PXI Systems
Build high-performance, mixed-measurement systems with NI’s easy-to-scale PXI platform.
What Is PXI?
PXI is an advanced test and measurement solution that combines hardware and software components, including chassis, controllers, and modules, to tackle complex measurement and automation challenges. Renowned for its flexibility and reliability, engineers use this platform to build high-performance, mixed-measurement systems for validation and production test.
Flexible and Scalable
Delivers unparalleled accuracy, reliability, and timing-sync capabilities, with the ability to synchronize across multiple modules or chassis for system expansion. Customize and scale test systems as tech and requirements change.
High Performance
Experience unparalleled instrument performance, data throughput, and latency throughout your test and measurement applications.
Software Defined
Leverage the platform’s open architecture to develop application-specific measurement and analysis programs using NI LabVIEW, Python, and other languages.
Vibrant Ecosystem
Connect with a global network of vendors, integrators, and consultants for unlimited customization and support.
Customized for Requirements
Why Choose PXI?
PXI offers engineers high performance while reducing test time and cost compared to traditional box instruments. The combination of modularity and software connectivity is ideal for advanced test applications that require precise, large-channel count, mixed-measurement solutions.
Best for:
- Combining instruments, sensor, and electrical measurements
- Production test systems for electronic devices
- Automated validation test
- High-channel, high-speed test applications
PXI System Components
PXI systems are composed of three main hardware components: a chassis, a controller, and modules. System software is customizable and helps you configure, visualize, and automate measurements, analyze your data, and share reports.
Chassis
The chassis is the backbone of a PXI system and is comparable to a PC’s mechanical enclosure and motherboard. It provides power, cooling, and a communication bus to the system, and synchronizes the instrument modules. Chassis range in size from two to 18 slots to fit the needs of your application, whether you require a portable, benchtop, rack-mount, or embedded system.
Controller
NI PXI controllers are either embedded or remote. Embedded controllers contain everything you need to run your PXI system without an external PC, while remote controllers let you control your PXI system from a desktop, laptop, or server computer.
Modules
The chassis is the backbone of a PXI system and is comparable to a PC’s mechanical enclosure and motherboard. It provides power, cooling, and a communication bus to the system, and synchronizes the instrument modules. Chassis range in size from two to 18 slots to fit the needs of your application, whether you require a portable, benchtop, rack-mount, or embedded system.
