TEKTRONIX TYPE 546.
Entirely based on tubes technology is a monument of highest engineering combined with top level hand made wiring.
With an heavy load of Steel was my friend sustaining in a job which todays isn't anymore..... long time ago.
The TEKTRONIX TYPE 546 is a 50MHz scope that takes letter-series and 1-series plug-ins. It has two identical timebases and , when used with the 1A1, 1A2, or 1A4, has the ability to display one input with one time scale and another input with a different time scale. The effect is similar to a dual-beam scope assuming that the input signals are repetitive. This "Sweep Switching" feature differentiates the 547 from the TEKTRONIX TYPE 546 .
The TEKTRONIX TYPE 546 uses the Tektronix 154-0478-00 CRT.
The Tektronix 546 is like a 547, but without synchronized alternating timebases. It uses letter-series and 1-series plug-ins. Functionally, it is like a 545B, but with tunnel diode triggering and 50MHz vertical bandwidth. There is also a rackmount version, the RM546.
The TEKTRONIX TYPE 546 is less common than the 545 or 547.
Tektronix, Inc. is an American company best known for its test and measurement equipment such as oscilloscopes, logic analyzers, and video and mobile test protocol equipment. In November 2007, Tektronix became a subsidiary of Danaher Corporation.
Several charities are or were associated with Tektronix, including the Tektronix Foundation and the M.J. Murdock Charitable Trust in Vancouver, Washington.
The company was honored at the 2008 Technology & Engineering Emmy Awards for development of monitoring systems for ATSC & DVB transport streams.
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.
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.
