Abstract

Abstract

Specific Absorption Rate (SAR), as a mandatory parameter for the personal safety of electromagnetic radiation involving wireless communication products, has new requirements for the validation of the measurement system as its measurement method and measurement system need to be updated due to the change of the device under test. Based on the in-depth understanding of the validation methods in the current standard, the validation methods of the three traditional validation steps, namely, Extrapolation routine verification, Probe linearity verification and others, are measured and analyzed through electromagnetic simulation and experimental measurements, and the validation methods are extended by combining with the new requirements of the new test. The measured results show the feasibility and stability of the extended verification method. Since the reference values are obtained by the self-developed method, the validation method can be extended and the validation configurations, such as the validation points, can be customized according to the needs. This provides technical support for the study of the validation method for new and domestic SAR measurement systems.
