Network testing box, network testing method and network testing analysis system

The invention discloses a network testing box which comprises the components of a processing module, a data transmission module, an antenna and a demodulating module, wherein the data transmission module, the antenna and the demodulating module are electrically connected with the processing module, wherein the data transmission module is used for acquiring a testing task which comprises at least one first frequency range that corresponds with at least one to-be-tested standard network. The antenna is used for acquiring a system broadcast message which corresponds with at least one second frequency range in a current area, and generates a system broadcast message set. The processing module is used for screening the system broadcast message which matches at least one first frequency range inthe system broadcast message set and generates a system broadcast message subset. The demodulating module is used for decoding each system broadcast message in the system broadcast message subset andacquires a testing result
