An analogue recording system for recording pulse series
Abstract
An analogue recording system for the visual display of pulse series intermittently received from oceanographic sensors is described. It is composed of a mechanically-modified pen recorder and a newly designed electronic driving unit, and it includes arrangements for (1) regulating the speed of the pulse- marking device by means of a stable reference frequency; (2) starting each pulse series on command; and (3) expanding the measuring scale. These requirements could not be found in commercially available recorders, necessitating the development of the one described. The system can be used either for simultaneous recording, being suitable for use on board ship, or for play-back recording from magnetic tape.
