DISLIKED because of that stupid computer generated voice!! LEARN HOW TO TALK!!!

what are thsoe yellow red blue clips , called i need those

Using a oscilloscope to sell data

Gracias! Que emoción!

Video isn't needed. If you have a scope and you want to measure the ripple voltage, then you 1. Know how to connect the scope and adjust the timebase and vertical scale, 2. You decide where you want to measure, usually at the output of the PSU. These are things people decide for themselves, they don't need a video to educate them.

Good video for smps on measure ripples. Thank you

Why there's nothing in there 😂

HIlarious AI voice.

Great video. Thank you.

Please refer to "Measuring Ripple Voltage (caused by the switching action) in SMPS: A Practical Guide" (ruclips.net/video/aTpO2VT8qKo/видео.html) for measurement setup.

Please refer to "Switched Mode Power Supply (SMPS) Ripple Voltage" (ruclips.net/video/T-ufauARBvE/видео.html) for low frequency ripple voltage measurement.

Interesting !

It's exactly what I'm looking for, Now let's compare it to Arduino Nano, please 😂

atmega328p chip can produce it's system high frequency 50% pulse from CLKO pin (aka PORT B pin 0), by programming CKOUT fuse. so for 16 mhz crystal oscillator, it's 16 mhz pulse. to produce a more controlled pwm signal, you can use 8-bit timer/counter, check out Atmel-8271J-AVR- ATmega-Datasheet_11/2015 page 93, its max frequency should be pretty high, like 4 mhz

Please try in assembler and then compare results.

I like your oscilloscope....

Neat!

Thanks Sir

It would be intetesting to see the multimeter responce to the squate wave

Not sure what hese numbers represent: full loop cycle or a single pin set time. Also, what is the processor clock frequency? In any case, the numbers are not impressive. 8MHz loop at 72MHz clock yields 4 clocks to set/reset the pin +1 clock for the loop back. I was expecting a single clock performance.

Sir make video on spi decoder

its so funny to me how computers use crystals and vibrations to track time, so a rock that a bunch of really smart people engraved could communicate with us, in an electricity(aka lightning) based language that you need to learn for years, and we use said rocks to move information a stupidly large distance almost instantly, and calculate stuff that would take generations in a fraction of the time. it sounds like something from a medieval magic fantasy or a conspiracy theory

More explain this i2c working or decoding details each and every thing

Very useful. Thank you

Nice, cool ociloscope 😊

why 32.768khz instead of just 32,768hz? Also, what AI voice is this?

Neat! Now that you are done with the Rigol, can I pick it up?

no termination 50 Ohm ? ahi ahi !

please make video on spi decoder

This is still unsafe. By using an isolation transformer, your ground is floating. Best not to do that. Keep you scope grounded and use a differential probe.

Thanks

Is it safe to use high voltage on a breadboard?

It's usually much easier to thread a bit of magnet wire through the transformer. Then you're actually measuring the flux through the single loop.

Yeah. Men with diapers and flip flops built this with ropes & pulleys 🥴

When scope GND is connected with PE (earthing) like in this case, then You shouldnt use passive probe as You shown. Use differential probe instead.

Yep, looks like a healthy flyback transformer you've got there. This is a valid measurement method, but this is probing through capacitive coupling (dV/dt) not induction, as you don't have loop at the tip (e.g. clipping your ground lead to the probe tip).

Thank you

This is a "EMI measurement" by capacitance. Not by inductance. It will be better to use voltmeter to check this PSU instead.

Thanks for the effort but you lost me when you push the auto button. Have a nice journey :)

Sorry but seriously new to applied oscilloscope exercises. My old analog scope made by BK Precision had a user manual with great suggestions and instructions - like how to fix old CRT tvs and HiFi stereos. But no crystals. Should I just hook up the probe to either of the two pins from the crystal?

f103 used in st-link has quite weak crystal drivers. Especially for the 32768 one. So its output signal is more sine-like. The big guy has more powerful driver so it gives more square-like driving signal. Meanwhile input (mcu-wise) signals are almost same because they're determined more by crystals itself.

Your comparing a 30 Mhz Bandwidth Scope with a 200 Mhz Bandwidth Scope. Actually, you are doing this test all wrong.

Parabéns pelo vídeo , Muito obrigado por divulgar !!! Um maravilhoso sonho poder visitar a grande pirâmide !!! Muito obrigado , Sucesso sempre !!!

So, maybe you can show how it is done…

very interesting 👍thanks
