基于LabVIEW仿真了模拟电子电路实验中的负反馈放大电路，通过信号发生器给电路提供信号源，利用数据采集卡采集电路输出信号，然后用 LabVIEW 显示分析处理了采集信号，并计算了电路的静态工作点。对其中的数据采集部分设计了两种方案，利用GDS-3152数字示波器结合LabVIEW和经济实惠的Microchip数据采集卡对电路的输出波形分别进行采集分析，通过比较两者的优缺点选择出了GDS-3152数字示波器结合LabVIEW的方案进行仿真设计，结果显示仿真效果较好。

Based on LabVIEW,the paper does simulation of analog electronic circuit experiment of negative feedback amplifier. The circuit signal source is provided by the signal generator. It uses data acquisition card to gather circuit output signal, and use the LabVIEW to display signal analysis and processing of the collection. Then, calculate the static operating point of the circuit. For the part of data collection, the paper designes two programs, the use of GDS-3152 Digital Oscilloscope combine LabVIEW and relatively affordable Microchip data acquisition card circuit collect output waveform and analysis were carried out respectively. By comparing the advantages and disadvantages, the program of GDS -3152 LabVIEW combining digital oscilloscope is selected to do simulation design and simulation results show better. Finally, the Web of LabVIEW is designed and the installation applications is generated. It facilitates distance learning and applications.
