Abstract: Aimed at the problems of heavy workload and large devices consumption in electronic circuit experiment classes, which cause bad experimental effect to students. A virtual electronic experiment system is developed based on LabVIEW and Multisim software. LabVIEW has many advantages, such as various input controls and output displays, and Multisim has the characteristic of simple circuit design, the experimental system coupled with the advantages of the two kinds of software. Differential amplifier circuit in analog electronic experiment has as the example, the communication are achieved between the two kinds of software.

Key words: electronic experiment, LabVIEW, Multisim, joint simulation
