Description
Technical field
It is automatic more particularly to a kind of line loss of mobile device test system the present invention relates to the technical field of mobile communication
Detecting method and its system.
Background technology
Communication equipment has many rigid standards in terms of RF index, and there is the national standard of correlation in country, and industry also has row
Even there be oneself independent tightened up company standard in the standard of industry, some companies for more remarkable quality requirements.So
In the production process of mobile device, the importance calibrating, eventually survey, couple related to radio frequency is also just apparent.Wherein, this
The line loss control of a little erect-positions is again the most important thing.
Prior art China, production system line loss control method mainly has following several：
(1) a golden machine is made, Jin Jishang is affixed on using the radio-frequency information of label record gold machine, and by label.It is actual raw
The radio-frequency information in use, on the radio-frequency information and label of measurement of comparison is produced, line loss is then changed according to the difference of the two.Its
In, golden machine refers to that an indices and parameter all reach optimal machine.If the golden machine in mobile phone is exactly for detecting system
The stable test machine of one performance comparision of error.However, this method can not realize automation, it is necessary to which operating personnel combine reality
Metrical information calculates currently practical line loss value, and operability is poor.
(2) golden machine radio-frequency information is stored in the data storage of mobile phone.Actual production by instrument in use, can be read
Radio-frequency information, and current station line loss is calculated automatically.Such as Publication No. CN201985871U, entitled《A kind of radio frequency
Line loss calibrating installation》Chinese utility model patent in i.e. a kind of RF line loss calibrating device, including computer and control are disclosed
