EMC Antenna Calibrations

Antenna Calibrations for Electromagnetic Compatibility (EMC) Testing: SAE ARP 958D, ANSI C63.5-2017, CISPR 16-1-6:2017, and YOU!

By Doug Kramer, Director, Lab Services, ETS-Lindgren, Cedar Park, Texas

Abstract: The landscape of EMC testing provides a wide variety of different requirements and test methods. Calibration is the process used to provide the traceability on measurement to the International System of Units (SI).  Depending on the product testing method and writing body, the three most commonly referenced documents for antenna calibration are CISPR 16-1-6, ANSI C63.5, and SAE ARP 958.  This is a presentation of the three documents most commonly used by EMC testing standards for the calibration of an antenna, how to specify those services as you need them, and when to know the difference.

Loop Antenna Calibration within the CISPR 16 Series

By Alexander Kriz, Seibersdorf Laboratories, Seibersdorf, Austria

Abstract:  Several standards of the CISPR 16 series are currently under maintenance by CISPR/A.  Radiated emission measurement methods (CISPR 16-2-3), antenna specification and test site validation techniques (CISPR 16-1-4), and antenna calibration methods (CISPR 16-1-6) are updated for the frequency range below 30 MHz. This presentation provides a summary of the most important changes and the corresponding impact on EMC test labs.  The focus will be on loop antenna calibration.
