Description
(54). АНАЛИЗАТОР СПЕКТРА штаба 1 на гетеродин 6, Узкополосный фильтр 7, подключенный к смесителю 5, вы вл ет узкий участок спектра со срелней час- |тотой, равной промежуточной частоте тракта Формула иаобрвтени Анализатор спектра, содержащий преобразователь временного масштаба, выход кото рого соединен со входом перестраиваемого гетеродина, подключенного через смеситель 24 к узкополосному 4 льтру, и со входом сче1 чика реализаций, выход которого соединен со входом блока пам гги, о т л ч а joш к и с тем, что, с целью псжышепи точности анализа штскретных частот, он снабжен фазовращателем с цифровым управле нием, причем, сигнальный вход фазоврашател соединен с выходом прео6рааовател . временного масштаба, упра вл юший вход фазовращател присоединен к выходу блока пам ти, авыход фазовращател : соединен со втсфым входом смесител .(54). SPECTRUM ANALYZER of headquarters 1 for the local oscillator 6, Narrow-band filter 7 connected to mixer 5, reveals a narrow portion of the spectrum with a central frequency equal to the intermediate frequency of the path. tunable local oscillator connected via mixer 24 to narrowband 4 liters, and to the input of the implementation counter, the output of which is connected to the input of the memory block, so that, with the purpose of the PCS accuracy analysis At certain frequencies, it is equipped with a digital control phase shifter, moreover, the signal input of the phase grouser is connected to the output of the transducer. the time scale, the control input of the phase shifter is connected to the output of the memory unit, the output of the phase shifter: connected to the input of the mixer.
