AC Josephson Voltage Standard Error Measurements and Analysis
Charles J. Burroughs, Samuel Benz, Paul Dresselhaus
The Josephson arbitrary waveform synthesizer can be used as a precision voltage source for both ac and dc signals. Recent improvements in circuit designs have resulted in output voltages greater than 100 mVrms so that we can investigate ac metrology measurements in the frequency range from 1 kHz to 50 kHz. In this paper we present experimental measurements of several significant error sources that must be considered in order to create an intrinsic ac voltage standard at these frequencies. These results and the corresponding theoretical analysis allow us to move toward creating a practical ac Josephson voltage standard.
