微处理机(μp)和微型计算机(μc)近年来获得了迅猛发展,应用领域不断扩大.其中一个重要的领域是数字仪表。目前生产的数字仪表内部都装有一部或多部μp/μc.它们大有取代传统的模似仪表的趋势。数字仪表发展如此迅速的驱动力则是它的高精度,高速度,高稳定性,使用方便,应用广泛同时也因为各种各样的通用数字仪表可以很快的组成为实现各种不同目的,任务、要求的自动测试系统ATS(Automatic Test System).
Microprocessors (μp) and microcomputers (μc) have enjoyed rapid growth in recent years, and their applications are expanding. One of the most important areas is digital instrumentation. The current production of digital instruments are equipped with one or more internal μp / μc. They have greatly replaced the traditional analog meter trend. The driving force behind the rapid development of digital instruments is its high precision, high speed, high stability, easy to use, widely used and also because of a variety of general-purpose digital instruments can be quickly formed for a variety of purposes, Tasks, Requirements Automatic Test System ATS (Automatic Test System).
