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 NI Ettus USRP X410. Instructions on downloading the latest filesystem image and writing it to the X410 is described in the USRP X410 Getting Started Guide.

Note that if you are operating the device in Network Mode, then the versions of UHD running on the host computer and on the NI Ettus USRP X410 device must match.

Device Overview

The NI Ettus USRP X410 is a high-performance, multi-channel software defined radio. The SDR is designed for frequencies from 1 MHz to 7.2 GHz, tunable up to 8 GHz and features a two-stage superheterodyne architecture with 4 independent TX and RX channels capable of 400 MHz of instantaneous bandwidth each. Digital interfaces for data offload and control include two QSFP28 interfaces capable of 100 GbE[1], a PCIe Gen3 x8 [3] interface, as well standard command, control, and debug interfaces: USB-C JTAG, USB-C console, Ethernet 10/100/1000. The USRP X410 is an all-in-one device built on the Xilinx Zynq Ultrascale+ ZU28DR RF System on Chip (RFSoC) with built-in digital up and down conversion and onboard Soft-Decision Forward Error Correction (SD-FEC) IP.

CAD/STP Models

If you want any CAD / STP models beyond those found here, please send an email to Ettus Support at support@ettus.com 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.


FPGA User Modifications

The Verilog code for the FPGA in the NI Ettus USRP X410 is open-source, and users are free to modify and customize it for their needs. However, certain modifications may result in either bricking the device, or even in physical damage to the unit. Specifically, changing the I/O interface of the FPGA in any way, or modifying the pin and timing constraint files, could result in physical damage to other components on the motherboard, external to the FPGA, and doing this will void the warranty. Also, even if the PCIe interface is not being used, you cannot remove or reassign these pins in the constraint file. The constraint files should not be modified. Please note that modifications to the FPGA are made at the risk of the user, and may not be covered by the warranty of the device.

Interfaces and Connectivity

Front Panel

Rear Panel

Ref Clock - 10 MHz

Using an external 10 MHz reference clock, a square wave will offer the best phase noise performance, but a sinusoid is acceptable.

PPS - Pulse Per Second

Using a PPS signal for timestamp synchronization requires a square wave signal (a typical PPS signal has a 20%-25% duty cycle) with a 5Vpp amplitude.

To test the PPS input, you can use the following tool from the UHD examples:

  • <args> are device address arguments (optional if only one USRP device is on your machine)
   cd <install-path>/lib/uhd/examples ./test_pps_input –args=<args>

Data Throughput Rates

Testing was completed with the following conditions

Executing benchmark_rate over multiple iterations as well as over an extended continuous time period (>12 Hours) without data loss resulted in the following maximum rates and channel counts

  • Usage of the --priority argument set to high in benchmark_rate which requires benchmark rate to be executed with root privileges via sudo
  • Usage of single versus multiple threads in the benchmark_rate utility - controlled by using the --multi_streamer argument. Specifying this argument assigns one thread per channel being streamed.
  • Utilizing the CG_400 bitfile which does not include DUC/DDC resampling thus supports only rates of 491.52 MS/s and 500 MS/s
  • Dual Port DPDK
    • 4 Rx + 4 Tx @ 491.52 MS/s
    • 4 Rx @ 491.52 MS/s

Guidance on SFP+ Adapters for Fiber Connectivity on NI Ettus USRP X410

Ettus Research currently offers direct-connect, copper cabling accessories for the NI Ettus USRP X410. 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 NI Ettus USRP X410 is compatible with most brands of SFP+ fiber adapters. In some cases, other equipment in the systems such as 1/10/100 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 NI Ettus USRP X410 devices with our TBD. Here are is a list of known-good cables and adapters.

Ettus Research has only tested multi-mode fiber accessories.
