The new method of measurement of the integrated characteristics, based on formation of two additional voltage signals and definition of instant values of an entrance voltage and a current at the moment of transition of additional signals through a zero is considered. Results of the analysis of an error of parameters measurement because of a deviation of real signals from harmonious model are examined.
