[0002] The airborne RF circuit board is mainly used in the aviation communication navigation identification system, mainly to realize the functions of amplification, filtering and frequency mixing of the antenna port signal. The existing RF circuit board is tested along with the overall test of the product. After a failure, it is necessary to make a corresponding transfer The equipment is attached to the product for testing. A simple discrete instrument test platform consisting of an oscilloscope, a multimeter, and a spectrum analyzer needs to be built during the test. At the same time, the test parameters of the intermediate nodes need to be compared through a good board. This conventional test method has a repair cycle. Long, low work efficiency and other characteristics
