The Mobile Internet Wireless Communications Signal Chip Testing Machine Development

Invention and application of radio technology has more than 100 years of history. In recent years, with the development of 3G technology and a new generation of mobile Internet technology, mobile phones, tablet PCs, notebook computers and other mobile wireless communications device began to spread. Airports, hotels and other public places have begun to offer Wlan, Wifi and other services, short-range wireless transmission, wireless Internet access, instant messaging and other wireless data transmission in recent years has shown explosive growth. As the basis for wireless data transmission, wireless data transmission and reception in the information processing module, the signal encoding, mixing, amplifying, transmitting, receiving, filtering, decoding to restore the above proposed problems and new challenges more stringent requirements.Papers with Apple's latest handset testing to develop wireless communication module as a starting point, through the product features and special testing requirements analysis, in comparison to the existing test equipment, combined production capacity requirements in order for the chip development of test equipment for the main content.Based on the use of functional testing requirements and chip signal chips, choose the right test and shielding fixtures, analyze and draw test machine design.According to the test bench design of the proposed scheme, the overall layout of the complete structure of the test bench, and complete the automatic feed tray module, the transition location module, a robotic arm and a robotic arm 2 analysis and design, combined with the table layout and overall equipment required to complete machine modeling design work.According to the chip's functional test requirements, based on the development of a test bed for the chip function test, analyze test data to verify the test bench meets the requirements, and improve the testing machine and test software, depending on the data.The text of the work, starting from the functional test requirements, analysis, design complete signal chip-related test equipment and experiments verify the feasibility of the application of test equipment, to provide a sample reference for the development of test equipment similar signal chip engineering field.
