The USRP E320 brings performance to embedded software defined radios by offering four times more FPGA resources compared to the USRP E31x devices. The USRP E320 also introduces improvements in streaming, synchronization, integration, fault-recovery, and remote management capability. This field deployable SDR continues to use the flexible 2×2 MIMO AD9361 transceiver from Analog Devices, which covers frequencies from 70 MHz – 6 GHz and provides up to 56 MHz of instantaneous bandwidth.

The USRP E320 is available in both 3U board-only and fully enclosed form factor variants. The compact size of the USRP E320 is highly suitable for deployment as a mobile radio in manpacks or mounted on unmanned ariel vehicles.

The open-source USRP Hardware Driver (UHD) API and RF Network-on-Chip (RFNoC) FPGA development framework reduce software development effort and integrate with a variety of industry-standard tools such as GNU Radio. Users can rapidly prototype and reliably deploy designs for a variety of SDR applications such as spectrum monitoring and analysis, base station and UE emulation, mobile radio, and UAV communication/detection.

Baseband Processor

The baseband processor uses the Xilinx Zynq-7045 SoC to deliver a large user-programmable FPGA for real-time and low-latency processing and a dual-core ARM CPU for stand-alone operation. Users can deploy applications directly on to the preinstalled embedded Linux operating system or stream samples to a host computer using high-speed interfaces such as 1 Gigabit Ethernet, 10 Gigabit Ethernet, and Aurora.

Synchronization

The USRP E320 has a flexible synchronization architecture with support for traditional SDR synchronization methods such as clock reference, PPS time reference, and GPSDO, which enable implementation of high channel count MIMO systems.

Trusted Platform Module (TPM)

The USRP E320 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 E320 is available in two variants:

• Standard variant with TPM (PN 786694-01)
