Abstract :
We present a method for calibrating the voltage that a pulse generator produces at a load at every point in the measured waveform epoch. The calibration includes an equivalent circuit model of the generator so that the user can calculate how the generator will behave when it is connected to different instruments. The calibration also includes a covariance-based uncertainty analysis that provides the uncertainty of each sample and the correlations between the uncertainties at the different time points. Given the calibrated waveform and its covariance matrix, various pulse parameters and their uncertainties can also be calculated.
