Operating Margin Measurements for an AC Josephson Voltage Standard
For a number of years, NIST has been developing a Josephson arbitrary waveform synthesizer as an ac Josephson Voltage Standard (ACJVS). The effort has primarily focused on increasing the output voltage to practical levels. Recent advances in circuit design and superconducting integrated circuit fabrication have enabled us for the first time to demonstrate waveforms with a 242 mV peak voltage. T...
متن کاملAC-DC Transfer Standard Measurements Using An AC Josephson Voltage Standard
NIST is implementing the Josephson arbitrary waveform synthesizer as an ac Josephson Voltage Standard (ACJVS). Over the past few years we have demonstrated precise measurements of synthesized sine waves at rms voltage amplitudes up to 170 mV. The system can generate a variety of precision voltage outputs including dc voltages and ac sinewaves, so it can be used as a quantum-based voltage source...
متن کاملAn AC Josephson Voltage Standard for AC-DC Transfer-Standard Measurements
In order to improve the National Institute of Standards and Technology (NIST) low-voltage calibration service for thermal-voltage converters, we have constructed an ac-Josephsonvoltage-standard (ACJVS) system that can synthesize accurate rms voltages of up to 100 mV. Using this system, we synthesized dc voltages and audio-frequency sine waves in order to measure ac–dc differences on the 22 mV a...
متن کاملAC-DC Transfer Standard Measurements and Generalized Compensation with the AC Josephson Voltage Standard
We present ac-dc transfer standard measurements using the NIST pulse-driven ac Josephson voltage standard source. We have investigated the frequency dependence for several output voltages up to 200 mV for frequencies from 2.5 kHz to 100 kHz. We found that as the frequency increases, the ac-dc differences for the two arrays on the same chip do not agree. We investigated different attempts of imp...
متن کاملJosephson Voltage Standard Comparison Automation
To ensure the uniformity of the representation of the volt based on KJ-90, a series of key comparisons have been carried out by the Bureau International des Poids et Mesures (BIPM) under the auspices of the Consultative Committee for Electricity and Magnetism (CCEM) using the BIPM.EM.K10 Technical Protocols Option A and Option B for the Josephson Voltage Standards (JVS) operated by National Met...
