Point positioning method based on the occurrence of intermodulation initial phase passive control system and

The present invention discloses a phase control based on an initial passive intermodulation point positioning method and system occurs. Initial phase controlled using multiple RF signal source generating a reference signal along a passive intermodulation known initial phase and multiplexing passive intermodulation signal excitation, the excitation signal power after amplification are input into a combiner device under test, to generate passive intermodulation signal filtering and passive intermodulation of the filtered signal as compared to a reference phase obtained by measuring the phase difference, and corrects the phase difference signal transmission path is fixed, to obtain the device under test in the passive intermodulation signal excitation generating phase change information on the complete passive intermodulation positioning point occurs. The present invention, by designing the initial phase of the RF signal source controlled multi-channel, to achieve a control signal source for the excitation of the initial phase, the device may also be used in high power setpoint passive intermodulation occurs.
