Geophysical data acquisition system
First Claim
1. A geophysical data acquisition system, comprising:
- at least one geophysical sensor, the at least one geophysical sensor having associated therewith a signal generator configured to generate a signal corresponding to a type of the at least one geophysical sensor; and
at least one signal acquisition unit having a plurality of input channels, the at least one geophysical sensor in signal communication with one of the plurality of input channels, the plurality of input channels each including a central processor for receiving the signal generated by the signal generator and identifying the type of sensor associated with the received signal, the at least one signal acquisition unit including amplification, filtering and digitizing circuits automatically configurable in response to the type of sensor identified by the detected signal.

Abstract
A geophysical data acquisition system includes at least one geophysical sensor. The at least one geophysical sensor has associated therewith a signal generator configured to generate a signal corresponding to a type of the at least one geophysical sensor. The system includes at least one signal acquisition unit having a plurality of input channels. The at least one geophysical sensor is in signal communication with one of the plurality of input channels. The plurality of input channels each includes a detector for receiving and identifying the signal generated by the signal generator. The at least one signal acquisition unit includes amplification, filtering and digitizing circuits automatically configurable in response to the type of sensor identified by the detected signal.
