Abstract: A modular ATE system includes a plurality of test modules and a receiver for use with a variety of fixtures to which printed circuit boards are to be coupled. Each test module includes a plurality of pin cards controlled by a single module controller. Multiple test module are included for testing a variety of functions. Test signals are generated by discrete sets of pin cards and controllers, then output to the receiver for interconnection to a fixture and printed circuit board(s) under test. A substantially wireless receiver is provided, including a translation board for electrically coupling test module pin cards to the fixture. By eliminating wiring and cabling by using a prefabricated translation board, noise is substantially reduced and test signal quality improved. The translation board defines prescribed signal mapping for interconnecting the I/O pins of ATE pin cards to the underside of the fixture. Different translation boards may have different mappings.
