Extraction of deterministic and random LSI noise models with the printed reverberation board

The main features of the printed reverberation board are revised and the methodology to extract an LSI noise model for electromagnetic radiation estimation at frequencies above 1 GHz with the printed reverberation board is presented. A test PCB has been designed and fabricated to verify the feasibility of the method. Measurement results are presented and discussed for two variations of the model: the deterministic and the random LSI models.
