示波器探头在测量中的重要性

Importance of Oscillograph′s Probe in Measurement

示波器一直是工程师设计调试产品的好帮手。随着计算机、半导体和通信技术的发展,电路系统的信号时钟速度越来越快,信号上升时间也越来越短,导致因底层模拟信号完整性问题引发的数字错误日益突出。要想准确快速地对系统信号进行分析,测量时还有很多新的因素必须考虑。如仪器速度能否跟上被测信号的变化,带宽是否足够,测量方法会不会引入干扰,甚至还有所使用的探头是否合适等等。

Oscillograph is a helpful assistant for engineers in product designing and debugging. With the development in computer, semiconductor and communication technology, the signal clock in a circuit system works faster and the signal rise time gets shorter, therefore ,the integrality of substrate analog signals brings about more and more eminent digital errors. In quick and accurate analysis of the system signal ,many new factors as the following must be taken into accounts in measurement. The apparatus operating speed as fast as the surveyed signal changing ,bandwidth wide enough,possible interfering factors inmeasurement ,asuitable probe ,and so on.
