Рассмотрена задача оценки ложных приёмки и браковки – рисков, возникающих при климатических испытаниях радиоэлектронной аппаратуры. Показано, что на увеличение указанных рисков влияет дополнительное рассогласование передающих линий радиоэлектронной аппаратуры, обусловленное температурными неоднородностями. Предложена методика подбора защитной полосы для минимизации вероятности ложной приёмки и отбраковки испытываемых устройств. Полученные результаты позволяют определять оптимальный коэффициент защитной полосы измерения для минимизации рисков потребителя и производителя радиоэлектронной аппаратуры.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this study is to create a methodology for assessing the risks arising from climatic tests of radio-electronic equipment. The article considers the effect of additional misalignment of transmission lines arising under conditions of temperature inhomogeneities on the increase in consumer and producer risks. A method of selecting a protective measuring band is proposed to minimize the probability of false acceptance and rejection of the tested devices. The results obtained make it possible to determine the optimal, from the point of view of the risks of the consumer and the manufacturer, the coefficient of the protective band of radio engineering measurement.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рассогласование передающих линий</kwd><kwd>температурные неоднородности</kwd><kwd>защитная полоса</kwd><kwd>риски</kwd></kwd-group><kwd-group xml:lang="en"><kwd>transmission lines mismatch</kwd><kwd>temperature inhomogeneities</kwd><kwd>guard band</kwd><kwd>risks</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Forbes A.
