Interface Cards - PCI

PCI interface cards for expanding PC test systems

Upgrade a PC into a powerful test bench

With PCI and PCIe interface cards, you turn a standard or industrial PC into a high-performance test system. The cards integrate measurement, switching, and I/O functions directly into the computer and replace many standalone bench instruments. This enables automated tests in development, validation, and production—space-saving, flexible, and future-proof.

Benefits and typical applications

PCI interface cards are suitable wherever you need to acquire, stimulate, or switch signals:

• Functional testing of electronic assemblies
• End-of-line test stands
• Quality assurance
• Laboratory setups and endurance tests

Direct PC integration ensures structured test sequences, tidy cabling, and a maintenance-friendly system architecture. You implement changes to test steps or products primarily in software.

Functions and module types

In this category you will find, among others:

• Multifunction cards for combined measurement and control tasks
• Digital I/O, counter, and timing cards
• Arbitrary and signal generator cards for flexible test signals
• High-voltage switching and matrix solutions for complex switching paths on the DUT
• Interface and bus expansion cards for connecting external racks and instruments

By combining these module types, you configure exactly the functionality your application needs—from a single test station to a PC-based test system.

Advantages for development and manufacturing

PCI interface cards are based on established PC standards and offer strong investment protection. With these cards, you expand your system step by step, continue using your existing IT infrastructure, and combine PCI/PCIe modules with LXI or PXI components as required. LXinstruments supports you with a coordinated portfolio and consulting from experienced test and measurement specialists.

FAQ about PCI interface cards

What is a PCI interface card?

A PCI interface card is a plug-in PC card that provides additional measurement, switching, I/O, or communication functions and purposefully turns the computer into a test or automation system.

What is the difference between PCI and PCIe?

PCI is based on a parallel bus system. PCI Express (PCIe) is serial and designed for higher data rates. Both standards are suitable for test systems; PCIe offers headroom for data-intensive applications.

What does cPCI mean?

cPCI (CompactPCI) is an industrial standard for modular computer systems in which individual CompactPCI modules are installed in a robust 19" rack. Electrically, cPCI is based on the well-known PCI bus, but it is mechanically more robust and designed for continuous operation in industrial environments.

What is meant by External PCI or External PCIe?

External PCI/PCIe refers to a technique where expansion cards are operated in an external enclosure rather than inside the PC. The connection is made via a special cable, so the system recognizes the external cards as if they were internal—ideal when more slots or specialized hardware are needed outside the computer.

Which applications are PCI interface cards suitable for?

Typical use cases include functional testing of electronic assemblies, end-of-line test stands, lab and development tests, quality assurance, and automated measurement stations in production.

Can I continue using existing instruments?

Yes. With suitable interface and bus expansion cards, you connect existing instruments or PXI/LXI components to the PC and combine them with functionally matched PCI/PCIe modules.

How do I find the right PCI interface card?

Start with your test steps: Which signals must be measured, switched, or generated? Based on function and interface, select suitable cards in the online shop—LXinstruments Support will assist you if needed.

How does LXinstruments support PCI-based test systems?

LXinstruments supports you from selecting individual cards to designing complete PC-based test systems—including concept, integration into existing equipment, and future expansion.
