Abstract :
This paper provides a brief introduction to the hardware configuration and the measuring principle of microwave auto-measurement system, and gives more details on the design of the data acquisition card based on the system. The card has a high accuracy which is owed to 12-bit high sampling AD converter and 12-bit multi-channel DA converter being applied, and it takes CPLD as the control core, USB as the interface, which achieves the speedy and reliable data transmission between the data acquisition card and the PC.
