Starting with this week’s lab, we are going to get comfortable with using an oscilloscope very quickly. Fortunately, modern digital ‘scopes have an accessible interface for simple waveform measurements and are therefore quite easy to get started on.
Here’s a very short introductory video on getting started with an oscilloscope:
(I really like the Keysight YouTube channel and I expect you will see me link to many of their videos over the course of this semester. I would also encourage you to browse their channels yourself. The content is interesting – and well-edited. And please share your own links, comments or questions!)
We mentioned in passing the effect of probe attenuation in the waveform measurement. Here’s a short video showing the effect of probe-loading (which you can think of as similar to the famous quantum observer effect where the act of measurement changes the thing you are trying to measure):
We also talked a bit about the history of analog oscilloscopes especially the versatile CRT. Tektronix is an important company in this history. Here’s a video that was apparently produced to mark the sad occasion of the closing of their manufacturing operation:
Finally, here’s a silly one:
