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.

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.

The MicroMod DIY Carrier Kit includes five M.2 connectors (4.2mm height), screws, and standoffs so that you can get all the special parts you may need to make your own carrier board. MicroMod uses the standard M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic ‘key’ on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the ‘E’ key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The ‘E’ key is fairly common so a user could insert an M.2 compatible Wifi module. Still, because the screw mount doesn’t align, the user would not secure an incompatible device into a MicroMod carrier board.

SmartScope is a compact 2-channel USB oscilloscope with a bandwidth of 30 MHz and a sampling rate of 2x 100 MSa/s. It is compatible with all major platforms, including Windows, macOS, Linux, and Android. The operation and display of measurement signals are done via smartphone, tablet, or PC. Additionally, a logic analyzer and a signal generator are integrated.
Even more, you can get mobile with it: take the SmartScope on the road, thanks to the single-cable connectivity. Everything is going to be intuitive: pointing, pinching and swiping finally replaces the clunky interfaces of old scopes.
With the SmartScope you develop your digital interfaces using the 100 MS/s logic analyzer. With this tool you can design any signal you want using Excel, then upload it to the built-in Arbitrary Waveform Generator (AWG). At the end capture the voltage at any point of your design at 100 million times each second.
The Software for the support of Windows / macOS / Linux / Android and Export formats (Excel .csv / Matlab .mat) are given.
