Performance Evaluation of Prototype Measurement Equipment for Leaked Radio Wave from Receiving System of Satellite Broadcasting

Abstract

The technical standard of leaked radio waves in the intermediate frequency band (2.2 GHz to 3.2 GHz) was stipulated , which is applied 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 a wideband modulated signal and its power is weak . We proposed the measurement method for the leaked wave from the receiving system. From the performance evaluation of the prototype measurement equipment, we confirmed that the measurement accuracy of the proposed system was less than 3 dB when the power level of the leaked wave was equal to the technical standard.
