Abstract
Abstract A data recorder for recording and simultaneously printing both analog and gital data on the same strip chart. The simultaneous recording of both the analog and digital data provides a permanent time base correlation of the event(s) represented thereby which is extremely useful for instant analysis of later study. In a preferred embodiment, two channels of analog information are recorded by pen styli and are representative of the output of a pair of condensation nuclei counters for monitoring atmospheric pollution. The digital data is recorded simultaneously adjacent the analog information in its own channel and represents position coordinates corresponding to the location of the airborne counters at any given point in time and may, for example, comprise the digital output of a LORAN-C navigator. The simultaneous output allows immediate correlation between the maxima and minima of the analog traces and position.
