When engineering fixes meet business pressures, technical integrity is put to the test. This article reveals how a simple cable break dramatically degraded EMC performance by up to 40dB, yet management chose the convenient answer over empirical evidence—a cautionary tale for compliance engineers everywhere.
Control of low audio frequency magnetic fields from cables, as required by some spacecraft EMI control standards, is best implemented as a conducted emission measurement, but these may require exceptionally efficient transducers and techniques, which are discussed herein.
This third and final part looks at Section 6 (Interference Potential of EDP/OE), Section 7 (The Commercial EDP/OE Interference Models), Section 8 (Emanation Limits for EDP/OE Products), Section 9 (Comparisons of Recommended Limits with Others), Section 10 (Emanation Measurement), and Section 11 (Conclusions).
