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.
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 John
I never used an IV curve tracer, but normally when measuring voltage with something like a multimeter, the probe goes in parallel and with current the probe goes in series. Based on this my best guess would be ... yes, treat the Y probe like a component in the circuit. Though I would put the Y probe as close to the component(s)/ part you want to test. Also, do you know if you have a voltage drop or some kind of meter loading with the Y probe? ... It might be something you want to consider.
Generally no, especially for low voltage DC circuits and even more so for digital circuits with a clock cycle. That does not mean there is some odd exception that I can't think of right now. Though for old school electronic devices (think tubes and stuff made before the 1970's), most of them ran on high voltage AC and lack modern safety features (that we take for granted today). So you would have to isolate the device's circuits to prevent from being shocked or injured by them. Though this isolation is more for safety rather than testing.
Are you using a scope probe instead of alligator clips? If so the retractable clip at the tip would be the equivalent of the red wire (positive) and the grounding wire would be the equivalent of the black wire (negative)
technically no, as the Audio Generator says, "AUDIO GENERATOR WA-44C" on the front panel below the frequency selector dial. Audio Generators will generate a signal in the audible range (about 20 Hz to 20 KHz) and some signal generators will not do frequencies that low. Plus, when the generator does a wide range of frequencies and wave types, some people might refer to it as a function generator. Judging by the fact that my generator does between 1 Hz to 200 KHz and the audible audio range is a majority of what the generator covers, I think it's safe to say that it's an Audio Generator. Though, some people will say that an Audio Generator is a type of Signal Generator as its generating an audio signal. Also, most people will use the terms, Audio generator, Signal Generator and Function Generator interchangeably. So, technically no, but in some cases, you could say kind of yes.
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..

Thank you so much for the complements. Glad the video were very informative. This is why I started making these video
Hey buddy, I just saw your video, and I have to tip my hat to you! You did an amazing job! Thank you sir!
@@paulfranken4493 thank you and I'm glad the video helped
Very clever demo. Thanks.
Thank you for the compliment. I'm glad the video was helpful.
@@JosephXthanks but tgat signal is calles courant Imax or tension Umax ???

a lot of the stuff about electricity kind of went over my head but this was very interesting :D
When testing radios etc, would you not have to isolate the component, circuit, before testing?
Generally no, especially for low voltage DC circuits and even more so for digital circuits with a clock cycle. That does not mean there is some odd exception that I can't think of right now.

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

@@JosephXSo in escencr you are measuring sections of a circuit at a time to find where the problem is located? I correct?
Thank you
@@JosephXThank you. Sorry for the late response and yes I would have been using a probe. So I understand know how you were using the alligator clips.
Can these measurements be taken on a live circuit? Thanks.
Quick and easy good video
When you say audio generator, don’t you mean signal generator ?

Great thanks for this
Your welcome, glad you like the video
That’s not a circuit. What about on the actual PCB itself?
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..
