Dirt cheap and simple scope-based component tester - curve tracer

<< < (3/13) > >>

Fraser:
Here is some more information on using I/V curve analysis units on components.
I also attach the Huntron US Patent for the original 'Tracker' design.
The schematics and service manuals for many of the Huntron Trackers are available FOC from several sites in the internet.

Thanks. I have often searched for the original kit from ~1980. It came with nice sloping front metalwork and nice decals.
The PCB also had a lot more parts, took me ages to assemble, if my memory is any good. Elektor were so ahead of their time.

Saw that, not as impressed. Maybe I'm too cynical these days :-)

This is a great video for beginners. And I just watched another four or five. Your videos go right to the heart of the questions that have been bugging me and strike just the right mix of theory and demonstration. Please keep them coming. I just watched "Use a scope to measure the length and impedance of coax" and with it I feel I much better understand characteristic impedance, termination, etc. Thanks!!

Ken - thank you!  I'm glad I'm hitting the "sweet spot" with you.  Please feel free to shoot me a message with ideas for video topics that you'd like to see.

IET also made a curve tracer.  It was the STS-1600.

The display was LCD dot matrix, and it is rather slow to update, but it does work.
