Abstract:
This paper presents the development of an automated system for the calibration of radio-frequency (RF) power meters, addressing the need for accurate, traceable, and efficient calibration in the RF domain. The system is based on a Rohde & Schwarz signal generator and reference power sensors, operating over a frequency range up to 43.5 GHz. A Python-based software solution enables full automation of the calibration process, including signal level auto-balancing and uncertainty estimation. Calibration results – such as calibration coefficients, linearity, and Voltage Standing Wave Ratio (VSWR) – are formatted into Digital Calibration Certificates (DCCs) using XML. DCCs offer a reliable, machine-readable solution for integration into Industry 4.0 systems, enhancing traceability and reducing human error. The proposed approach improves calibration efficiency and supports the global shift toward digital metrology. A user interface and example XML structure are also presented.
