Abstract
This paper describes the design of five-element digital receiver system, which was developed to pretest and calibrate the Chinese Spectral Radioheliograph. By using the FPGA(Field Programmable Gate Array), the procedure of signal processing can be achieved very flexibly and easy. This can also be used for other astronomical observations. We will show the result of testing in the paper.
