Abstract (in Japanese) (See Japanese page) 
(in English) The frequency band of BS/CS-IF signals has expanded for 4K8K broadcasting. However, interference with existing communication services had become a problem. Therefore, in April 2018, technical standards for leakage power in satellite receiving equipment were established. Since the reference of the leakage power is low, it was difficult to perform accurate measurement due to the effect of the internal noise of the measuring instrument. In this paper, we developed equipment to measure radio waves leaked from a satellite broadcasting receiving system in accordance with the technical standards of leakage power. Also, we reported on the performance of the measurement equipment, which has been improved compared to that of the previous prototype, such as the expansion of the dynamic range of the measurement level. The performance was evaluated with received satellite broadcasting signals.
