The EAST transient electric field measurement system is designed for detecting the distribution and intensity of the transient electric field while the EAST is discharging, and can provide the basis for electromagnetic compatibility (EMC) design. It is composed of monopole electric-field probe, photoelectric isolation device, NI data acquisition equipment and software developed on LabVIEW to deal with the data. By testing, it can make synchronous data acquisition with sixteen analog channels, 20MHz sampling rate and up to 650MB?s-1 throughput separately, which is able to meet the demand of acquiring, processing and storing the real-time data in the high-frequency analog signals multi-channel mode.
