Abstract:

The rugged network switch is a ground vehicle equipment used in a certain branches of military.When the electromagnetic compatibility test on the device is performed,the electromagnetic radiation test items (RE102) exceeds the standard range.Equipment analysis identifies the negative factors leading to the electromagnetic leakage in the shell apertures,cable shielding,power protecting and grounding.Corresponding improvement measures are taken to reduce the shell apertures,enhance the cable shielding,improve power shell and change the grounding mode.The improved device passes RE102 test items.
