PURPOSE: A sub-channel analysis method in a distribution system and an apparatus using the same are provided to reduce network consumption by an analysis middle value transmitted to a main terminal and to prevent a memory lack in the main terminal, thereby processing a longer waveform. CONSTITUTION: A main terminal(100) includes an analysis target waveform database(102), an analysis task assigning unit(104), and an analysis result collecting unit(106). The analysis target waveform database stores analysis target waveform information. The analysis task assigning unit recognizes the number of sub terminals, divides the number of the sub terminals with the number of candidate keys and delivers the candidate keys to each of the sub terminals. The analysis result collecting unit receives or collects a result waveform of which analysis is completed by the sub terminals. The sub terminals include analysis target waveform database(202), and an analysis task operating unit(204). The analysis target waveform database stores the analysis target waveform information supplied from the main terminal in advance, and corresponding analysis target waveform information is selected by the analysis task operating unit as necessary. The analysis task operating unit analyzes a corresponding analysis target waveform based on the candidate keys supplied from the analysis task assigning unit of the main terminal.
