Abstract
The invention relates to a switching device comprising a matrix having connection points and integrated test means comprising two pairs of generators/detectors which are pairwise controlled in such a way that the transmission paths traversed by the RF test signals from the generators to the associated inputs of the matrix and from the outputs of the matrix and to the associated detector are of the order of length of a single side of the switching matrix.
