Изобретение относитс  к области электроизмерительной техники, в частности к о6 ласти измерени  параметров туннельных диодов.The invention relates to the field of electrical measuring equipment, in particular, to the field of measuring parameters of tunnel diodes.

Известны устройства дл  измерени  напр йсени  пика и впадины и токов соответствующих им на вольтамперной характеристике туннельного диода, содержащие источник измен ющегос  напр жени , подаваемого на испытуемый туннельный диод, блок регистрации импульсов, блок управлени  и регистрируюйша приборы ij. При этом значени  интересующих параметров определ ютс  в момент перепада напр жени  по достижении напр жений впадины и пика вольтамперной характеристики туннельного диода, после чего вс  схема затормаживаетс . Недостатком данного устройства  вл етс  необходимость наличи  быстродействующего управл емого источника измен ющегос  напр жени .Devices are known for measuring the peak and trough voltage and the currents corresponding to them on the volt-ampere characteristic of a tunnel diode, containing a source of varying voltage supplied to the tunnel diode under test, a pulse recorder, a control unit, and a recording instrument ij. In this case, the values of the parameters of interest are determined at the time of the voltage drop upon reaching the voltage of the depression and the peak of the current-voltage characteristic of the tunnel diode, after which the entire circuit is braked. The disadvantage of this device is the necessity of having a fast-acting controlled source of alternating voltage.

Известно устройство дл  измерени  характеристических токов и напр жений тун вльных диодов, содержащее генератор на исследуемом туннельном диоае, регистрируюшие приборы и цепи ск ещени  на туннельный диод. 27. Однако вследствие.сложности- определени  момента, предшествующего началу или срыву генерации туннельного диода, точность измерени  в большой степени зависит от индивидуальных свойств оператора и не превьпЕшет, как правило, 1%.A device for measuring characteristic currents and voltages of tunnel diodes is known, which contains a generator on the tunnel diode under test, registering devices and circuits from another diode to the tunnel. 27. However, due to the complexity of determining the moment preceding the onset or failure of the generation of a tunnel diode, the accuracy of measurement largely depends on the individual properties of the operator and does not exceed, as a rule, 1%.

Целью изобретени   вл етс  повышение точности измерени  путем автоматической регистрации момента возникновени  или срыва колебаний генератора.The aim of the invention is to improve the measurement accuracy by automatically recording the moment of occurrence or failure of oscillations of the generator.

Достигаетс  это тем, что введен управл емый генератор посто нного тока, выполненный в виде триггера, управл ющий вход которого соединен через усилитель с выходом генератора на туннельном диоде, а выход управл емого генератора посто нного тока соединен с цепью смещени  туннельного диода.This is achieved by introducing a controlled DC generator, made in the form of a trigger, the control input of which is connected through an amplifier to the generator output on a tunnel diode, and the output of a controlled DC generator is connected to a bias circuit of the tunnel diode.
