现代的科学实验和工业试验,不仅要求所使用的测量仪器有很高的精度,同时希望能将测量结果及时按照相当复杂的计算公式进行处理,有时甚至要求同时采用几种仪器相互配合使用.为此,计算机被引入了测试系统,产生了能与计算机配合自动完成一系列测量和计算任务的智能测试仪器.为了实现计算机与 Modern scientific experiments and industrial experiments require not only the high accuracy of the measuring instruments used but also the timely processing of the measurement results according to rather complicated calculation formulas and sometimes the simultaneous use of several instruments at the same time. As a result, computers were introduced into the test system, creating intelligent test instruments that can be used with computers to automate a range of measurement and calculation tasks.
