Vibration control and analysis system
130 dB | Spider-81 VCS Crystal Instruments

Spider-81 is a highly modular, distributed, scalable vibration control system developed by Crystal Instruments. It represents the fourth generation of vibration control systems because its advanced technology is not seen in any other products. It includes a complete suite of vibration control modules including Sine, Random, Sine-on-Random, Random-on-Random, Classical Shock, SRS, Time Data Replication, and Dynamic Signal Analyzer functions.
DSP Centralized Architecture
Unlike traditional controllers that rely heavily on an external computer for real-time operation, Spider is the first controller that directly integrates timesynchronized Ethernet connectivity with embedded DSP technology. This strategy greatly increases the control performance, system reliability, and failure protection of the controller. It also allows large numbers of channels to be configured without sacrificing system performance.
