用传统的检测工具(如示波器、逻辑分析仪等)进行维修时,维修人员往往是从电路板的功能出发逐级检测,这通常需具备两个前提:一是对故障电路板的工作原理比较清楚;二是对被测板能够测试到稳定的信号。而在实际工作中,这两个前提一般很难同时得到满足,因而给维修工作造成了很大的难度。若使用正达电路维修测试仪进行电路故障检测,上 When using traditional detection tools (such as oscilloscopes, logic analyzers, etc.) for maintenance, maintenance personnel often conduct step-by-step tests based on the functions of the circuit board. This usually requires two preconditions: First, the working principle of the faulty circuit board is compared Clear; Second, the board can be tested to a stable signal. In actual work, these two premises are generally difficult to meet at the same time, thus causing great difficulty to the maintenance work. If you are using the circuit repair tester for circuit fault detection, on
