Description / Abstract:
Vehicle electrical/electronic systems may be affected when
immersed in an electromagnetic field generated by sources such as
radio and TV broadcast stations, radar and communication sites,
mobile transmitters, cellular phones, etc. Reverberation method is
used to evaluate the immunity of electronic devices in the
frequency range of 400 MHz – 18GHz. Pulse modulation is used for
testing above 800 MHz.
This document provides the component design and test engineers
with a test procedure and the performance requirements necessary to
evaluate the immunity of electronic devices to radiated
electromagnetic fields early in the design stage as well as pilot
and production stages. Ensuring electromagnetic compatibility early
in the development stage will minimize costly changes later in the
program and will prevent excessive component level hardening during
full-vehicle level testing.
The reverberation test method performs a dual function:
The primary function of the method is to provide a bench test
procedure correlatable to vehicle-level radiated immunity testing
in the anechoic chamber and at mobile transmitter sites.
The method can be used to evaluate the relative performance of
different designs of the same device.
