Proposed ANSI RF/Microwave Standard and the Instrumentation Available to Perform Compliance Measurements.

摘要

This paper will explore the various instrumentation that has been available in the past and its relevance to the proposed ANSI standard, along with new available instruments that may significantly modify the way compliance measurements are to be performed. A sample of the changes that may occur includes high frequency (hf) monitoring where previous electric or magnetic field levels must be converted in order to add fractions of each field component to determine if allowable levels of electromagnetic energy are exceeded. The paper will also cover spatial and time-averaged surveys and required instrument characteristics for properly measuring field levels down to the 3 to 10 kHz frequency range. Unwanted characteristics of instruments will be covered, such as magnetic field out-of-band responses, modulation errors, and other measurement phenomena associated with the various methods of detecting non-ionizing radiation. Special attention will be devoted to the calibration of the monitors, the various methods of calibration available, and applicability to a particular frequency range. 4 refs., 2 figs., 1 tab.
