Description
Таким образом, осуществл етс пр мой и обратный поиск частоты. Если при этом фаза сигнала ошибки такова, что в цепи автоподстройки обратна св зь отрицательна, то происходит захват частоты.Thus, a forward and reverse frequency search is performed. If, in this case, the phase of the error signal is such that the feedback in the auto-tuning circuit is negative, then frequency acquisition occurs.
Настройка гетеродина осуществл етс либо на частоту FC , либо на частоту FC - Лгу.The tuning of the local oscillator is carried out either on the FC frequency, or on the FC frequency - Lg.
Если зона электроиной настройки клистрониого гетеродина Д fa 2/пр, то допустимый диапазон изменени частоты входного сигналаIf the area of the electron is the setting of the klystrony heterodyne D fa 2 / pr, then the permissible range of variation of the frequency of the input signal
+ 2Fnp-Af,. + 2Fnp-Af ,.
Если известные устройства автоподстройки частоты клистронного гетеродина имеют допустимый диапазон изменени частоты входного сигнала, равный , то при использоваНИИ предлагаемого устройства он увеличиваетс на величину 2fnp.If the known devices for controlling the klystron heterodyne oscillator frequency have the allowable frequency range of the input signal equal to, then when using the device of the proposed device it is increased by 2fnp.
