| TD-SCDMA(Time Division-Synchronous Code Division Multiplex Access) is the self-innovation mobile communication technology of China,which is one of the 3rd Generations,has entered the test-commerce now.In the whole industrial chain,the problem for the equipment manufacture at present is the lack of test solution which transport the R&D to produce for the moment.Due to the reason and background,after study many reference documents and with work experience,an automated test solution for TD-SCDMA RF module is useful and merit.In the paper,following contents and questions has been described.First,according to the key features and targets of TD-SCDMA RF module, the test elements have been analyzed,the test methods have been provided. Because of the particularity of TD-SCDMA,normal test methods are not suitable for some special targets.Reasonable test method for the key features such as power amplify,adjacent channel leakage power ratio,S parameters for TD-SCDMA RF module have been submitted.Second,according to the test methods,the whole test solution has been designed.Aim at the transmitter and receiver of RF module,combined the operations of RF instruments,the whole test solution can achieve the testable for all the test methods,which is prepared for the automated test program.Third,according to the analysis of auto test solution,appropriate test bus and develop tool which are General-purpose interface bus(GPIB) and LabWindows/CVI have been selected.Through the function depots supplied by the RF instrument manufacture,the General-purpose interface bus(GPIB) supplied by LabWindows/CVI,a integrated automated test solution which is programmed by general program language is accomplished, which can fulfill the demands of equipment manufacture at the moment.The automated test system which is running in the factory now can reduce the time and manpower of test obviously,doing the preparative for the extensive-commerce of TD-SCDMA.During the continuous development of mobile communication technology,automated test system also can be improved at a lot of parts to adopt future use. |
