对于电子仪器的维修,如果只停留在起子、钳子、烙铁、万用表、示波器等简单的工具和仪表,往往只能解决一般性的问题,对于仪器内部较复杂的故障,就得用先进的仪器来诊断。由于大规模集成电路和各种数字电路以及微处理机在电子仪器上的应用,因此在各线路板上的输入和输出中,各点的波形、波形时延和夹断脉冲,以及各组总线的输出语句与地址码等,用一般仪器是难于获得准确信息的,特别是同一个时间的几个 For the maintenance of electronic equipment, if only stay in the screwdriver, pliers, iron, multimeter, oscilloscope and other simple tools and instruments, often can only solve the general problems, for more complex equipment failure, you have to use advanced equipment to diagnosis. Due to the application of LSIs and various digital circuits and microprocessors in electronic instruments, the waveform of each point, the waveform delay and pinch-off pulses, and the resistance of each group of buses The output of the statement and address code, with the general equipment is difficult to obtain accurate information, especially at the same time a few
