Alpine Announces Digital Depth Tracker A new digital depth tracker, which automatical-ly tracks depths down to 6,000 fathoms with 0.1 fathom resolution, has been announced by Alpine Geophysical Associates Inc. Designed to operate with most sonar transceivers, the tracker determ-ines depth by measuring the time interval between transmission of the acoustic pulse and receipt of the echo. A fast slew feature permits an operator to po-sition an internally generated gate to acquire the echo. Once acquired, the gate automatically tracks the echo. Each valid echo causes depth to be pre-sented on a 5-digit nixie display and to be avail-able at a 1-2-4-8 BCD output for use by external data processors, recorders, etc. Front-panel controls permit selection of gate width and receive sensitivity from 50 mvrms to 5 vrms. Audible and visual alarms indicate bad data if no echo is received, or if echo is received out-of-gate. A built-in self-test feature rapidly checks out most circuitry by simply flipping a switch. The tracker can be bench operated in its cabinet or mounted in a standard 19-inch rack. It is com-pletely self-contained, having its own d-c power supplies, and requires 115 volts ?10 percent, 60 Hz ± 5 percent, 50 watts, single-phase power. It weighs 50 pounds.
