Measurement and Modeling of SpaceWire Radiation for Electromagnetic Compatibility Assessment

In the present work, authors present measurements of the radiated emissions for different data rates of Space Wire signaling and various payloads. The test campaign is based on the military-standard and a novel approach to assemble a model appropriate for electromagnetic compatibility assessment is proposed. Authors improve upon a previous work the modeling approach including all identified skew effects of the link. These effects are the main sources of common-mode currents which are the key mechanism for the radiated emissions of the harnesses.
