EMI/EMC in Military Systems Training Course Description

EMI/EMC in Military Systems Training, Systems EMC (Electromagnetic Compatibility) involves the control of EMI (Electromagnetic Interference) at the systems, facility, and platform levels (e.g. outside the box.) This three-day EMI/EMC in Military Systems Training provides a comprehensive treatment of EMI/EMC problems in military systems. These include both the box level requirements of MIL-STD-461 and the systems level requirements of MIL-STD-464.

The emphasis is on prevention through good EMI/EMC design techniques – grounding, shielding, cable management, and power interface design. Troubleshooting techniques are also addressed in an addendum. Please note – this class does NOT address circuit boards or specific test issues. Each student will receive a copy of the EDN Magazine Designer’s Guide to EMC by Daryl Gerke and William Kimmel, along with a complete set of lecture notes.

Certified Secure Software Lifecycle Professional Training (CSSLP) – Customize It:

• If you are familiar with some aspects of this EMI/EMC in Military Systems Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the EMI/EMC in Military Systems Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the EMI/EMC in Military Systems Training course in manner understandable to lay audiences.

EMI/EMC in Military Systems Training – Skills Gained:

• How to identify, prevent, and fix common EMI/EMC problems in military systems
• Simple models and “rules of thumb” and to help you arrive at quick design decisions (NO heavy math).
• EMI/EMC troubleshooting tips and techniques.
• Design impact (by requirement) of military EMC specifications (MIL-STD-461 and MIL-STD-464)
• EMI/EMC documentation requirements (Control Plans, Test Plans, and Test Reports)
