摘要
围绕脉冲和电压这两个通信计量中最基础最重要的计量参数,介绍了万用表和示波器的发展及关键测试技术。认为在数字化、智能化技术变革中,自动多功能校准装置正在逐步取代单一参量的标准装置,计量对象也从对单一仪器和器件的单一参量发展到了对复杂系统的多种参量的综合计量。电子技术日新月异的发展,也不断使通信计量技术测试参量更多、测量范围更广、测量速度更快、测量结果更准确。
In this article, the development of multimeter and oscilloscope and key measuring techniques are introduced around impulse and voltage, the two fundamental but important parameters in communication measurement. In the author＇s opinion, in the process of technological change to digital and intelligent measurement, the automatic multi-function calibration device is taking the place of those for single parameter, and the objects are changing from single parameter of single apparatus/device to comprehensive measurement of multi parameters in complex system. The evolution of electronic technologies have brought about increased parameters, expanded scope, faster speed and more accurate resuits.
