ABSTRACT:
A test fixture (14) for coupling a circuit board (12) to an automatic testing machine (13) includes a translator board for coupling each of a plurality of test pads (26) on the board to a separate one of a plurality connecting members (22) arranged in spaced-apart rows. Each row of connecting members is coupled via a paddle card (36) and a channel card (44) to a separate channel of the testing machine (13). In accordance with the invention, a paddle card (36') containing circuitry (52') for signal logic level translation may be substituted for one of the paddle cards (36) when it is necessary to translate the logic level of certain signals passing between the testing machine (13) and the circuit board (12).
