This acquisition system is an integrated solution designed for synchronous multi-channel voltage and current testing. It supports high voltage and high current measurement, with a maximum voltage input of 1000 V and a maximum current input of 20 A. Equipped with 12 independent acquisition channels, it can be centrally controlled with one-click operations via upper computer software. The system supports full-device synchronous sampling as well as independent start/stop control for each single channel. Test data can be exported with a single click, facilitating data archiving, traceability and experimental review.
