Abstract

An interlaboratory comparison of microwave power measurement (project UME-EM-10-02) was carried out among eight laboratories in Turkey. In this comparison, it was requested to make microwave power measurements at +10 dBm, 0 dBm and -15 dBm power levels with 0.03 GHz, 1 GHz, 7 GHz, 12 GHz and 18 GHz frequencies with their own measurement systems and methods. The measurement results and the expanded uncertainties were presented by the participant laboratories. Also, the normalized score (<i>E</i>_n) of each participant laboratory were calculated and presented to evaluate the performance of the laboratories. Most of the results in measuring power on a type N coaxial line show good agreement. According to the calculated <i>E</i>_n values, corrective actions were proposed to some of the participant laboratories.
