In terms of measure principle

system structure

design scheme and experimental results

the design of USB data acquisition system of transmission error is introduced based on LabVIEW and SOPC.Aiming at characteristic of that

it is difficult to develop USB device driver

traditional methods.Thus

the USB device driver is developed in LabVIEW

and the data communication between the PC and FPGA is realized.The data is transmitted to computer and displayed

processed and stored in LabVIEW.By testing

the system is reliable and stable

and the operating results are well.
