In every lab, there’s a familiar struggle: tangled cables, scattered instruments, and hours lost to setup. The Accordion Tailored Test System was created to change that. Built on the proven Accordion Agent platform, this service gives you a modular, scalable, and fully customisable test system — designed to fit your product, your process, and your pace.
Whether you’re in R&D, QA, or production testing, Accordion helps you move faster and cleaner. It reduces the number of instruments on your bench, simplifies connections, and cuts setup time dramatically. You get a system that’s not only tailored to your device under test, but also to your workflow — from hardware to software.
And if your needs go beyond what’s off the shelf? We’ll build what’s missing. Custom modules, tailored connectors, and Expand units are all part of the offer. Because we believe test systems should adapt to you — not the other way around.

Do you have an idea for how Accordion can help you streamline your testing? Connect with us now!

Based on Accordion Agent

At the heart of every tailored system is the Accordion Agent — a modular, high-performance test controller with a proven track record. It features a robust base unit with four I/O module slots, two power/load slots, and support for multiple communication buses. With a wide range of existing modules and Expand units, we can configure a powerful system from day one — and then tailor it to your exact needs.

Tailored Connections and Communication Buses

Every product is different. That’s why Accordion Agent features a modular top plate where we can tailor the physical connectors and communication interfaces to your specific requirements. Whether you’re working with CAN, LIN, UART, Ethernet, or something more exotic — we can streamline the interface to match your devices and instruments, reducing clutter and setup time.

Tailored Modules

Accordion Agent supports four SO-DIMM slots for I/O modules and two for power and load. You can choose from our existing library of modules — or we can develop a custom one for your application. Whether you need high-speed digital I/O, analogue measurement, power control, or something unique, we’ll make sure your system has the right tools for the job.

Tailored Expand Units

Need more? The Agent Expand concept allows you to scale your system with up to four Expand units. These can house additional modules, power supplies, or custom electronics — all integrated seamlessly with the main Agent. It’s a clean, scalable way to grow your test system without growing the mess on your bench.

Tailored Software

Hardware is only half the story. Our software suite is built for flexibility. You can load different software modules in Accordion Pilot, automate test sequences using Python or C#, and integrate with your existing systems via API. Whether you prefer scripting or GUI-based control, the software adapts to your workflow — not the other way around.
