Alternative Approaches to Radiated Susceptibility Testing at Unit Level: Trade-Off Analysis of Proposed Solutions

Some promising test procedures were recently developed as alternative approaches to radiated susceptibility (RS) verifications for unit-level test setups, with specific (but non-exclusive) reference to aerospace equipment. All test methods are based on the injection of conducted disturbances in the cable under test via suitable coupling devices and fall into two categories: a deterministic and a statistical equivalence scheme. While the former aims at the exact reproduction of RS effects, the latter enforces correlation of outcomes in statistical terms. In this paper, these different approaches are reviewed and critically discussed by the light of merit criteria including cost saving, training, intrusiveness, time consumption, complexity, repeatability and reproducibility, limitations of the equivalence.
