Research on calibration method of wideband power analyzer

A wideband power analyzer is a synthetic instrument measuring electrical parameters of power supply and applied widely in all fields of industry. Because it has characteristics of strong function, many parameters, wide wideband, large measurement range, large span of accuracy grade and so on, the daily calibration of the instrument is very complex, and all the calibration items cannot be finished by using one or more standard equipments. This article introduces the calibration method for routine calibration items of the wideband power analyzer in detail by using a standard source measurement method and a standard system measurement method.
