Thank you for the info, I'm 57 and just now learning, ultimately I want to repair flat screen TV. Thank you Element 14!

I haven't used a function generator but I have seen the sweep function used when testing audio amplifier circuits. 20hz to 20khz sine wave, to see if amplification is close to linear throughout the range.

I loved the explanation, and the reference to the graphing calculators.

I'll suggest this video to the students. They will learn something and enjoy your presentation.

I am pretty new to the world of ac electronics and this video helped a lot.

Thank you very much I wish somebody would make a video of how to use the function generator in it repair situation you know while repairing a circuit board how would you use it to diagnose a bad component

The generator sweep i use for filter test with a scope. You can do the same thing with a SA but that SA will require a track be more money and SA may have sensative inputs you dont want to blow up. For me the scope and generator are a better fit for when i need it. Im not at RF frequencies so it works.

Succinct and informative, I liked your presentation so much that I subscribed. Best wishes!

OK this is a important question to me I hope you read this. I am just now learning electronics in an old age out of boredom LOL. So I've been tinkering with Arduino and building my own simple circuits to make my life easier I've built a couple small projects that turned out nice etc. I do not have a scope but I'm in the market for one and I'm only gonna be able to afford a Chinese one someone told me hantec makes some that are also combo signal generators.

This is important to me because add an unrelated topic I have a case of galvanometers that are very expensive they were from a facility we shut down and they were gonna throw them out despite them being brand new but sarbanes Oxley dictates you have to get rid of that inventory if the product line is gone so it was going in the dumpster. I took like $50, 000 worth of I'm home but some of them are known to be bad in the box and they weren't marked well by the guy that used to tune them.

The driver boards are paired up with the galvanometers and I'm pretty sure I know how to make the adjustments but I wasn't sure if he used a signal generator to do this does that make sense to you at all? I believe he was using an oscilloscope and the signal generator to trim the square wave and get out the peaks. So does it sound like some a job for a signal generator?

Ok so I have no clue how to properly use a function generator. I did buy an inexpensive one on temu because I’d like to learn to use it. I’m wanting to learn about sound waves and build one of the sound/sand tables that makes the shapes depending on the frequency played. I want to know what frequencies match up with certain crop circles that haven’t been proven to be man made. That, and I think it’d be cool to make one and see the shapes in general. I know I don’t need one for that, but I’d like to know the specifics of the frequencies so I understand better. Do you have any suggestions for me 😊 a very clueless beginner. Have you ever built a table like that?

Is that a toaster oven in the background?

[Infinitesap]

Could you please make a video on how to use a fg? I have one and I'm insecure about how I can connect it to breadboard examples and scope with application of trigger in- and outputs from the fg or scope.
Please help

[icmontero]

Some function generator has a local view button, what is it for?

[XPFTP]

mod can be used in radio repair alignment of the radio.. audio filters i would think also ..

[JasonMontell]

I have Bill & Dave 3310b analog function generator with a range up to 100 kv.

[drumhead]

Can someone explain to me if it’s possible to listen to what you’re outputting if it’s within listening range??

MUSTOOL MDS8207 40MHz 200Msp Digital Storage Oscilloscope Multimeter Scopemeter

Anybody know if this digital multimeter/oscilloscope above would be good enough? Or do I need to buy the big dog $350 scope? Thanks

[sjn]

10:00 When does the toaster oven come in to play? 😀

[hoofheartedicemelted]

I am happy for them that they have 721 thousand subscribers, but unfortunately it means they talk at you instead of with you.

So many bench tools: LCR meters, multi-meter, ESR meters, bench PSU, oscilloscopes and not function generator- can't oscilloscopes have that built-in?:-)
