Abstract
A hydrophone preamplifier control unit provides for front panel controls and cable connectors for applying a calibration current and operating voltage to the hydrophone, controlling the level of these voltages, and monitoring the operation of the hydrophone. The control unit assures the continuity of the electrical circuits to a hydrophone through the use of a calibration current applied to the hydrophone through the use of a calibration current applied to the hydrophone through an interconnecting cable.
