This document provides recommended test methods for assuring the radio frequency (RF) immunity of electronic devices and systems that might experience susceptibility from general use transceivers or the RF ambient.

This recommended practice provides a method for in situ immunity testing of electronic devices and systems that are installed and operated at the locations where they are used, as well as where they experience interference. The primary source of the electromagnetic (EM) energy is from transmitters that are authorized to be used, as they are in compliance with regulatory requirements. Another source is the general ambient EM environment from a variety of sources. The ambient EM environment can be characterized via a site survey using the techniques found in IEEE Std 473™. In laboratory testing, the product is exposed to RF energy (conducted or radiated) over ...

There is a need to evaluate the in situ radio-frequency (RF) immunity of electronic devices and systems. This recommended practice focuses on installation environments that have experienced interference when exposed to portable or ambient RF sources. System aging is another reason for in situ testing. A number of aging mechanisms can degrade the initial immunity of installed equipment over its operational life. Periodic in situ testing can help verify that the required level of immunity continues to be in place over the operating life of a system. In particular, if interference is exhibited suddenly, the equipment immunity should be re-evaluated using the mo...
