Default Oscilloscope Training Class (long)

I helped teach a class on the basics of oscilloscopes to the New Jersey Antique Radio Club. This club is dedicated to the restoration and preservation of antique radios - mainly from the golden age of broadcasting. The class was geared entirely around analog scopes, since that's the type of scope that these guys would most likely come across or have access to for their radio restoration projects. We affectionately called the class "Scopes for Dopes", and it was a great success.


Fortunately, the session was videotaped. We had two projectors going - one with presentation slides, and one with a video camera feed that was focused on a few scopes on a table for demonstration.


NJARC Oscilloscope School a.k.a. "Scopes For Dopes"



To make it easier to navigate this long video - over 2 hours long, here is a list of time-stamps and the topics that begin at those timestamps. Using this "table of contents", you can easily move the youtube player location to the topic of interest.

Well I am a little upset because I didn't get any pizza but this is a great video so I am willing to overlook it.

I watched the first half and like what I see. I am going to try and watch the remainder this week.

Maybe approach a forum mod and see if it can be added to the list of videos?


How often is this class? Is it open to anyone? I might be willing to drive down to NJ if it is held again and it is open to say forum members.

If you are affiliated with Tektronix, a similar class on logic analyzers would be cool too.

I have a cheap PC based version but I suspect it is similar to the stand alone versions. It sure would be nice to learn about all of the functionality. I am barely scratching the surface on how I use it.

w2aew, I noticed your video linked to a clip shot in Camp Evans. I live right down the street from Camp Evans, and a couple years ago I went to a building a Xtal radio workshop by NJARC there. I would be interested about talking to you more about the group/becoming involved, would you be able to private message me about that?

Maybe it would just be nice it it was made a "sticky" to make it easy to find. I have another 20+ shorter instructional videos on my youtube channel that might be useful too.

The class was arranged by the NJ Antique Radio Club - it isn't a regular event. I have some friends in the club, and they asked if I would be willing to put some material together and present it to the group - that's how it came about.
