ことを特徴とするＦＭ信号発生器。In an FM signal generator comprising a voltage controlled oscillator that is phase-locked to a frequency-modulated reference signal source, the reference signal source includes a first reference signal source with a small frequency deviation width and a first reference signal source with a large frequency deviation width. It is composed of a second reference signal source and a switching means that selects and outputs either the first or second reference signal source, and when the frequency deviation width is small, the second reference signal source has a high frequency stability. An FM signal generator characterized in that one reference signal source can be used.
