Overview

Product overview

Key product information and technical features.

This module provides the programmable FPGA portion of a modular FlexRIO system. An attached adapter module determines the physical inputs and outputs, allowing the FPGA processing hardware and signal interface to be selected separately.

NI lists PXI-7952 as the product model on its certification page and PXI-7952R in the associated hardware description. The catalog model name is retained here; use PXI-7952R when locating the module in NI's installation guide and FPGA resource tables.

Virtex-5 LX50 FPGA with 7,200 FPGA slices.
48 DSP48 slices and 1,728 kbit embedded block RAM.
Two 64 MB DRAM banks, each with an 800 MB/s maximum theoretical bandwidth.
Modular I/O architecture with a separate FlexRIO adapter module.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Why does NI documentation use PXI-7952R?

NI's PXI-7952 certification page identifies the associated hardware as PXI-7952R. The installation guide also uses PXI-7952R; this card preserves the catalog name PXI-7952.

How much onboard DRAM does the module provide?

It provides 128 MB, organized as two 64 MB banks.

Does the FPGA module alone define the measurement I/O?

No. In this modular FlexRIO architecture, the adapter module defines the physical inputs and outputs.
