The Tool That You NEED - DIY Function Generator - Part 1

Testing power supplies can be quite tedious if you don't have a dedicated tool to do so. Typically, you would use a wide selection of power resistors to accomplish this task. But there has to be an easier way... right?

Great tutorial! Also, thanks for posting the schematic and cide separately!!

[@t1d100]

Nice project. I look forward to part 2.

[@SineLab]

Coming soon!

PGA to control amplitude. in sig gen they use parallel DAC. Serial is 12x slower (120MHz clock to get 10MHz waveform)

[@igormorozov6801]

Looking forward to continuing.
At the moment, I am analyzing the scheme of commercial analog signature analyzer. There is the same task, from the DAC to make not only an amplified signal in voltage and current, but also a bipolar voltage for conducting test measurements

Thanks for watching! The next part should definitely help you.

Good overview! It's getting hard for DIY to compete with cheap digital function generators but it's always useful to know how they work. Consider turning of auto-focus on you camera for some shot though maybe.

[@SineLab]

Thanks for your suggestion.

[@SpeccyMan]

Consider using off instead of the incorrect of!

awesome vid

[@SineLab]

Thank you!

[@Scyth3934]

woohoo new video!

[@SineLab]

Enjoy! :)

Nerdy noise musicians use this hehe

[@thiesenf]

Damn it... I just wanted to hear some music but there's some random dude talking over the music...
*crickets*

Lose the DREADFUL BACKGROUND MUSIC......
No, I didn't watch it, because of your DREADFUL BACKGROUND MUSIC!
