Got an Oscilloscope? Here’s Why You Should


Tom AE5I talking about oscilloscopes

Tom AE5I gave a talk at the September meeting of CMSARA about oscilloscopes. What most hams lack is a global view of the family of oscilloscope instruments rather than a limited experience of one type. Tom Brown’s passion in laboratory bench equipment is the oscilloscope. It showed! He not only knows the technical elements of the history of oscilloscope development but the “players” who were instrumental in each step.

The types of oscilloscopes he covered included: Analog, Digital, Real-Time Sampling, Storage (Analog), and Digitizing. To most hams, these various types of devices are…well, just confusing unless you’ve used ‘scopes before. In an uncomplicated way, AE5I conveyed how and why these various designs came to be. He also filled-in the gaps with the specific engineers who developed key types of innovation leading to the evolution of oscilloscope design. How spectrum analyzers are variants of ‘scopes was an intriguing aspect of last month’s talk.

This talk was the global overview preparation for next month’s Special Madison Event on Tuesday, October 12, 2015, at a site to be announced on this website by Mike Flanagan WM5A, Special Events Coordinator for CMSARA. Tom AE5I will have a number of his own oscilloscope instruments on-site and live at this October talk. Attendees will be able to see the screen and controls very clearly from the audience through the new Elmo display device donated to the Association. This will be a great informative program. Stay tuned!

AE5I’s slides from Part 1 of his oscilloscope talk in PDF format are available here.
