Design and Operation of Four Equipment Interfaces for Recording Data onto Serial Printers.

摘要

Descriptions are given of the design and operation of interface equipment which receives digital data from precision commercial measurement instruments,processes the data,and upon command,outputs it to an ASR-33teletype. The measuring instruments are a digital teraohmmeter from Guildline and a digital voltmeter, a Wheatstone bridge,and a universal ratio set,all from Leeds and Northrup. The interfaces were designed to permit automatic recording of data onto paper and punched paper tape in a format compatible with the CDC 6600computer.
