Tektronix
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.
