PROBLEM TO BE SOLVED: To provide a tracking analyzer which is improved in analysis accuracy based on rotational speed information acquired from a communication line for failure diagnosis provided in a vehicle compartment. SOLUTION: This tracking analyzer has: a vibration detection means 1 for detecting vibration generated from a measuring object; a buffer means 4 for storing vibration data outputted from the vibration detection means; a vibration data analysis means 5 for analyzing the vibration data stored in the buffer means; and a rotational speed signal output means 6 for outputting a rotational speed signal from the measuring object. The analyzer has a characteristic wherein an output from the buffer means is synchronized with the rotational speed of the measuring object by delaying a sampling timing relative to analysis processing of the vibration data stored in the buffer means corresponding to a conversion time of a conversion means.
