Method of generating a scenario of electromagnetic noise for monitoring the reliability of a sensitive apparatus, characterized in that it includes the steps consisting in: defining environmental electromagnetic conditions relating to the environment of the sensitive apparatus, determining a positioning of the sensitive apparatus in the environment, and generating, on the basis of the environmental electromagnetic conditions and of the positioning of the sensitive apparatus, a scenario of electromagnetic noise including a set of permanent noises and a set of transient noises.

Method of generating a scenario of electromagnetic noise

Measuring device () for the electromagnetic field emitted by an apparatus being tested (), including a support () being mobile in relation to the apparatus being tested, at least one electromagnetic sensor () fixed to the support and driving elements () capable of rotating the support around the apparatus being tested, characterized in that it includes at least one light source () adjacent to the electromagnetic sensor and capable of emitting light according to the electromagnetic field measured by the electromagnetic sensor.

Measuring device for the electromagnetic field emitted by an apparatus being tested

A device for detecting the presence of an object in a detection zone is provided. The device includes a transmission line, a generator which is connected to an input of the transmission line and which is able to generate an input signal, and a receiver which is connected to an output of the transmission line and which is able to measure an output signal, the transmission line being able to radiate a radiated signal in the detection zone when the generator generates the input signal, the detection device further including analysis means which are able to detect the presence of an object in the detection zone in accordance with the output signal.

Device and method for detecting the presence of an object

A testing device for measuring radiation, immunity and electromagnetic characteristics of an object to be tested ( ), includes a conductive structure ( ) enclosing a testing volume where the object can be placed, the structure being provided with an opening ( ) capable of being closed. The testing device further includes a set of internal conductors called septa ( ), at least two in number, each septum defining in the testing volume, by its configuration in the structure, an electromagnetic coupling with the object; at least a septum is arranged in such a way that its electromagnetic plane is separate and not parallel to the electromagnetic plane of at least another septum.

Electromagnetic compatibility testing device

In an information transmission device and method for systems using radiating waveguides along which a mobile travels, an unmodulated carrier wave is injected into the radiating waveguide. Some of the energy of the unmodulated carrier wave is sampled locally along the radiating waveguide. A local modulation signal representing information addressed to the mobile modulates the unmodulated carrier wave. The modulated carrier wave is radiated to the mobile.
