An automated test system used for front-end of phased array

The phased array front-end injection test has the characteristics of huge number of unit channels, wide bandwidth and large dynamic range, while the near-field and far-field test has the characteristics of large beam scanning range, small step and complex indicators. It is of great significance to construct automated tests in phased array transmitter testing. An automatic test system, with the computer as the core, which can automatically test the functions, performance parameters, fault location and fault diagnosis of the equipment under test is introduced in this paper. With the presented automated test technology, it will save a lot of testing time and human resources, and will also prevent the negative impact of human factors on test results in the test work of front-end of phased array.
