In automated test equipment for testing circuits located on a card, the signature analysis technique has proved useful. This discloses a special interface card, termed a personality card, for interfacing between the automated test device and the card under test, enabling the card under test to exercise itself (where the card under test contains a microprocessor) or enabling a microprocessor to be placed on the personality card so that the combination of the personality card and the card under test can exercise itself.
