E320

Device Overview

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 2x2 MIMO AD9361 transceiver from Analog Devices, which covers frequencies from 70 MHz – 6 GHz and provides up to 56 MHz of instantaneous bandwidth.

Frontend Specifications

Tuning

The RF frontend has individually tunable receive and transmit chains. Both transmit and receive can be used in a MIMO configuration. For the MIMO case, both receive frontends share the RX LO, and both transmit frontends share the TX LO. Each LO is tunable between 50 MHz and 6 GHz.

Gains

All frontends have individual analog gain controls. The receive frontends have 76 dB of available gain; and the transmit frontends have 89.8 dB of available gain. Gain settings are application specific, but it is recommended that users consider using at least half of the available gain to get reasonable dynamic range.

Guidance on SFP+ Adapters for Fiber Connectivity on USRP E320

Ettus Research currently offers direct-connect, copper cabling accessories for the USRP E320. However, it is also possible to use multi-mode fiber instead of copper connections for these devices. In this section, we will provide general guidance on the types of fiber adapters and cables that can be used with these products.

The USRP E320 USRP is compatible with most brands of SFP+ fiber adapters. In some cases, other equipment in the systems such as 1/10 Gigabit Ethernet switches are only compatible with specific brands of SFP+ adapters and cables. As a general rule, we recommend checking compatibility with the switches and network cards in your system before purchasing an adapter.

Ettus Research does test the USRP E320 USRP devices with our 10 Gigabit Ethernet Connectivity Kit and a Blade Networks G8124 1/10 GigE switch. Here are is a list of known-good cables and adapters.

Ettus Research has only tested multi-mode fiber accessories.

Known-Good Adapters

• Approved Optics BN-CKM-SP-SR-A

Known-Good Cables

• Elpeus 10GbE SFP+ AOC Cable, 3 meters

Guidance on 10Gb SFP+ to RJ45 Adapters

Many new motherboards come equipped with an onboard 10Gb RJ45 NIC. It is possible to use a SFP+ to RJ45 adapter and operate at 10Gb speeds using a Cat6/7 Ethernet cables.

Ettus Research has tested the adapters linked below.

Known-Good Adapters

• 10Gtek SFP+ to RJ45 Copper Module
• ProLabs 10G-SFPP-T-C
