ABSTRACT:
A high-precision, multi-port compatible, relative correction method and apparatus for correcting measurement errors covering an increase in the number of ports of a non-coaxial electronic component, in which a relative correction adapter31is provided that is formed of a two-port network connected to each port of a production test fixture5B adjacent to a measurement apparatus. The relative correction adapter has a characteristic that modifies the electrical characteristics generated by the production test fixture5B having an electronic component under test mounted thereon into electrical characteristics generated by a standard test fixture5A having the electronic component under test mounted thereon. An error factor of the relative correction adapter31is identified from a standard test fixture measurement value and a production test fixture measurement value of a correction data acquisition specimen11B. A production test fixture measurement value of the electronic component under test11A is corrected with the error factor of the relative correction adapter31to thereby obtain the standard test fixture measurement value of the electronic component under test11A which is assumed to be obtained when the electronic component under test11A.
