In modern environmental and durability testing, engineers are under increasing pressure to achieve higher test accuracy, faster system response, and greater testing reliability. As test objects become more sophisticated—ranging from automotive components and aerospace structures to battery systems and electronic devices—traditional vibration control systems often struggle with limited processing capability, unstable real-time response, and complicated multi-channel configurations.

The 9408 Series Vibration Controller is developed to address these challenges through a powerful distributed architecture and advanced real-time control technology. Built on a multi-core ARM and high-speed DSP platform, the system delivers fast computation, stable signal transmission, and highly responsive closed-loop control for demanding vibration testing environments.

Today, the controller is trusted by more than 10,000 users worldwide, supporting applications from standard single-axis tests to advanced multi-axis and multi-degree-of-freedom simulations.
