在今天的电子设备中,电子仪器更是千变万化难以预计,所以就难怪有人会认为,示波器将失去它在电子工业中作为主要测试工具的地位。他们指出大规模集成电路产量急剧增长,价格越来越便宜,因此有时更换一块有故障的电路板,要比检修这块电路板的故障上算得多。他们说,用一般示波器来分析数字电路故障太麻烦了。有些人总是认为,示波器在测量参数与测量多用性方面已达到了它的极限。虽然我们同意他们这些论点所依据的许多前提,但是并不同意他们的某些结论。今天的示波器最高频率为500MHz,而明天的第一流示波器将具有良好的灵敏度和千兆
In today’s electronic devices, electronic devices are ever-changing unpredictable, so no wonder some people think the oscilloscope will lose its status as the main test tool in the electronics industry. They pointed out that the output of mass integrated circuits (ICs) has risen sharply and at an ever-cheaper price, so it is sometimes more difficult to replace a faulty circuit board than to repair the circuit board. They say it is too cumbersome to analyze a digital circuit with a typical oscilloscope. Some people always think that oscilloscopes have reached their limits in terms of measuring parameters and measuring versatility. While we agree with many of the premises on which these arguments are based, we do not agree with some of their conclusions. Today’s oscilloscopes have a maximum frequency of 500MHz, and tomorrow’s first-class oscilloscopes will have good sensitivity and gigabit
