Abstract: The traditional electric-field sensor test systems have some disadvantages such as complexity,inefficiency and bad compatibility.This paper designed a new electric-field sensor test system.Based on NI PXI and LabVIEW,virtual instrument system architecture was given by this test system.Based on DCS,the controller and operation station are separated,the standard electric-field controlling,data acquisition and processing can be realized.Based on the technique of correlation detection,it can measure the calibration of electric-field sensor in static and alternating electric field.Through experiments,the test system has been proved to have strong stability and high measuring accuracy less than 1%.

Key words: PXI,MEMS,Electric-field sensor,LabVIEW
