Development Practice of LCR Automatic Test System Based on Agilent E4980A

摘要

Aiming at the complicated situation of artificial testing function materials, a set of automatic test system based on Agilent E4980A is developed. In the control software edited by Visual Basic 6.0, the test conditions (temperature, frequency, voltage, etc.) are pre-set, and the system automatically controls the temperature of the temperature control box through PID algorithm, achieving the real-time test voltage and frequency of Agilent E4980A. The card shows the readings on the test results of a plurality of functional materials at various stages of temperature conditions, automatically completing the storage and analysis of electrical parameters. The system is able to achieve the automatic control of the temperature control box and Agilent E4980A, presenting the comparative benefits including the function of this system being more comprehensive, more convenience in operation, and higher degree of automation advantages. It can be a good method and reference resource available for the development of such test system.
