Abstract

The invention relates to the technical field of antenna feeders, and more specifically relates to a high interference resistance antenna feeder tester control method. According to the high interference resistance antenna feeder tester control method, reference signals and measurement signals simply and effectively realize and greatly improve interference resistance of an antenna feeder tester through a mixer, a ceramic filter, hardware phase comparison and power comparison, and the processing difficulty of software is reduced. The 455KHz general ceramic filter is applied to the antenna feeder tester, and the interference resisting capacity of the antenna feeder tester is improved simply and effectively.

Description

technical field [0001] The present invention relates to the technical field of antenna and feeder lines, and more particularly, relates to a control method for a high anti-interference antenna and feeder line tester. Background technique [0002] When using the antenna feeder tester to test the antenna feeder system, external noise signals are easily coupled into the system under test through the antenna, feeder or other methods. Therefore, as an antenna and feeder tester, it is required to have a certain filtering ability for the noise outside the frequency point it tests, otherwise it will seriously affect the test effect. At present, the antenna and feeder testers on the market use various methods to suppress noise interference, all of which are inseparable from the digital processing of the software. [0003] At present, the antenna and feeder testers on the market have better interference ability, basically cover the interference noise power by strengthening the power ...
