Design of the Automatic Test System for the Multi-Channel Microwave Receiving Front End System

The theory of the multi-channel microwave receiving front end is introduced in this paper. And an automatic test system for the multi-channel microwave system has also been mentioned which is set up through the LAN. The indicators of the multi-beam reconnaissance receiving front-end system that can be quickly tested and recorded by this test system includes noise factor, gain consistency, stop-band suppression, mixing spurious, harmonic, dynamic range, video signal consistency, logarithmic slope, etc. And the actual test results show that the automatic test system can efficiently and reliably achieve the function of automatic test for the system under test.
