Abstract
Test equipment needed for different testing items of handset radiation is installed inside anechoic chamber. At the same time, test equipment needed for corresponding different testing items of handset radiation is installed outside anechoic chamber also. When different testing items of handset radiation are needed to carry out in same anechoic chamber, the developed program will switch connections among instruments automatically for the item to be tested to the handset. Thus, the invention can accomplish different testing items of handset radiation by switching relevant instrument in same anechoic chamber.
Description
Technical field
The present invention proposes a kind of mobile phone radiation Auto-Test System and method, it mainly is the required testing apparatus of the different testing radiation of handset projects of installing in an anechoic chamber, (Chamber), also provide in the anechoic chamber, outside simultaneously and correspond to the required testing tool of different testing radiation of handset projects, switch the project that is online to mobile phone desire test between each instrument by the Automatic Program of exploitation, can reach the purpose that different testing radiation of handset projects are finished in the switching that utilizes same anechoic chamber, to carry out the relevant device instrument.
Background technology
Known mobile phone on stream or authentication phase all need utilize anechoic chamber, to carry out various radiation test, to verify whether this mobile phone meets the demand of dependence test standard, test event has wherein comprised the antenna patterns illustrated figure test (Antenna pattern test) that places anechoic chamber, to carry out the spur signal transmission test (Radiation spurious emission test) of height different frequency range the mobile phone to be measured and equally place mobile phone to be measured in the anechoic chamber, to be done, understanding the coherent radiation characteristic of mobile phone to be measured, and borrow test result to judge whether to meet the demand of dependence test standard.
Known test laboratory is the modes that adopt a Room one test event on the framework of radiation test more, promptly an anechoic chamber, only is used for arranging in pairs or groups and carries out at the needed instrument of a certain test event, therefore in the time need carrying out different test events to mobile phone to be measured, must with online between each testing apparatus of manpower manual adjustment, testing tool and mobile phone to be measured or will this mobile phone to be measured moving to another place that is equiped with different testing apparatuss and testing tool to proceed test, this is the test mode of inconvenience very to the tester.
In order more to clearly demonstrate the known method of utilizing anechoic chamber, to carry out height spur signal transmission test of different frequency range and antenna patterns illustrated figure test, below see also the explanation of Fig. 1 and Fig. 2, Fig. 1 is known when utilizing anechoic chamber, to carry out the spur signal transmission test, the connected mode synoptic diagram of dependence test equipment and testing tool, wherein 10 first halves of the separatrix among Fig. 1 are to be illustrated in the anechoic chamber,, 10 Lower Halves then represent it is outside anechoic chamber, in the separatrix, by mobile phone 15 to be measured as can be known among the figure, high frequency receiving antenna 11 and low frequency receiving antenna 12 are to be positioned at anechoic chamber,, required surveying instrument spectrum analyzer 14 then is to be positioned at outside the anechoic chamber,, when carrying out the spur signal transmission test, need to switch between high frequency receiving antenna 11 and the low frequency receiving antenna 12 toward covering back and forth by a low-and high-frequency receiving antenna switch 13, switching by different transmission paths, the low-and high-frequency signal that will be received from mobile phone 15 to be measured respectively is sent to spectrum analyzer 14, in order to analyzing whether mobile phone 15 to be measured produces spur signal and so as to producing relevant data information, this connected mode on known way can by one independently anechoic chamber, carry out.
Please continue to consult Fig. 2 again, Fig. 2 is that the known anechoic chamber, that utilizes carries out antenna patterns illustrated figure when testing, the connected mode synoptic diagram of dependence test equipment and testing tool, wherein 10 first halves of the separatrix among the figure are to be illustrated in the anechoic chamber,, 10 Lower Halves then represent it is outside anechoic chamber, in the separatrix, by mobile phone 15 to be measured as can be known and high frequency receiving antenna 11 among the figure is to be positioned at anechoic chamber,, and required surveying instrument network analyzer 16 is to be positioned at outside the anechoic chamber,, then received signal sending network analyser 16 is analyzed with the relevant aerial radiation field pattern figure data of output when testing when carrying out antenna patterns illustrated figure by a high frequency receiving antenna 11, this connected mode on known way can by one independently anechoic chamber, carry out.
Aforementioned testing radiation of handset mode needs more is carried out under a fixing test environment, as the high frequency connecting line between dependence test equipment and testing tool in the anechoic chamber, being fixed, will cause the geometric configuration of tie line to change, influence the accuracy and the accuracy of measurement result.
Comprehensive aforementioned analysis as can be known, no matter known measuring mobile phone radiation mode is to carry out spur signal transmission test or antenna patterns illustrated figure test, both required measuring systems and measuring method are all very similar and all need carry out just passable in anechoic chamber,, therefore if when carrying out different test events in known manner, then must maybe will this mobile phone to be measured move to the different test spaces and proceed test, promptly can produce following problem thus with online between each testing apparatus of manpower manual adjustment, testing tool and mobile phone to be measured:
1. dependence test equipment between each test event and the online switching of testing tool are difficult for, and cause the complexity of testing process to improve.
2. frequent high-frequency joint dismounting easily causes the damage of high-frequency joint.
3. therefore the high frequency connecting line that connects each instrument and equipment increases high frequency connecting line geometric configuration and changes correction uncertainty and the accuracy that is caused because of placing the fixed position.
4. increase regular emending frequency, increase correcting process.
5. increase required manpower and the time of test process.
6. reduce the service efficiency of anechoic chamber.
Therefore the present invention carries out the foregoing problems that produced when spur signal transmission test and antenna patterns illustrated figure test in order to solve known mobile phone, a kind of mobile phone radiation Auto-Test System and method are proposed, this system and method mainly is the required testing apparatus of the different testing radiation of handset projects of installing in an anechoic chamber,, also provide installing to correspond to the required testing tool of different testing radiation of handset projects simultaneously in the anechoic chamber, outside, and Automatic Program that cooperate to utilize exploitation in advance switches the project that is online to the test of mobile phone desire between each instrument, reaches the purpose that different testing radiation of handset projects are finished in the switching that utilizes same anechoic chamber, to carry out the relevant device instrument.
Summary of the invention
