Part A. A Data Acquisition/Controller System. Part B. Supplement to a DataAcquisition/Controller System

摘要

A data acquisition/controller system was required to be designed for gatheringdata simultaneously from different radars located spatially apart. Problems encountered in the earlier generation of data acquisition systems were to be alleviated. One of the major problems was the corruption of weak signals by noise on long analog signal cables. Some evidence of video display being another source of noise was also found. Another goal was to reduce the amount of cables going from radar sites to the operator's computer.
