PXI chassis are the backbone of a PXI system. They physically house PXI modules and controllers, connecting them through a high-performance backplane that provides power, cooling, communication, and advanced timing and synchronization features. PXI chassis ensure your test system is reliable, scalable, and capable of supporting advanced measurement and automation needs.
PXI chassis enable flexible test system design by supporting a wide range of modular instruments so you can tailor configurations to your application needs. The industry-standard, software-connected architecture lets you mix modules, automate measurements, and scale your setup as requirements evolve.
PXI chassis provide stable power and advanced cooling, supporting up to 82 W per slot. They ensure high-performance instruments operate without overheating or power drops, enabling dense test systems to function consistently without manual intervention or extra cooling.
PXI chassis feature integrated timing and synchronization, distributing clocks and triggers for nanosecond-level precision. Achieve repeatable, coordinated measurements across all modules—even in complex, multichassis systems.
The PXI backplane serves as a high-speed data backbone, enabling fast, reliable communication between modules and the system controller. Using PCI Express technology, the backplane transfers data with high bandwidth and low latency for real-time analysis, while hardware synchronization ensures precise, scalable performance.
Scalable PXI chassis models offer from 2 to 18 slots supporting everything from portable and benchtop setups to full rack systems. Flexible form factors and optional hybrid slots enable PXI and PXIe modules in the same system, delivering compatibility, versatility, and growth for any test environment.
