Abstract
An FM modulator measuring an f-V characteristic of a voltage controlled oscillator in a reduced time period. In the FM modular a characteristic measurement time control sectionnotifies a correction sectionof a time at which a measurement of the f-V characteristic of a voltage controlled oscillatoris to start and a time at which the measurement of the f-V characteristic of the voltage controlled oscillatoris to and while a carrier wave frequency is being changed to a predetermined frequency. Thus, the correction sectionmeasures the f-V characteristic of the voltage controlled oscillatorin a reduced time period.
