Automatic calibrator for multi-parameter physiological signal simulator

The utility model relates to an automatic calibrator for a multi-parameter physiological signal simulator and aims to solve the technical problems such that during measurement calibration for the ECG (electrocardiosignal) or multi-parameter physiological signal simulator at present, the use of a temporary setup method causes signal instability, failure of adjustment of magnification times, low efficiency, low precision, instable performance and failure of tracing. A signal input interface is directly connected with the simulator to be calibrated, a calibration output interface is used to calibrate measurement of the simulator to be calibrated, and accordingly time and voltage references are traced back; multiple parameters, such as frequency and voltage, of the simulator to be calibrated, are traced back to the level of national standard of metrology, a communication interface is connected with an upper computer, and accordingly calibration data is directly converted into calibration recordings and storage. The automatic calibrator has the advantages of high integration level, high accuracy, high measurement precision, capability of being full-automatically operated and the like; comprehensive measurement calibration and tracing is fully achieved for the multi-parameter physiological signal simulator.
