Abstract An accurate calibration method of millivolt AC voltage source based on voltage proportional and AC/DC transfer technology is proposed. The binary cascaded voltage proportional device and 792A AC/DC transfer standard are adopted to trace the millivolt AC voltage to a known AC voltage. By using a substitution measurement method,and choosing the combination of different voltage proportion and different range of 792A, the AC voltage in the range of 10~200mV of a 5720A multifunctional calibration source is accurately measured in the frequency range of 55Hz~5kHz. Results show that the relative error of any measured millivolt AC voltage is within ±40μV/V, and the expanded uncertainty is better than 80μV/V, which shows that the proposed method can meet the traceability requirements of millivolt AC voltage source.
