Description

Известны коаксиальные бесщелевые измерительные линии, в которых элемент св зи с генератором неподвижен, а элемент св зи с индикатором подвижен и перемещаетс  вместе с короткозамыкателем.Coaxial gapless measuring lines are known in which the communication element with the generator is stationary, and the communication element with the indicator is mobile and moves together with the short circuit breaker.

В описываемом изобретении элемент св зи линии с индикатором установлен неподвижно, что увеличивает точность измерений и позвол ет измер ть не КСВН нагрузок, а их полную проводимость.In the described invention, the communication element of the line with the indicator is fixedly mounted, which increases the measurement accuracy and makes it possible to measure not the VSWR of the loads, but their total conductivity.

При этом дл  измерени  реактивной составл ющей проводимости не требуетс  дополнительного измерени  с подключенным вместо нагрузки фиксированным короткозамыкателем. Точность измерений увеличиваетс  в 2-3 раза по сравнению с точностью обычных измерительны.х линий..At the same time, to measure the reactive component of the conductivity, no additional measurement is required with a fixed short-circuit switch connected instead of the load. The measurement accuracy is increased by a factor of 2-3 compared with the accuracy of conventional measuring lines.

Измерительный генератор J (см. блок-схему) и индикатор 2 через коаксиальные тройники 3 св заны с коаксиальной бесщелевой измерительной линией посредством идентичных двойных зондов. Перемещение короткозамыкател  контактного типа 4 производитс  поворотом маховика , св занного с т гой короткозамыкател  посредством зубчато-реечной передачи 5. Отсчет положени  производитс  по линейке б.The measuring generator J (see block diagram) and indicator 2 are connected via coaxial tees 3 to a coaxial gapless measuring line by means of identical double probes. The contact-type short-circuit is moved by turning the flywheel associated with the short-circuit by means of a rack-and-pinion gear 5. The position is calculated according to the ruler b.

При измерени х узлы и пучности сто чей БОЛНЫ перемещаютс  вместе с короткозамыкателем относительно неподвижного индикаторного зонда 7. Вследствие реакции со стороны нагрузки уровень сто чей волны измен етс  при перемещении короткозамыкател  вдоль линии и индицируетс  распределение сто че) волны переменного уровн , поэтому получаема  крива  показаний асимметрична и имеет нулево Minniмум .During the measurements, the nodes and the antinodes of the standing PATIENTS move together with the shorter relative to the fixed indicator probe 7. Due to the response from the load, the level of the standing wave changes as the short shuffler moves along the line and the distribution of the alternating level wave is displayed, therefore, the reading curve is asymmetric and has zero Minnium.

Нулевой минимум получаетс , когда узел сто чей волны проходит через сечение, где расположен индикаторный зонд 7. По асимметрии кривой определ етс  реактивна  составл юща  полной проводимости нагрузки.The zero minimum is obtained when the node of the standing wave passes through the section where the indicator probe 7 is located. From the asymmetry of the curve, the reactive component of the total load conductance is determined.

Описанное устройство примен етс  дл  аттестации высокочастотных нагрузок.The described device is used to certify high frequency loads.
