Of TD-SCDMA terminal RF conformance test system in the unit responsible for construction work, this article is of thinking and summing up the above work. Of full participation in the structures of the test system, including standard, the test method to determine the selection and integration of test system hardware and software part of the test system design and development. Terminal test field, the current state is dominated by foreign manufacturers, which most mainstream Agilent (Agilent), the United States and Germany RS (Rohde \u0026 Schwarz), 2G play a leading role in the era of the GSM and CDMA and 3G WCDMA and CDMA2000 standard, they were to develop their own RF Conformance certification system, but the price is more expensive for China's development in terms of the more frail terminal manufacturers and R \u0026 D enterprise is more difficult to accept. In addition, TD-SCDMA, they are still waiting to see the standard can to the communications market do not have enough confidence in how much cake. This makes us more steadfast confidence in the self-developed TD-SCDMA the terminal RF test system. Starting from the TD-SCDMA terminal RF conformance test standards, through research and design a practical application of the value of the TD-SCDMA terminal RF conformance test system, the system can support the standards set forth in the transmitter, receiver performance HSDPA and HSUPA indicators test. System hardware, through the tender selection instrument, basically select the instrument of a higher cost of well-known manufacturers in the world, which is the cornerstone of the system software development. System software using a modular design concept, the system software is divided into the user interface, test planning, test plan execution, test data processing control five functional modules and test instruments, and using the GPIB interface functions and GPIB interface phase set match the Standard Commands for Programmable Instruments (SCPI), remote operation and control of test instruments. In this paper, the major functional modules of the software design, structure and processes in detail. So far, the TD-SCDMA terminal RF conformance test system platform development work has been completed, and after more than 2 years of network testing tasks of inspection. During this time the system get better optimization. This communication standard to alleviate the relatively weak status of the TD-SCDMA terminal testing and support of independent intellectual property rights in our country has a very important practical significance.
