This paper presents a simple method for comparing the impedance of an artificial mains network (AMN) with the International Special Committee on Radio Interference (CISPR) 16-1-2 standard. The circuit of a vector network analyzer, which is an impedance measurement instrument, is not ideal, and the measured impedances include measurement uncertainties. However, complete uncertainty analysis is not required in the proposed method. By comparing the relative relationship between the measured impedance of an AMN under test and the measured impedance of the original transfer standards whose impedance is modeled by the regulated impedance in the CISPR 16-1-2 standard, conformity to the standard can be determined. The magnitude and phase of the impedance of an AMN can be independently analyzed. To demonstrate the method, we apply it to a commercially available AMN. The comparison result is found to be equivalent to the result based on a complete uncertainty analysis, which confirms that the proposed comparison method is feasible.
