| Abstract: | A new impedance test and analytical system for transducer is designed and implemented.The test and analysis software running in the host computer is developed based on Labwindows/CVI platform.The host computer communicates with a precision impedance analyzer-Agilent4294A by GPIB.It can not only display the measurement data and graph synchronously with Agilent4294A,but also save data to database.Through the data manage software,users can consult,analysis,or display the test data saved in the database and draw performance curves for these data.The application results show that the measurement data are accurate,the performance of the system is stable,and the operation is convenient. |
