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.

Understanding and Using Them Effectively
What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope.
Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back.
In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals?
Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.
An Illustrated Handbook of Vintage ‘Scopes Repair and Preservation
Tektronix oscilloscopes are true masterpieces of electronics and have helped mankind advance in every field of science, wherever a physical phenomenon needed to be observed and studied. They helped man reach the moon, find the cause of plane crashes, and paved the way for thousands of other discoveries.
Restoring and collecting these oscilloscopes is an exciting activity; it is really worthwhile to save them from the effects of time and restore them to their original condition. Many parts are quite easy to find, and there are many Internet sites, groups, and videos that can help you. Much of the original documentation is still available, but it is not always sufficient. This book contains a lot of information, descriptions, suggestions, technical notes, photos and schematics that can be of great help to those who want to restore or simply repair these wonderful witnesses of one of the most beautiful eras in the history of technology.
Component layouts included!
This book includes a nearly complete component layout plan of the original 545 oscilloscope, with relative reference designators. Not found in the original Tektronix manuals, this layout should prove invaluable to the repair technician.

Documentation
UNI-T UPO1202CS is a multifunctional, low-cost 2-channel digital phosphor oscilloscope with 200 MHz bandwidth and 1 GSa/s sampling rate. It can be widely used in the fields of electronic and electrical design, debugging, education and industrial design.
UPO1000CS series adopts parallel digital signal processing technology, which greatly improves the data processing speed and waveform capture rate. The original Ultra Phosphor technology can present the cumulative effect of the tested signal as a multi-layered afterglow. Compared with traditional digital storage oscilloscopes, the persistence of digital phosphor oscilloscopes can present three-dimensional waveform data of amplitude, time and signal intensity. Fast Acquire technology can accurately capture abnormal events such as video, jitter, noise and runt signals.
