Several charities are or were associated with Tektronix, including the Tektronix Foundation and the M.J. Murdock Charitable Trust in Vancouver, Washington.
In 1956 a large piece of property in nearby Beaverton became available with the closing of the Bernard Airport, and the company’s employee retirement trust purchased the land and leased it back to the company. Construction began in 1957 and on May 1,1959 Tektronix moved into its new Beaverton headquarters campus. Its IPO, when it publicly sold its first shares of stock, was on September 11, 1963. In 1974 the company acquired in Wilsonville, Oregon where they built a facility for their imaging group. By 1976 the company employed nearly 10,000, and was the state’s largest employer.
For many years, Tektronix was the major electronics manufacturer in Oregon, and in 1981 U.S. payroll peaked at over 24,000 employees. Tektronix also had operations in Europe, South America and Asia. European factories were located in St. Peter Port on the island of Guernsey (then in the European Free Trade Association), Hoddesdon (North London, UK) and Heerenveen, The Netherlands (then in the European Common Market).
For many years, Tektronix operated in Japan as Sony-Tektronix, a 50-50 joint venture of Sony Corporation and Tektronix, Inc; this was due to Japanese trade restrictions at the time. Since then, Tektronix has bought out Sony's share and is now the sole owner of the Japanese operation.
Some former Tektronix employees left to create other successful Silicon Forest companies. Spin-offs include Mentor Graphics, Planar Systems, Floating Point Systems, Merix Corporation, and Anthro Corporation. Even some of the spin-offs have created spin-offs, such as InFocus. Tektronix instruments have enjoyed a leading position in the test and measurement market for decades, basically beginning with the firm's first cathode ray oscilloscopes. Much like Hewlett-Packard, Tektronix had a company policy of designing equipment of the very highest quality. Their equipment was quite expensive, but usually unmatched in performance, quality, and stability. Most test equipment manufacturers built their oscilloscopes with off-the-shelf, generally available components. But Tektronix, in order to get an extra measure of performance, used many custom-designed or specially-selected components. They even had their own factory for making ultra-bright and sharp CRT tubes. Later on they built their own integrated circuit manufacturing facility in order to make ICs of their own design with many times the performance of generally available components.
Tektronix instruments contributed significantly to the development of computers and communications equipment and to the advancement of research and development in the high-technology electronics industry generally.
On November 21,2007, Tektronix was acquired by Danaher Corporation for $2.85 billion. Prior to the acquisition, Tektronix traded on the New York Stock Exchange under the symbol TEK, the nickname by which Tektronix is known to its employees, customers, and neighbors. On October 15,2007, Danaher Corporation tendered an offer to acquire Tektronix for $38 cash a share, which equated to a valuation of approximately $2.8 billion. The deal closed five and a half weeks later, with 90 percent of TEK shares being sold in the tender offer. Also, as part of its acquisition by Danaher, the Communications Business division of Tektronix was spun off into a separate business entity under Danaher, Tektronix Communications.
