The invention discloses a multichannel phased array TR assembly amplitude-phase consistency test system and test method. The system comprises a mobile terminal, a signal transfer central controller, a vector network analyzer and a pulse/code pattern generator. The mobile terminal communicates with the signal transfer central controller, the vector network analyzer, the pulse/code pattern generator and the phased array TR assembly to be tested; the signal transfer central controller is used for connecting a plurality of channels of a to-be-tested phased array TR component to the vector network analyzer; the vector network analyzer is used for testing the amplitude of a radio frequency signal of the to-be-tested phased array TR assembly and the phase of a channel, and transmitting a test result back to the mobile terminal; the pulse/code pattern generator provides synchronous pulse input for the phased array TR assembly to be tested; according to the test system and the test method, the amplitude-phase consiste
