NI PXIe-8881 4-Core

NI PXIe-8881 4-Core is the Intel Xeon W-2225 configuration of the National Instruments PXIe-8881 embedded controller family. This 4-core version has a 4.1 GHz nominal processor frequency and 16 GB of standard memory in the NI controller comparison guide. It supports processor-based test system control within a compatible PXI Express chassis, combining modular instrumentation control and front-panel computing connections. The processor core count describes a catalog configuration, not independent proof of the CPU installed in any photographed inventory unit.

Overview

Product overview

Key product information and technical features.

The PXIe-8881 4-Core uses Intel Xeon W-2225 processor hardware. NI reports a 4.1 GHz nominal processor frequency and 16 GB standard memory for this CPU option. The comparison guide lists a 24 GB/s PXI system bandwidth figure for the PXIe-8881 family. Memory and storage offered with an individual secondhand unit may differ from the standard catalog configuration. Check the actual installed memory, storage, OS image, and configuration label before an order is placed.

The quad-core configuration is one of three supported CPU versions and should be selected by checking the expected test software workload against the chassis and instrument requirements. The official Getting Started guide requires a PXI Express chassis that provides 82 W per-slot cooling capacity. Before inserting a controller, power down the system and follow NI electrostatic-discharge and installation precautions. This is not a standalone desktop computer or a generic PXIe measurement module.

The manufacturer documents two Gigabit Ethernet ports, four USB 2.0 ports, two USB 3.x Gen 1 ports, and two Thunderbolt 3 connections for the PXIe-8881 family, together with display and serial connections. The exact front panel, BIOS support, OS license, recovery media, accessories and security module are subject to individual configuration. A processor name alone does not establish installed software, OS support, tested condition or calibration history.
