信号完整性是指电路系统中信号的质量,如果在要求的时间内,信号能够不失真的从源端传送到接收端,那么该信号是完整的。由于系统时钟频率的增长,信号完整性测试变得越来越重要。本篇介绍了电子产品生产过程中高速电路信号完整性波形测试的基本方法和原理分析。 Signal integrity refers to the quality of the signal in the circuit system, which is complete if the signal can be transmitted from the source to the receiver without distortion within the required time. As the system clock frequency increases, signal integrity testing becomes more and more important. This article introduces the basic method and principle analysis of high-speed circuit signal integrity waveform testing in the electronic product manufacturing process.
