ABSTRACT:
A test fixture is provided for testing electrical characteristics associated with a printed circuit board (PCB). Spaced-apart solenoids each have an extendible arm aligned along an axis defined by a connector assembly on the PCB to be tested. The arms are located to have sufficient travel to engage the side of the connector assembly. A mechanism is provided which detects which of the arms engage the connector assembly. Arm engagement data is stored in memory of a PC for type of connector assembly to be tested by the apparatus. A mechanism is provided for determining if a correct test program has been selected by a user for testing a particular connector assembly based on whether the arm engagement data matches the arms that engage the connector assembly.
