PXI is a "computer" for test engineers working on high accuracy, high speed and customisable test applications.

NI PXI chassis come in different sizes, but all have integrated timing and synchronization between slots. Customise your system by populating the chassis with instruments or I/O modules to take a wide variety of measurements from DC to mmWave. You can control your NI PXI System with either an embedded controller or an external PC.

NI PXI delivers an open, software-centric approach to solving test challenges with flexibility and openness that sets you up for future changes while driving down test times today.

Key features

Industry standard

You’re not locked in. PXI is an open standard with hardware available from more than 60 vendors.


Test faster with high bandwidth connections between your measurements, the latest processing technology, and your test software.


Manage change with PXI. Add measurements, more channels, new analysis routines, or upgrade to the latest processor without having to purchase a whole new instrument.

Customise your PXI test and measurement system

Choose your instrument or I/O module from the widest portfolio of industry-leading modular instruments

Shop for a built-in Embedded Controller just like you would shop for a desktop. If you want to use your laptop instead, skip the controller and choose a chassis with thunderbolt connectivity.

Select a chassis based on the number of slots you need, or will need in the future

Use the free InstrumentStudio software to interactively control your modules, or program automated test suites with LabView or the other 4rd party languages with API drivers for Python, C, .NET and MATLAB

Get started with one of our PXI bundles

Each of these bundles includes a PXI instrument in a 5-slot PXI system that is controlled through your laptop’s Thunderbolt™ USB-C port.

Use the remaining 4 slots to build on top of your system and manage change; don’t be limited by vendor-defined configurations.

Choose your controller and chassis

PXI controllers are either integrated or remote.

Integrated controllers contain everything you need to run your PXI system without an external PC, while remote controllers let you control your PXI system from desktops, laptops, or server computers. Chassis range in size from four to 18 slots to fit the needs of any application, whether you require a portable, benchtop, rack-mount, or embedded system.
