Automated setup for calibration of calibrators at alternating voltage and alternating current

Calibrators are compact devices generating reference values for voltage, current, resistance and other quantities and are mainly used to calibrate measuring devices. Especially for AC quantities, there are wide parameter ranges for the generated values and frequencies, so that the traceable calibration of calibrators is a challenge. Different approaches have been investigated in order to design an automated setup to offer a calibration service for calibrators.
