- Brand: USB data acquisition card
1A brief introduction to the application and function of the product
USBSA800It is a high-speed data acquisition card with USB interface. The card has multiple analog input channels (asynchronous). The card has many trigger functions, such as external triggering and internal triggering. The software interface is flexible and convenient, users can quickly configure the operating parameters of the card, and can collect and store data in real time. USBSA800 adopts large capacity SDRAM cache technology, large-scale FPGA technology and high-speed USB interface technology. It has the advantages of high accuracy of AD conversion, fast data transmission speed, good reliability and abundant software support. It can be widely used in laboratory or measurement and control system.
