Abstract: A test bracket includes a base board and two position poles. The position poles are perpendicularly and slidably mounted on the base board opposing each other. Each position pole defines a groove opposing the other position pole. A distance between the position poles is adjusted through sliding the position poles on the base board along the slots. The position poles hold a circuit board to be perpendicularly mounted on the base board by receiving the circuit board in the grooves.

Abstract: An exemplary video graphics array interface tester includes a VGA connector being configured to couple to a VGA interface to be tested and having a plurality of signal pins to output different VGA signals; a load circuit connected to the signal pins of the VGA connector for impedance matching; a selection switch having a plurality of throws corresponding to the signal pins of the VGA connector connected to the signal pins of the VGA connector respectively, and a pole; and a test port connected to the pole of the selection switch for selectively testing one of the VGA signals via selection of the selection switch. Using this tester to detect the VGA interface can guarantee quality and improve efficiency of VGA test.
