There is a need for high-order frequency measurement without greatly increasing consumption currents and chip die sizes. A semiconductor device includes: an electric power measuring portion that performs electric power measurement; a high-order frequency measuring portion that performs high-order frequency measurement; and a clock controller that supplies an electric power measuring portion with a first clock signal at a first sampling frequency and supplies a high-order frequency measuring portion with a second clock signal at a second sampling frequency. The second sampling frequency is higher than the first sampling frequency.
