When you receive a brand-new device, it is strongly recommended that you download the most recent filesystem image from the Ettus Research website and write it to the SD card that comes with the unit. It is not recommended that you use the SD card from the factory as-is. Instructions on downloading the latest filesystem image and writing it to the SD card are listed below.

Note that if you are operating the device in Network Mode, then the versions of UHD running on the host computer and on the USRP N300/N310 device must match.

Device Overview

The USRP N310 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 debugging, updating software, rebooting, factory resetting, self-testing, and monitoring system health. The USRP N310 is an all-in-one device that includes two AD9371 transceivers, the Zynq-7100 SoC baseband processor, two SFP+ ports, a built-in GPSDO module, and various other peripheral and synchronization features.

You must use either the Level VI Efficiency power supply provided in the shipping kit, or another UL listed ITE power supply marked LPS, with the USRP N310.

Input voltage: 12 VDC Input current: 7.0 A, maximum Typical power consumption: 50 W to 80 W, varies by application Hardware Specifications Ettus Research recommends to always use the latest stable version of UHD If you need to clean the module, wipe it with a dry towel. N310 Current Hardware Revision: D Minimum version of UHD required: 3.11.0.0 Due to product compliance restrictions on products with TPM (Trusted Platform Module) components to a few countries, the USRP N310 is available in two variants: Standard variant with TPM (P/N 785067-01) Non-TPM variant (P/N 786465-01) Clocking and Sampling Rates

There are three master clock rates (MCR) supported on the N310: 122.88 MHz; 125.0 MHz; 153.6 MHz.

The sampling rate must be an integer decimation rate of the MCR. Ideally, this decimation factor should be an even number. An odd decimation factor will result in additional unwanted attenuation (roll-off from the CIC filter in the DUC and DDC blocks in the FPGA). The valid decimation rates are between 1 and 1024.

For the MCR of 122.88 MHz, the achievable sampling rates using an even decimation factor are 122.88, 61.44, 30.72, 20.48, 15.36, 12.288, 10.24, 8.777, 7.68 Msps, ... 120.0 Ksps.

For the MCR of 125.0 MHz, the achievable sampling rates using an even decimation factor are 125.0, 62.5, 31.25, 20.833, 15.625, 12.5, 10.41666, 8.9286 Msps, ... 122.07 Ksps.

For the MCR of 153.6 MHz, the achievable sampling rates using an even decimation factor are 156.3, 78.15, 39.075, 26.05, 19.5375, 15.63, 13.025, 11.16429 Msps, ... 152.637 Ksps

If the desired sampling rate is not directly supported by the hardware, then it will be necessary to re-sample in software. This can be done in C++ using libraries such as Liquid DSP [1], or can be done in GNU Radio, in which there are three blocks that perform sampling rate conversion.

If you want any CAD / STP models beyond those found here, please send an email to Ettus Support at [email protected] noting your request and your use case for any such model. We will determine on a case-by-case basis whether we have any such requested model and, if so, whether to release it -- possibly requiring an NDA for any such release. Note that we do not have models on all USRPs and daughterboards, and requesting any model does not guarantee that either Ettus Research or NI will honor any such request.
