The Spider-81 is a 4th generation vibration control system developed by Crystal Instruments. It is the first controller that directly integrates the time-synchronized Ethernet connectivity with embedded DSP technology, greatly increasing the control performance, system reliability, and failure protection.
Dual, parallel 24-bit A/Ds provide 130 dB of dynamic range for even low level tests and a modular design allows expansion up to 64 input channels. Tests can be executed in Black Box mode, which allows it to operate without a PC. A complete suite of vibration tests are available including, Sine, Random, SoR, RoR, RSTD, TTH, TDR, Shock and more. Also available is a full suite of general signal analysis functions.
