Wide band
magnetotelluric station LEMI-419
is intended for the study of natural electromagnetic fluctuations in the
frequency band 0.0001-200
Hz in field conditions. The station maintains automatically measurements in
wide temperature range and digitizing data from 3 search-coil magnetometers,
4 telluric channels and monitors the temperatures of sensor and electronics.
The real time acquisition, recording and visualization of current and
previously recorded data are executed at an external computer to which
digital data are transferred through serial RS-422 port. The station
operation is synchronized with GPS timing.
