摘要:
An apparatus for studying the electromagnetic behavior of an electromagnetic wave-emitting or electromagnetic wave-receiving tool is provided. An anechoic chamber is configured to receive the tool as well as a person handling the tool. At least one analysis antenna is configured to pick-up the electromagnetic waves emitted from or received by the tool. Signals outputted by the analysis antenna are processed, and a radiation diagram associated with the electromagnetic tool is displayed. The radiation diagram is displayed inside the anechoic chamber so that the person handling the electromagnetic tool observes how the handling of the tool affects its electromagnetic behavior.
摘要:
A device determines at least one characteristic of electromagnetic radiation emitted from a test object. A support receives the object. A network of probes is distributed along a substantially circular arc, and the support is disposed in a plane formed by the network of probes or in a plane parallel to the plane formed by the network of probes. The network of probes or the support is pivoted in the plane formed by the network of probes or in the plane parallel to the plane formed by the network of probes about a point located in that plane to vary an angle formed between a given one of the network of probes and the support, and thereby allow measurements to be taken at plural angular positions of the network of probes relative to the test object.
