The low-frequency interface test is characterized by strong repeatability and requires accuracy and meticulousness. It is most suitable to use a computer instead of a manual to complete such a task. Therefore, automated testing is an inevitable trend in the development of satellite low-frequency interface testing. After continuous development, in the satellite low-frequency interface automatic test system, the interface test tool has been developed from a discrete transfer box, a multimeter, and an oscilloscope to an interface tester integrating an oscilloscope, a multimeter, and an automatic contact switching device. The test mode develops from manually operating test tools and manually recording test results to starting to use the test system to automatically execute test documents, operate test tools and record test results. The introduction of automated testing greatly improves the efficiency and quality of interface testing.

The form and structure of the test tabular document in the existing interface automated test system inherits the manual test Word tabular document format, and the test form contains test input information (contacts, criteria, instruction numbers), test method steps, and test results. The main problem is that the file template is fixed, and the specific test steps and instrument control steps are written into the system code. If you need to add a template or change the test method or update the hardware device, you need to change the system code. Poor adaptability to new interfaces, new test methods, and new instruments and equipment.

With the development of satellite technology, the types of satellite interfaces are increasing, and at the same time, the interface tester is developing towards miniaturization. To realize the generality of the system.
