ABSTRACT
Firstly,the research purpose,significance,research status and development about test of volt-ampere characteristics of electronic components were introduced in this paper, and it briefly describes the main contents and program issues;For the design of the transistor-based virtual instrument test,firstly about virtual instrument technology, LabVIEW 8.5 graphical programming software and data acquisition design it make a brief introduction,through some knowledge the issues related,which writes the principle and algorithm of the design of diode and triode current characteristic measurement,and a circuit diagram more clearly illustrates the measurement principle; Finally, the paper introduces the process of building of hardware circuit and measuring operation, and it made a certain conclusion.
The main content of the paper is designing the experimental program based on virtual instrument technology and universal data acquisition card to complete the test of the transistor characteristic.The traditional measurement methods require multiple measuring instruments, which is bound to affect the experimental results and causes some errors.The application of Virtual Instrument Technology make computer hardware resources and instrumental hardware an organic integration.By the respectively actual measurement of model IN4148 diodes and model 2SC9014 transistors,it prove that it meets the requirements of test experiments.The design mainly applys voltage scanning method and Monte-Carlo method.
