[0002] The strength of the background noise signal in the radio frequency communication system in the mobile terminal has a decisive effect on the quality of the signal. The stronger the strength of the background noise signal, the smaller the signal-to-noise ratio of the useful signal. Therefore, how to test the strength of the background noise signal and reduce the noise floor It is very important to limit the signal strength within the required range to improve the signal-to-noise ratio of the useful signal. The traditional coupling noise test method uses an external antenna close to the terminal to receive the noise and connect it to a spectrum analyzer for analysis. This method requires an additional external antenna, and the external antenna Receive gain and frequency selection make the tested noise information not truly reflect the coupled noise intensity received by the mobile terminal

Abstract

The invention discloses a mobile terminal and a test method therefor. The mobile terminal comprises an antenna unit, a test connection unit and a radio frequency unit. The test connection unit is connected with the antenna unit and the radio frequency unit. The test connection unit is used for connecting the antenna unit with a probe terminal of a test device in a first test mode, and disconnecting the antenna unit from the radio frequency unit, and is also used for connecting the radio frequency unit with the probe terminal of the test device in a second test mode, and disconnecting the antenna unit from the radio frequency unit. Through adoption of the mobile terminal, the strength of coupling noise received by the antenna unit in the mobile terminal and the conduction index of the radio frequency unit in the mobile terminal can be tested accurately.
