摘要：

This paper describes a method for calibrating an ac source using a Josephson Arbitrary Waveform Synthesizer (JAWS) by summing the sources in series and tuning the magnitude and phase of the JAWS to null the combined output voltage. The method requires an ac source that can generate a signal that is phase-synchronous with the JAWS. As a demonstration of this method, we measure the output of a calibrator at an rms output of 4 V and a frequency of 1 kHz.
