Technical field
The utility model relates to the test macro of a kind of testing mobile phone radio frequency interoperability (calling IOP in the following text).This system can each function of testing mobile phone to the interference of mobile phone receiver or transmitter and the phase mutual interference between each transceiver of mobile phone.
Background technology
Enter 21 century, mobile phone is at the Working and life styles that progressively changes us, and simultaneously, the mobile phone terminal technology has obtained the development of advancing by leaps and bounds.Mobile phone has been not only a simple means of communication, along with the development of its intellectuality, entertainment orientation, the increase of increasing function, range of application and the field of mobile phone progressively enlarge, become the indispensable instrument of people, we routine work and the life in play indispensable effect.Such as: listen to the radio programme, listen to the music, see a film, play games, surf the Net, photograph etc.And the network formats of same mobile phone support is also more and more, and integrated level is more and more higher.For example: NOKIA700 supports GSM850, GSM900, GSM1800, GSM1900, WCDMA (I, II, IV, V, VIII), bluetooth (BT), wireless lan (wlan).Most of mobile phone can use in 2G and 3G network simultaneously, has now had to support the mobile phone products of 4G network to sell on market.one slight mobile phone of step but has so powerful function, problem of the thing followed is so, when the mobile phone open video, music, during the function such as camera or cell-phone charging, when mobile phone passes through the Bluetooth transmission data, or use WLAN to carry out data when downloading, can or can not affect the speech quality of mobile phone? what kind of impact be that a kind of even several functions while running background can have to reception or the emission of mobile phone signal? more serious consequence is, during other function effects of the mobile phone that is moved simultaneously when the performance of mobile phone receiver or transmitter, mobile phone receiver or transmitter performance variation, being embodied in customer-side is exactly the quality of speech signal variation, even lose and be connected with the base station, and cause the termination of calling.So, just need to carry out the checking aspect this in the R﹠D process of mobile phone or before coming into the market, the namely IOP of mobile phone test.Although be badly in need of carrying out the IOP test in mobile phone research and development and production process, the IOP method of testing also is in conceptual phase up to now, does not realize standardization, there is no the relevant industries standard of IOP test, is all the self-defining method of testing of producer and standard.In the test for the IOP of mobile phone, also exist problems.For example, in field tests, general mobile phone manufacturer does not set up standard and there is no complete IOP test macro, the engineer just according to single test request with a part of instrument test system building simply, this test macro of temporarily building is not only wasted time and energy and is easily caused the damage of instrument, and the consistency of system is poor, often affects the accuracy of test result.On the other hand, for the test of IOP, do not have in the industry unified testing standard, the test specification that does not also have regulations to abide by, this all can cause the inaccurate even mistake of test result.
The utility model content
In order to overcome the above problems, the applicant conducts in-depth research and comprehensively analyzes the IOP measuring technology as the third party laboratory of communication products test, on existing measuring technology basis, has researched and developed the IOP test macro at home and abroad.
The technical solution of the utility model is as follows:
1, a kind of mobile phone radio frequency HIST system, described system comprises shielded box, mobile phone fixed station, main antenna, potato masher antenna, comprehensive test instrument, interference source, connection cable and computer; It is characterized in that:
Described fixed station, main antenna, potato masher antenna are arranged in shielded box, and comprehensive test instrument is connected with potato masher antenna with main antenna respectively by RF cable with interference source; And be connected to computer by the GPIB control line; Described comprehensive test instrument has many, and communicates by different antennas and tested mobile phone.
Further, described comprehensive test instrument comprises 2G/3G comprehensive tester, bluetooth comprehensive tester, WLAN (wireless local area network) signaling and non-signalling tester, and test specification comprises GSM, TD-SCDMA, WCDMA, CDMA, BT, WLAN.
Further, be furnished with absorbing material in described shielded box.
Further, described system has expansion interface, and when test event increased, described expansion interface connects antenna increased antenna amount.
The beneficial effects of the utility model are: realize the HIST in the mobile phone R﹠D process, comprised each function of mobile phone to the interference of its receiver or transmitter, and the mutual interferometry between each transceiver of mobile phone.Realize automatic measurement, improved accuracy, consistency and the operating efficiency of test result.Reduced the impact that measurement result is brought due to personnel's misoperation; Can help the research staff, each function of Measurement accuracy mobile phone to the interference of mobile phone receiver or transmitter and the phase mutual interference between each transceiver of mobile phone, is found out interference source in the mobile phone R﹠D process, makes assessment, improves properties of product; When test event increases, can by increasing antenna amount, reach new test request, and not need to change the entire system structure.The test function expansion is simple.
