Description
содержит электронно-лучевой индикатор и устройства развертки электронного луча. .contains an electron-beam indicator and an electron-beam sweep device. .
Описываемое устройство работает следующим образом.The described device operates as follows.
С помощью приемо-излучагощего элемента 12 производитс облучение контролируемого объекта 16 колебани ми, промодулированными по частоте. IUsing the transceiver element 12, the controlled object is irradiated with 16 oscillations modulated in frequency. I
Дл образовани таких колебаний используютс треугольные модулирующие импульсы , поступающие на генератор 2 с генератора / треугольных импульсов. С помощью коммутатора 3 колебани подаютс на усилительTo form such oscillations, triangular modulating pulses are applied to generator 2 from generator / triangular pulses. Using switch 3, the oscillations are fed to the amplifier.
4мощности только во врем формировани одного из фронтов модулирующих импульсов, например, заднего, а на врем формировани второго немодулирующего фронта треугольных импульсов комментатор 3 отключает усилитель 4 от генератора 2. Така коммутаци устран ет вли ние переходных процессов на точность измерени . С усилител 4 мощности колебани подаютс на управл емый вариометр 5, на управл емую обмотку которого поступают треугольные модулирующие импульсы с генератора /.4, during the formation of the second non-modulating front of triangular pulses, commentator 3 disconnects amplifier 4 from oscillator 2. Such switching eliminates the influence of transients on the measurement accuracy. From the amplifier 4, the power is oscillated to the controlled variometer 5, to the controlled winding of which triangular modulating pulses are received from the generator /.
Таким образом, управл емый вариометрThus, controlled variometer
5позвол ет расширить полосу пропзскани частот приемо-излучающего элемента, увеличить разрещающую способность измерений и повысить чувствительность устройства.5 allows expanding the frequency band of the receiving-radiating element, increasing the measurement resolution and increasing the sensitivity of the device.
