EMI/EMC in Military Systems Including MIL-STD-461/464 & Troubleshooting Addendums

3-Day Course

$1990 per person

Summary

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 course 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.

Thinking about EMC training? The payback is there — just one extra trip to the test lab can cost you $10-20K in test and engineering time! Not to mention the additional cost of being late to market, or the cost of fixing EMI problems in the field.

  • 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)
