41 3 第 ( , , , ; 2 Beijing Shangwei Technology Co. Ltd Beijing 100089 China , , , ) In order to extract the two orthogonal components of RF signal for analysis A high speed configurable Abstract , - multi channel data acquisition system based on Aurora is designed based on the embedded high speed serial - - transceiver module. The system can change the sampling clock of high speed AD through the output of multi rate - clock generator LMK03806 to realize the configurable sampling rate. The underlying hardware parameters of the system are encapsulated in the form of control word instructions which can be controlled in real time by serial , instructions issued by the upper computer. Finally the multi
