Uncertainty evaluation of conducted emission measurements by means of conformal mapping

Conformal mapping is used to investigate the uncertainties of conducted emission tests on power supply lines, taking into account the requirements of test components specified by most EMC standards. Unfortunately, there is no clear common approach in the definition of the coupling devices located between the EUT (equipment under test) and the EMI receiver. Therefore, test reproducibility may be affected and an additional contribution may be added to the overall uncertainty of the test.
