| 摘要: |
| 针对合并单元缺乏时钟同步异常状况测试的现状，设计了一种测试装置，该装置既能够自产生各种IRIG-B异常信号，又能够监视外接IRIG-B信号。利用该装置组成了自动化测试系统，通过自动化闭环测试方法，校验合并单元在时钟同步信号异常的情况下各种性能表现，补充了合并单元测试的测试手段，有助于提高合并单元的可靠性。 |

| Abstract: |
| Aiming at the lack of abnormal clock synchronization test for MU(Merging Unit),a clock synchronization tester is designed, which not only can generate abnormal signal of IRIG-B, but also monitor the IRIG-B signal from external GPS device. A kind of automatic test system is constructed with the designed tester to investigate the performance of MU functions in the clock synchronization abnormal by automatic closed-loop test method, supplement the testing measurement of MU and help to improve the reliability of MU. |
| Key words: clock synchronization automatic test merging unit IRIG-B |
