The SMAD digitizer is a data acquisition system specially dedicated to analog or digital geophysical sensor recordind.
It allows the acquistion of 4 analog channels with an électronic noise below 1 µV/VHz and a dynamic range up to 130 dB @ 50 Hz.
Auxiliaries’ input allows 16 bits low frequency signals recording like meteorological sensors or vault temperature.
The instrument has two RS-232 and one Ethernet User interface remote control.
SMAD is a product developped under CEA (commissariat à l’énergie Atomique) contract.
