Abstract

This paper presents the results of a comparative analysis of the calibration factor measurements of the power sensor model E4413A, manufactured by Agilent, which operates at frequencies from 50 MHZ to 26.5 GHz and power levels from -70 dBm to +20 dBm. The comparison takes into account the values of the calibration certificates provided by INPE’s Integration and Testing Laboratory (INPE/LIT) and two others calibration laboratories: National Physical Laboratory (NPL) of United Kingdom and Brazilian Calibration Laboratory of Agilent. The normalised error is used to evaluate the performed power measurements. Conclusive analysis of the results presented in this paper shows the compatibility and the reliability of the measurement values provided by INPE/LIT.
