Abstract

Abstract

The wireless communication technology and standards are constantly evolving. Upgrading of the standards has brought changes in signal waveforms, which requires improvement in corresponding measurement methods. The maximum Equivalent Isotropic Radiated Power (EIRP) is the most important measurement parameter in type approval of radio transmission equipment. This paper focuses on the analysis of maximum EIRP measurement methods for the new generation of public Wireless Local Area Network (WLAN) equipment. The measured signals have a high bandwidth and a certain duty cycle. This paper proposes a time-domain measurement method and a frequency-domain trigger method. The two methods were compared and analyzed. To check measurement consistency, two widely used instruments from different manufacturers were measured. Systematic measurements and an in-depth analysis were conducted on the maximum EIPR of the instruments. The measurements and analysis can shed light on improvement in WLAN equipment measurement standards.
