Anti-jamming A/D chip design for GNSS receiver is still in the initial stage in China, so there is no mature chip index system and testing method for reference. The chip testing technology is discussed in this paper. The main function and architecture of the chip are summarized, and the corresponding test index system is established according to the requirement of application, a complete test system is set up and the corresponding test method is put forward. The research results of this paper have been applied to the actual chip test and achieved good results, which has important engineering reference value.
