specifically, the user terminal may be installed with a special application program, and the radio frequency performance test procedure is triggered manually through the application program, or the application program automatically and periodically triggers the radio frequency performance test procedure according to the setting. The user terminal controls the first modem to generate a frequency f according to the control instruction of the application program_OPower of P_SAnd then transmitted through the first antenna connected to the first modem.

In some possible embodiments, the functions of the application program may also be integrated into the system functions of the user terminal, so that the radio frequency performance test procedure may also be triggered in the option of the system functions.

In some possible embodiments, the user terminal may also establish a connection with a control host (e.g., a PC), and the control host sends a command to the user terminal to trigger the rf performance testing process.

102. The user terminal uses the f through the second antenna_OReceiving the modulated signal, and obtaining the power P of the modulated signal received by the second modem_R。

Specifically, after the modulated signal is transmitted through the first antenna, the user terminal performs common-frequency reception on the modulated signal by using the second antenna, and obtains the power P when the modulated signal is transmitted from the second antenna to the second modem_R。

103. The user terminal is according to the P_SThe P is_RPath loss P of the modulated signal_LAnd between the first antenna and the second antenna at the f_ODegree of separation L of_VThe radio frequency performance of the user terminal is determined.

Wherein, P_LIncluding the path loss of the modulated signal from the first modem to the first antenna and the path loss of the modulated signal from the second antenna to the second modem. P_LAnd L_VThe impedance matching of 50 ohm omega can be ensured by welding radio frequency cables at the feeding positions of the first antenna and the second antenna through measurement and acquisition in advance, and the radio frequency cables of the first antenna and the second antenna are connected through a network analyzer which is arranged at f_OThe S12 parameter of the measured S parameters is L between the first antenna and the second antenna_V. The path loss generated by the modulated signal from the first modem to the first antenna before being transmitted by the first antenna and the path loss generated by the modulated signal from the second antenna to the second modem after being received by the second antenna can be obtained by a spectrometer, and the sum of the two path losses can be used as P_L。

The radio frequency performance of the user terminal mainly comprises two aspects: whether radio frequency failure exists and whether radio frequency performance consistency is problematic. The radio frequency fault is generally caused by factors such as component damage, circuit open circuit/short circuit and the like, so that the power of the modulation signal is greatly attenuated in the transmission process, and even the transmission is interrupted. The consistency of the radio frequency performance is generally caused by the slight difference of the manufacturing process of the components, and the slight difference of the manufacturing process can cause the actual parameters of the components to have a certain difference with the theoretical parameters, thereby causing the power of the modulation signal to be slightly attenuated or increased in the transmission process.

The method comprises the steps of presetting a first power threshold value aiming at radio frequency faults, presetting a second power threshold value aiming at radio frequency performance consistency, wherein the preset first power threshold value is larger than the preset second power threshold value, and assuming that the preset first power threshold value is 5dB and the preset second power threshold value is 2 dB.

Specifically, the user terminal generates the power P of the modulation signal according to the first modem_SPath loss P of the modulated signal_LAnd between the first antenna and the second antenna at the f_ODegree of separation L of_VObtaining the power P of the modulated signal theoretically to be received by the second modem_S-P_L-L_VAnd obtaining the power P of the modulated signal actually received by the second modem_RTo obtain the power P of the modulation signal theoretically received by the second modem_S-P_L-L_VP of the modulated signal received by the second modem_RAbsolute value | P of the difference of_S-P_L-L_V-P_R|。

Further, if | P_S-P_L-L_V-P_RIf | is greater than or equal to 5dB (i.e. the preset first power threshold), that is, in fact, the power of the modulation signal received by the second modem is too different from the power of the modulation signal theoretically to be received by the second modem, the ue may determine that there is a radio frequency failure. If | P_S-P_L-L_V-P_RIf | is greater than or equal to 2dB (i.e. the preset second power threshold) and is less than 5dB, that is, the difference between the power of the modulation signal actually received by the second modem and the power of the modulation signal theoretically received by the second modem is relatively large, the user terminal may determine that the radio frequency performance consistency problem exists. If | P_S-P_L-L_V-P_RIf i is less than 2dB, that is, in fact, the difference between the power of the modulation signal received by the second modem and the power of the modulation signal theoretically received by the second modem is very small, the user terminal can determine that the radio frequency performance of the user terminal is good, and the radio frequency failure and the radio frequency performance consistency are not caused.

Further, when the user terminal determines that the user terminal has a radio frequency fault or radio frequency performance consistency problem, a log file can be generated for recording so as to facilitate subsequent detection of the radio frequency performance of the user terminal, preliminary fault judgment during maintenance and the like. In addition, the user terminal can also output prompt information of the user terminal with radio frequency fault or radio frequency performance consistency problems in modes of sending sound signals through a loudspeaker, sending light signals through an indicator lamp, generating vibration through a vibration motor, outputting a prompt box on a user interface and the like.

The user terminal in the embodiment of the invention comprises a first modem and a second modem, wherein the first modem is connected with a first antenna, the second modem is connected with a second antenna, and the user terminal utilizes the first modem to generate the frequency f_OPower of P_SThe modulated signal is transmitted through the first antenna and then through the second antenna_OThe modulated signal is received at the same frequency, and the power P of the modulated signal received by the second modem is obtained_RFurther according to the P_SThe P is_RPath loss P of the modulated signal_LAnd between the first antenna and the second antenna at f_ODegree of separation L of_VDeriving the power P of the modulated signal theoretically to be received by the second modem_S-P_L-L_VP of the modulated signal received by the second modem_RAbsolute value | P of the difference of_S-P_L-L_V-P_RBy mixing | P_S-P_L-L_V-P_RComparing | with a preset first power threshold and a preset second power threshold to determine whether the user terminal has a radio frequency fault or a radio frequency performance consistency problem. Therefore, the user terminal can determine the radio frequency performance of the user terminal by self-sending and self-receiving the modulation signal and according to the transmitting power and the receiving power of the modulation signal, so that the radio frequency performance test can be completed quickly, the test operability is improved, and the test cost is reduced.
