PXI Chassis

PXI Chassis

PXI Chassis are the foundation of PXI and PXI Express modular test systems, providing power distribution, cooling, timing synchronization, and high-speed communication between PXI controllers and measurement modules.

PXISOURCE provides National Instruments PXI and PXIe Chassis for automated testing, data acquisition, RF measurement, semiconductor validation, aerospace testing, hardware-in-the-loop simulation, and laboratory measurement applications.

What Is a PXI Chassis?

A PXI Chassis is a modular hardware platform designed to install and connect PXI, PXI Express, and hybrid PXI modules. It provides the mechanical structure, power supply, system clock, trigger routing, and backplane communication required for a complete PXI test system.

Compared with traditional standalone instruments, PXI Chassis allow engineers to integrate multiple measurement functions into a single synchronized platform, improving system flexibility, scalability, and test efficiency.

Types of NI PXI Chassis

PXI Express Chassis

PXI Express Chassis use PCI Express-based backplane technology to provide high-speed communication between controllers and PXIe modules. They are designed for applications requiring large data throughput, advanced synchronization, and high-performance measurement.

Popular PXI Express Chassis include PXIe-1085, PXIe-1086, PXIe-1090, PXIe-1092, and PXIe-1095.

PXI Hybrid Chassis

PXI Hybrid Chassis support both PXI and PXI Express modules, allowing engineers to combine legacy PXI instruments with newer PXIe technologies in the same test platform.

Hybrid chassis solutions provide a flexible upgrade path for existing PXI systems while maintaining compatibility with installed measurement hardware.

Common hybrid chassis include PXIe-1075, PXIe-1078, and PXIe-1082.

High-Performance PXI Chassis

High-performance PXI Chassis are designed for demanding applications requiring high module density, improved cooling capability, large system bandwidth, and precise timing synchronization.

These chassis are commonly used in RF testing, semiconductor characterization, high-speed digitizer applications, and large automated test systems.

Typical models include PXIe-1086 and PXIe-1095.

Legacy PXI Chassis

Legacy PXI Chassis remain widely used in existing automated test and measurement systems where compatibility with installed PXI modules is required. They are suitable for system maintenance, upgrades, and long-term industrial applications.

Popular legacy models include PXI-1042, PXI-1045, and PXI-1036.
