Abstract

This paper discusses typical electromagnetic interference (EMI) problems encountered in airborne/ground subsystems during EMI/EMC performance evaluation for conducted emission, radiated emission and conducted susceptibility tests. It also highlights different suppression techniques, followed in hardening the units by selecting proper EMI power line filters, using appropriate shielding aids, good grounding practices and transient protection devices to achieve electromagnetic compatibility (EMC) in all the equipment to meet the test requirements. Finally the test results along with the specification limits are also given.
