技术的发展已允许生产许多新的电子测量仪器来满足对更高准确度和精密度不断增长的要求。近来,随此趋势,已生产出许多与传统仪器相当的数字化设备。其中的一些只是其模拟式原型的更精确的数字式改进型,而另一些则又提供了用模拟技术不能得到的特性。标准的实验室示波器是现有的最通用的单个仪器。近来已经有了数字示波器,正是这些模拟示波器的数字式改进型,作为其数字设计的结果仅仅提供少数操作上的方便。其中一些仪器和小型计算机结合使测量过程得到完全新的途径。然而,这种系统有一些主要的缺点,包括价格高,用户必须编制计算机程序,以及还没有构成一个紧凑的仪器等等。微处理器的发展使得可以用数字技术来设计新类型的通用实验室仪器。体积小、成本低的微型计算机使得制成的仪器是微型计算机使得制成的仪器是紧凑的,因而以合理的价格给 Technological advances have allowed the production of many new electronic measuring instruments to meet the ever-increasing demands for greater accuracy and precision. Recently, with this trend, many digital devices have been produced that are comparable to conventional instruments. Some of them are more precise digital improvements of their analog prototypes, while others provide features not available with analog technology. The standard laboratory oscilloscope is the most versatile single instrument available. Recently there have been digital oscilloscopes, which are digital improvements of these analog oscilloscopes that, as a result of their digital design, offer only a handful of operational conveniences. Some of these instruments and small computers combine to make the measurement process completely new. However, there are some major drawbacks with such a system, including the high price, the user having to prepare a computer program, the lack of a compact instrument, and so forth. The advent of microprocessors has made it possible to design new types of universal laboratory instruments using digital technology. The small size and low cost of the microcomputers make the resulting device a microcomputer that makes the resulting instrument compact and therefore at a reasonable price
