Apparatus for measuring signal quality

PURPOSE: An apparatus for measuring signal quality of a wireless communication signal are provided to receive a wireless communication signal on the air and store by separating an effectiveness data and RF data and compare/analyze the effectiveness/RF data thereby analyze a dynamic signal comprehensively. CONSTITUTION: A signal receiving part(101) selectively receives a wireless communication signal on the air. An effectiveness data storage part(105) stores the effectiveness data of the wireless communication signal. A RF(Radio Frequency) data storage module(107) stores a RF data for transmission of the effectiveness data. A signal processing unit(109) demodulates the received wireless communication signal, extracts the effectiveness data, store in the effectiveness data storage part, and store the RF data in the RF data storage part. An identifying information allocation(111) assigns the same id to the effectiveness data and the RF data. A control part(113) analyzes the demodulated effectiveness data and measures/provides a signal quality using by an analysis result.
