Abstract

This paper describes the system configuration and the some results of the prototype wide-band digital autocorrelation spectrometer for radio astronomy observation, which will be used as back-end spectrometer for the 2/3mm dual channels SIS receiver at Taeduk Radio Astronomy Observatory. This spectrometer consists of high-speed sampler module, circular memory buffer module, and correlator module based on QUAINT correlator chip. The developed digital autocorrelator shows good performance results at 50MHz and 100MHz mode with the 10MHz CW source input. After some calibration procedure, this spectrometer can be use as back-end system at TRAO
