Laboratory Exercises to Accompany Chapters 10-12
These demonstrations and laboratory exercises illustrate concepts described in Electromagnetic Compatibility Course Notes.
Chapter 10: Low-frequency Magnetic-field Shielding
At low frequencies, magnetic field shielding materials redirect the field using magnetic materials.
Laboratory Exercise 23: Low-frequency Magnetic-field Shielding
Chapter 10: High-frequency Magnetic-field Shielding
At high frequencies, magnetic fields can be redirected by the eddy currents in conductive materials.
Laboratory Exercise 24: High-frequency Magnetic-field Shielding
Chapter 10: Electric-field Shielding
Conductive materials can stop electric fields at virtually any frequency. Unlike magnetic-field shields, how and where an electric-field shield is grounded can be very important.
Laboratory Exercise 25: Electric-field Shielding
Chapter 11: Visual Inspection of Circuit Boards
What can you say about a board's chances of meeting its EMC requirements just by looking at it?
Laboratory Exercise 26: Visual Inspection of Circuit Boards
Chapter 11: Pre-compliance Emissions Measurements
What can we learn about sources of radiated emissions based on near-field measurements?
Laboratory Exercise 27: Pre-compliance Emissions Measurements
Chapter 12: Visual Inspection of Commercial Products
What can you say about a product's chances of meeting its EMC requirements just by looking at it?
