Abstract :
The measurement of VRC of a generator is presented. The "ripple technique" is used, with an air line, a directional bridge and a short. An uncertainty model is given which takes into account unwanted signals (directivity and test port match). Finally, the results are presented along with the estimated uncertainty.
