GPIB Interface Cards | Modular Instrument System

GPIB interface cards for reliable use of existing test instruments

Easily integrate GPIB into modern test systems

With GPIB interface cards (IEEE-488) you connect existing test and measurement instruments such as power supplies, electronic loads, multimeters, LCR meters or safety testers to PC-based test systems. You control all instruments centrally from your test software and acquire measurement data automatically – ideal for laboratory, development, quality assurance and production without having to replace proven equipment.

Benefits and typical applications

GPIB interface cards automate recurring measurement sequences, reduce manual operating errors and increase repeatability and throughput. Typical applications include functional testing of electronic assemblies, end-of-line test stands, long-term tests and flexible lab setups. GPIB is particularly useful when many existing benchtop instruments are to remain in use and still be integrated into structured, software-controlled test processes.

Functions and variants

In the “Interface cards – GPIB” category you will find suitable solutions for different system architectures:

• GPIB-USB adapters for quick connection to a PC or notebook
• GPIB-LAN converters for integration into Ethernet or LXI networks

This allows you to connect individual instruments or entire instrument groups flexibly to your PC or network infrastructure and to integrate GPIB instruments into hybrid LXI/PXI test environments when required.

Advantages of GPIB interface cards from LXinstruments

GPIB has been established in laboratory and production environments for many years and is supported by a wide range of instruments. With suitable interface cards you expand your test systems step by step, continue to use existing equipment and combine it with modern LXI or PXI technology. LXinstruments offers a coordinated portfolio and consulting by experienced test and measurement specialists – from selection through to integration.

FAQ on GPIB interface cards

What is GPIB?

GPIB (General Purpose Interface Bus, IEEE-488) is a digital interface that allows test and measurement instruments to exchange data with a controller – usually a PC – in a standardised way.

What do I use GPIB interface cards for?

You use GPIB interface cards to integrate existing GPIB instruments into PC-based test systems or networks and to control them centrally via test software.

How many instruments can I control via GPIB?

A GPIB bus can host several instruments with their own addresses. A GPIB controller can address these instruments one after another and operate them in automated test sequences.

What is the difference between GPIB-USB, GPIB-LAN and PCIe-GPIB?

GPIB-USB is suitable for quickly connecting individual instruments to a PC or notebook. GPIB-LAN integrates instruments into an Ethernet or LXI network. PCIe-GPIB cards embed the interface permanently in an industrial PC or rack controller.

Can I combine GPIB with LXI or PXI systems?

Yes. In many test systems GPIB, LXI (LAN) and PXI operate in parallel. This lets you continue to use classic GPIB instruments while adding modular, network-capable components.

Does LXinstruments support the selection of a suitable GPIB solution?

Yes. The LXinstruments team supports you in selecting suitable GPIB interface cards and adapters and in integrating them into new or existing test stands.

Integrate GPIB interface cards into your test system now

You want to continue using your existing GPIB instruments and at the same time automate or modernise your test processes? With GPIB interface cards and adapters from LXinstruments you bridge the gap between proven instrumentation and modern PC-based, LXI or PXI test systems. You control instruments centrally, capture measurement data directly in the system and adapt test sequences quickly to new products or standards – without having to redesign your entire instrument setup.
