Hi, experts I am troubleshooting an interconnect issue. The symptom is intermittent open when mechanical force is applied (hit by a stick etc.). TDR is a good tool to pin point the exact location of open. But this intermittent issue only last for micro seconds. TDR today has continuous trigger. It can't catch the single event. Does any one know how to trigger TDR with single event? Or any other tools to pin point the physical location of intermittent open? Thanks!
