Description
Иззестен способ измерени крутизны анодко-сеточкой характеристики электронных ламп, осуществл емый методом измерени переменной составл ющей в цепи анода , всзнакающей за счет введени внешнего переменного напр жени в цепь первой сетки лампы. Источником переменного напр жени служит обычно ламповый rcH.ej aтор или цепь переменного тока.The method of measuring the anode-grid steepness of the characteristics of the electron tubes is carried out by measuring the variable component in the anode circuit, which is due to the introduction of an external alternating voltage in the circuit of the first grid of the lamp. The source of alternating voltage is usually the lamp rcH.ej ator or alternating current circuit.
Нар ду с этим способом примен етс так называемый «метод двух точек, не требующий источника переменного напр женки, но дающий большие погрешности измерени .Along with this method, the so-called "two-point method" is used, which does not require a source of alternating voltage, but gives large measurement errors.
Недостатками существующих методов вл ютс необходимость применени внешнего источника переменного напр жени и большие погрещнссти измерени .The disadvantages of the existing methods are the need to use an external source of alternating voltage and large measurement bounds.
Описываемое изобретение устран ет указанные недостатки.The described invention eliminates the indicated disadvantages.
Предметом насто щего изобретени вл етс способ измерени анодно-сеточной характеристики без применени внешнего Источника переменного напр жени , прдараемого на управл ющую сетку испытуемой ланпы.The object of the present invention is a method of measuring an anodic grid characteristics without using an external AC voltage source applied to a control grid of a tested lanpa.
Особенностью изобретени вл етс применение градуированного четырехполюсника обратной св зи.A feature of the invention is the use of a graded quadrupole feedback.
На чертеже представлена схема дл измерени крутизны лампы (в качестве примера дл триода), в которой переменное напр жение дл первой сетки обеспечиваетс caMof испытуемой лампой, так как схема представл ет обычный RC-генератор .The drawing shows a circuit for measuring the slope of a lamp (as an example for a triode), in which the alternating voltage for the first grid is provided by caMof the lamp under test, since the circuit represents a conventional RC generator.
Работа схемы основана на следующем принципе. Если величина крутизны превосходит определенный предел, завис щий от соотношени The operation of the scheme is based on the following principle. If the value of the slope exceeds a certain limit, depending on the ratio
, то схема генерирует; при then the circuit generates; at
R R
меньшей величине крутизны генераци отсутствует. Индикатор, указывающий наличие генерации, свидетельствует о годности или негодности испытуемой лампы по величине крутизны анодно-сеточной характеристики.a smaller value of the generation slope is absent. The indicator indicating the presence of generation indicates the suitability or unsuitability of the test lamp by the magnitude of the anodic grid characteristic.
