A 10 V programmable Josephson voltage standard has enabled sine waves with voltages
up to 7 V RMS to be accurately measured with a differential sampling measurement …

For decades, the quantum behavior of Josephson junctions has been employed as intrinsic
standards for voltage metrology. Conventional dc Josephson voltage standards have been …

The discovery of the Josephson effects 50 years ago initiated a revolution for electrical
voltage metrology. This revolution started with single Josephson junctions delivering a few …

An ac quantum voltmeter based on a 10 V programmable Josephson array that is simple to

A test bench has been developed for systematic characterization of high-resolution analog-
to-digital converters. The reference signal is generated by a programable Josephson …

An RLC bridge based on an automated synchronous sampling system has been developed
using commercially available high-resolution analog-to-digital and digital-to-analog …

AC Josephson voltage standards based on pulse-driven Josephson arrays (Josephson
arbitrary waveform synthesizer—JAWS) have recently achieved an output voltage of at least …

This paper describes the development of an automated ac quantum voltmeter toward a
turnkey system, which can be used for calibration of common dc and ac voltage standards …

Differential sampling relative to a Josephson waveform, the ac quantum voltmeter (ac-QVM),
has been established as the most accurate method for measuring signals below 1 kHz with …

Two NIST programmable Josephson voltage standard (PJVS) systems are directly
compared at 10 V using different nanovoltmeters. These PJVS systems use arrays of triple …
