Description

technical field [0001] The invention belongs to the technical field of electrical testing, and in particular relates to an automatic testing system and method for a multi-port cable of a spacecraft. Background technique [0002] With the continuous development of spacecraft technology and the deepening of industrialization, the functions of spacecraft systems are becoming more and more complex, and the reliability requirements are constantly improving; the development time of spacecraft is gradually shortened, and the development process is more efficient. Based on this situation, in terms of spacecraft cable testing, traditional cable testing methods can no longer meet the requirements of high efficiency and reliability in the development process. Therefore, the present invention proposes an automatic test system design method for multi-port cables, and introduces the composition of the multi-port cable automatic test system for spacecraft from aspects such as the overall i...
