A Voltage Calibrator based on programmable Josephson Arrays

A Voltage Calibrator based on a 10-V programmable Josephson Array that is simple to use, provides DC and AC calibration up to kHz range for industry-common equipment, and ensures direct traceability to a quantum-based standard, is under development. This device has proven to excel conventional DC standard systems and will extend into low frequency AC range, thereby making itself a practical and robust system that suits the needs of general metrology industry.
