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.[2][3]

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.[4] This oscilloscope—refined and developed by Tektronix—was the model 511 produced from 1947 to 1953.[5] The model 511 was a triggered-sweep oscilloscope. The first oscilloscope with a true time-base was the Tektronix Model 513.[6]

The leading oscilloscope manufacturer at the time was DuMont Laboratories. DuMont pioneered the frequency-synch trigger and sweep.[7] Allen DuMont personally tried the 511 at an electronics show and was impressed, but when he saw the price of $795 (equivalent to $11200 today),[8] 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.[9]

Tektronix was incorporated in 1946 with its headquarters at SE Foster Road and SE 59th Avenue in Portland, Oregon,[10] just six blocks from Murdock's first family home.[11] In 1947 there were 12 employees. Four years later, in 1951, Tektronix had 250 employees.[10] Murdock and Vollum were known humanitarians and sought to operate their business as one might run a large and caring family.[12] 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.[13]

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).[10] The company then moved its headquarters to this site, following an employee vote.[10]

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.[14]

1955–1969

[edit]

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.[10] Construction began in 1957 and on May 1, 1959, Tektronix moved into its new Beaverton headquarters campus,[10] on a 313-acre (1.27 km2) site which came to be called the Tektronix Industrial Park.[15]

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.[16]

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.[17]

Model 564, the first mass-produced analog storage oscilloscope

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.[18]

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.[19] 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.[20]

1970–1985

[edit]

In 1974, the company acquired 256 acres (1.0 km2) in Wilsonville, Oregon where it built a facility for its imaging group.[10] By 1976, the company employed nearly 10,000, and was the state's largest employer.[10] Tektronix's 1956 expansion and, in 1962, Electro Scientific Industries' similar move to Washington County and expansion are credited with fostering the development of a large high-tech industry in Washington County, a number of firms which collectively are often referred to as the "Silicon Forest".[15]

For many years, Tektronix was the major electronics manufacturer in Oregon, and in 1981, its U.S. payroll peaked at over 24,000 employees. Tektronix also had operations in Europe, South America and Asia. European factories were located in Saint Peter's, Guernsey (then in the European Free Trade Association) until 1990,[21] Hoddesdon (Hertfordshire, UK) and Heerenveen, Netherlands (then in the European Common Market). Some oscilloscopes marketed in Europe and the UK were sold under the brand name Telequipment but many in the UK used the Tektronix brand name in the 1960s and '70s.

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.[22] Under the Sony-Tektronix name, the 300 series oscilloscopes were lightweight and totally portable. They replaced the model 321/321A oscilloscopes. Examples of the Sony/Tektronix models were 314, 323, 335 and 370.

Tektronix 7854 oscilloscope with other equipment

During the early 1970s, Tektronix made a major design change to their oscilloscopes. The 5000 and 7000 series oscilloscopes maintained the plug-in capabilities that originally started with the 530 and 540 series; however, the choice of plug-ins was even greater. These scopes used custom designed integrated circuits fabricated by Tektronix. The CRTs were all rectangular and were all fabricated by Tektronix. These oscilloscopes provided on screen controls setting. The 5000 series was the general purpose line while the 7000 series were capable of a wide variety of applications and could accept as many as 4 plug-ins. One model, the 7104 (introduced 1978), was a true 1 GHz bandwidth oscilloscope.[23]

Beginning with the firm's first cathode ray oscilloscopes, Tektronix has enjoyed a leading position in the test and measurement market. Although its equipment was expensive, it had performance, quality, and stability. Most test equipment manufacturers built their oscilloscopes with off-the-shelf, generally available components. But Tektronix, in order to gain 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 custom ICs for their equipment.[citation needed]

Tektronix instruments contributed significantly to the development of computers, test, and telecommunications equipment and to the advancement of research and development in the high-technology electronics industry generally.

As time went on, Tektronix fabricated more and more of their electronic parts. This led to very specialized skills and talents which in time led to employees forming new businesses. Some former Tektronix employees left to create other successful "Silicon Forest" companies. Spin-offs include Mentor Graphics, Planar Systems, Floating Point Systems, Cascade Microtech, Merix Corporation, Anthro Corporation and Northwest Instrument Systems (NWIS) – later renamed to MicroCase. Even some of the spin-offs have created spin-offs, such as InFocus. As Tektronix fabricated more specialized parts, they spread out their product base to include logic analyzers, digital multimeters and signal generators. The TM500 and TM5000 rack mount series was born featuring custom designed test instruments chosen by the buyer.

During this period, Tektronix acquired what were sold as the 8000 and 8002 Microprocessor Development System (MDS), the 8000 being a software development system running editors and cross-compilers with twin floppy disk storage, while the 8002 could be fitted with real-time emulators for several processors including the 8080, Z80 and 6502. These were later replaced by the 8540/8550/8560.[24] The 8550 was a standalone development system capable of being fitted with real time emulation hardware for several different processors. The 8560 emerged just after Bell Labs were able to sell UNIX commercially, and ran a mildly modified version of Version 7 UNIX, called TNIX, supporting 4 or 8 (depending on how many I/O processor cards were fitted) serial terminals, with a special High-Speed Input/Output, based on RS-422, to connect to a remote 8540. There was a hard drive of about 34MB, later increased, and a variable amount of RAM depending on the processor card fitted, which was either a DEC LSI11-23+ or a LSI11-73, which had a wider address bus as well as a higher clock speed. The final upgraded variant was the 8562. The 8540, of which several could be connected to the 8560, contained emulation hardware similar to that available for the 8550, including RAM cards, Trigger Trace Analyser, 1 or 2 processor emulator cards, each with external probe, etc. The 8540 had no software development capability, but worked with the 8560, or other systems such as a VAX, which would provide the software development environment. It was unique in its day, in that the serial terminal could be connected to the 8540, on the bench, or to the 8560, and would pass UNIX commands automatically to the 8560, which passed emulator commands back to the 8540 for execution, completely transparently. Thus a complete compile, link, load and emulate session could be run from a UNIX shell script, a facility probably not seen on any development system since. The 8540/8550/8560 supported many 8-bit and 16-bit microprocessor types, with a change of emulator cards and probes, and installation of assembler and possibly compiler software, and did not require any particular code to be linked in to the user's code to facilitate register tracing at breakpoints, a shortcoming of the only real alternative multi-manufacturer MDS of that era, by HP. However, an impressive feature was that by including a special instruction sequence, typically a double NOP followed by a call to a specific address, the emulator would generate a "Service Call" to take whatever action the user required, and continue execution. This for example could allow UNIX to write variables to a log file as commanded by the running program on the emulated microprocessor.

It is not clear at present why Tektronix eventually withdrew from the MDS business, as their products were highly regarded.

1986–2006

Tektronix began to face big challenges to its business structure. In the 1980s, Tektronix found itself distracted with too many divisions in too many markets. This led to decreasing earnings in almost every quarter. A period of layoffs, top management changes and sell-offs followed. In 1994, Tektronix spun off its printed circuit board manufacturing operation as a separate company, Merix Corp., headquartered in Forest Grove, Oregon.[25] Eventually, Tektronix was left with its original test and measurement equipment. Upon his promotion in 2000, the current CEO, Richard H. "Rick" Wills, carefully limited corporate spending in the face of the collapsing high-tech bubble. This led the way for Tektronix to emerge as one of the largest companies in its product niche, with a market capitalization of $3 billion as of April 2006. However, this failed to prevent it from becoming an acquisition target, and Tektronix was acquired by Danaher Corporation in 2007.

With the advancement in signal sampling techniques and digital processing, oscilloscope manufacturers found a new horizon in the market: the ability to sample the signal and digitize it for real time viewing or digitally store it for future use and maintain the integrity of the waveform. In addition a computer can be integrated with the scope to store many waveforms or instruct the scope to do further analysis. Color-enhanced waveforms can be produced for ease in identification.

Tektronix was heavily involved with designing digital sampling oscilloscopes. In the mid-1980s, they quickly replaced their analog oscilloscopes. Their 400, 5000 and 7000 series oscilloscopes were replaced with a new generation of digital oscilloscopes with storage capability, the 11000 and TDS series. The 11000 series were large rack mount laboratory models with large a flat CRT face and had touch screen, multiple color, and multiwaveform display capability. They were still plug-in units and could accept the older 7000 series 7- plug-ins and the new 11000 series 11A- plug-ins. The TDS series replaced the 300 and 400 series portable line. They had the same panel layout but with enhanced storage and measuring capabilities. During this period Tektronix would also expand its test equipment line to logic analyzers, signal generators etc.

By the mid-1990s the use of the CRT was dropped and Tektronix started using LCD panels for display. The 11000 series would be replaced by the MSO (Mixed Signal Oscilloscope) which featured a color active matrix LCD. The TDS continued but with LCD panels starting with the TDS-210. In the TDS models, the lower priced models replaced the last of the 2000 series analog scopes and featured monochrome display while the higher end models were color LCD models which were more like the older 400 series scopes in performance. Spinoffs of the TDS was the TBS storage scope series. Later Tektronix would replace the 200 mini oscilloscopes with the TH series hand held digital oscilloscopes. All TDS and spinoff series with LCD display are totally portable (light weight and can run AC or on batteries).

2007–present

[edit]

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.[26] The deal closed five and a half weeks later, with 90 percent of TEK shares being sold in the tender offer.[27] 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.

The digital oscilloscope line that was introduced in the 1990s (MSO, TDS, TH series) are still being manufactured in some form.[28]

On February 1, 2016, Tektronix introduced a new logo design, replacing a logo that had been in use since 1992, and indicated a shift in strategy to offer measurement products tailored for specific fields such as computing, communications and automotive.[29] Danaher spun off several subsidiaries, including Tektronix, in 2016 to create Fortive.[30]

Tektronix Video, commonly known for their waveform monitors, was merged with Telestream via an agreement with Fortive on April 25, 2019.[31]

Production of oscilloscopes has moved to China in recent years.

Overview

Founding and Early Operations

Tektronix was founded on January 2, 1946, as a partnership named Tekrad by Howard Vollum, Jack Murdock, Miles Tippery, and Glenn McDowell, all veterans who had served in electronics-related roles during World War II. The founders aimed to capitalize on the postwar surplus of military electronics equipment by designing and producing innovative oscilloscopes to meet the growing demand for precise signal testing in the burgeoning electronics industry. Initial operations began modestly in the basement of Murdock's house on Southeast Foster Road in Portland, Oregon, before relocating to a small rented space on S.E. 59th Avenue in Portland, Oregon, where the team focused on developing a triggered oscilloscope to overcome the limitations of existing free-running models that struggled with unstable waveforms. The partnership's name was changed to Tektronix, Inc., shortly after incorporation on February 4, 1946, to avoid confusion with a similar California firm. Facing significant financial constraints in their early years, the founders pooled limited resources, with each contributing approximately $2,600 in startup capital, and relied heavily on Vollum's personal funds and ingenuity to sustain operations amid economic uncertainties. Vollum, an electronics expert from the U.S. Army , led the design efforts, drawing on surplus components to prototype their flagship product. The company's first breakthrough came with the release of the Model 511 in 1947, the first commercially successful triggered , which featured up to 1 MHz bandwidth, time-base triggering for stable waveform display, and automatic capabilities that revolutionized . Priced at $795, the portable 65-pound instrument, enclosed in a durable metal case, quickly gained traction despite initial production challenges. Early sales were modest and targeted local needs, with the first unit sold in May 1947 to the for biomedical research, followed by orders from Portland-area radio stations through their affiliated retail outlet, Hawthorne Electronics. emerged as an early major customer, purchasing scopes for its engineering labs and providing valuable feedback that helped refine designs, though the company grappled with cash flow issues and slow market adoption in the immediate postwar period. By 1950, growth necessitated expansion, leading to a relocation to a new facility at Sunset Highway and Barnes Road near , in 1951, which supported increased production and marked the company's shift toward a more structured corporate operation. This move solidified Tektronix's foundations, enabling it to employ 250 people by that year and lay the groundwork for broader industry impact.

Current Structure and Ownership

Tektronix is headquartered in , and employs approximately 3,000 people globally as of 2023, with a strong emphasis on in test and measurement technologies. The company's ownership has evolved through several corporate transactions: it was acquired by in 2007 for $2.85 billion, then spun off as part of in 2016, and most recently separated into Ralliant Corporation in June 2025 as part of Fortive's division into two independent public companies. As of 2025, Tektronix operates as a subsidiary of Ralliant Corporation, led by President Christopher Bohn, while Ralliant's CEO Tami Newcombe oversees the broader precision technologies portfolio, focusing on integrating advanced measurement solutions across segments. Tektronix contributes significantly to Ralliant's precision technologies revenues, with Ralliant reporting $503 million in for Q2 2025; in 2023, the company optimized its Beaverton campus by selling 39 acres of land to . Under its current structure, Tektronix has shifted strategically toward tailored solutions for emerging fields, including communications, e-mobility, and , to address demands in high-speed signal analysis and energy-efficient testing.

Historical Development

Inception and Initial Growth (1946–1954)

In the post-World War II era, Tektronix was founded amid a surge in demand for advanced , driven by the revolution and technologies. Howard Vollum, a 1936 physics graduate from who had served as an captain developing systems during the war—earning two Legions of Merit—teamed up with Jack Murdock, a Portland native and Coast Guard radio technician with prior business experience running a radio repair and appliance shop since 1935. Their partnership formed the core of the company, incorporated as Tekrad in January 1946 and quickly renamed Tektronix to avoid confusion with a California firm; Vollum focused on innovative instrument design, while Murdock handled sales and operations, emphasizing customer service and equitable profit-sharing. A pivotal milestone came in 1947 with the launch of the Model 511, Tektronix's first —a portable, 65-pound unit priced at $795 featuring automatic triggering and ±5% accuracy, a vast improvement over competitors like DuMont's bulky, uncalibrated $2,000 models. Production ramped up steadily from the company's initial Portland storefront, reaching an output of approximately 300 units by 1950, with sales climbing from $27,000 in 1947 to $257,000 in 1948 as international exports began, including the first overseas sale to Sweden's L.M. Telephone Company. This growth established Tektronix as an emerging leader in s, though early operations remained modest with just 12 employees by 1947. In 1949, Tektronix introduced the Model 513, an enhanced portable oscilloscope with DC coupling and 18 MHz bandwidth, addressing limitations in the 511 and broadening appeal for laboratory and field use. Early growth faced headwinds from the Korean War (1950–1953), including material shortages that strained supply chains amid surging military demand for oscilloscopes; competition intensified from established players like General Radio, but Tektronix resolved these by securing government contracts that prioritized production and stabilized operations. By 1950, the company relocated from cramped Portland facilities to a larger site on a Beaverton farm, expanding to a 20,000-square-foot building on four acres to support scaling operations and a growing workforce. In 1951, a public stock offering on October 23 raised essential capital—approximately $100,000—for further expansion, coinciding with net sales surpassing $4 million that year.

Expansion and Technological Breakthroughs (1955–1969)

In the mid-1950s, Tektronix undertook significant infrastructure expansion to support its burgeoning operations. The company purchased 313 acres of land in , in 1956, with construction of its new headquarters campus beginning the following year and the relocation completed on May 1, 1959. This move from Portland facilitated scaled production and administrative efficiency, contributing to rapid workforce growth from a few hundred in the early 1950s to 3,515 employees by 1960, making Tektronix Oregon's largest private employer at the time. Accompanying this expansion, annual revenues surged approximately 4,000 percent over the decade, reaching $43 million in 1960, driven by demand for advanced test equipment amid the electronics boom. Technological advancements defined the period, with Tektronix pioneering portable and storage oscilloscopes that addressed emerging needs in , , and research. The Model 321, introduced in 1960, marked the company's first fully portable, battery-operated oscilloscope, featuring a 5 MHz bandwidth and nearly all-solid-state design for field use; it was considered for integration into NASA's ground support equipment and in-flight test systems. In 1962, the Model 564 debuted as the first commercially successful analog storage oscilloscope, enabling the capture and persistent display of transient signals, which revolutionized single-shot event analysis in high-speed electronics. The 453 series followed in 1965, offering a compact, 50 MHz dual-trace portable design suited for complex system troubleshooting, such as in IBM's System/360 computers, and later incorporated into Tektronix's internal education programs for design training in the late 1960s. Market expansion accelerated alongside these innovations, as Tektronix established its first European manufacturing facility in in 1958 to tap into the growing Common Market, followed by land acquisition in the in 1960 for further production. Entry into began through joint ventures, including a 50-50 with that operated into the 1970s. By 1969, consolidated orders reached $142.8 million, with earnings of $13.4 million, reflecting oscilloscopes' dominance at approximately 75 percent of the global . Tektronix's growth also seeded Oregon's "" tech ecosystem, acting as an anchor by attracting talent and inspiring spin-offs that diversified the region's high-tech landscape.

Peak Employment and Product Diversification (1970–1985)

During the 1970s, Tektronix experienced significant growth, marked by the introduction of the 7000 series modular oscilloscopes in 1973, which featured a versatile plug-in architecture enabling bandwidths exceeding 100 MHz and supporting a wide array of specialized modules for advanced signal analysis. This innovation built on earlier storage oscilloscope technologies and solidified Tektronix's dominance in high-performance test equipment, contributing to expanded market share amid rising demand from electronics and defense sectors. The company's diversification efforts accelerated during this period, with the launch of the Model 7D01 in 1973—a 16-channel plug-in for the 7000 series that allowed for and timing , addressing the growing complexity of microprocessor-based systems. Tektronix also advanced its lineup in the 1970s, introducing portable models like the 492, which offered improved and frequency coverage for RF troubleshooting in and . By the 1980s, diversification extended to test gear, bolstered by the 1974 acquisition of Grass Valley Group, which specialized in equipment including waveform monitors and vectorscopes for and PAL standards. Employment reached its zenith in 1981 at over 24,000 workers worldwide, with approximately 15,000 based in , reflecting the scale of operations across expanded facilities on the 300-acre Beaverton campus developed in the late and further built out during the . This growth occurred despite economic headwinds, which contributed to a 34.7% earnings drop in fiscal 1971, prompting temporary layoffs. The further strained global supply chains and energy costs, yet Tektronix adapted by focusing on efficiency and international sales, achieving annual revenue of approximately $1.2 billion by 1985. Amid this expansion, Tektronix contributed to Oregon's emergence as a technology hub through and community programs via the Tektronix Foundation, established in 1952 but active in the and with donations of equipment to educational institutions and support for local STEM initiatives. The company fostered spin-offs, such as Floating Point Systems in 1970, which employed former Tektronix engineers and spurred high-tech clustering in the Portland area, while employee profit-sharing and programs enhanced workforce development and regional economic vitality.

Restructuring and Challenges (1986–2006)

In the mid-1980s, Tektronix encountered severe financial pressures stemming from and intensifying global competition, particularly from low-cost Japanese manufacturers in the oscilloscope market. The company's workforce, which had peaked at over 24,000 employees in 1981, began a steep decline amid stagnant sales of test equipment; by the end of fiscal , employment had dropped from over 20,000 to just above 17,000, with further cuts accelerating through the late 1980s.
