Disturbed equipment
Electrical devices, equipment and/or systems subject to interference and which can be adversely
affected by it are termed disturbed equipment.
In the same way as interference sources, disturbed equipment can also be categorized correspond-
ing to frequency characteristics. A distinction can be made between narrowband and broadband
susceptibility
Narrowband systems include radio and TV sets, for example, whereas data processing systems are
generally specified as broadband systems.

As previously mentioned, an interference source causes both conducted and radiated electro-
magnetic interference.
Propagation along lines can be detected by measuring the interference current and the interference
voltage
The effect of magnetic and electric interference fields on their immediate vicinity is assessed by
measuring the radiated magnetic and electric field components. This method of propagation is also
frequently termed electric or magnetic coupling (near field).
In higher frequency ranges, characterized by the fact that device dimensions are in the order of
magnitude of the wavelength under consideration, the interference energy is mainly radiated direct-
ly (far field).
Conducted and radiated propagation must also be taken into consideration when measuring the
susceptibility of disturbed equipment.
Interference sources e.g. sine-wave generators as well as pulse generators with a wide variety of
pulse shapes are used for such tests.
