Abstract :
This paper describes a simple and effective technique of unloading a Josephson waveform synthesizer in quantum based ac-dc difference measurements on thermal converters using a transconductance amplifier. The new technique is particularly suitable for industrial applications. Measurements at frequencies from 5 Hz to 5 kHz demonstrate agreement with conventional standards of better than 1 μV/V.
