Abstract: The paper introduces calibration method of sampling oscilloscope risetime based on optic-electrical pulse and constructs calibration setup. The risetime of sampling oscilloscope with 30GHz bandwidth and 50GHz bandwidth is calibrated by using this calibration setup. According to experiment results, optic-electrical pulse is suitable for the calibration of sampling oscilloscope risetime with Gaussian response. According to this method, Beijing Institute of Radio Metrology and Measurement constructed calibration setup.

Key words: Calibration, Risetime, Optic-electrical pulse, Oscilloscope
