Radio frequency interference
RFI is the high frequency interference with radio reception. This occurs when
undesired electromagnetic oscillations find entrance to the high frequency
input of a receiver or antenna system.
RFI sources
Sources are equipment and systems as well as their components which can
cause RFI.
Shielded enclosure
A screened or solid metal housing designed expressly for the purpose of
isolating the internal from the external electromagnetic environment. The
purpose is to prevent outside ambient electromagnetic fields from causing
performance degradation and to prevent emissions from causing interference
to outside activities.
Stripline
Parallel plate transmission line to generate an electromagnetic field for testing
purposes.
Susceptibility
Susceptibility is the characteristic of electronic equipment that permits
undesirable responses when subjected to electromagnetic energy.
