Overview

Product overview

Key product information and technical features.

Part of NI's USRP RIO platform, the USRP-2953 integrates RF hardware with the LabVIEW reconfigurable I/O architecture for developing and evaluating wireless communication systems.

NI documents separate 40 MHz and 120 MHz versions. The supplied catalog description identifies 40 MHz bandwidth, but the model name alone does not distinguish these versions; confirm the hardware variant before selecting a bandwidth-dependent configuration.

  • Reconfigurable USRP RIO architecture for LabVIEW-based wireless prototyping.
  • GPS-disciplined reference supports synchronization for distributed radio research.
  • Ethernet operation supports both 1 GbE and 10 GbE with the documented FPGA image configuration.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the USRP-2953 include GPS-disciplined timing?

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

Is every USRP-2953 a 40 MHz device?

No. NI documents 40 MHz and 120 MHz versions. This catalog record states 40 MHz, but its exact hardware variant requires confirmation.

Can the FPGA be modified over Ethernet?

No. The NI-USRP 2023 Q3 documentation states that FPGA modification is unavailable when USRP-294x/295x devices are connected through Ethernet.
