<p>Circuit for localising an error on a printed card, which is arranged to operate in conjunction with a computer loaded with a functional test programme to seek out incorrect functions carried out by the computer. The device (2) contains two sockets (3, 4) of a particular type. Used for engaging the printed card. The coupling circuits (5, 6, 9, 10) are parallel to the sockets. There is also a reference printed board which is used for comparing the signals. This is done by comparing the signals appearing at the sockets when the cards are inserted. The signal comparator circuit (7) is connected to the sockets via cable loom (11, 12).</p> |
