Notice
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 X4x0. Instructions on downloading the latest filesystem image and writing it to the X4x0 are described in the USRP X4x0 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 X4x0 device must match.
Device Overview
X440
The NI Ettus USRP X440 is the widest bandwidth USRP software defined radio device. It differs architecturally from most USRPs, utilizing a direct sampling architecture that provides balun-coupled access to the ADCs and DACs on the onboard Xilinx Zynq RFSoC. This makes it well suited to use as an intermediate frequency transceiver, connecting to external front ends for applications like satellite communications (SATCOM) prototyping, SATCOM ground station deployment, and mmWave or sub-THz 6G research. USRP X440 features high channel density – 8 Tx and 8 Rx channels per device – with phase coherency across channels by sharing sample clocks. Therefore, it is ideal for applications like direction finding and radar research and prototyping.

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
FPGA User Modifications
The Verilog code for the FPGA in the NI Ettus USRP X4x0 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
X440
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 5 Vpp 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>

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
--priorityargument set tohighin benchmark_rate which requires benchmark rate to be executed with root privileges viasudo - Usage of single versus multiple threads in the benchmark_rate utility - controlled by using the
--multi_streamerargument. Specifying this argument assigns one thread per channel being streamed. - Utilizing the CG_400 and CG_1600 bitfile.
- CG_400
- Dual Port DPDK
- 6 Rx @ 500 MS/s
- 8 Rx @ 400 MS/s
- 6 Tx @ 500 MS/s
- 8 Tx @ 450 MS/s
- 4 Rx + 4 Tx @ 500 MS/s

All testing was done using dual 100GbE ports. For a single port, expect around half the number of channels as compared to the dual port equivalent configuration at the same streaming rate.
Guidance on SFP+ Adapters for Fiber Connectivity on NI Ettus USRP X4x0
Ettus Research currently offers direct-connect, copper cabling accessories for the NI Ettus USRP X4x0. 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 X4x0 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 X4x0 devices with the listed hardware as noted in the above section https://kb.ettus.com/X440#100_Gigabit_Ethernet
