EMI controlling in a rugged launch computer

Developing of a rugged launch mobile computer system in rack mountable form is not an easy task. If the system is going to be used in a stringent EMI environment, then achieving the EMC is a challenging task for the designers and EMI engineers. Initially the system did not qualify to met all the EMC requirements even after implementing the possible EMC measures in the design and development Achieving EMC by design is must. The EMC engineers analyzed the design concept of the system and its failures during EMI/EMC performance evaluation. In this paper the authors mainly highlighted and expressed their views about the incorporation of EMC measures, fixes and final achievement in qualifying the system. The authors also explained the electromagnetic compatibility achievement. The sequence adapted in achieving EMC is explained.
