Abstract

In order to improve the NIST low-voltage calibration service for thermal voltage converters, we have constructed an ac Josephson voltage standard system that can synthesize accurate rms voltages up to 100 mV. Using this system, we synthesized dc voltages and audio frequency sinewaves in order to measure ac-dc differences on the 22 mV and 220 mV ranges of a commercial thermal transfer standard. By modifying the output resistance of the low-pass-filtered transmission line, we were able to extend our measurement frequency from a few kilohertz up to 100 kHz. Our acJVS measurements agree with the uncertainty budget of ac-dc difference calibrations made of this transfer standard using conventional techniques. We also show progress toward extending the output to 200 mV using new Josephson circuits.
