She's well trained at reading a script, but why doesn't Keysight use men for PR rolls like this? Obviously Keysight discriminates unfairly against men. For me this is insulting, and while shopping for a new oscilloscope I will be looking at other company's products.
Great video. I learned a lot about sampling rates. I already understood how important having a high sample counts but knew nothing about the interleaving. That's was very interesting and super easy to understand due to how you presented it. Thanks, well done, Barry
Thank you! I was reading "Computer Science Illuminated" and it brushed through this topic without sufficiently explaining it but you explained it in a way I understand.
If you had a choice of using 1 ADC at 1x sample rate versus doubling your sample rate by interleaving 2 ADCs, which measurement would be better? Is there a crossover point where the benefit of 2x the sample rate is gone when the time skew between the ADCs differs by some amount relative to the sample rate?
@1:15 - wait, what exactly is that "sampler" before the ADC ? I thought the ADC is the one responsible for sampling, the actual analog to digital conversion being the sampling process.
That would be the sample-hold device. It follows the input, keeping a tiny capacitor at the voltage it sees. When "hold" happens, the tiny capacitor stops following the input voltage and simply holds whatever voltage it has so the ADC can measure it. Most ADC designs cannot correctly encode a signal that changes voltage during the measurement process.
Amazing Explanation...Just a query..Can I say for using ADC on Raspberry Pi, (Sampling rate of ADC from manual)>(4*Highest Frequency in my measured signal)
Really a great video. I never thought about those insanely high Sa/S scopes and how they achieved that. Sometimes we have to live with a low end scope from "another vendor." LOL
You need to be clear on what you mean by resolution. You yourself stated the Nyquist theorem. Higher sampling rate will increase the resolution of the wave form up to the point of Nyquist frequency limit given a sampling rate. Your time resolution is NOT increased (assuming you are already at high enough sampling rate). Time resolution is determined solely by the bandwidth limit of the scope.
Discussing interleave distortion, with no mention of calibration and lab environment impact to instrument performance is leaving a gaping hole in the topic. It's easy to make a vendor's instrument crap the bed by forcing a self cal in one environment then moving it to another to do the measurement. Also some vendors suppress artifacts from their digitizers knowing they occur. It would also be nice to drop a note about waveform update rate and if it's continuous or in bursts, especially when you bring up "glitch" Otherwise, great vid.
also there is cost per glitch to capture small details. For high end R&D more is better "007" leading to very high end equipment or use lesser test equipment for hobby projects. 😎 thanks. looks like the: Keysight MSOS804A - Mixed Signal Oscilloscope (8 GHz / 4 Analog Channels / 16 Digital Channels) at TE Equipment is $101,466.00 on 11/12/2022 🥰
This is a good video don't get me wrong, but I don't understand the need to put constant music in the background. If i wanted that I could do it myself...

I do apologize about my not understand. Mix sounds with video is one of the hardest thing. To sync up. And depending an what the video is for. I've learn that you can't sync sound and video at different rates. It's hard but it's easy at the same time. Less is more and more is less. Ever wanted to know why sound and video goes out of sync sometimes after playing a long shoot. Well it's the sound recording and video formats are at different rates. Took me 30 odd years to work that out. And using cheap gear.

Good Job I wonder if the technicians really understand .... I've used both, and I prefer analog ....

These videos are the best advertising you could make. love it.
Thanks!

I LOVE IT! Great information hands down!
don't have enough money to buy Keysight oscilloscope but always watch your informative and fantastic video to learn something.So thank you :)
So clear! I love those videos! 😍
Fundamental RF concepts simplified & Well Presented !
So, what is the brand of the oscilloscope that doesn't synchronize its ADCs properly in the shown example?
From the screen it looks like a Tektronix
Awesome 🇧🇷😉👏👏👏👏 very cool video, subscribed, thank you girl
Hello, at 7:59 is there a mistake?... maybe want to say ("above" the fundamental 2.5GHz) instead of "below"?
A clear lecture and hypnotic lip movements, such a speech therapy!

3:06 There is a fault in these diagrams. A wave does not go backwards.

As always great presentation and explanation !
Ok keysight likes geeking out.Love these well explained vedio. Especially what the RF
nice explanation. thanks

Excellent explanation. Thank you so much!
3:00 It looks like some samples just time traveled😂
Exact ... unless it is a sample exposed as x-y instead of y-t.
I'm now dumber and not sure what I Just watched. I think I'm missing some info. So I'll stick to 48
LOOOOL

What a coincidence, i was reading about Nyquist sampling rate on my book :)
This is a good video don't get me wrong, but I don't understand the need to put constant music in the background. If i wanted that I could do it myself...
Thanks for the feedback!
**"Another vendor" wants to know your location**
They know where we at
How much price of this model oscilloscope?
Finally I got it. Thank you very much dear
Thank's for great topic.. :)
Yea, I will. When I get rich enough to have a scope where it matters!
Nice , thanks.
Nice and clear explanation.
Hence, why we keep an analog scope in the shop also...
To summit up you’re just saying that my song is forever unfixable🥺 thanks
I learn more from an attractive nerd than from anyone else. :) lol. Thank you!
Looks like she is wearing a Black Sun pendant.
Your website form rejects my legitimate business email address and personal email address. Fix it!
Weird! We haven't seen any trouble with it, can you try a different browser or try clearing your cache? What error message are you seeing?
This makes me want to run out and get a new scope!
I know, right? Just gotta remortgage the house first for the money...
impressive.
Let's go even further: Why even sample at all? Just make a guess :P
Nice

It's a tad ironic I think that a video about loss of signal is so overexposed.
Just introduce ABCD

Dude she wrote the script
@@KeysightLabs 10/10 clapback
Something from the Babylon Bee?
Girl is too happy in movie. Annoying. little suffer on her face, it will make video professional look
maybe she likes her job
Wtf R U on about.
It's not rocket science. Just double for -/+ and ad 400 for film.
