NI PXIe-8881 18-Core

NI PXIe-8881 18-Core is the Intel Xeon W-2295 configuration of the National Instruments PXIe-8881 embedded controller family. This 18-core version has a 3.0 GHz nominal processor frequency and 64 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 18-Core uses Intel Xeon W-2295 processor hardware. NI reports a 3.0 GHz nominal processor frequency and 64 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 eighteen-core configuration has the largest core count of the three NI PXIe-8881 processor selections; the actual workload benefit depends on the software and instruments involved. 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.
