Referring to Fig. 1, being a kind of flow diagram of radio frequency performance test method provided in an embodiment of the present invention.Radio frequency performance test method as described in this embodiment, applied to user terminal, which includes the first modem and second modem, which connect with first antenna, the second modem is connect with the second antenna, this method comprises:
101, it is f that user terminal, which emits the frequency that the first modem generates by first antenna,0, power PSModulated signal.
Wherein, to guarantee the modulated signal that can receive wherein side transmitting between first antenna and the second antenna with frequency, about frequency f0Selection it is as follows:
According to definition of 5.2 chapters and sections of TS 36.521-1 V12.3.0 (2014-09) to communication work frequency range in 3GPP agreement, frequency division duplex (Frequency Division Duplex, FDD) frequency range includes: Band1~Band31, time division duplex (Time Division Duplex, TDD) frequency range includes: Band33~Band43.

Specifically, special application program can be equipped on the user terminal, radio-frequency performance testing process is automatically periodically triggered according to setting by manually passing through the application triggers radio-frequency performance testing process or the application program.It is f that the user terminal controls first modem to generate frequency according to the control instruction of the application program0, power PSModulated signal, then the first antenna by connecting with first modem launches.
In some possible embodiments, the function of the application program is also desirably integrated into the system function of the user terminal, to can also trigger radio-frequency performance testing process in the option of system function.
In some possible embodiments, which can also establish connection with control host (such as PC), send instruction to the user terminal by the control host to trigger radio-frequency performance testing process.
102, the user terminal passes through the second antenna f0The modulated signal is received, the power P for the modulated signal that second modem receives is obtainedR。
Specifically, the user terminal does the modulated signal using the second antenna and receives with frequency, and obtains power P of the modulated signal from second antenna transmission to the second modem when after the modulated signal is launched by the first antennaR。
103, the user terminal is according to the PS, the PR, the modulated signal path loss PLIn the f between the first antenna and second antenna0The isolation L at placeVDetermine the radio-frequency performance of the user terminal.
Wherein, PLPath loss and path loss of the modulated signal from second antenna to the second modem including the modulated signal from first modem to the first antenna.PLAnd LVIt can be obtained in advance by measuring, RF cable is respectively welded at the feed of the first antenna and second antenna, to guarantee the impedance matching of 50 ohm of Ω, the RF cable of the first antenna He second antenna is connected by Network Analyzer, the Network Analyzer is in f0S12 parameter is the L between the first antenna and second antenna in the S parameter that place measuresV.The path loss generated during before by first antenna transmitting from first modem to the first antenna by the available modulated signal of the instrument such as frequency spectrograph, and the path loss that the modulated signal generates during receiving the second modem from second antenna after being received by second antenna, the sum of the two path losses can be used as PL。
Wherein, the radio-frequency performance of the user terminal mainly includes two aspects: with the presence or absence of radio frequency impairments and radio-frequency performance consistency with the presence or absence of problem.Wherein, radio frequency impairments are generally caused by factors such as component damage, open circuit/short circuits, and modulated signal power in transmission process is caused substantially to be decayed or even Transmission.And radio-frequency performance consistency is generally caused by the nuance of component manufacturing process, the nuance of manufacturing process can make the actual parameter of component and theoretical parameter have certain difference, and then modulated signal power in transmission process is caused to have slightly decaying or increase.
Wherein, the first power threshold is preset for radio frequency impairments, presets the second power threshold for radio-frequency performance consistency, which is greater than default second power threshold, assuming that default first power threshold is 5dB, which is 2dB.

Further, if | PS-PL-LV-PR| it is greater than or equal to 5dB (i.e. default first power threshold), that is the power difference of the actually second modem power of the modulated signal received and the modulated signal that theoretically second modem should receive is excessive, then the user terminal can determine itself there are radio frequency impairments.If | PS-PL-LV-PR| be greater than or equal to 2dB (i.e. this default second power threshold), and be less than 5dB, i.e., actually the power of the modulated signal that receives of the second modem with theoretically should The power difference for the modulated signal that second modem should receive is larger, then the user terminal can determine itself there are radio-frequency performance consistency problems.If | PS-PL-LV-PR| it is less than 2dB, that is the actually power of the modulated signal that receives of the second modem and the power difference very little for the modulated signal that theoretically second modem should receive, then the user terminal can determine that the radio-frequency performance of itself is good, and radio frequency impairments and radio-frequency performance consistency problem is not present.
Further, which is recorded in order to the radio-frequency performance of the subsequent survey user terminal there are journal file when radio frequency impairments or radio-frequency performance consistency problem, can be generated determining itself, and failure when maintenance tentatively judges.In addition, the user terminal can also be made a sound signal by loudspeaker, optical signal is issued by indicator light, vibration is generated by vibrating motor, exporting the user terminal in modes such as user interface output prompting frames, there are radio frequency impairments or the prompt informations of radio-frequency performance consistency problem.
