【摘要】 示波器是一种既操作简单又常见的测量仪器,是电子行业不可缺少的重要测试工具之一。在缺乏专用仪器测试一些终端产品的接口性能的特殊情况下,用示波器来代替专用仪器进行测试仍然是一种方便实用的办法。介绍了用示波器来测试三种常用接口性能的简要方法,其中着重讨论了用示波器测试音频放大电路的基本思路,这些方法为电子产品接口性能测试提供了另一简洁途径,对其它性能测试也具有指导意义。更多还原

【Abstract】 The oscillograph is a kind of simple and common testing apparatus, It is one of indispensable tools in the electronic field. In case of testing performace of product interfaces without special apparatus, the oscillograph can be used instead of the special apparatus and it still be a convenient applied way. It describes several ways to test three kinds of interfaces with the oscillograph, and it emphasized on the basic method of testing audio-magnified circuit, and provides another simple way to test performance of electronic product interfaces, meanwhile, it also gives an instructional means to other performance tests.更多还原
