Product Description

 

 

 

 

 

Overview

 

The USRP N321 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 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 N321 provides a path to building large, phase coherent MIMO testbeds for a variety of advanced wireless research topics. In addition, the USRP N321 allows for the export of TX and RX LOs in a Star configuration to multiple other USRP N320 or USRP N321 devices.

 

The USRP N321 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 N321 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 N321 is available in two variants:

 

• Standard variant with TPM (PN 786504-01)




• Non-TPM variant (PN 786919-01)



 

 

Only the non-TPM variant of the USRP N321 will be available in the People's Republic of China and Hong Kong. USRP N321 with TPM will not be available in France, Israel or Russia until the N321 is registered in those countries. Please contact sales@ if you would like more information.
