In addition to its satellite products for the cable industry, Scientific-Atlanta manufactured testing and measuring devices for telecommunications, industrial, and laboratory use. The company added to its instrumentation operations when it acquired the San Diego-based Spectral Dynamics Corporation, a manufacturer of scientific devices, in 1978 for $17.4 million. Spectral Dynamics brought with it European sales subsidiaries in Germany, France, England, and the Netherlands. With these additions, Scientific-Atlanta had sales network that covered 40 countries and was supported by a worldwide service network that adjusted and repaired its instruments. Both Scientific-Atlanta and Spectral Dynamics relied on continual research and development to bring new products to market, thereby enhancing market share and fostering company growth.
