Oscilloscope. What is it?

(1/6) > >>

Professor Fudge:
What the heck is this Oscilloscope thingy?

So Its a piece of machinery that measures the wave forms created by a circuit right?

Why do you need wave forms coming out of a circuit? How do you know they are looking right?

If I had an oscilloscope how would I test some random circuit to see waves and stuff?

Yes I am a noob. I used google and wiki and stuff but I am still confused.

Why is this a must have tool for you electronic fellas?

Kiriakos-GR:
The use of the Oscilloscope thingy, its part of the school training , of any electronics engineer.

So if you are not aware of it , it translates that you are not one of them.
Or not in the right age .
Or some one who just asking of curiosity.

Generally speaking , Oscilloscope its an device that you need to be trained so to use it.

With out this training , for the most people are just an box with an screen.   

djsb:
All you need to do is buy one and teach yourself how to use it properly. There are books available to help and most of what you need to know can be picked up from experimentation. The idea that knowledge is restricted to the few and only available in Schools/colleges is distasteful to me. All you need is curiosity and the willingness to learn.

RayJones:
Put simply if you do anything more than DC switching in electronics you are dealing with some form of pulse or AC waveform.

The oscilloscope allows one to view the waveforms, ala signals throughout the equipment.
If these signals are incorrect, the equipment will usually malfunction, that is why it is invaluable as you can "see" where things go pear shaped.

As for knowing what to look for, that comes about by understanding what you'd expect to see, which in itself requires an understanding of how the circuit is meant to operate, and the usual signals applied/generated.

A dual trace oscilloscope allows you to view two waveforms simultaneously, which can provide valuable timing information / violations especially when dealing with digital circuitry.

As for going to school to learn how to use one, BAH, the best learning is done on your workbench at home, but always have due regard to safety and don't go probing things like the mains.

Professor Fudge:
Hey thanks Ray. I'll just see if I can get my hands on a cheap one and mess around with it. So the design of the electronics is based around the wave form being proper? This is interesting. I have a lot to learn. Kiriakos-GR you typed a lot for not saying anything.  ;D
