A measurement method for antenna terminal intermodulation sensitivity

The method proposed antenna terminal intermodulation sensitivity measurement method, belongs to the measurement technology field, the method is according to the requirements and methods of the 15 k ~ 10 GHz antenna terminal intermodulation conduction sensitivity test (CS103) of the GJB152A-97, based on the automatic test system, through make sure of the initial electrical level of signal source to produce reference standard output level at tested equipment tuning frequency place, and adjusting the frequency of the first signal source, calculation frequency points of the second signal source that may produce intermodulation interference, adjust the amplitude of the second signal source and scan frequency points, this method makes automatic test system able to locate intermodulation frequency points quickly and accurately, thus greatly shortened testing time.
