Vibration Control System MX Series
Vibration Control System MX Series for High-Precision Control
The Vibration Control System MX Series is a network-enabled single-axis vibration control system designed for electrodynamic vibration testing systems. It supports random, sine, and shock vibration control, enabling highly accurate and stable arbitrary waveform reproduction and standards-based testing. Channel configurations can be selected for the application, with support for TEDS and accelerometers with built-in amplifiers.
An export license from Japan’s Ministry of Economy, Trade and Industry is required when exporting vibration controller software overseas. Please contact us for details.
