电子示波器是常见的一种电子测量仪器,它能把肉眼无法直接看到的电信号转换成可直接观测的波形,为人们检修某些家用电器的电路故障提供了方便,特别是利用它来检修电视中的某些电路故障,可以直观、准确地查出故障原因,极大地缩短了检修时间。电子示波器种类较多,但就检修电视机来讲,对示波器的要求并不严格,像SR—8型双踪示波器就足可以满足检测要求,电视机在出厂时都附有一张电路原理图,上面标有许多关键部位的信号波形和幅度,利用示波
Electronic oscilloscope is a common kind of electronic measuring instruments, it can directly see the naked eye can be converted into electrical signals can directly observe the waveform, for some people to repair the electrical circuit failure, providing convenience, especially the use of it to overhaul Some of the TV circuit failure, you can intuitively and accurately identify the cause of the malfunction, greatly reducing the maintenance time. There are many types of electronic oscilloscopes, but in terms of overhauling the TV sets, the requirements on the oscilloscopes are not strict. For example, SR-8 dual trace oscilloscopes can meet the testing requirements. The TV sets are shipped with a circuit schematic, The signal waveform and amplitude of many key parts are marked with the oscilloscope
