を特徴とする信号発生器。 a digital waveform generator that generates digital data of a predetermined waveform; an attenuation data generator that generates data that determines the magnitude of the output signal;
a sine wave generator that generates sine wave digital data; a multiplier; and a first sine wave generator that holds the output of the multiplier.
and a second register, a multiplexer that selects two outputs from among the outputs of the digital waveform generator, the attenuation data generator, the sine wave generator, and the first register and inputs them to the multiplier; and a DA converter that converts the output of the second register into an analog signal, and first, the multiplexer selects two of the outputs of the digital waveform generator, attenuation data generator, and sine wave generator. and input it to the multiplier, multiply it, and store the result in the first register, and then use the multiplexer to input the output of the first register and the digital waveform generator, attenuation data generator, A signal generator characterized in that an unselected output among the outputs of the sine wave generating section is input to the multiplier and multiplied, and the result is stored in the second register.
