The GSR-12/16, now a legacy product, was an acceleration data acquisition system that represented the state of the art technology in earthquake monitoring. In combination with the high performance e.g. Servo (Force Balance) Accelerometer the GSR-12/16 brought a 72/96 dB dynamic range.
The sensor signals were captured by an A/D converter and digitally filtered to increase accuracy and to provide stable performance. Various parameter settings allowed users to configure the GSR-12/16 very simply and specifically to their desired requirements.
A variety of trigger conditions could be selected to start data capture into a Solid State Memory Bank (SRAM) for later analysis. Recorded data could be conveniently transferred to the central station using the serial interface (PC/RS-232 port or modem).
Transferring data to PC while recording was possible and could be done also via modem. Optionally available was the dial-up system that allowed the GSR to call automatically a predefined telephone number after an event had been recorded.
A comprehensive package of advanced, menu-driven analysis software was available. GeoDAS was included with the GSR-12/16 and could be used on-site for a first impression of the recorded data. GeoDAS Data Analysis Package is a dedicated evaluation program especially designed by GeoSIG for earthquake and civil engineering data analysis. It contains all necessary functions and performances for detailed evaluation in the frequency domain functions (FFT, Power Spectrum, Response Spectrum). Additionally, it included integration (acceleration-velocity and velocity-displacement), CAV (Cumulated Absolute Velocity), Space (Rotation, Display) and various data filters.
The GSR-12/16 was the ideal compact and most cost effective 12 and 16 Bit approach.
