ERROR FACTOR IDENTIFICATION DEVICE, METHOD, PROGRAM, RECORDING MEDIUM, OUTPUT CORRECTION DEVICE HAVING THE DEVICE, AND REFLECTION COEFFICIENT MEASURING DEVICE

WIPO Patent Application WO/2008/026483

A1

It is possible to easily perform calibration of a signal generation system such as a switch branching signal source. An error factor identification device (20) includes: an error factor recording unit for recording an error factor (Eija) in a signal generation system (100) having a signal generation unit (12) for generating a signal and an output terminal (19a) for outputting a signal; a reflection coefficient derivation unit (24) for deriving a reflection coefficient of the output terminal (19a) according to signal measurement results (R1, R2) in the state when a signal is outputted from the output terminal (19a) and the error factor (Eija) recorded in the error factor recording unit; and a true/false judging unit for judging true/false of the recorded error factor (Eija).
