The application discloses a switching device of a phased array antenna testing system and a testing method, relates to the field of phased array antenna testing of satellite communication, and discloses the switching device, which comprises a communication interface, a signal processing assembly and a darkroom testing system. The communication interface is configured with a communication protocol, the darkroom testing system and the phased array antenna follow the communication protocol, and the communication connection between the darkroom testing system and the phased array antenna system is realized through the communication interface. The signal processing assembly stores a testing file for testing the phased array antenna, controls the operation state of the darkroom testing system and switches the working state of the phased array antenna according to the testing file. Meanwhile, the probe of the darkroom testing system is controlled to collect the radio frequency signals of the phased array antenna under different working states according to the switched working state of the phased array antenna, the radio frequency signals are analyzed, and testing data are obtained. The application does not need to stop the work of the two-part system, reduces the testing waiting time, and further improves the testing efficiency.
