Metrological Characterization of EMI Receivers

This paper compares different hardware architectures of electromagnetic interference (EMI) receivers with respect to their calibration in a metrology laboratory. Basic tests for checking the receivers' compliance with the CISPR 16-1-1:2019 standard are described and practical aspects of their performance are presented. It is shown that testing of time-domain EMI receivers popular in many EMC testing areas (e.g., pre-compliance testing) for their conformity with the standard in a metrology laboratory is currently more time-consuming and not properly supported by the standard compared to traditional swept-frequency systems.
