Description

Дл  автоматического определени  ошибки сопр жени  настроек входного контура и контура гетеродина супергетеродинного приемника в отдельном смесителе смешиваютс  сигналы от гетеродина приемника и вспомогательного ЧМ генератора и на вход приемника подаетс  напр жение комбинационной частоты, а на выходе амплитудного детектора приемника выдел етс  при помощи фильтра перва  гармоника напр жени , модулирующего ЧМ генератор, котора  затем -подаетс  на управл ющую обмотку двухфазного асинхронного двигател , вращающего ротор конденсатора переменной емкости в контуре ЧМ генератора, в результате чего производитс  подстройка средней частоты ЧМ генератора на максимальное значение резонансной кривой входного контура. Величина и знак ошибки сопр жени  настроек в данной точке диапазона определ ютс  по указателю, св занному с ротором конденсатора переменной емкости в контуре ЧМ генератора. При непрерывном повороте ручки настройки приемника прибор выдает кривую ошибки сопр жени .In order to automatically determine the coupling error of the input circuit and the heterodyne loop of the superheterodyne receiver, signals from the heterodyne of the receiver and the auxiliary FM generator are mixed in a separate mixer, the combination voltage is applied to the receiver input, and the output of the amplitude detector of the receiver is extracted using the first harmonic modulating FM generator, which is then fed to the control winding of a two-phase asynchronous motor that rotates the condenser a variable capacitance circuit in the FM oscillator, whereby adjustment is performed average FM oscillator frequency to the maximum value of the resonance curve of the input circuit. The magnitude and sign of the adjustment error at a given point in the range is determined by the pointer associated with the variable capacitor rotor in the FM generator circuit. If you turn the receiver tuning knob continuously, the device produces a mating error curve.

Способ определени  ошибки сопр жени  входного контура и контура гетеродина супергетеродинного приемника, отл и ч а ю щи и с   тем, что, с целью автоматической выдачи кривой ошибки сопр жени , смешивают сигналы от вспомогательного частотно-модулированного генератора и гетеродина приемника и напр жение комбинационной частоты подают на вход приемника, с выхода амплитудного детектора которого выдел ют фильтром первую гармонику напр жени  с частотой модул ци, управл   реактивным элементом, производ т подстройку средней частоты генератора частотно-модулированного сигнала на максимальное значение резонансной кривой входного контура, одновременно напр жение с выхода фильтра используют дл  индикации ошибки сопр жени .The method of determining the coupling error of the input circuit and the heterodyne oscillator circuit of the superheterodyne receiver, is excellent, so that, in order to automatically output the coupling error curve, the signals from the auxiliary frequency-modulated oscillator and the oscillator of the receiver and the voltage of the combination frequency are mixed is fed to the input of the receiver, from the output of the amplitude detector of which the filter separates the first harmonic voltage with the modulation frequency, controls the reactive element, adjusts the average frequency of the generator the torus of the frequency-modulated signal to the maximum value of the resonant curve of the input circuit, while simultaneously the voltage from the filter output is used to indicate the coupling error.
