USRP 2945

What is the USRP-2945?

The USRP-2945 is a high-performance hardware and software integrated SDR (Software Defined Radio) receiver device from National Instruments (NI) that covers the frequency range of 10 MHz ~ 6 GHz, supports real-time bandwidths of up to 80 MHz, and has four independent receiver channels for local oscillation coherent (LO)-shared synchronous reception. Shared (LO-shared) synchronous reception.

It is based on the USRP X310 motherboard with two sets of TwinRX RF daughterboards and a Kintex-7 FPGA, which can be programmed directly using the LabVIEW FPGA module. It excels in application scenarios such as spectrum monitoring, direction finding, signal intelligence, wide-area recording, radar prototyping, and more!

How the USRP-2945 Relates to the X310 Series

The USRP-2945 is essentially a pre-assembled unit of the X310 motherboard with a TwinRX front end, and NI provides complete unit delivery, including hardware assembly and factory testing. Compared to the modular Ettus X310, the USRP-2945 eliminates the need for user parts, assembly and testing.


Quick Start Guide

5.1 Installation and Driver Configuration

Use either the NI-USRP or open source UHD driver, which supports LabVIEW, GNU Radio, and more.

Follow the “Getting Started Guide” to complete the USB/Ethernet connection and device identification test.

5.2 Example Project Practice

Start a spectrum scanning or continuous reception project to verify the synchronization of four channels.

Run the Rx Continuous Async example in LabVIEW environment to confirm the reception is working properly.

5.3 FPGA and Signal Acquisition Optimization

Adjust sample rate, filter, gain, and other parameters in LabVIEW or UHD to ensure signal quality.

FPGA logic can be written to realize real-time preprocessing, spectrum analysis, signal recognition and other enhanced functions.
