An Interface Test Adapter (ITA) is used to connect the specified Unit Under Test (UUT) to the Intermittent Fault Detection & Isolation System (IFDIS). Each ITA is individual to the specifications required to adapt to the unit to be tested. Each ITA simulates the form and fit of all UTT connections (Cards, Front Connectors & Rear Connectors) both internally and externally.
The component parts of a Line Replaceable Unit (LRU) ITA are as follows: Virginia Panel Connector(s), 24 gage wire in cables of 100 wire each (as many as required to make all connections), circular front facing connectors, rear facing connector(s), replicas of each circuit card installed in the LRU to interface with the LRU Backplane and a Fixture used to mount the UUT within the environmental chamber.
The cost of an ITA is a function of it's complexity, including Cards required to be installed in place of the active CCAs, assembly time, quality verification of individual parts and the completed assembly, and testing (static & dynamic).
