Test device for printed circuit cards and its application for testing printed circuit boards, forming a multiplexer-demultiplexer arrangement for numerical signals

摘要

This test device for a printed circuit board includes a printed circuit board, termed a test card, capable of being connected to the printed circuit board to be tested. At least one of these two boards is equipped with circuits for selecting the type of signals processed by the board to be tested. These circuits are capable of putting the board to be tested either in the test configuration or in the normal configuration. The test card is fitted with configuration control ports and is equipped with circuits for connecting these ports to the said selection circuits. …IMAGE…
