摘要

(With Figure 1 it releases) As for this invention, n port measurement (here n, N in order to decide the dispersion parameter of the measuring object the integer 1) of making use the measurement port (N it was connected to the measuring object here the integer 1) the high-frequency measurement device which is included (the HF measurement device), especially, in regard to the method of calibrating the vector network analyzer, or the high frequency test signal (the HF test signal) to supply to the 1st electric lead wire which is connected to the circuit which includes the measuring object, vis-a-vis each port, at 1st connection position, and from 1st connection position specifiedPutting in place distance, at the 2nd connection position which distribution facilities is done, along on the 2nd electric lead wire which is connected to the measuring object it is transmitted, on the especially plane surface lead wire the HF signal which coupling out does the HF signal which is transmitted from the 2nd electric lead wire, from two HF signals which coupling out are done, in each port, vis-a-vis each measurement position or connection position, facing toward the direction of the measuring object at two connection positions on the 2nd electric lead wire is transmitted, and the amplitude for, the HF test signal of the HF signal which along on the 2nd electric lead wire is transmitted to the direction which leaves from the measuring object and/Or to decide phase, then, dispersion parameter of the measuring object is calculated. Here, putting in place specified distance mutually vis-a-vis at least one of the ports of the HF measurement device, at least at three which distribution facilities is done connection positions, on the 2nd electric lead wire coupling out it does the HF signal which is transmitted, it decides one for at least one frequency of the HF test signal as the measuring object whose dispersion parameter is known making use of the specified calibration method of using vis-a-vis the combination which at least forms the respective opposite of three connection positions, at least one calibration standard, dispersion parameter at least, it forms all opposites in one frequency of the HF test signalAt least by value of one which is decided vis-a-vis combination dispersion parameter and the fact that you use calibration standard as the measuring object it was obtained, this comparing with the known value of one dispersion parameter at least, it was obtained by value of the dispersion parameter which is decided and the fact that you use calibration standard as the measuring object, it retains as the desirable 1st and 2nd connection position where it confronts this frequency in the combination which forms the opposite of the connection position to which difference with known values of dispersion parameter becomes smallest, measuring the unknown measuring object.
