Research on Design of Radar Online Automatic Test System
Considering high false alarm probability of BIT and oversize of off-line ATE,the paper studies and designs an online automatic test system.The interface signals of radar line replaceable units (LRU) on working condition are leaded out by three-port conversion card and conditioned with insulation technology,making the effect of the test system on radar minimum.Then the signal is acquired by virtual instruments based on PXI bus.On software,the description document structure based on ATML standard is designed to describe te st information and parsed to binary tree for checking and revising with recursive algorithm At last,the data acquisition is achieved by LabWindows/CVI programming,calling description documents.Experiments verify the well test performance and efficiency of the test system.
