Overview

Product overview

Key product information and technical features.

Designed for over-the-air acquisition and analysis, the USRP-2955 uses a two-stage superheterodyne receiver architecture. Shared local oscillators support phase-coherent operation across its four independent receive channels.

The USRP RIO programming workflow supports NI-USRP applications and custom LabVIEW FPGA development. FPGA programming requires the PCIe x4 connection rather than Ethernet.

  • Four-channel, receive-only RF acquisition.
  • 80 MHz instantaneous bandwidth throughout the tuning range of each receiver path.
  • Receiver gain adjustable from 0 to 95 dB in 1 dB steps.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Can the USRP-2955 transmit RF signals?

No. It has four RF input channels and zero RF output channels.

Is the 80 MHz bandwidth shared between the receivers?

NI specifies 80 MHz instantaneous bandwidth for each receiver path throughout the device's frequency range.

Can the FPGA be programmed over Ethernet?

No. NI requires the PCIe x4 connector for FPGA programming.
