Overview

Product overview

Key product information and technical features.

The USRP-2950 combines reconfigurable radio hardware with a LabVIEW design workflow for prototyping wireless communication systems. NI identifies MIMO, spectrum sensing, cognitive radio, beamforming, and direction finding among its research applications.

NI documents both 40 MHz and 120 MHz USRP-2950 variants. The supplied catalog description identifies 40 MHz, but the model name alone does not distinguish the bandwidth option; verify the unit identification before selecting a configuration.

RF tuning coverage from 50 MHz to 2.2 GHz.
Two transmit channels and two receive channels.
GPS-disciplined oven-controlled reference oscillator for improved frequency accuracy and synchronization.
Reconfigurable architecture for LabVIEW-based wireless system prototyping.
Ethernet and PCI/MXI Express host connectivity documented in NI-USRP 2022 Q4.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

What RF range does the USRP-2950 cover?

The USRP-2950 covers 50 MHz to 2.2 GHz.

Does every USRP-2950 have 40 MHz bandwidth?

No. NI lists separate 40 MHz and 120 MHz variants. This catalog record lists 40 MHz, but its unit-specific bandwidth option still requires confirmation.

Does the USRP-2950 include a GPS-disciplined reference?

Yes. NI specifies a GPS-disciplined 10 MHz oven-controlled crystal oscillator reference clock.

Can the FPGA be modified through an Ethernet connection?

NI-USRP 2022 Q4 states that the FPGA cannot be modified when a USRP-294x/295x device is connected through Ethernet. Plan the host interface around the required FPGA workflow.
