Description
Известно, что дл стабилизации частоты ламповых передатчиков с малым числом каскадов примен етс вление захватывани . При этом самовозбужденный ламповый генератор, вл ющийс обычно знающим дл последующих каскадов, синхронизируетс напр жением маломощного стабилизованного кварцем генератора.It is known that the capture phenomenon is used to stabilize the frequency of lamp transmitters with a small number of stages. In this case, the self-excited lamp generator, which is usually knowledgeable for subsequent stages, is synchronized by the voltage of a low-power quartz-stabilized generator.
При этом, как показывает опыт, вследствие обратного действи маломощных каскадов задающего генератора на кварц возможно, что генерируема энерги до частоте будет отличатьс от частоты автономного кварцевого генератора.In this case, as experience shows, due to the reverse action of low-power cascades of the master oscillator on quartz, it is possible that the generated energy will differ from the frequency of the autonomous quartz oscillator to the frequency.
Дл устранени этого влени пользуютс выбором частоты кварца такой, чтобы, после трансформации ее вверх, получить нужную частоту.To eliminate this phenomenon, one uses the choice of the frequency of quartz so that, after transforming it upwards, one obtains the desired frequency.
Однако, и в этом случае обратное воздействие задающегогенератора, хот и в сильно ослабленном виде, остаетс .However, in this case too, the reverse effect of the master oscillator, although in a greatly weakened form, remains.
Целью насто щего изобретени вл етс осуществление способа кварцевой стабилизации передатчика, в которомThe object of the present invention is to carry out a method of quartz stabilization of a transmitter, in which
(2зЬ)(2b)
используетс вление захватывани , дающего .возможность полностью освободитьс от обратного воздействи .the phenomenon of seizure is used, making it possible to completely free itself from the reverse effect.
Согласно изобретению это достигаетс путем использовани дл целей синхронизации одной из комбинационных частот, получаемых в результате гетеродинировани колебаний, генерируемых двум стабилизованными кварцем генераторами.According to the invention, this is achieved by using, for synchronization purposes, one of the combination frequencies obtained by heterodyning the oscillations generated by two quartz-stabilized oscillators.
Дл этой цели рекомендуетс использование комбинационных частот вида 1 + 2; 2%-f« 2; + Зв 1-|-2о)а; 2 в)-|-3 coj и т. д., так как это дает возожность синхронизировать сразу генератор , частота которого много выше, чем частота каждого из кварцев, обход сь без промежуточной трансформации частоты вверх.For this purpose, the use of combinational frequencies of the 1 + 2 type is recommended; 2% -f "2; + Sv 1- | -2o) a; 2 c) - | -3 coj, etc., since this makes it possible to synchronize immediately the generator, whose frequency is much higher than the frequency of each of the quartz, bypassing the intermediate frequency transformation upwards.
Легко видеть, что при таком способе обратное воздействие на кварцы может ыть полностью ycTpatjCHO выбором кварцев, частоты которых не наход тс в каких-лиЪо соотношени х с генериуемой частотой.It is easy to see that with this method the reverse effect on quartz can be completely ycTpatjCHO by the choice of quartz, whose frequencies are not in any ratios with the generated frequency.
