    • Noise in measurement data received/transmitted from/to a measurement module is reduced. A measurement control unit (10) controls circuits (50a, 50b) to be measured and acquires measurement data from the circuits (50a, 50b) 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, 50b) 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.
    • 降低了从测量模块接收/发送的测量数据中的噪声。 测量控制单元(10)控制要测量的电路(50a,50b),并从要测量的电路(50a,50b)获取测量数据。 此外,CPU(20)经由总线(40)控制测量控制单元(10)。 由于CPU(20)不直接控制要控制的电路(50a,50b),所以在CPU(20)和测量控制单元(10)之间没有数据通过。 因此,由总线(40)发送的控制信号等不在测量数据中混合,并且从CPU(20)发送的控制信号等不会变成噪声,从而降低测量数据中的噪声 。
