Device Overview

The Ettus Research USRP X310 is a high-performance, scalable software defined radio (SDR) platform for designing and deploying next generation wireless communications systems. The hardware architecture combines two extended-bandwidth daughterboard slots covering DC – 6 GHz with up to 120 MHz of baseband bandwidth, multiple high-speed interface options (PCIe, dual 10 GigE, dual 1 GigE), and a large user-programmable Kintex-7 FPGA in a convenient desktop or rack-mountable half-wide 1U form factor.

USRP™ X300 and USRP™ X310 SDRs Frequently Asked Questions

  • What is the bandwidth of the USRP X300/X310

The ADC rate on each analog RX channel is 200 MS/s quadrature, which provides a theoretical analog bandwidth of approximately 80% of the Nyquist bandwidth of +/- 100 MHz (+/- 80 MHz around the center frequency). The resulting maximum theoretical analog bandwidth is 160 MHz. The actual analog bandwidth may be reduced due the RF daughterboard selected.

RF Daughterboard Bandwidths: See the daughterboard specifications [link]

FPGA Processing Bandwidth: Up to 200 MS/s quadrature.

Host Bandwidth: Up to 200 MS/s quadrature, dependent on selected interface

For more information about achieving the maximum bandwidth with a USRP X300/X310, please see the "USRP X300/X310 Configuration Guide" or the "USRP System Bandwidth" application note.

  • How can I program the USRP X300/X310

Like all other USRP models, the USRP X300 and X310 are compatible with the USRP Hardware Driver™ (UHD) architecture. The UHD architecture is a common driver that allows users to develop and execute applications on a host-PC. UHD provides a direct C++ API to control and stream to/from the USRP X300/X310. It also provides compatibility with a variety of third-party software frameworks including GNU Radio, Labview, and Matlab. You may also customize the FPGA image provided with UHD to integrate your own signal processing. For more information about UHD, and supported software frameworks, please see:

http://files.ettus.com/manual/

  • How do I update the FPGA images and firmware with the latest from UHD

You can find more information about updating the FPGA image through PCIe, 1/10 GigE, and JTAG here.

  • How can I modify the FPGA of the USRP X300/X310

The source code (Verilog) for the USRP X300/X310 is available in the UHD repository. The USRP X300/X310 requires ISE 14.4 or newer. The build process leverages the existing CMAKE build system used to compile the host-side driver. A Linux-based setup will provide the best results.

  • How much free space is available in the USRP X300/X310 FPGA

Please see the USRP X300/X310 FPGA resources page for more information.

  • What type of PC setup is recommended for use with the USRP X300/X310

The type of PC required depends heavily on the complexity and bandwidth of the application. To demonstrate the USRP X300/X310, we typically use a desktop computer with a quadcore i7, 8+ GB of DDR3, and install the PCIe interface card that is also provide with the 10 GigE, PCIe, and ExpressCard interface kits.

  • What frequency range does the USRP X300/X310 cover

The frequency range depends on the daughterboard select by the users. For more information, please see the USRP X300/X310 Configuration Guide.

  • What components do I need to purchase for a complete USRP X300/X310 system

For a more comprehensive guide, please see the USRP X300/X310 Configuration Guide.

  • What is the difference between the USRP X300/X310

The USRP X310 includes a larger Kintex-7 series FPGA (XC7K410T) with additional development resources for more complex designs. The USRP X300 includes the smaller XC7K325T FPGA.
