Testing circuits and devices with an oscilloscope

By popular request here is yet an other video on how to use an oscilloscope. This particular video shows how to test and make measurements with an oscilloscope by doing it with a very simple circuit.

- Everything you need to know playlist

- what is an oscilloscope and how to use it

- what is an audio generator (function generator) and what does it do

- Amplifying an Audio Generator signal with different amps

- How to calibrate an oscilloscope for accurate measurements

Great probe placement learning video! It's totally worth it as there are several ways to screw up measurements on even the simplest circuit. Like trying to use ch1 and ch2 simultaneously. Doh!

4:12 that bug definitely photo bombed this video, so to speak. Yes Mr X, I've watched a few videos regarding oscilloscope instruction but this is head and shoulders above the rest. You are a good teacher. Thank you sir.

a lot of the stuff about electricity kind of went over my head but this was very interesting :D

found your video looking for help on setting up a IV curve tracer, on a breadboard, 2 channels one for x one for y. I get good voltage display with the X, but I am stumped on getting the Y to show the current.how do I get the channel 2 probe in series to show current thru the DUT? do I just treat the channel 2 probe and its ground as a component in the circuit?
thanks

When testing radios etc, would you not have to isolate the component, circuit, before testing?

I don't see the positive and negative cables attached to the oscilloscope?

When you say audio generator, don’t you mean signal generator ?

In a real circuit you couldnt do this.
Your probe setup will be extremely noisy. Fue to the loisely coupled probe.(wires).
Also what you call negative on your probe is actually connected to earth ground. If you go probing resistors and components like this, your can to blow up your circuit, or your scope or both..

That’s not a circuit. What about on the actual PCB itself?
