Abstract |
The report describes the construction of an automated absolute field generation system using standard gain horns and an anechoic range. The system operates in the frequency range of 1.12 to 26.5 GHz. The primary purpose of the range is automated evaluation of the frequency response and isotropy of various commercially available microwave hazard survey meters. |

Contents Notes |
The Nonionizing Radiation Branch of the U.S. Environmental Protection Agency conducts a program to assess environmental exposure levels of radiofrequency fields and to develop regulatory standards to limit the exposure of the general population to these fields. An essential element of this program is the maintenance of an electromagnetic field measurement instrumentation calibration and evaluation capability. This report describes a development project of a standard gain horn anechoic range system for evaluating the response of broadband, isotropic microwave measurement probes to accurately know electromagnetic fields. This prject involved the development of a computer controlled system for generating, known electromagnetic field intensities. This system provides a convenient and accurate method to evaluate measurement probe response to microwave fields and therefore establish uncertainty limits for instrument readings obtained in hazard survey measurements. |
