Automatic Test System for an Analog Computer

This paper describes the design, construction, and performance of an automatic test system for the analog portion of a hybrid computation system. The system, which is capable of carrying out complete dynamic testing of each analog component, uses the digital portion of the hybrid system to provide the desired control with the result that the requirement for sophisticated stimulation and measurement equipment is minimized. The hardware and software of the system are both modular in nature in order to provide versatility and to facilitate modifications and additions as required. The design philosophy is such that the methods used are not limited to a particular analog computer. In fact, they have applications in the testing of many types of electronic equipment.
