Data acquisition design of the RCS testing system

This paper introduces a method of data acquisition applied in the RCS testing system. The method in data acquisition, hardware configuration and working flow of the RCS testing system that working under the chirp signal condition are proposed. The design mainly adopts the data acquisition board, and FPGA supplies the trigger pulse of the acquisition board and the synchronization signal of the signal source device. The data acquisition parameter can be configured through the computer. Besides, the paper also introduces the function of the signal source Of HP, the DAQ2006 date acquisition device of the ADLINK Technology Inc used in this system, and the code of the parameter setting is presented. The testing result shows the design is up to the standard, and at last the sampling data, the RCS results and the experiment conclusion are presented in detail.
