Abstract
Measurements of the ac-dc difference of a thermal converter have been performed using a Josephson waveform synthesizer and a precision buffer amplifier at frequencies from 10 Hz to 4 kHz, showing agreement with conventional standards of better than 1 μV/V. Also discussed is a method of finding the operating parameters of the programmable Josephson array that correspond to minimal uncertainty.
