Abstract
A device to measure intermodulation products of a receiver of at least two electromagnetic signals of different frequencies comprises at least two channels for the transmission of the signals of different frequencies and one reflective reception channel connected to an apparatus for the measurement of intermodulation products. The reception channel enables the transfer of signals in a frequency band centered on the reception frequency band of the receiver. A reflective reception multiplexer/demultiplexer with directional filters provides for the interconnection of the two transmission channels of the reflective reception channel of the receiver.
