Automatic Test And Diagnosis System for Amplitude And Phase Calibration Circuit Board Based on VXI Bus

Abstract

Based on VXI bus technology, this paper constructed an automatic test and diagnosis system for amplitude and phase calibration circuit board of monopulse radar receiving system which can test the function and performance parameters of the circuit board quickly and accurately, then give the fault diagnosis and the maintenance strategy according to the test data. The hardware platform is based on reliable VXI. The software uses the popular VB （Microsoft Visual Basic 6.0） programming language to operate the database which is programmed by SQL. The user can complete the complex test and diagnosis with the keyboard and mouse. The practice shows that the system which is universal, open, extensible and the user interface being friendly and easy to operate.
