ADVANCED GEOPHYSICS INSTRUMENTS MAE advanced geophysics instruments- www.mae-srl.it Seismic / accelerometric digitizer 24 - 96 channels - 24 bit

DESCRIPTION Seismic/accelerometric digitizer equipped with 24-48-72-96 embedded channels for active and passive seismic surveys, dynamic investigations and buildings dynamic studies. X820S basic configuration integrates 24 channels and can be expanded with 24 channels modules, without external boxes, up to maximum 96 integrated channels. Acquisition system represents enhancement of consolidated recording technology AD 24 Bit / S.S.C. (Single Sampler Converter) developed by MAE, which includes adoption of a single analogic/digital converter with high resolution dedicated for each input...

TECHNICAL FEATURES - GENERAL Power supply FUNCTIONING Management application includes many tools which allow to properly set instrument according to operative modalities selected by user, such as: - Data filtering before processing - Data filtering after processing - Gain and signal amplification settings - Sampling frequency setting - Recording time duration - Stacking (iteration) - Sum and difference on each single channel MAE advanced geophysics instruments- www.mae-srl.it

X820S oT Stack operations (iteration) of sum and difference on each channel allow to increase signal / noise ratio, making easier to identify wave phase and specific filtering operations before and after recording. Each channel can be visualized independently and on each trace it is possible to perform frequency analysis (FFT), in order to include main frequencies in real time. It is also possible to program recording geometry on field to facilitate later processing.

X820S In passive seismic mode it is possible to select recording duration and a waiting time before recording start; a progressive bar is visualized, to indicate recording status. Application includes a Tutorial which provides a guide to user for instrument configuration with correct settings for the specific type of survey to perform.
