Why PXI

PXI is the de facto standard for automated test

Compared with traditional rack-and-stack box instruments, PXI reduces cabling, improves synchronization, increases test density, and makes automation easier.

Overview

Built for testing today’s complex systems

PXI combines modular instrumentation, high-speed data movement, precision timing, software-defined control, and a broad multi-vendor ecosystem within a single standard. That makes it ideal for testing today’s complex electronic systems.

Capabilities

What makes PXI powerful

01

Tight synchronization

Built-in timing and triggering synchronize instruments without complex external cabling

02

Smaller Size

High-density modular instruments reduce rack space and simplify system design, without sacrificing accuracy

03

Software-defined

Software is at the core of a PXI System. It configures hardware, executes test sequences, processes data, and monitors system performance

04

Long-term Scalability

Reusable modules with long lifecycles scale across products, stations, and sites

05

High-speed Data Movement

Increase throughput with high-speed data transfer between modules and systems

06

A Complete Ecosystem

A thriving market of interoperable instruments, switching, software, interconnects, and services

Comparison

PXI: A Better Approach

Box instruments are excellent tools. They are familiar, powerful, and often ideal for benchtop debugging, interactive measurements, and smaller test setups.  But box instruments are usually optimized as individual instruments, even when connected together over communication standards such as LXI.

PXI is optimized for automated test.

Performance

Box: High accuracy. Slower throughput due to message-based communication.
PXI: High accuracy and speeds. DC to RF.

Breadth of instrumentation

Box: Enormous number of options in all shapes and sizes.
PXI: Multi-vendor open standard. Very large number of instrument options.

Synchronization

Box: Possible through LXI and external cabling.
PXI: Built-in backplane triggers and reference clocks.

Footprint

Box: Large.
PXI: Compact.

Channel density

Box: Low, at a system level.
PXI: High, across many instrument types.

Software automation

Box: Possible, but optimized for manual operation.
PXI: Core design principle.

Reuse across programs

Box: Possible, but major rework often required.
PXI: Modules, software, and architecture can be readily reused.

Cost

Total Cost of Ownership

The purchase price of instruments is only part of the cost of a test system.

The bigger costs often appear later: integration time, cabling, debugging, downtime, manual setup, inconsistent configurations, duplicated software, difficult replication, poor reuse, and slow adaptation when requirements change.

PXI helps reduce these hidden costs by giving test engineers a standard for system design. A well-architected PXI system can shorten development time, improve repeatability, reduce rack space, simplify synchronization, and make it easier to deploy similar systems across teams and sites.

That is why PXI is often chosen not just for performance, but for long-term test strategy.

Strategy

From one test station to a test strategy

PXI helps test departments move from isolated test setups to a common automated test platform. That platform can support design validation, production test, regression systems, repair and depot test stations, and future product generations.

What PXI enables
  • For test engineers, PXI reduces friction.
  • For test managers, PXI improves reuse and standardization.
  • For manufacturers, PXI supports throughput, repeatability, and deployment at scale.
  • For organizations, PXI turns test from a cost center into a strategic advantage.
Build

Build with the PXI ecosystem

PXI is an open standard supported by companies across the automated test industry. PXISA members provide the hardware, software, interconnect, services, and expertise needed to build complete test systems.

Whether you are validating a new design, modernizing a production line, or creating a platform for future products, PXI gives you a proven foundation for automated test.
