In order to improve the transmission error testing speed as well as the real-time testing and precision,mean while,to optimize the structure of hardware circuit and to ensure that the datas sampled to translate to PC with no lossing,a method of high-speed and real-time testing has been developed. In addition,a method of transmission error testing been put forward based on a thought of pulse interpolation.By building a part of data preprocessing and a control module in a high-performance FPGA chip while a USB3.0 chip serves as the transmission medium.The system reduced the complexity of the external circuit effectively and the developing difficulty.The result of a simulation experiment shows that a FPGA is used to translate the datas caculated from the designed error curve to the system,after that,the proccessed datas needn’t to be post compensated and the error curve would back to zero again,while the curve reflects the situation of simulation experiment in the low-speed part.It shows that the system realizes the high-speed and real-time testing,and provides the technical support for transmission error testing in the future.
