Testing instruments for comparing two digital signals to obtain error data do not exist at present, and meanwhile, special calibrators for detecting electronic transformers outputting low voltage signals do not exist at present either. The invention discloses a calibrator which can be simultaneously applicable to detecting the electronic transformers and traditional transformers from multiple manufacturers. The calibrator is characterized in that digital signal input ends and analog alternating current signal input ends are arranged on the calibrator body; at least two digital signal channelsand at least two analog signal channels are installed in the calibrator body; the analog signal channels comprise programmable amplifying circuits, self-calibration circuits, high-speed frequency division sampling hold circuits and high-speed A/D measuring circuits; the digital signal channels comprise photoelectric signal conversion modules; and synchronizing signal generators and receivers are arranged between the signa
