Overview
Tektronix is an American electronic test and measurement brand whose products are used by engineers, researchers, manufacturers, educators, and service organizations. Its core portfolio includes oscilloscopes, signal generators, spectrum analyzers, logic analyzers, digital multimeters, probes, software, and protocol-testing tools. The company is particularly associated with the development of high-performance oscilloscopes and with the spread of triggered-sweep, portable, plug-in, storage, and digital sampling technologies. The business traces its origins to the post-Second World War electronics industry. It was initially organized as Tekrad in late 1945, but the founders incorporated Tektronix in 1946 after discovering that a similar name was already in use. Physicist Howard Vollum developed the Model 511, generally recognized as the first commercially successful triggered oscilloscope. The instrument made it possible to obtain a stable display of repetitive electrical waveforms and established the technical direction of the company. Jack Murdock contributed business leadership and financing through his radio and appliance company, while Miles Tippery and Glenn McDowell were also part of the founding group. Tektronix expanded from a small Portland-area operation into one of Oregon's major technology companies. It moved its principal operations to a large Beaverton campus in 1959, and its growth helped stimulate the concentration of electronics and software companies later associated with Oregon's “Silicon Forest.” During the 1950s and 1960s, Tektronix introduced modular plug-in oscilloscopes, portable battery-capable instruments, high-frequency field oscilloscopes, and analog storage oscilloscopes. The company competed on performance, stability, engineering quality, and specialized components, including internally developed cathode-ray tubes and integrated circuits. In later decades the brand broadened beyond oscilloscopes into logic analysis, microprocessor development systems, signal generation, spectrum analysis, digital multimeters, and communications testing. It also operated internationally and participated in the Sony-Tektronix joint venture in Japan. The company's product and engineering ecosystem influenced many electronics businesses in the Pacific Northwest, including companies founded by former employees. Tektronix encountered structural and financial pressure in the 1980s as it operated across too many businesses and markets. It responded through layoffs, management changes, divestitures, and the separation of its printed-circuit-board manufacturing operation as Merix Corporation in 1994. Under chief executive Rick Wills, the company refocused on test and measurement. Danaher acquired Tektronix in 2007. Danaher's industrial businesses were later reorganized under Fortive, and Tektronix subsequently became part of Ralliant, a Fortive spinoff. The brand remains active in electronic test and measurement, serving semiconductor, embedded systems, aerospace and defense, automotive, communications, computing, education, and industrial customers.
History
Tektronix emerged from the rapid development of electronics after the Second World War. The company was first organized under the name Tekrad in December 1945. Because that name resembled an existing California business, Howard Vollum, Jack Murdock, Miles Tippery, and Glenn McDowell incorporated Tektronix in 1946. The founders each contributed an initial $2,600. Vollum, a physicist and former wartime electronics technician, supplied much of the early technical direction, while Murdock provided business experience through his radio and appliance enterprise. Vollum's principal early achievement was the triggered oscilloscope. Unlike earlier instruments that could produce unstable or difficult-to-read displays, a triggered sweep synchronized the display with the measured signal. Tektronix refined the design into the Model 511, manufactured from 1947, and built its early reputation around performance and precision. The company grew rapidly from 12 employees in 1947 to approximately 250 in 1951. It established a manufacturing site in Washington County, Oregon, and moved its headquarters to the Beaverton campus known as Tektronix Industrial Park in 1959. The company's product leadership expanded during the 1950s and 1960s. The 530 and 540 families popularized plug-in architectures that allowed users to adapt a main oscilloscope for different measurement tasks. Tektronix then introduced portable instruments, including the Model 321, high-frequency field oscilloscopes in the 400 series, and the Model 564, an important early mass-produced analog storage oscilloscope. These products helped make oscilloscopes useful outside conventional laboratories, including in military, field-service, manufacturing, and communications environments. During the 1970s, Tektronix maintained modularity while increasing instrument capability. The 5000 and 7000 series supported broad families of plug-ins, and some models reached exceptionally high bandwidth for their time. The company also produced custom cathode-ray tubes, integrated circuits, and other specialized components. Its activities expanded into logic analyzers, digital multimeters, signal generators, microprocessor development systems, and rack-mounted test equipment. International manufacturing and distribution operations were established in Europe, Asia, and South America. In Japan, the company operated for many years through a 50-50 Sony-Tektronix joint venture created in the context of Japanese trade restrictions. Tektronix's growth contributed to the development of Oregon's technology sector. Former employees helped establish or staff companies including Mentor Graphics, Planar Systems, Floating Point Systems, Cascade Microtech, Merix, Anthro, and other regional technology businesses. At its peak, the company was one of Oregon's largest employers, but its broad diversification eventually became a liability. In the 1980s it experienced weak earnings, layoffs, leadership changes, and a program of business disposals. Its printed-circuit-board manufacturing activity was spun off as Merix Corporation in 1994. By the 1990s and early 2000s, Tektronix had returned its focus to test and measurement. Digital sampling and signal-processing technology transformed the oscilloscope market, and Tektronix shifted substantial engineering effort toward digital oscilloscopes, waveform storage, analysis, and computer-assisted testing. Rick Wills, who became chief executive in 2000, pursued tighter spending and a narrower strategic focus after the technology-market downturn. Danaher acquired Tektronix in 2007. The brand later moved into Fortive after Danaher's separation of its industrial businesses, and subsequently into Ralliant after Ralliant was separated from Fortive. Tektronix continues to operate as a professional test and measurement brand.
