Изобретение относитс к радиоэлектронике, может быть использовано при контроле температуры кварцевых резонаторов автогенераторов стабильной частоты.The invention relates to electronics, can be used to control the temperature of quartz resonators of oscillators of stable frequency.
Известен способ контрол температуры кварцевого резонатора, возбуждаемого одновременно на рабочей стабильной частоте какого-либо побочного колебани .A known method of controlling the temperature of a quartz resonator excited simultaneously at the working stable frequency of any side oscillation.
Однако одновременна генераци двух независимых частот обусловливает нежелательный режим работы кварцевого резонатора и затрудн ет получение спектрально чистого сигнала основного колебани .However, the simultaneous generation of two independent frequencies causes an undesirable mode of operation of the quartz resonator and makes it difficult to obtain a spectrally pure fundamental oscillation signal.
Цель изобретени - упрощение процесса контрол .The purpose of the invention is to simplify the control process.
Предлагаемым способом температуру контролируют по измепепию амплитуды гармоники основного колебани при нарушении кратности ее частоты с частотой побочного колебани .By the proposed method, the temperature is controlled by measuring the amplitude of the harmonic of the main oscillation in violation of the frequency of its frequency with the frequency of the side oscillation.
Нелинейность элементов автогенератора при возбуждении кварцевого резонатора на частоте основного колебани обусловливаетThe nonlinearity of the elements of the oscillator when the quartz resonator is excited at the frequency of the fundamental oscillation causes
присутствие гармоник этой частоты на электродах резонатора. В момент совпадени резонансной частоты побочного колебани с одной из гармоник сопротивление резонатора па частоте чтой гар1 гоники резко мен етс , соответственно мен етс ее амплитуда.the presence of harmonics of this frequency on the electrodes of the resonator. At the moment of coincidence of the resonant frequency of the side oscillation with one of the harmonics, the resistance of the resonator at the frequency of the harmonic changes sharply, its amplitude changes accordingly.
Предлагаемый способ контрол применим дл кварцевых резонаторов, у которых частота побочного колебани при рабочей температуре кратна частоте основного колебани , что может быть достигнуто выбором геометрической формы и угла среза пьезоэлемента.The proposed control method is applicable to quartz resonators, in which the frequency of side oscillations at operating temperature is a multiple of the frequency of the main oscillation, which can be achieved by choosing the geometric shape and cut-off angle of the piezoelectric element.
