Evaluation of the Zero-Compensation Method Based on the Comparison of Two Pulse-Driven Josephson Voltage Standards

摘要

This paper reports on a comparison of two pulse-driven Josephson voltage standards using the zero compensation pulse-bias method. Each system produces a sinusoidal voltage with an RMS signal amplitude of 10 mV for signal frequencies up to 500 kHz. By comparing the results to measurements using the conventical pulse-bias method, we can evaluate the improvements in the absolute accuracy of the synthesized AC signal of each system as well as in the deviation between both systems at signal frequencies above 10 kHz.
