75 years of innovation: The very first instrument

May 09, 2008 - 75 years Rohde & Schwarz is 75 years of test and measurement, radiocommunications, and broadcasting technology. Delve into the historical highlights of the company and its innovative technology.

Even before founding the company, Dr. Lothar Rohde and Dr. Hermann Schwarz developed their first measuring instrument for Hermsdorf-Schomburg-Isolatoren-Gesellschaft (Hescho). The young engineers had received reports about new ceramic materials that exhibited very low dielectric losses at high frequencies. But a number of national and international institutes commissioned by Hescho had all come up with different dissipation factors. Rohde and Schwarz immediately embarked on developing a test setup that in no time at all was able to produce highly accurate results. It was an interference wavemeter with a wide range (6 m to 3600 m wavelength), and at the same time the first measuring instrument for RF ceramic compontent.
