Near-Field Measurement System Based on a Software Defined Radio
By
Progress In Electromagnetics Research Letters, Vol. 102, 87-94, 2022
Abstract
This article reports an SDR (software-defined radio) operating as a receiver for near-field measurement, aiming at EMC pre-compliance tests. The SDR replaces professional-grade RF instrumentation with benefits, with the lower costs. Its software application is based on Open-source GNU-Radio, which grants a higher versatility to the signal processing and visualization, requiring a single laptop to analyze the data and control the whole system, in real time. Reported tests used two commercial PCB magnetic field probes, and a proof-of-concept near-field imaging is performed in an S-shaped transmission line at 1100 MHz.
