Computer-Aided System for Measuring and Recording Short Time Intervals.

摘要

An inexpensive computer-aided system has been developed for the measurement and storage of short time interval data. The use of interchangeable time base oscillators, an open-ended, modular counting architecture, signal processing of user-supplied handshaking signals and regulation of power supply voltage allow system to be adapted to a wide variety of applications. Construction and assembly of this system is simplified by the use of commercially available PC digital interface boards. Schematic diagrams, complete descriptions of circuit functions, and sample software are included.
