Or the manuals from Tektronix equipment from the 70s and into the 80s. Have to
say it was pretty cool to have a manual that included schematics, a pretty full
theory of operation, and service info.

The best way is to start poking the probe into low-voltage circuits, to 
see what's there. Of course, a knowledge of the circuit diagram could be 
helpful.


Back when I was a tiny tot, there were these things called television 
sets, containing tubes and/or transistors. A company called SAMS made 
these wonderful repair guides called Photo-Fact schematic folders. They 
had dozens of oscilloscope traces printed right on the schematic 
diagrams, indicating what signal waveform and size to expect on each 
stage of the circuit. They also had photos of the chassis (PC boards or 
point-to-point wiring) calling out every component and every waveform's 
test point.


But these were television sets full of yummy high voltage, and the 
danger of getting a big shock or blowing up the scope probe was palpable.

It's a Tenma 72-320.  I assume it's analog, by the age, and weight.  It's
got a handle on top, and weighs about ten pounds.

Thanks for the info, I'll check that out.

Hello Shane,

that depends a little on the scope I would say. Is it digital, is it 
analog, does it have a built-in logic analyzer, does it weigh 5 tons or 
100g? ;-)


For the basic ideas, this is one of the first links that Google lists:

http://www.doctronics.co.uk/scope.htm

Regards,
Jens



Does anyone here, know of a good  " I have an oscilloscope, but don't
have a clue how to use it" guide?  I have had it for over a year, and
now that I'm getting into more programming, analog/digital, and logic
circuits, I need to figure it out.  Any help?

Shane
