摘要：An active antenna test system comprising an active antenna unit comprising: atest signal generator arranged to generate at least a first test signal and at least onesecond test signal; a plurality of transmitter modules operably coupled to the test signalgenerator wherein the plurality of transmitter modules are arranged to simultaneouslyprocess the first test signal and at least one second test signal to produce at least oneradio frequency test signal therefrom; and at least one receiver module arranged toprocess one or more signals falling in at least one spectral band determined to besusceptible to intermodulation distortion products caused by the at least one radiofrequency test signal being generated from the first test signal and at least one secondtest signal; and an intermodulation determination module operably coupled to the atleast one receiver module and arranged to determine a first received intermodulationperformance. A first transmitter module of the plurality of transmitter modules isoperably uncoupled from the test signal generator and at least a first test signal and atleast one second test signal re-applied to the remaining transmitter modules, such thatthe intermodulation determination module determines a second received

intermodulation performance in order to determine an intermodulation distortioncontribution of the first transmitter module therefrom.
