Patent ID: 7885779

Claim:
A measurement error correcting method in which, regarding an electronic component including signal line ports connected to signal lines concerning application or detection of a radio frequency signal, and nonsignal line ports other than the signal line ports, from results of measuring the signal line ports and the nonsignal line ports, with the electronic component mounted on a test jig, an estimated electrical characteristic value of the electronic component that will be obtained if the signal line ports are measured with the electronic component mounted on a reference jig enabling measuring only the signal line ports is calculated, the measurement error correcting method comprising: a first step of, with at least three types of correcting-data-acquisition samples mounted on the test jig, and the at least three types of correcting-data-acquisition samples mounted on the reference jig, sequentially measuring an electrical characteristic of at least one of signal line ports of each of the at least three types of correcting-data-acquisition samples; a second step of preparing a correcting-data-acquisition through device in which at least one of signal line ports and at least one of nonsignal line ports are electrically connected to each other, measuring the signal line port and the nonsignal line port, with the correcting-data-acquisition through device mounted on the test jig, and measuring the signal line port, with the correcting-data-acquisition through device mounted on the reference jig; a third step of determining, on the basis of measurement values obtained in the first and second steps, a numerical expression that includes a first term for the signal line ports and a second term for the nonsignal line ports for calculating, from the results of measuring the signal line ports and the nonsignal line ports, with the electronic component mounted on the test jig, the estimated electrical characteristic value of the electronic component that will be obtained if the signal line ports are measured with the electronic component mounted on the reference jig; a fourth step of measuring the signal line ports and the nonsignal line ports, with the electronic component which is arbitrarily selected, mounted on the test jig; and a fifth step of calculating, on the basis of measurement values obtained in the fourth step, by using the numerical expression determined in the third step, the estimated electrical characteristic value of the electronic component that will be obtained if the signal line ports are measured with the electronic component mounted on the reference jig.
