Description
To setup bridge between design and production, develop test system according to designer's requirements, implement automatic mass production test, not only meet the RF test requirement from designer, i.e. the ability and accuracy of the test system can meet or exceed the performance of the DUT, but also reduce test time to meet production line's requirement.
For new project, to design test solution, develop TD-SCDMA and LTE TDD base station production test system, setup lab verification test environment to verify the correctness and accuracy of the production test.
For maintenance project, to on line support current GSM, WCDMA, TD-SCDMA base station production, analyze any problem during mass production, locate and solve the problem either product it self or caused by test system.
Qualifications
