Intermittent Fault Detection & Isolation System
IFDIS
-
The IFDIS™ uses patented Intermittent Fault Detector technology that simultaneously and continuously monitors every circuit path within a Unit Under Test (UUT) - such as a Line Replaceable Unit (LRU) chassis' interconnects - for intermittent continuity failures that occur for as short as 50 nanoseconds. This state of the art technology is combined with an environmental chamber and vibration table, which simulate the UUT’s operational environment and cause intermittent faults to manifest, creating a system that is unsurpassed in intermittent fault detection.
