摘要

Request to non-contact measurement method of load impedance connected to a wire harness is increasing rapidly. A method using network analyzer together with two current probes were previously proposed for this purpose, but it is valid only to 20 MHz. In this study, we extended the above-mentioned non-contact measurement method to common mode load impedance up to 100 MHz by applying transmission line theory to the wire harness. The validity of the newly proposed measurement method was confirmed experimentally, and as a result the common mode load impedance was measured with an error within 10% up to 100 MHz.
