Sadly, I can't get around noise at all, because I didn't win any Oscilloscope in the Wave and my China Scope has noise basically as a built in feature 😉
Changing the probe to x1 instead of x10 reduces its usable bandwidth significantly, this may or may not be an issue depending upon what you are doing, people need to check their probes specs to know how that will effect their measurements.
Hello, could you make a video about floor noise (in whiteboard maybe) about how affects "the number of quantization levels that are needed to display at that offset"?.. it has to deal and with the trriger level maybe which is changed when the waveform is out of the center? Thanks for all the nice presented tutorials.
For repetitive signals a good way to eliminate much of the internal oscilloscope noise is to use the average sample mode, results in very sharp traces. But be careful if you average over too many samples and the input signal is not repetitive, then the signal doesn't look like what you see.
I've used different scopes and you're right -- it is a hassle to measure around the vertical noise... Grrrr! as a firmware developer I occasionally work with the electronics at this level so the next time I'm facing this difficulty I'll try these tips to improve my measurements-- thanks for posting!
Some specific noise from probe and device under test can be eliminated by turning off unneeded equipment when sensitive measurements are taken.. ;) What's about noise from oscilloscope going back to probe and to the test device? Example, when testing transistor power amplifiers output cascade driver op.amp. with probe, especially non-inverting pin (but depends from schematic), in some cases, some oscilloscopes generates parasitic noises through probe, but amplifier doing his job and that noise goes to the speaker (very loud, because volume control in this situation is bypassed)..
Actually, the noise to signal ratio, N/S, goes up when you introduce more components (and noise) to your circuit measurements. The signal to noise ratio, S/N, goes DOWN.
Hand crank to start an electronic generator (Battery bank), that then powers an electric motors, that then charges it back and keeps the battery bank charged, keeping the cycle going with pleanty of extra power for other uses Have you even bothered trying your hand at free energy, instead of just dismissing it because it's the modern and accepted concencous?

Where is the link for the free Oscilloscope? !!!

Just shows how the chinese see an opening in the market and fill it !
Noise is just the universe getting angry when you try to look at things too closely.
Is that why my girlfriend is making noise for all the time?
I like it when she says "Now that you know about noise..." . Nice!

my god that was more information in 8 minutes than a 90 minute lecture
Erin is so cool! Yeah Keysight too
This was very informative and educational. Thank you.

Would using 1x rather than 10x add more load to the circuit? I guess it's a trade off at that point? (Another great video with a lot of TIL for me!)

shouldn't you say signal-to-noise ratio decreases @ 3:45 ?? cause there's more noise than before
Yep! Good catch. The noise goes up, the SNR goes down.
Hello, Erin
Very professional your tutorials.
Didn't she mean to say "down" instead of "up"? 3:46
Great video. Sibilance on her vocal recording is kicking, though. Otherwise, great work, Erin!
Looking for interesting tech videos - found interesting tech videos and new crush, too much of a good thing :D
gimme that keysight !

Where is this week's video ? :-( How about WTRF?

Hello, I love the video, gimme da scope
Don't forget that you lose bandwidth when you turn your probe to times one.
Eletroboom were are you
Please i wanna oscilloscope
Wow
//// no fourier,,,, detective,,,, no no
If the scope input is shorted, generally the FFT won't reveal any interference unless it's very strong.
