A vibration controller feature used within a closed-loop test system to produce a random signal that simulates a broad range of real-world operating environments.
he random vibration (or excitation) test profile simultaneously excites all resonant frequencies of any given payload, thus it is well suited for product qualification tests and for characterizing a structure’s dynamics. A fast loop time is important for high accuracy, and so are multi-channel control, notching, and real-time analysis.
