Abstract
An error factor determination device includes an error factor recording unit which records error factors Eija in a signal generation system which includes a signal generation unit for generating a signal and an output terminal for outputting the signal, a reflection coefficient deriving unit which derives a reflection coefficient Xm of the output terminal based on measurement results Rand Rof the signal while the signal is being output from the output terminal and the error factors Eija recorded in the error factor recording unit, and a true/false determination unit which determines whether the recorded error factors Eija are true or false based on the derived reflection coefficient Xm, and a true value of the reflection coefficient.
