Abstract
This paper introduces the framework,operation method and function of power supply module automatic testing system based on the virtual instrument technology.The system adopts multi-functional data acquisition card PXI-6052E,control module PXI-PCI833X of the NI Company and virtual instrument development platform of the man-machine interface of LabVIEW.It enables users to change its function and scale by modifying the software of the virtual instrument.This testing system can complete numerous automatic tests on the power supply module in a short time,and the result of testing is highly accurate and consistent;the user's operation interface is friendly.
