Calibration system of analog digital converters AC voltage and method of synchronization

摘要

Calibration system of analog digital converters AC voltage and method of synchronization.The present invention describes a system for calibration of AC voltage for analog digital converters, digital analog converters DACs and characterization of ADCs, in order to ensure the traceability of calibrations of the low frequency a.c. voltage, below 1 kHz.For a wave synthesizer programmable Josephson as well as a method of synchronization of phases of alternating current.
