The SMAD digitizer is a data acquisition device specially dedicated to analog or digital geophysical sensor recording. It allows the acquisition up to 4 channels with an electronic noise below 1 μV/√Hz and a dynamic range up to 130 dB @ 50 Hz. The PPS board, thanks to a temperature correction table, allows very small drifts of time tagging even if the GPS is not available. A calibration board is embedded for on site or remote sensor calibration such as sine, impulse or MLS (up to order 15) signals. Auxiliaries’ input allows 16 bit low frequency signals recording like meteorological sensors or vault temperature. Communication with the equipment is addressed through an Ethernet link or RS232 and CD1.1 data format is available.
