Great article! Going to forward it to my manager (non EE) who I keep denying requests for MILSTD-461 testing. The switching supplies ICs (with integrated FETs; like from Linear Tech, TI, etc) are noisy where you might not think. Extremely fast rise times on the FET generates white noise through 2 GHz, even if it's only running at a few 100 kHz. Putting wrong bypassing/filtering parts on can only make it worse as they will act like an antenna. It may not even show up in a EMC test but enough to degrade RF receiver sensitivity a few dB.
