SAN DIEGO, CA — September 16, 2026
National Instruments (NI) released the NI Ettus USRP B310, a new addition to their USRP platform of software-defined radios. This release delivers wider frequency coverage, increased channel density, and GPU coprocessing integration within their entry-level USRP series.
The NI Ettus USRP B310 brings frequency coverage, bandwidth, and multi-device scalability to teams needing real capability without a high price of entry:
350 MHz – 7.2 GHz frequency range across 2 TX / 2 RX channels
Up to 100 MHz of bandwidth per channel
Up to 4 units can be synchronized into an 8x8 channel system, no external clocking hardware required
Three form factors: OEM board, PCIe card, and a fully enclosed benchtop unit
PCIe variant supports high-bandwidth GPU co-processing, compatible with platforms like NVIDIA
“The B310 is our first new entry-level USRP in a decade. We’re excited to refresh our platform with solid performance at a competitive price point." - Sarah LaSelva, Chief Product Marketing Manager, NI/Emerson Test & Measurement Business Unit
With these specifications and price point, the B310 is a strong fit for applications such as spectrum sensing, direction finding, signal design prototyping, and wireless research & teaching labs.
USRP B310 PCIe variant
The NI Ettus USRP B310 is available in three form factors:
790817-01:Â PCIe card
790415-01:Â Board only, with PCIe bus connectivity
790414-01:Â Enclosed Thunderbolt 3 desktop

NI Ettus USRP B310 - FAQ
Q: What is the NI Ettus USRP B310?
A: The NI Ettus USRP B310 is a scalable, entry-level software-defined radio (SDR) designed for applications from research through deployment.
Q: What is the frequency range and bandwidth of the USRP B310?
A: The USRP B310 has a frequency range of 350 MHz to 7.2 GHz, with up to 100 MHz of bandwidth per channel.
Q: How many TX/RX channels does the USRP B310 have?
A: The USRP B310 has 2 transmit and 2 receive channels, with 2 independent local oscillators (LOs), so each transmit/receive chain can be tuned independently.
Q: Can multiple USRP B310 units be synchronized together?
A: Yes. Up to four USRP B310 units can be synchronized to create an 8x8 channel system that doesn't require external clocking hardware.
Q: What form factors is the USRP B310 available in?
A: The USRP B310 is available in three configurations:
A PCIe plug-in card (790817-01)
An OEM board, with PCI Express (PCIe) bus connectivity (790415-01)
An enclosed desktop unit with Thunderbolt 3 bus connectivity (790414-01)
Q: What software is the USRP B310 compatible with?
A: The USRP B310 comes with UHD driver support, like all NI/Ettus USRPs. The UHD driver is compatible with C, C++, Python, and GNU Radio, with additional support for LabVIEW.
Q: What applications is the USRP B310 used for?
A: The USRP B310 could be used for applications like RF research and spectrum sensing.
Q: How does the USRP B310 compare to the USRP B200, B210, and B206mini?
A: The USRP B310 offers more bandwidth (100 MHz) and wider frequency coverage (up to 7.2 GHz) than the USRPs B200/B210/B206mini, which top out at 6 GHz and 56 MHz of bandwidth.
Q: Where can I get the NI Ettus USRP B310?
A: The USRP B310 is available through Cyth Systems, a National Instruments technical distributor and system integratorhttps://www.cyth.com/products/usrp-b310-790414-01
