Noise in measurement data received/transmitted from/to a measurement module is reduced. A measurement control unit (10) controls circuits (50a, b) to be measured and acquires measurement data from the circuits (50a, b) to be measured. Moreover, a CPU (20) controls the measurement control unit (10) via a bus (40). Since the CPU (20) does not directly control the circuits (50a, b) to be controlled, no data is passed between the CPU (20) and the measurement control unit (10). Accordingly, a control signal and the like transmitted by the bus (40) is not mixed in the measurement data and the control signal and the like transmitted from the CPU (20) does not become a noise, thereby reducing the noise in the measurement data.
