Hardware-in-the-Loop (HIL) Testing

The National Instruments hardware-in-the-loop test platform utilizes open hardware and software technologies to reduce the time, cost, and risk associated with control system development. These solutions scale from low-cost PC-based testers to high-performance multicontrollers and can improve system integration of test applications as well as provide test solutions from requirements definition to manufacturing test.
