A Novel Software for Automatic Calibration Factor Measurement of RF Power Sensors

Abstract

In this letter, a software for calibration factor (CF) measurement of radio frequency (RF) power sensors (PS) by using VNA-based direct comparison transfer method (VBDCTM) was developed on C# platform. Measurements were performed between 10 MHz and 18 GHz frequency range. When the calibration factors calculated with conventional CF measurement method and novel software were compared, a maximum difference of 4.56% was found in the 10 MHz – 18 GHz frequency band. Therefore, the automatic CF measurement software based on VBDCTM, which has less complexity, can be preferred to conventional method for measuring the calibration factor of power sensors.
