(54) СПОСОБ КАЛИБРОВКИ ВАТТМЕТРА ПРОХОДЯЩЕЙ МаЦНОСТИ НА мостовом 1-1АПРАВЛЕННОМ(54) METHOD OF CALIBRATION OF THE WATTMETER OF PASSING MATTERNESS ON THE BRIDGE 1-1 DIRECTED
ОТВЕТВИТЕ.11Е Повышение чувствительности позвол ет первоначальное показание Vu индикатора калибруемого ваттметра получить при значительно меньших значени х мощности генератора, уровень которой фиксируетс в относительных единицах А, с помощью измери тел ослаблени , например установок типа Д1-3, ДК1-5, Д1-9 и т.д. В дальнейшем выходна мощность ге нератора дискретно увеличиваетс , и каждому показанию Vj индикатора калибруемого ваттметра и показанию А j измерител ослаблени соответствует реальна мощность в линии передачи Р|, определ ема па формуле Р. ig Формула изобретени Способ калибровки ваттметра про1ход щей мощности на мостовом направленном ответвителе, основанный на сравнении показаний калибруемого и образцового ваттметров, отличающийс тем, что, с целью уменьшени потребл емой мощности, сравнение показаний калибруемого и образцового ваттметров производ т на уровне мощности, соответствующем начёшьному участку динамического диапазона калибруемого ваттметра, затем увеличивают чувствительность калибруемого ваттметра путем разбалансировки мостового направленного ответвител и, ввод т калиброванное затухание , осуществл ют калибровку ваттжтра . Источники информации, прин тые во внимание при экспертизе 1. Вилько М. И. и др. Измерение мощности на СВЧ. М.,,Сов. радио, 1976, с. 133 (прототип).RESPONSE.11E Increasing the sensitivity allows the initial reading Vu of the calibrated wattmeter indicator to be obtained at much lower values of the generator power, the level of which is recorded in relative units A, by measuring attenuation bodies, such as D1-3, DK1-5, D1-9 installations etc. Subsequently, the output power of the generator is discretely increased, and each readout Vj of the indicator of the wattmeter being calibrated and readout Aj of the attenuation meter corresponds to the actual power in the transmission line P | defined by formula P. ig Invention Form based on comparison of indications of calibrated and exemplary wattmeters, characterized in that, in order to reduce power consumption, comparison of indications of calibrated and exemplary of wattmeters produced on a power level corresponding to the portion of the dynamic range nachoshnomu calibrated power meter, then increase the sensitivity being calibrated wattmeter by unbalancing the bridge directional coupler and calibrated introduced attenuation is performed vattzhtra calibration.
