Flatness and gain self-tuning device for alternating-current voltage proportion circuit

The invention relates to a flatness and gain self-tuning device for an AC voltage proportion circuit, which comprises a step voltage generation module, a signal conditioning module, a relay array, an acquisition module, a compensation circuit module and a controller, and can generate a step signal as a self-tuning input signal through the step voltage generation module. The controller is used for controlling configuration parameters of the compensation circuit module to perform frequency flatness compensation and calibration, and flatness and gain self-tuning of the attenuation proportion circuit can be performed without external equipment; the flatness and gain calibration cost of the attenuation proportion circuit is reduced, the flatness and gain calibration period of the attenuation proportion circuit is shortened, and the flatness and gain calibration convenience of the attenuation proportion circuit is improved. 本发明涉及一种用于交流电压比例电路的平坦度和增益自整定装置，包括阶跃电压产生模块、信号调理模块、继电器阵列、采集模块、补偿电路模块和控制器，可通过阶跃电压产生模块产生阶跃信号作为自整定
