PROBLEM TO BE SOLVED: To realize a bus analyzer with high reliability that can prevent missing of captured data by detecting occurrence of a bus reset storm. SOLUTION: The bus analyzer that captures packet data communicated through a bus so as to measure and analyze a state of the bus, includes a counter that counts the number of bus reset signals communicated through the bus, a timer that controls a count time of this counter, and a discrimination section that discriminated the occurrence of the bus reset storm when the count of the counter reaches a prescribed value.
