Method of generating interference signals and device to carry out such a method

摘要

A method for generating interference signals and a device to carry out said method, in which an interference signal (1) is added in a signal combination and separation network (3) with a desired signal (4) that carries a test message, the sum signal being sent to a device being tested (5). The interference signal (1) is generated with a single source connected to a signal divider and conditioner block (7) that attenuates additional interference produced by the source of generation of interference signals (1), while providing as many interference signals (1) as the device (5) under test has antennas (Rx, Rx/Tx), and in which 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 the reverse intermodulation products produced by the transmission of signals by the device (5) under test.

1. A method for generating interference signals used to generate an interference signal that is added in a signal combination and separation network with a desired signal that carries a test message, the sum signal being sent to a device being tested, provided with multiple signal reception and transmission/reception antennas, the method comprising:
generating the interference signal by a single source of generation of interference signals, wherein the interference signal is connected to a signal divider and conditioner block that attenuates additional interference produced by the source of generation of interference signals, the signal divider and conditioner block providing at an output as many interference signals as the device under test has antennas; sending each interference signal obtained in the signal divider and conditioner block is to a respective amplification and isolation block, the amplification and isolation block adjusting a power level of the corresponding interference signal and attenuating the reverse intermodulation products produced by the transmission of signals by the device under test; directing the interference signals to respective networks; and adding the interference signals with the desired signal.
