The Most Iconic Oscilloscopes in Electronics History The 7000 Series was the most iconic family of oscilloscopes in the history of technology. Introduced in 1969 by Tektronix, the sector’s leader at the time, this remarkable line of instruments defined an era and became a benchmark for generations of engineers, researchers, and technicians. Throughout the 1970s and well beyond, 7000-Series oscilloscopes were a constant presence in laboratories, universities, and industrial facilities around the world. Their modular plug-in architecture, exceptional flexibility, and outstanding performance embodied the engineering philosophy that made Tektronix synonymous with accuracy, innovation, and reliability. This book offers an in-depth exploration of the 7000-Series oscilloscopes, combining historical context, technical analysis, and practical insight into their design and restoration. Conceived as a continuation of Tektronix Epic Oscilloscopes, this work expands the subject into two volumes: the first devoted to mainframes and core technologies, the second focused entirely on plug-ins.

Verstehen und effektiv einsetzen Was in der Elektronik geschieht, ist mit bloßem Auge unsichtbar. Das Instrument, mit dem sich elektrische Signale präzise visualisieren lassen und die Effekte der Elektronik für uns sichtbar werden, ist das Oszilloskop. Leider wagt man sich beim Einstieg in die Elektronik oft ohne Oszilloskop vor. Man tappt dann im Dunkeln, sowohl praktisch als auch gedanklich. Die erste Beobachtung eines elektrischen Signals auf einem Bildschirm ist eine Offenbarung. Niemand möchte dieses Erlebnis danach noch einmal missen. Es gibt kein Zurück mehr. Wer in der Elektronik mit Freude und Verständnis vorankommen möchte, braucht unbedingt ein Oszilloskop. Dann stellt sich zunächst die Frage: Wie wählt man das richtige Oszilloskop aus? Und kaum ist diese Frage beantwortet, tauchen bereits die nächsten auf, die sich letztlich auf eine zentrale Frage reduzieren lassen: Wie nutzt man das Oszilloskop so, dass die Anzeige die Realität der Signale korrekt widerspiegelt? Rémy Mallard ist ein leidenschaftlicher Vermittler komplexer technischer Themen mit dem Talent, diese verständlich und fesselnd zu präsentieren. In diesem Buch beantwortet er wichtige Fragen zur Verwendung eines Oszilloskops und bietet zahlreiche Anleitungen, um die elektrischen Signale elektronischer Systeme zu erforschen und zu verstehen. Dank seines verständlichen Stils und seiner praktischen Einblicke ist dieses Buch ein wertvolles Werkzeug für alle, die ihr Elektronikwissen vertiefen möchten.
