DYNAMIC TIME-DOMAIN REFLECTOMETRY ANALYSIS FOR FIELD REPLACEABLE UNIT ISOLATION IN A RUNNING SYSTEM

Abstract:

A technique relates to dynamic time-domain reflectometry (TDR). A machine spares a bad lane in a bus. The bad lane is taken offline. TDR is dynamically executed on the bad lane while the bus is still in operation. A defect is isolated using results of the TDR.
