THE WORKBENCH – EPISODE 5 – OSCILLOSCOPES Part 1
This week, George and Jeremy are joined at the Workbench by Alan Wolke W2AEW. Alan is a field application engineer for Tektronix, the world’s most well-known oscilloscope maker. He also has a YouTube channel that is chock full of great information for those wanting to better understanding oscilloscopes and test equipment in general. Alan joins us for a two part session to deep drive on oscilloscope features and applications. In part one, we introduce the oscilloscope, what it’s used for, some introductory concepts, and some comparisons of analog and digital scopes. We also take a look at probe quality.
Due to the length of the content, we will not have our usual news or Q&A sections. Look for those to be back in a future episode.
