MODULATION SIGNAL ANALYSIS APPARATUS

摘要

PROBLEM TO BE SOLVED: To efficiently implement analysis of a signal included in a modulation signal being a measuring object and of a channel of a communication system designated by an operator by decreasing useless measurements to the utmost extent.

SOLUTION: Each channel number and each frequency corresponding thereto designated externally and belonging to the communication system are read from a communication system channel memory 1 and written in a measuring list table 9. A signal value of the frequency component of each frequency stored in the measuring list table is measured as a power value of a corresponding channel number and whether or not the power value is a threshold value or over is written in a power judgement result table 9. Then the modulation system of each channel number whose power value is judged to be the threshold value or over is judged and a result of judgement the modulation system of each channel is written in a modulation analysis result table 22.
