The present disclosure relates methods and apparatus conducting a seismic survey. The apparatus includes an analog interface and power supply both disposed in a housing. The analog interface is configured to receive analog seismic data from a seismic sensor. The apparatus includes one or more of: (i) an isolation transformer disposed between the power supply and the analog interface and (ii) a analog interface clock configured to synchronized with a power supply clock. The method may include reducing power transmission losses and/or the effect of power supply noise on the seismic signals.

Analog in power supply module

The present disclosure relates methods and apparatus conducting a seismic survey while supplying power and data over multiple conductor pairs. In aspects, the disclosure also relates to maintaining power distribution during a failure of at least one conductor pair. The method includes superimposing data and power on each of a plurality of conductor pairs. The apparatus may include a power supply with power supplied by the plurality of conductor pairs carrying power and data.
