通常我们检测远动信号使用示波器,可以直观地了解信号的幅度、波形等特性.但有时在检修时手头没有示波器或只需判断运动信号传输是否中断,对于这些情况,笔者在实际工作中常用以下两种测试方法:方法一 用一只8Ω、0.25W的喇叭(普通收音机喇叭即可),引出两根线.检
Usually we detect the use of telemetry oscilloscope, you can intuitively understand the signal amplitude, waveform and other characteristics.However, sometimes in the repair without the oscilloscope on hand or just to determine whether the movement of signal transmission is interrupted, for these cases, I often used in the actual work below Two test methods: Method One with a 8Ω, 0.25W speakers (ordinary radio speakers can be), leads to two lines.
