Performance detection system for dual-mode communication equipment

The embodiment of the invention provides a performance detection system for dual-mode communication equipment. The system comprises a radio frequency matrix which comprises at least one branching device and at least one adjustable attenuator, and is used for constructing a topological environment through the adjustment of the at least one adjustable attenuator; the signal analyzer is connected with the radio frequency matrix and is used for acquiring a signal waveform from the radio frequency matrix; the signal generator is connected with the radio frequency matrix and is used for introducingnoise into the radio frequency matrix; a center node shielding box which is connected with the radio frequency matrix through a radio frequency line and is used for placing a to-be-tested device and suppressing an external interference signal; and at least one slave node shielding box which is connected with the radio frequency matrix through a radio frequency line and is used for placing a to-be-tested device and suppres
