Function Generator Tutorial in HD

[tangocukedi1]

How do you give it a negative amplitude?

[alvastornado]

Thank you for inspiring videos in the magic world of electronics! have a question here sir if i may ask....i have connected the FG probe to a npn transistor to pulse control an higher voltage dc circuit, but can i ground the probe to the negative terminal of the high voltage dc??.. or do i need to use a resistor?..

[darkerthebetter]

So if you used a scope probe lead from the generator, how did you connect it to the scope in the vid, did you have a similar probe from that and just join them at their tips ? sorry if this is silly to some but im learning, and its better to ask ! :)

[Afrotechmods]

@darkerthebetter Yeah tip to tip and ground to ground for observing waveforms. This assumes a 1X probe is being used.

[acadienvid]

@Afrotechmods because of you, I'm back to my old hobby. Thanks ! I was getting tired of programming I needed something else, electronic is what I was looking for but wasn't able to find good video, yours are perfect for me. Continue your good work!

[sent143fy]

your video is like one stone hit 4 birds, your video is funny, educational, well explained, in detail and complete. what can i say more! thank you very much.

@afrotechmods Nice videos afro. Got myself a function generator n' oscilliscope recently to do my own labs at home than at school. and i find your videos very useful. Thanks!!

[udiweizman]

cheers dude :)

Hi Afro.. Isn't it the case that our eyes actually stop seeing the flashing effect of light's etc at anything beyond about 45-50Hz? In the video you mention 1000Hz.

Not trying to nit-pick or anything afro as I find you're videos great, & helpful too. I'm just wondering what you're referring to here in case I'm missing something.

@orbiter8 If you move the LEDs around you can clearly see 50Hz LEDs blinking on and off in a persistence of vision trail. Around 1kHz it looks like a continuous stream of light even if you are moving the LEDs around pretty quick.

[orbiter8]

@Afrotechmods Ah yes, I just did that & see now what you're referring to. Thank you for replying.

[judgenap]

this is brilliant . Especially connecting directly to the the transistor I will be doing just that.

[judgenap]

All your videos are fantastic . Thanks a lot. I have to get a good function generator.

[drumstick9000]

so does this have an output of 12V?

[pokerus987]

He has the technology maaaaan

[RodBeauvex]

If you connected a small speaker like those you used to find in PC cases directly to the terminals you hooked the probe to, would you hear a tone?

[Afrotechmods]

Yup! I do that all the time! It's like playing Atari 2600

[stormbytes]

Would you consider making a tutorial demonstrating the use of FG's (or PWM) in radio transmission/reception?

[Afrotechmods]

To be honest, I have never used an FG in either radio transmission or reception. Some FGs have an extra input that allow you to amplitude/frequency modulate the signals you are generating, but unless you have a REALLY expensive FG you are limited to carrier signals in the AM band (around 1Mhz). PWM is generally not used in radio although it's technically possible. I plan on doing some radio tutorials but they would be several months out as I've gotta cover more basic material first.

[stormbytes]

Ah, well... there's the rookie in me! Some basic tuts (especially a series!) would totally rock! I'm really glad to hear you've got it in the works. I'll be looking forward to watching and learning as I'm just getting started (late as it may be!)

[stormbytes]

Dude, you are HANDS DOWN my favorite source for electronics tutorials, on Youtube and elsewhere. PLEASE keep them coming. You explain things clearly and concisely. I watch pretty much all your stuff! :)

[poopmonsteh]

this is surprisingly sobering.

[freeman909]

great tutorial man....you rock!!!

[drverieevil]

This rocks

[robotkid249]

What kind of transistor is it?

[Afrotechmods]

Any NPN transistor or N channel mosfet would work for what I did in this video.

[runnningrage]

@Afrotechmods

I having problem geting NPN transistor to turn-on with

GF-8046 function generator i don't know why i can't get the transistor to turn on. I check the voltage and current output im getting voltage reading but no current at all. Afrotechmods did you using something before the transistor base to turn it on. If anyone can help here with advice on how to turn on transistor with funciton generator

[2acrmatthews]

Wow,

I totally love your tutorials! I think I just learned more in 15 minutes that I have in a month of reading. Your method of explaination is great. How bout tutorrials on the the uses of capacitors and resistors?

[mace1337]

Hahaha, you said doodie.

[Afrotechmods]

I was waiting for someone to say that!!!!

[MrKhalio]

thanks .nice job .more tutorials pls

[DJDonaL3000]

i like de way he says "function generators"... Top Buzzer...

[carbednotch]

Hi man thanks for the video I was on ebay and saw what it was but was not sure on its purpose. Can you answer one question which you did not address? Gating. What is GATING and which function generatior option is that going be?

[Afrotechmods]

Dunno! Anyone else got an idea?

[carbednotch]

I figured it out. Its just another name for duty and mark options.

[SSNK101]

Good one.

[ithnkurcute]

5* for you man! Really appreciate the tutorial.

[DragonTrew]

Awesome job mate! Really nice and objective explanation.

[blink182avaplus444]

thanks dude... :D

[busybjorn]

Compared to numerous pages of text describing the function generator this short clip explains it all in just 2:27m.
