Measuring Device Voltage Division Noise Calibration

The patent creates a virtual copy of the Josephson voltage standard through software simulation. Instead of requiring physical JVS equipment, the system generates simulated voltage standard values via a simulation unit that produces reference voltage values based on predetermined characteristics, thereby eliminating the need for physical installation space while maintaining calibration functionality

The patent replaces the mechanical/physical Josephson voltage standard system with an information-based simulation system. The simulation unit uses software algorithms to generate voltage reference values, substituting the physical electro-mechanical JVS apparatus with a computational model that achieves the same calibration function without spatial requirements

The patent implements self-service calibration where the measurement device automatically performs calibration procedures without requiring external intervention. The calibration unit automatically compares measured voltage values against simulated standards, and the simulation unit dynamically generates appropriate reference values, enabling the system to calibrate itself autonomously and simplifying user operation

The patent incorporates feedback mechanisms where the measurement device continuously monitors voltage measurements, compares them against simulated standards generated by the simulation unit, and automatically adjusts or reports calibration status. This closed-loop feedback system simplifies operation by automatically handling the calibration process rather than requiring manual adjustment procedures
