| Abstract: | Given to characteristics of electronic equipments test under non-standard test environment, the needs of signalacquisition and process of several typical electromagnetic interference item are investigated. The thinking of malfunction portablevirtual measurement instrument is presented. The efficient data acquisition and interface to matlab programming environment arerealized by use of LabVIEW virtual instrument programming environment. The experiment results prove that this method combineshe merit of LabVIEW and signal processing algorithms. The method, which is practical, integral and extended, removes thebackground noise dramatically and reduces the expenses of EMI test of electronic equipments. |
