NRP-1368, NASA REFERENCE PUBLICATION: MARSHALL SPACE FLIGHT CENTER (MSFC) ELECTROMAGNETIC COMPATIBILITY DESIGN AND INTERFERENCE CONTROL (MEDIC) (31 MAY 1995)., (CDDF Final Report, Project No. 93-15) Marshall Space Flight Center Electromagnetic Compatibility Design and Interference Control (MEDIC) Handbook is intended to be used primarily by those organizations involved in the electrical design of payload equipment and subsystems. The purpose of this Handbook is to provide practical and helpful information in the design of electrical equipment for electromagnetic compatibility (EMC). Chapter 1 of this Handbook is an introduction to electromagnetic compatibility (EMC). It includes definitions of terms and units as well as basic electromagnetic interference (EMI) interactions. Chapter 2 is an overview of typical NASA EMI test requirements and associated test setups. It is not intended to be a “how to” of EMI testing, but rather a general overview so that the electrical designer knows what to expect during testing. Chapter 3 contains general design techniques to minimize the risk of EMI and deals with EMI suppression at the board and equipment interface levels. Chapter 4 gives specific EMI test compliance design techniques and retrofit fixes for noncompliant equipment. These techniques and retrofit fixes are specific to a given MSFC EMI test. Chapter 5 explains how to perform special tests useful in the design process or instances of specification noncompliances. Appendix A lists the acronyms and abbreviations used in this document. The MEDIC Handbook was prepared at the Marshall Space Flight Center (MSFC) by the Electromagnetics and Environments Branch (EL54). Funding for developmental testing was provided by the MSFC Center Director’s Discretionary Fund (CDDF), Project No. 93-15.
