Частотомеры HM8123 Подробнее
Немецкая компания Rohde & Schwarz основана в 1933 году в Германии, в г. Мюнхен учеными Физико-технического Университета Лотаром Роде и Германом Шварцем.
В нашей стране оборудование Rohde & Schwarz появилось в 1957 году. С тех пор, благодаря собственным технологиям и новаторским идеям сотрудников, Rohde & Schwarz становится одним из технологических лидеров для российских заказчиков различных государственных и силовых структур.
