A quick look at my new piece of gear - OWON 1022i USB scope - low end cheap tool, but it will be perfect for making videos when combined with the tablet I am using. Lots more videos about simple scoping coming up, so do come back for more, and remember to hit that bell for notifications!
Please subscribe for more random electronics related stuff, and remember to like and share the video!

WOW!!! My PC oscilloscope PeakTech P1290 (Made in Germany) is absolutely the same: appearance, instruction manual, operation, softwae, controls, all of these are the same as the Owon above. WHO STOLE FROM WHOM???

[@MCsCreations]

Really nice oscilloscope, man. Congrats on the new toy. 😀

[@randomtronic]

MC's Creations thanks!

[@ICStation2013]

Great!

[@maxiacosta1659]

Hi! Nice review, does the scope have the FFT module???

[@alexe610]

Thank you very much for your videos. I need an oscilloscope to check on the wiring in my full mux car ( CAN bus ). Which one of those oscilloscopes ( mentioned at 0:53 ) is suitable? Greeting from France.

[@randomtronic]

Hi, I am not an expert on canbus, but I think it runs a few MHz at most, in theory any of those should do for basic bug finding. But with a better and smarter (and mor expensive) scope you would get on the fly packet decoding and much higher res of the signal. I have never played with canbus though, so please do a bit more research before spending your money.

It works is all that matter to me

[@ruslankovtun6584]

how to open saved .cap file on computer for analysis?

[@davidforcey3809]

Do you know how to use this to look at 120v/60Hz electrical supply?

[@GeorgeJFW]

Great little review how has this held up and how is the software? I am.thinkibg about buying one. are those standards BNC connectors connectors? Thanks in advance

[@randomtronic]

Hi, BNCs are standard, and software is good, easy to use and intuitive. and no chinglish anywhere :) if the specs are right for you, this is worth every penny.

[@GeorgeJFW]

@@randomtronic thanks for the reply I ended up ordering one I was considering the hantek units but apparently there software it pretty complicated so I landed on the owon. Subbed

hola buen día, tengo un problema con el osciloscopio OWON, VDS10221 cada que intento abrir el programa se resetea solo, aparece el mensaje de inicializando pero luego es como si lo desconectara y no responde porbe utilizando otros controladores con ZADIG, y por el cable de datos parece estar en buen estado ya que en otra laptop, funciona de forma normal.

[@challchull3000]

does this owon vds 1022i better than intrustar isds205b ?

[@jeans.1328]

Which Signal generator are you using to generate that ECG signal? that cheap DDS Signal generator kit? THanks

[@randomtronic]

Daniu FY3224s

[@nicktohzyu]

does it have fourier transform view? it'd be great to see the FM signal that way

[@andrewwmacfadyen6958]

Yes it has FFT --- how good I don't know

[@ricardovargas5074]

Hola que opinan de estos tipos de ociloscopio

[@KerimKero1903]

Nice video. What’s the benefit of the isolated USB port ?

[@randomtronic]

Usb ports in computers are connected to mains earth. If you are then probing a device that is also mains earth referenced, you may accidentally create a path for short circuit thus blowing your DUT, PC and scope...

[@midwestmangos2452]

I got myself a vds1022 (not isolated) for christmas a while back, Ive heard its pretty easy to cut a couple lines and add in some cheap isolation circuitry to convert it to the 1022I version since they use the same board just populated with different components, but I can't find the website that described this process. Anyone heard about this before and if so do you know which components I need? I think it was a charge pump power isolator and an opto isolator array.

[@challchull3000]

jus try "usb isolator" on Aliexpres

[@redstarsrbija]

Why is the sine wave attenuated at those higher frequencies?

[@randomtronic]

It is due to bandwidth of the oscilloscope. Front end, ADC, everything really. But in general, front end is just not passing signal through to ADC, because it is beyond of what it can do, and then sampling of the ADC is too slow as well. Can be fixed with money. High frequency design is a whole different world compared to normal electronics, and usually price follows. I always think of RF (many GHz RF) is similar to Quantum Physics - not many people really comprehend what is actually going on... Lol

[@user-hk3ej4hk7m]

The Fourier transform of a pure sine wave is like a peak at its frequency (ignoring negative frequencies). If you consider your oscilloscope as a "system" that has an almost flat frequency response (gain 1 for that range) and then tapers of at frequencies higher than the operating range, you could very roughly model the oscilloscope as a low-pass filter, in this case with a cutoff frequency of ~25MHz. As mentioned a pure sine wave is basically a peak in the frequency spectrum, if you move that peak towards higher frequencies, the response in the frequency domain will be the same peak but scaled by the gain at that specific frequency. Because of this, it makes sense for the resulting wave to still be a sine, but with lower amplitude. However, for waves that are a mix of sines and cosines of different frequencies, square waves, sawtooth, triangles or whatever wave is not a pure sine, the higher frequency sinusoidal components get scaled down (the corners on a square wave), resulting on a deformed wave with smoother corners. I think I wrote the word "frequencies" like 20 times lmao This is how systems are usually analyzed, in terms of their frequency response, so it is really important to get the fundamentals of Fourier analysis right.

[@carlosvallejo4326]

Do you know if this scope is better than a Hantek 1008c?

[@randomtronic]

In my opinion, a physical scope will always be better than a USB one - for most use cases anyways.

[@andrewwmacfadyen6958]

Owon provide good logical keyboard shortcuts for all the common commands , the Owon software is a thousand times better than Hantek. Lack of an x20 Attenuator scale on the probe menu is the only downside.

Approx $110
