Ca. 20.000 Beschäftigte in der 70er Jahren; Angemeldete Patente bis zum Jahre 2005: 675. Tektronix ist vor allem für seine elektronischen Test- und Ausrüstungsgegenstände wie Oszilloskope, Logikanalysatoren sowie Video und mobile Testprotokollausrüstungen bekannt. Am 15. Oktober 2007 gab das Unternehmen bekannt, vom US Grosskonzern Danaher für 2,8 Milliarden Dollar übernommen worden zu sein. Established in 1946 by Howard Vollum and Jack Murdock;
Production start 1947; 1960 largest manufacturer in Oregon; 20,000 employees in the 1970´s; 675 patents registered until 2005. Abstract from Wikipedia: The company traces its roots to the electronics revolution that immediately followed World War II. The company's founders C. Howard Vollum and Melvin J. "Jack" Murdock invented the world's first triggered oscilloscope in 1946, a significant technological breakthrough. Tektronix was then incorporated in 1946 with its headquarters at SE Foster Road and SE 59th Street in Portland, Oregon. In 1947 there were 12 employees, and 250 in 1951. By 1950 the company began building a manufacturing facility in Washington County, Oregon at Barnes Road and the Sunset Highway and expanded the facility by 1956 to 80,000 square feet (7,000 m²). The company then moved its headquarters to this site following an employee vote. Also 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 on this current campus began in 1957 and on May 1, 1959 Tektronix moved into its new Beaverton headquarters. Its IPO, when it publicly sold its first shares of stock, was on September 11, 1963. In 1974 the company acquired 256 acres (1.0 km²) 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 spin-off companies, including 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. A Tektronix model 475A portable analog oscilloscope, a very typical instrument of the late 1970s. 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 USD. 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 $38.00 a share in cash, 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. |

Sony/Tektronix, a jointly-owned Japanese subsidiary located in Tokyo, Japan, was formed in November of 1964. The rapid growth of the Japanese electronics industry in the early 60's resulted in licensing discussions with several Japanese firms. The result of diese discussions led to the formation of a 50-50 joint venture with SONY. Both SONY and Tektronix have cross-licensing arrangements with Sony/Tektronix. |

We have experienced a tremendous response to our announcement in the February, 1966, issue of SERVICE SCOPE on the availability of Tektronix-produced films. The requests by our readers for the use of these films have exceeded our wildest expectations and sorely taxed our ability to promptly supply the films. We are filling all requests on a first-come, first-served basis and earnestly solicit your patience and understanding if we fail to supply the wanted film promptly. All requests from qualified sources will be honored; hut, there may be a delay of several weeks in supplying some of the more popular films.
A new Tektronix-produced film is now available to schools or to companies engaged in educational or training programs for their employees. This film like the previously announced ones may be obtained on a free loan basis, or may he purchased. Title of the new filmis TransresistanceIt is a lecture-type film that offers an explanation of the transresistance method of analyzing transistorized circuitry. (An article in the December, 1964, issue of SERVICE SCOPE, "Simplifying Transistor Linear Amplifier Analysis" discussed transresistance as an aid in troubleshooting or evaluating transistor circuits.) Audiences for this film should have a sound basic knowledge of transistor theory and terminology. People interested in showing these films should contact their local Tektronix Field Office, Field Engineer, Field Representative, or Distributor. Source: SERVICE SCOPE Jun 1966 |
