Abstract :
The papers deals with the influence of the calibration jig to the impedance measurement result. The goal is to characterize two different designs of calibration jigs and to correct the LISN impedance accordingly. Without proper correction there is a large difference of the phase angle. It is found that the correction works properly. However the results are not without ambiguity, due to the lack of the definition of a measurand. Assumptions regarding a suitable calibration plane must be made for proper phase angle measurements.
