Abstract
We herein propose a calibration method for a sampling oscilloscope. The proposed method can correct the systematic errors in the oscilloscope such as time-based distortion and impedance mismatch. In addition, it can accurately estimate the residual jitter that remains after a time-based correction and the scale factor that varies in accordance with the setting of the pulse generator. The proposed method is validated thorough the comparison and verification with the power meter, and the uncertainty of the measurement method is analyzed.
