我们常把发动机比作汽车的心脏,示波器可以通过波形直观地显示出发动机技术数据、工作状况、故障所在,因此把示波器比作汽车的心电图是再恰当不过的了。 本刊自2001年6月号连载“示波器的使用与波形分析”系列讲座以来,在广大读者中引起很大反响。那些已经购置了示波器的读者感叹道:没想到示波器有这么多的用途:那些没有示波器的读者更是跃跃欲试。由于讲座中使用的是一款市面上很少见的日本示波器,因此,许多读者向我刊询问诸如:国内市场上有哪些可选购的示波器?各种示波器有哪些技术特点?如何在实际维修中更好地使用示波器等问题。针对这些问题,我们采访了有关专家。据专家们介绍,目前市面上已经很少有单纯的汽车专用示波器,示波器正在被容纳入综合汽车检测仪器之中。我们组织了一些汽车维修专家根据对比使用的结果,选择了两款性能卓越、适用广泛的示波器(含有示波器功能的综合检测仪器)推荐给读者。
We often compare the engine to the heart of a car. The oscilloscope can show the engine technical data, working condition and fault intuitively through the waveform. Therefore, it is more appropriate to compare the oscilloscope to the car’s electrocardiogram. Since the serial issue of “Oscilloscope Usage and Waveform Analysis” series published in June 2001, this magazine has aroused great repercussions among the readers. Those who have purchased an oscilloscope exclaim: There was so much use for oscilloscopes that those who did not have an oscilloscope were even more eager. As the lecture is using a rare Japanese oscilloscope on the market, many readers asked me questions such as: What are the optional oscilloscopes on the domestic market? What are the technical features of various oscilloscopes? In the better use of oscilloscopes and other issues. In response to these questions, we interviewed the experts. According to experts, there are very few automotive-specific oscilloscopes available on the market today, and oscilloscopes are being incorporated into comprehensive automotive testing instruments. We organized a number of automotive maintenance experts based on the results of the use of contrast, chose two high-performance, widely used oscilloscope (with integrated oscilloscope detection equipment) recommended to the reader.
