METHOD FOR GENERATING INTERFERENCE SIGNALS AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

Method for generating interference signals and device for carrying out said method, wherein an interference signal (1) is added, in a network (3) for combining and separating signals, to a desired signal (4) which carries a test message, the sum signal being sent to a device (5) to be tested. The interference signal (1) is generated with a single source connected to a signal splitting and conditioning block (7) which attenuates additional interference caused by the source for generating interference signals (1), while providing as many interference signals (1) as antennas (Rx, Rx/Tx) in the device (5), and wherein each interference signal (1) is sent to a respective amplification and isolation block (8) which adjusts the power level of the interference signal (1) and attenuates reverse intermodulation products caused by the transmission of signals from the device (5) under test.
