A testing device generates electromagnetic noise such as transients, power interruptions and Radio Frequency Interference (RFI) for application to an electronic device to test the immunity of the electronic device to electromagnetic noise or to test the performance of the electronic device during exposure to electromagnetic noise. The testing device promotes an economical and efficient evaluation of Electromagnetic Compatibility (EMC) of an electronic device during product design or otherwise. The testing device includes a switch having electrical contacts for producing electromagnetic noise during a transition between a closed state and an open state of the electrical contacts and a trigger that is coupled to the switch. The trigger is arranged to change states between the closed state and the open state of the electrical contact. An input terminal is associated with the switch for applying electrical energy to the switch. An output terminal is associated with the switch for connection to the electronic device for testing operation of the electronic device in response to the electromagnetic noise.

Testing device for evaluating the immunity of an electronic device to electromagnetic noise

An electronic module includes a Printed Circuit Board (PCB) which contains a plurality of circuit elements. The electronic module is electrically connected to other electrical components in a vehicle by a connector. The PCB is contained within an electrically conductive housing which includes a box and a cover. A ground trace printed on the PCB extends to a mounting hole in the PCB and provides a ground path for the circuit elements. An electrically conductive metal ferrule which elevates the PCB above the box and the cover above the PCB, extends through the mounting hole in the PCB and contacts the cover and box when the cover is fitted onto the box. A mounting bolt extends through the cover inside the ferrule through the box and into a nut mounted into a metal portion of the vehicle.
