Description
На чертеже изображена блок-схема радиоспектрометра .The drawing shows a block diagram of a radio spectrometer.
Источник радиочастотного пол (РЧ) состоит из двух генераторов 1 и 2, подключенных к сумматору 3. Сумматор 3 нагружен на градуированный аттенюатор 4 и СВЧ-тракт, включающий направленный ответвитель 5, анализатор спектра 6 и измеритель проход щей мощности 7, двойной волноводный тройник 8, к которому присоединены аттенюатор 9 с короткозамыкающим поршнем 10, индикатор // п через согласующее устройство 12 - измерительный резонатор с приемной катушкой 13. Приёмна катушка 13 соединена с приемником 14, к которому подключен индикаторный прибор 15. СВЧ-колебани от генераторов 1 н 2 поступают на сумматор 3, а затем через аттенюатор 4, с помощью которого устанавливаетс необходимый дл экснеримепта уровень мощности пол , и направленный ответвитель 5 с калиброванным ослаблением проход т на анализатор спектра 6 и измеритель проход щей мощности 7.The radiofrequency field (RF) source consists of two generators 1 and 2 connected to adder 3. Adder 3 is loaded on a graduated attenuator 4 and a microwave path, including a directional coupler 5, a spectrum analyzer 6 and a passing power meter 7, a double waveguide tee 8 To which an attenuator 9 with a short-closing piston 10 is connected, an indicator // n through a matching device 12 - a measuring resonator with a receiving coil 13. The receiving coil 13 is connected to a receiver 14 to which the indicator device 15 is connected. Microwave Fucks from generators 1 n 2 are fed to adder 3, and then through attenuator 4, by means of which the field level required for the excavator is set, and directional coupler 5 with calibrated attenuation is passed to spectrum analyzer 6 and passing power meter 7.
Основна часть сигнала через тройник 8 в системе согласовани , состо щей из аттенюатора Я короткозамыкающего порщи 10, индикатора 11 и согласующего устройства 12, поступает на измерительный резонатор, в котором расположены приемна катущка и исследуемое вещество. Сигнал с приемной катушки поступает на приемник 14, настроенный на частоту Q, равную (кратную) разности частот генераторов 1 и 2 с индикаторным прибором 15.The main part of the signal through the tee 8 in the matching system, consisting of the attenuator I shorting pores 10, the indicator 11 and the matching device 12, enters the measuring resonator, in which the receiving coil and the test substance are located. The signal from the receiving coil is fed to the receiver 14, tuned to a frequency Q equal to (multiple) the difference between the frequencies of the generators 1 and 2 with the indicator device 15.
В процессе эксперимента исследуетс зависимость наблюдаемой на индикаторном приборе 15 величины сигнала от величины относительной расстройки генераторов / и 2.In the course of the experiment, the dependence of the magnitude of the signal observed on the indicator device 15 on the value of the relative detuning of the generators / and 2 is investigated.
