Twelve more real-world EMC failures across emissions and immunity. Pick any card to see its spectrum/symptom signature, how it was localized, the fix that worked, and the resulting margin. Each one exercises the six-step loop from Module 10.

How to use this library. These are teaching cases with illustrative
numbers. For each, try to predict the fix from the signature before reading
it — that's the skill this course builds. E =
emissions, I = immunity.
Notice the recurring themes: cables are the usual radiator; the fix is almost always at the source or the common-mode current, not a shield; and the same coupling paths cause both emissions and immunity problems. If you internalize those three, most failures collapse to a handful of fixes.
Course complete. You now have a mental library of signatures and
their cures. Combined with the bench, technique and methodology from Modules 1–10,
you can walk into an accredited lab expecting to pass — the goal of the whole
EMC track.
