Abstract

The technical standard of leaked radio waves in the intermediate frequency band (2.2 GHz to 3.2 GHz) will be applied, which is used for receiving the 12-GHz band satellite broadcasting in Japan. However, it is difficult to measure the leaked radio wave with a conventionally measuring instrument because the leaked radio wave is weak and wideband modulated waves. In this study, we proposed the measurement method for the leaked wave from the receiving system. As a result, we confirmed that the measurement accuracy of the proposed system was less than 1.8 dB when the power level of the leaked wave was 10 dB lower than that of the technical standard.
