Overview

Product overview

Key product information and technical features.

The USRP-2952 belongs to the USRP RIO platform. NI identifies its architecture as X310 with SBX RF hardware and GPSDO, distinguishing it from USRP models with different RF front ends.

Host connection options include Ethernet and PCI/MXI Express x4. NI-USRP 19.5 documents both bandwidth variants as supported hardware; software and FPGA workflows depend on the selected connection and software version.

Dual transmit and dual receive RF paths.
GPSDO supports GPS-referenced clock locking, timing synchronization, and location queries.
USRP RIO architecture with a programmable FPGA.
1 GbE and 10 GbE support through the device's rear-panel connections.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does every USRP-2952 have the same bandwidth?

No. NI documents 40 MHz and 120 MHz versions. This catalog record describes 40 MHz, but the exact unit variant requires confirmation.

What does the built-in GPSDO provide?

It enables clock locking to a GPS reference, GPS timing synchronization, and GPS location queries.

Is the USRP-2952 supported by NI-USRP?

NI-USRP 19.5 explicitly lists both USRP-2952 bandwidth variants. This is version-specific evidence, not a claim of support across every driver, operating system, or LabVIEW release.
