ITA or ITEA a comprehensive dissimilarity

Although it is assumed an Interface Test Adapter (ITA) is an Interface Test Adapter; this is not necessarily true. The whole concept of an Interface Test Adapter is to route Automatic Test Equipment (ATE) signals from the ATE to the Unit Under Test (UUT) and signals from the UUT to the ATE. Also, the ITA has the UUT connector and card guides (when testing circuit cards) so the UUT can be connected to the test equipment. However, there can profound differences between ITAs and ITA concepts. The profound difference between ITAs is the use of active components. Adding active components, over and above the standard noise reducing capacitors or load resistors (passive components), essentially makes the ITA part of the test equipment itself.
