ABSTRACT:
There is provided a calibration apparatus for calibrating an electronic device that outputs a demodulation signal in which a modulated component of a signal to be tested or evaluated is demodulated, having a DC component detecting section for detecting a DC component of the demodulation signal, a gain calculating section for calculating a gain in the electronic device based on the DC component of the demodulation signal and a calibrating section for calibrating the electronic device based on the gain in the electronic device.
