)

The USRP N320 includes a Trusted Platform Module to enable security features such as file encryption. Due to product compliance restrictions on products with TPM (Trusted Platform Module) components to a few countries, the USRP N320 is available in two variants:
