发明名称 電磁波計測装置及び電磁波計測方法
摘要 It is an object to provide an electromagnetic wave measuring apparatus and an electromagnetic wave measuring method that suppress deterioration in sensitivity of electromagnetic noise in electromagnetic wave measurement. An electromagnetic wave measuring apparatus includes a sensor that detects an electromagnetic wave and outputs a detection signal having intensity corresponding to the magnitude of energy of the detected electromagnetic wave, a resistor connected to the sensor, a first variable capacitor connected to the sensor, a voltage detection circuit connected to the sensor, a second variable capacitor connected to a wire between the sensor and the voltage detection circuit, and a capacitance adjusting unit that adjusts capacitance values of the first variable capacitor and the second variable capacitor. The electromagnetic wave measuring apparatus adjusts, in the adjusting unit, the capacitance values of the first and second variable capacitors and performs electromagnetic wave measurement.
