—This paper describes a Josephson-voltage-standard-locked synthesizer where a commercial digital-to-analog converter is used as a sine wave generator. The output amplitude of the generator is controlled by the calculable fundamental of the stepwise waveform generated by a SINIS Josephson junction array. Such a system combines the versatility of a commercial(More)
A test bench has been developed for systematic characterizations of high resolution analog-to-digital converters. The reference signal is accurately generated using a programable Josephson voltage standard. Three different 24-bit digitizers have been characterized. Their noise performances have been measured in dc using the Allan deviation while the(More)
—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 converters. This bridge allows the comparison of any kind of impedance standards in the four-terminal-pair configuration at frequencies between 50 Hz and 20 kHz within a range from 1 Ω to(More)
