SCM control through a special function of the signal chips, can produce a series of adjustable rate and frequency of the waveform. Such a signal device in the field of control of a wide scope of application. Because the series of adjustable waveform can be used as some other equipment of the numerical input. Also can be used in testing equipment, apparatus, debugging and other occasions. High-frequency stability of the signals can also be used for FM radio waves, in the demodulator.
