摘要
介绍了TDR(Time Domain Reflectometry)时域反射计的原理。提出了基于传输线理论建立的时域反射计的模型。研究了该模型在各种阻抗非连续性下的工作状态。采用高速采样模块,高性能示波器和TDR发生模块组成Tektronics-CSA8200的TDR测试系统,将TDR技术应用于大规模集成电路的失效分析,快速准确的定位故障,解决了复杂集成电路封装造成的故障诊断的困难,并给出具体应用实例。
Introduced TDR(time domain reflectometry)theory.Established the module of TDR based on transmission line theory.Researched the statures of TDR module which worked at discontinuities failure.TDR measure system included high speed AD module,high performance oscilloscope and TDR module.Applied TDR technology in integrate circuit failure analysis,it was fast and precise to focus on failure,and solve the problems of complex packages of integrate circuit failure analysis.There was a real case of TDR application i...
