  • Publication number: 20080010034
    Abstract: An adapter of unknown properties necessary for performing simple N-port calibration is prepared and simple N-port calibration is performed on a network analyzer using the adapter. Moreover, the open reference, short reference, and load reference are measured in succession, with the adapter in a disassembled state, at the test ports to which the adapter was connected during calibration. Finally, the calibration coefficient obtained by simple N-port calibration is corrected using the properties of the adapter found from the measured values of each reference. N is an integer of two or more.

  • Publication number: 20070241760
    Abstract: A calibrated network analyzer is re-calibrated by measuring a circuit parameter of a standard device, specifying the type of error coefficient relating to this measured circuit parameter, and calculating an error coefficient of this specified type using this measured circuit parameter. Moreover, of the circuit parameters necessary for this calculation, a circuit parameter other than this measured circuit parameter is reproduced using the theoretical value of this circuit parameter and the standard coefficient obtained by this calibration.
