You are really good at explaining things like this! 💯 This is interesting and entertaining but also valuable content for people wanting to learn about this. And even though I have worked with this stuff I still found the video really nice to watch, thanks!
@@KissAnalog Anytime! Your content is excellent. I would love to watch and comment much more of your videos, but unfortunately I got a nasty neurological disease (M.E.) that nowadays limits my thinking and energy levels quite a lot. But I certainly will watch and at least leave a like when have better times 🙂.
Thanks Scott! I didn't notice this before. I changed my camera rate to match my computer video at 25 fps. Before I had it at 24 fps and didn't see this. Crazy it made this much difference.
Thanks for the great video. I would not have guessed that the picoscope would produce a much better spectrum than the GW Instek if I hadn't seen this video. I work in sonar where we work mostly in the frequency domain, and the GW's two tone dynamic range of 50 dB would be considered unusable...
Thanks for this great feedback! I expected the Pico to have a lower noise floor, but I was surprised how much better the resolution bandwidth was and can be even better than what I showed.
That 12 bit res sure makes a difference, my 10 bit R&S doesn't compare. I think I'll pic up one of those, really cool! What's the class D module you're using? Also my thinking is that it's better if I take the preamp or buffer and feed the signal into it so the final bode or FFT gives me a better picture of the buffer / amp combo. I think I can fine tune my final result better.
Thanks for this feedback! The 12 bits - especially compared to 8 bits is huge;) I think once you get 12 bits then when I go to the 14 bit hires mode, I don't see a big difference. I think I'd have to be looking at something small to see the benefit of 14 bits. The 12 bits are noticeable though. I was curious so that was one of the big reasons I wanted to try the Pico.

Hey cool video. From the PICO website I've been trying to figure out what a few things mean. First thing is "Resolution enhancement to 12 bits" The scope I'm looking at says it's 8 bit but can go to 12 bit in enhanced mode. I wonder if it means the bandwidth is lower to make the vertical resolution higher? For FFT points it says "Selectable from 128 to half the available buffer memory in powers of 2" . Is that terrible? I'm still learning about the math functions on a scope.
Great questions Tron! I'm still learning too;) First, it is very typical that every bandwidth is divided in 2 for FFT. The basic 2 points per cycle is what it is. The bandwidth is limited because of vertical resolution. My Pico is 12 bit but can go even higher but is in 'hires' mode and starts to limit bandwidth. Unless you are spending $20k on a scope, then there is this tradeoff;) But, it really isn't that much of a big deal for most of us. Which model are you looking at?
@@KissAnalog 2205A MSO oscilloscope. I like that you can add a logic probe to it. Seems like a great scope for under 500 dollars. Only 25mhz but I don't really ever test anything that fast anyways.

I wish you the best and am happy to see you here;)
I'm really impressed 👏👌
Great explanation 💞
Thank you very much for new video 💝
Thanks so much - I appreciate you!
Sure eye-opener. Kinda says my GW is gonna have to have a contender at my workbench but the bank account says no way! (For now at least).
LOL That's awesome! I'll do some more videos to see how these scopes stack up;)
Ge rid of the color led back light because it beating with your camera frame rate causing strobing.

Great explanation! I’ve been tempted to buy a Pico 3406D.

Thanks for the video..I would like to see how to apply FFT to correct faults in amplifiers. Thank you
Thanks Fernando! I'll see what I can do;)
Hi Eddie, I really appreciate this awesome video and demonstration. ThankYou.
Glad you enjoyed it! Thank you!

Is class D a modified FM transmitter of sorts?
That's and interesting way to think about it;)
