PURPOSE: A digital auto-correlation spectroscope is provided to achieve improved sensitivity, while allowing for an observation for the high frequency wide band signal. CONSTITUTION: A digital auto-correlation spectroscope comprises an intermediate frequency to baseband converting unit(100) for converting a high frequency wideband signal into a baseband signal; a correlator unit(200) for converting an input signal into a digital signal, converting the digital signal into three-level data within the observed bandwidth, and obtaining an auto-correlation coefficient; a correlation control system(400) for inputting/outputting control signals for controlling the correlator unit and the intermediate frequency to baseband converting unit, and outputting data; an interface unit(300) for interface of the correlator unit to the correlation control system; and a communication interface unit(500) for communication with an external system control computer for controlling the digital auto-correlation spectroscope.
