Improved reproducibility of conducted emission measurements

For the improvement of the reproducibility of conducted EMI measurements, Artificial Mains Network (AMN) specifications as well as the description of test methods are to be amended. For the AMN impedance, a tolerance of the phase is being specified in addition to the tolerance of the magnitude. Also a minimum isolation between power and EUT ports is proposed as well as a minimum attenuation of 10 dB on the receiver port. For the test setup, guidelines for effective grounding of the AMN including guidelines for the avoidance of ground loops will be given. As a result of some further investigations on cable layout, meandering of the EUT cable is preferred to bundling.
