Test Procedures:
A Conducted RF Immunity test was performed using the mode of operation and configuration noted
within this report. The source of disturbance covered by the standard is basically an electromagnetic
field, coming from intended RF transmitters, that may act on the whole length of cables connected to
installed equipment. The dimensions of the disturbed equipment, mostly a sub-part of a larger system,
are assumed to be small compared with the wavelengths involved. The ingoing and outgoing leads: e.g.
mains, communication lines, and interface cables, behave as passive receiving antenna networks
because they can be several wavelengths long. The use of coupling and decoupling devices to apply the
disturbing signal to one cable at a time, while keeping all other cables non-excited, can only
approximate the real situation where disturbing sources act on all cables simultaneously, with a range of
different amplitudes and phases. Coupling and decoupling devices are defined by their characteristics.
Any coupling and decoupling device fulfilling these characteristics can be used.
