Accordion

The Accordion test system is a modular hardware platform for electronics production test, design verification, and NPI — built around a single test node, a library of plug-in modules, and a consistent control API across Python, .NET, TestStand, LabVIEW, and REST.

Browse the full Accordion catalog here, or jump to a specific family: A2 instruments, individual modules grouped by function, Accordion software, and Accordion Expand for distributed test setups. Every product follows the same channel model, so test code written for one Accordion node runs unchanged on another.
