A Digital Measuring System for Hydrophone Calibration

摘要

A computer-controlled measuring system that combines measurement and computation tasks to speed hydrophone calibration has been developed. The system incorporates one of the popular minicomputers now available. Specifications and developmental problems concerning the related hardware equipment are discussed. The small (4K) core memory size dictated specific approaches to programmed operation. Several modes of operation that meet the initial goals have been provided to make the system as flexible as possible. Programming requirements of these operational modes are reviewed. (Author)
