| Abstract: | Considering the harsh requirements for test environment, complexity of the opration and expensive cost, an EMI near-field test system is designed based on virtual instrument. The main hardware architecture is composed of near-field probe and spectrum analyzer. The system used the interactive interface design on LabWindows/CVI to realize the unified management of test project, and also accomplished the control of spectrum analyzer and design of data acquisition module respectively by VISA and NI-DAQmx. System can meet the requirements of non-standard EMI test and improve the test efficiency with the superiority of short development cycle and strong compatibility. The technology and methods adopted in the system are practical and worthy of using abroad. |
