Ультразвуковой генератор/предусилитель 5077PR

Ультразвуковой генератор/предусилитель 5077PR с ручным управлением: полоса пропускания 35 МГц (–3 дБ) и генератор прямоугольных импульсов идеально подходят для улучшения характеристик принимаемого сигнала в материалах с высоким рассеянием звука. Генератор прямоугольных импульсов особенно эффективен при выполнении контроля с использованием преобразователей до 10 МГц.
