Abstract :
This paper presents an intelligent test system for power amplifiers by using virtual instrument technology. The automatic range switching circuit and Hall current transducers are applied in this system, realizing effectively the measurement of wide-voltage signal and large current. LabVIEW, a graphical programming language, and expert system technology are employed to develop testing software, implementing performance test of sonar power amplifier parts, and measurement of technique index and fault diagnosis. The proposed system has been used in the certain type sonar power amplifier system. The test results show that flexibility and data processing capacity of test instruments are improved upon greatly, which can satisfy more needs of measurement. And the proposed system can detect and locate the fault position quickly
