The Research And Implementation Of Communications Equipment Feature Test System

The design of the communication device on the performance test is a very important task, in the test of the completion of the production, it is need to verify the performance and reliability whether corresponding with the design targets quickly. In recent years, digital technology as the main stereotypes of communications equipment. The new device features high integration, indicators and more, into mass production, units bound to the production cycle high demands. The manual testing is slow, error, low accuracy. In order to quickly meet the test requirements, it is necessary to establish an appropriate test environment based on automated test program.Papers relevant background from the test, analysis and summary the needs. Combined with the automatic test technology theory, had communications equipment performance testing of the overall program design, determine the test project, including synchronization probability test, voice testing, data testing and interface circuitry input and output impedance tests. Around the application, the proposed test system design and overall program requirements, the division of the module from the hardware.In this paper, based on the engineering practice, design the testing equipment.The device based on PC test platform, including the baseband, audio and data interface unit three interfaces. Microcontroller as the core, the baseband modem module, signal source module, single-chip test module, impedance and level test module, self-test module, interface modules and other components. In the known synchronous system conditions, using the test control software can synchronize the device under test probability, voice and data communication functions, the radio interface to input and output impedance, input and output power equal performance with limited functionality and can be indicative of the test, test data can be automatically returned test center display, save and print, greatly improved work efficiency. Finally, based on the actual testing environment to verify the equipment. This equipment performance tester has good prospects for development and practical value.
