Printed circuit board test system and application thereof to testing printed circuit boards forming a digital signal multiplex- demultiplex equipment

摘要

A printed circuit board test system includes a test printed circuit board adapted to be connected to a printed circuit board to be tested. At least one of these two boards is equipped with circuits for selecting the types of signal processed by the board to be tested, adapted to place at least one subsystem of the latter either in a test configuration or in a normal configuration. The test board is provided with configuration control ports and equipped with circuits for connecting these ports to the selector circuits.
