The GSR-18 Strong Motion Recorder, now a legacy product, had a dynamic range of 111 dB @ 100 SPS and 108 dB @ 200 SPS. The standard 3 channel system had selectable sampling rates from 100 to 250 SPS.
A variety of sensors could be connected to the GSR-18 offering solutions for applications in miscellaneous fields.
Various network solutions such as independent or interconnected recording networks and local or central recording networks could be configured easily with highly advanced functions such as online surveillance, common trigger and time synchronisation. The standard parameter settings and the user-defined configurations could be transferred easily from the PC to the GSR-18.
Transferring data to PC while recording was possible and could be done also via modem. Optionally available was the dial-up system which allowed the GSR-18 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-18 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-18 was also available as GSD-18 Digitiser only integrated into GeoSIG Seismic Network Systems.
The GSR-18 was the ideal, compact and most cost effective 18-Bit approach.
