摘　　要：数字T/R模块自动测试系统由仪表和信号通道共同完成测试任务,而对于这样测试系统,长期以来基本采用仪表校准来替代系统校准,存在一定问题和认识误区。为了对系统进行全面的校准,提出仪表校准和信号通道校准相结合的方法,阐述了测试系统原位校准过程。通过应用验证,该方法完成对数字T/R模块自动测试系统整体性能的判定,同时对其他测试系统校准也具有参考价值。The test task is accomplished by the instruments and signal channel together in the Automatic Test System of digital T/R module. For a long time the instrument calibration is simply adopted instead of a system calibration for this test system, but it have some problems and cognitive mistakes, this text put forward the method combining the instrument calibration and the signal channel calibration in order to take an all-sided calibration for the system, elaborated the process of the in-site calibration. By application examples, the method can fulfill the system in-site calibration and realize the whole performance judgment for the Automatic Test System of digital T/R module, and it also has reference value to oth- er test systems.
