Изобретение касаетс  измеритепьной техники дл  поверки фазометрической аппаратуры .The invention relates to a measuring technique for calibrating phase equipment.

Известны устройства дл  измерени  амплитудно-фазовой погрешности, в которых с помощью аттенюаторов измен ют уровень сигнала на одном из входов фазометра по отношению к уровню сигнала на другом входе . Изменение фазового сдвига, вносимого при изменении уровн  входного сигнала аттенюатором , исключают путем двукратного повторени  процесса при настройке гетеродина фазометра выше и ниже частоты входного сигнала 1.Devices for measuring amplitude-phase error are known, in which the signal level at one of the phase meter inputs is changed with respect to the signal level at the other input using attenuators. A change in the phase shift introduced when the input signal level is changed by an attenuator is eliminated by repeating the process twice when setting the local oscillator of the phase meter above and below the frequency of the input signal 1.

Недостатками данных устройств  вл етс  то, что они применимы татько к фазометрам с преобразованием частоты, у фазометров с автоматической подстройкой частоты гетеродина применение данного метода приводит к усложнению схемы фазометра дл  обеспечени  подстройки на промежуточную частоту при обоих положени х гетеродина и сохранени  значени  этой частоты одинаковой с высокой степенью точности в обоих случа х.The disadvantages of these devices are that they are applicable to phase-shifters with frequency conversion, for phase meters with automatic heterodyne frequency adjustment, the application of this method complicates the phase meter circuit to provide an adjustment to the intermediate frequency at both heterodyne positions and to keep the same frequency high degree of accuracy in both cases.

Известны устройства, ко которых подключен источник напр жени  переменного тока, к двум выходам повер емый фазометр и один или два регул тора напр жени , в качестве которого используютс  аттенюаторы Z.The devices to which the AC voltage source is connected are known, to two outputs a rotatable phase meter and one or two voltage regulators, for which Z attenuators are used.

Недостатком их  вл етс  ограниченный диапазон частот (не более долей и единиц мегаГерц).Their disadvantage is a limited frequency range (no more than fractions and units of megahertz).

Цель изобретени  - расширить диапазон частот.The purpose of the invention is to expand the frequency range.

Это достигаетс  тем. что устройство снабжено восьмиполюсником и двухполюсником, причем один из входов восьмиполюсника соединен с двухполюсником, другой - с генератором , а выходы его присоединены соответственно к первому и второму входам фазометра; восьмиполюсник выполнен в виде мостовой схемы, плечи которого образованы из первичной обмотки трансформатора зашу , . ированной последовательно соединенными первым и вторым резисторами, резистора , зашунтированного конденсатором, третьим и четвертым резисторами, причем к одному из выводов первичной обмотки трансThis is achieved by those. that the device is equipped with an eight-pole and two-pole network, with one of the inputs of the eight-port network being connected to a two-terminal network, the other with a generator, and its outputs are connected to the first and second inputs of the phase meter, respectively; the eight-pole is made in the form of a bridge circuit, the shoulders of which are formed from the primary winding of the transformer. connected in series by the first and second resistors, a resistor shunted by a capacitor, a third and fourth resistors, and one of the terminals of the primary winding is trans
