It is fixed.Due in test, there is the test channel of multiple frequency ranges, in order to find noise spot as soon as possible, will be whole in the present embodiment
The test channel of section frequency range carries out being divided into multistage frequency range test channel.
Typically before disturbed test, equipment to be tested (mobile phone) is set up into communication connection by shielding box and comprehensive test instrument.
Comprehensive test instrument：It is mainly used in analog real network and mobile communication.Mainly include GSM, GPRS, CDMA,
Option is applied in the mobile phone test of TDSCDMA, LTE.
Shielding box：It is mainly used in shielding external interference signals, while the communication set up between mobile phone and comprehensive test instrument, is mobile phone
One of main tool of coupling measurement.
In addition, the first state and the second state in the present embodiment can be the free positions of mobile phone, for example, bright screen shape
State, screen state of going out, camera opening, camera closed mode, using opening, using closed mode etc., this implementation
Example is not defined to the implication that particular state is specified, and is that equipment to be tested is gone out screen state with first state, and the second state is to treat
Test equipment is illustrated as a example by opening shooting head status.
S102, if the difference of the sensitivity of first state and the second state is more than or equal to predetermined threshold value, obtains difference big
Channel is tested in the target frequency bands equal to predetermined threshold value；
Predetermined threshold value can be the default threshold value of tester, for example, 2dB, 3dB etc., the present embodiment is not specific to its
Numerical value be defined, it is also possible to different threshold values settings are carried out according to different states.
If the difference of the sensitivity of first state and the second state in a certain frequency range test channel is more than or equal to default
Threshold value, is thinking that frequency range test channel is that target frequency bands test channel.
S103, detects the sensitivity of equipment to be tested third state in target frequency bands test channel, if the third state
The difference of sensitivity and the sensitivity of first state is more than or equal to predetermined threshold value, then confirm that target frequency bands test the sensitivity of channel
Disturbed by first state.
Wherein, the third state can be the state opposite with first state or be the opposite state of the second state, for example
In first state for equipment to be tested is gone out screen state, the third state is equipment bright screen state to be tested.
Disturbed test method provided in an embodiment of the present invention, is tested in channel by equipment relatively more to be tested in same frequency range
Two differences of state Sensitivity, there is the test channel of the target frequency bands of interference problem in accurate acquisition, then by obtaining mesh
Two states are compared with the difference of the sensitivity of the third state with predetermined threshold value respectively in the test channel for marking frequency range, and
It is determined that there is corresponding state during interference, overcome is carried out one by one to each state in multiple frequency ranges test channel in the prior art
Time-consuming for test during test, determines the slow problem of disturbance state；In addition by two disturbed test two-in-one of state, reduce and survey
Examination number of times, determines that target frequency bands test channel, and the most interference frequencies of covering reduce the testing time.
It should be noted that terminal involved in the embodiment of the present invention can include but is not limited to personal computer
(Personal Computer, PC), personal digital assistant (Personal Digital Assistant, PDA), wireless handheld

Specifically, adjustment mobile phone is screen state of going out, the sensitivity that the frequency range tests channel is tested；Open camera, test
The frequency range tests the sensitivity of channel.
S204, judges whether first state and the sensitivity difference of the second state are more than or equal to predetermined threshold value, if so, then holding
Row step S205, otherwise continues executing with the test channel that step S202 is adjusted to other frequency ranges to be tested by comprehensive test instrument；
S205, obtains target frequency bands test channel of the difference more than or equal to predetermined threshold value；
It will be appreciated that in first state (screen state of going out) and the sensitivity difference of the second state (camera opening)
During more than or equal to predetermined threshold value, illustrate that the sensitivity of the frequency range mobile phone screen and camera has interference.
S206, detects the sensitivity of equipment to be tested third state in target frequency bands test channel；
Wherein, the third state is bright screen state.
S207, judges that the sensitivity of the third state and the difference of the sensitivity of first state are more than or equal to predetermined threshold value, if
It is then to perform step S208；Otherwise, step S209 is performed；
S208, confirms that the sensitivity of target frequency bands test channel is disturbed by first state.
S209, confirms that the sensitivity of target frequency bands test channel is disturbed by the second state.
Illustrated so that predetermined threshold value is as 3dB as an example, wherein the predetermined threshold value in step S204 and step S207 can phase
Together, it is also possible to different, the present embodiment is not made a distinction by first the second predetermined threshold value of predetermined threshold value box.
Scheme provided in an embodiment of the present invention, this specifies channel under testing go out screen state and camera open mode respectively
Sensitivity, when the difference between some channels twice measurement result is not less than 3dB, it is believed that now screen or camera are in the letter
Road produces interference to mobile phone receiving sensitivity.There is sensitivity under interference channel bright screen state by test again and go out under screen state
Sensitivity, compare difference between the two, if channel difference twice between test result is not less than 3dB, sentence
Trunk snap is disturbed to be produced by screen；If channel difference twice between test result is less than 3dB, judge that interference is by imaging
Head is produced.
Camera disturbed test and the disturbed test two-in-one of screen are reduced testing time by such scheme；Specify optimal
Test interval, the most interference frequencies of covering, reduces the testing time；Automatic test is capable of achieving, manual testing's cost is reduced,
Improve efficiency.
The embodiment of the present invention further provides the device embodiment for realizing each step and method in above method embodiment.
