Tektronix, Inc., historically widely known as Tek, is an American company best known for manufacturing electronics test and measurement devices such as oscilloscopes, logic analyzers, and video and mobile test protocol equipment. Originally an independent company, it is now a subsidiary of Ralliant, a spinoff from Fortive.
History
1946–1954
The company traces its roots to the electronics revolution that immediately followed World War II. It was founded in December 1945 as Tekrad. The name was similar to that of a California company, Techrad, so in 1946, the four partners, Howard Vollum, Jack Murdock and Miles Tippery, who had both served in the Coast Guard, and accountant Glenn McDowell, formed Tektronix, Inc. Each contributed an initial $2,600 for equal shares. Howard Vollum had graduated in 1936 from Reed College with a degree in physics and a keen interest in oscilloscopes, then worked as a radio technician at Jack Murdock's Murdock Radio and Appliance Company (M.J. Murdock Company) prior to the outbreak of war, during which he served in the Signal Corps. Following the founding of Tektronix, Vollum invented the world's first triggered oscilloscope in 1946, a significant technological breakthrough. This oscilloscope—refined and developed by Tektronix—was the model 511 produced from 1947 to 1953. The model 511 was a triggered-sweep oscilloscope. The first oscilloscope with a true time-base was the Tektronix Model 513. The leading oscilloscope manufacturer at the time was DuMont Laboratories. DuMont pioneered the frequency-synch trigger and sweep. Allen DuMont personally tried the 511 at an electronics show and was impressed, but when he saw the price of $795 (equivalent to $11460 today), which was about twice as much as his equivalent model, he told Howard Vollum at the show that they would have a hard time selling many. Tektronix was incorporated in 1946 with its headquarters at SE Foster Road and SE 59th Avenue in Portland, Oregon, just six blocks from Murdock's first family home. In 1947 there were 12 employees. Four years later, in 1951, Tektronix had 250 employees. Murdock and Vollum were known humanitarians and sought to operate their business as one might run a large and caring family. In 1978, Tektronix was named by authors Robert Levering and Milton Moskowitz, et al., as among The 100 best companies to work for in America in their book of the same name. By 1950, the company began building a manufacturing facility in Washington County, Oregon, at Barnes Road and the Sunset Highway and, by 1956, had expanded the facility to 80,000 square feet (7,000 m2). The company then moved its headquarters to this site, following an employee vote. A detailed story of Howard Vollum and Jack Murdock along with the products that made Tektronix a leader in oscilloscopes can be found at the Museum of Vintage Tektronix Equipment.
1955–1969 In 1956, a large property in Beaverton became available, 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, on a 313-acre (1.27 km2) site which came to be called the Tektronix Industrial Park.
In the late 1950s (1957–58), Tektronix set a new trend in oscilloscope applications that would continue into the 1980s. This was the introduction of the plug-in oscilloscope. Starting with the 530 and 540 series oscilloscopes, the operator could switch in different horizontal sweep or vertical input plug-ins. This allowed the oscilloscope to be an adaptable test instrument. Later Tektronix added plug-ins to have the scope operate as a spectrum analyzer, waveform sampler, cable tester and transistor curve tracer. The 530 and 540 series also ushered in the delayed trigger, allowing to trigger between a sweep rather than at the beginning. This allows more stable triggering and better waveform reproduction. In 1961, Tektronix sold its first (possibly the world's first practical) completely portable oscilloscope, the model 321. This oscilloscope could run on AC line (power mains) or on rechargeable batteries. It also brought the oscilloscope into the transistor age (only a Nuvistor ceramic tube was used for the vertical amp input). A year and a half later, the all-transistor model 321A came out.
The 560 series introduced the rectangular CRT to oscilloscopes. In 1964 Tektronix made an oscilloscope breakthrough: the world's first mass-produced analog storage oscilloscope, the model 564. Hughes Aircraft Company is credited with the first working storage oscilloscope (the model 104D) but it was made in very small numbers and is extremely rare today. In 1966, Tektronix brought out a line of high-frequency full-function oscilloscopes called the 400 series. The oscilloscopes were packed with features for field work applications. These scopes were outstanding performers often preferred over their laboratory bench models. The first models were the 422, a 16 MHz bandwidth and the 453, a 50 MHz bandwidth model. The following year the 454, a 150 MHz portable. These models put Tektronix well ahead of their competitors for years. The US military contracted with Tektronix for a model 453 "ruggedized" for field servicing. The 400 series models would continue to be popular choices in the 1970s and '80s. In addition the styling of the 400 series would be copied by Tektronix's competitors. 400 series oscilloscopes were still being used as of 2013.
