An illustrated chronicle of Teknology for collectors and restorers
Oscilloscopes have made a major contribution to the advancement of human knowledge, not only in electronics, but in all sciences, whenever a physical quantity can be converted into a timerelated electrical signal.
This book traces the history of a crucial instrument through many Tektronix products. This is the company that invented and patented most of the functions found in all oscilloscopes today. Tek is and will always be synonymous with the oscilloscope.
In nearly 600 pages, with hundreds of gorgeous photos, diagrams, anecdotes, and technical data, you'll travel through the history of Tektronix in a superb collector's edition with a technical point of view. The author is not afraid to get his hands dirty restoring his own Tek equipment. The journey starts in the early 1950s. It ends in the '90s, after exploring the ins and outs of the most interesting models in the 300, 400, 500, 5000, 7000, and 11000 series, from tubes to advanced hybrid technologies.
