Background
At present, the development of spacecrafts in China enters a new period. With the dual requirements of product lead time and quality, satellite products have gradually shifted from custom units to general shelf spectrum units. In particular, in recent years, the requirement of batch high-quality delivery of networking satellites such as Beidou satellite and the like causes serious conflict between the completeness of test coverage of a single machine and the delivery cycle. In order to adapt to new development characteristics and changes of satellite products, a universal automatic test system matched with the satellite products is formed, and test tasks are completed in a multi-way, quick, good and economical mode.

At present, a common measurement and control system test system integrates low frequency, baseband and radio frequency on hardware, but the hierarchical automation test is not widely applied. The main reason is that due to the high reliability and particularity of satellite products, the user-defined manual test requirement and the automatic test requirement of a test system exist at the same time, the conversion rate from the traditional implementation process of manual sending and manual interpretation to automatic execution is not high, a large amount of time is consumed, and human errors are easily introduced.

At present, a test system of a measurement and control system generally completes low-frequency interface configuration through an interface configuration interface, a system configuration interface completes measurement and control system definition, and then, traversal of test scenes is performed one by one after various parameters are manually configured. The first two steps are short in time but complex and need to be confirmed by operators to ensure the testing effectiveness, the last process is mainly repeatable operation, the time consumption is long, the recorded data is more, misoperation is easy to occur, and the testing efficiency can be greatly improved by realizing automatic testing.
