Reminds me of my Computer Engineering lab project from 2003. Simple digital oscilloscope made with GAL arrays, a parallel port, and Windows software. This looks like it has good enough sample resolution for the target purpose
Thanks Bob. Thanks for all the research to find a less expensive option for us nerds. Its really cool, because this will open up options for more people and inspire those to take the next step in their electronics hobby. - Also, this is a great device for anyone that needs to take measurements on-the-go, which is perfect for anyone working on Arcade systems on-site. Just take your laptop and this portable device and you are good-to-go.
Awesome! Not sure if you've covered it already Bob, but a video explaining how to take measurements on stuff inside a console with the probe would be great! (E.g. inputs/outputs of RGB bypass boards, chip pins etc.) I saw the other 2 videos you did with Ste, but those seemed to be mainly referencing the consoles video output. The more and more I see videos like this the more I wanna get a scope! I'll have to check this scope out!
More videos like this are coming. For the short term, it's still video signals...but I'll definitely be making other videos about procedures that require a scope and are gaming-related.
I own the same scope. Very good and fun to use. Better than the hantek one. Mostly All measurements options in the software like Volts, Freq,Pulse Time, FFT, Etc... 4 trigger methods including External Trigger. 40V max input on 10x (Probes are 1x -10x) *Some features:* Usb Powered. Two probes (2 Input Channels) Advanced features like Frequency Error Check & Export Live Data to Csv Format. Bug free Software. Auxiliary Channel for Output/Input. Fast Display of waves in Software. I baught one for 80$ from Aliexpress. The (I) Model is 400V Supported. You should buy that one of you want to do high voltage work.
The sample rate is wildly different between the scopes, but analog video signals are within the range for both. The Owon has 25 million samples for second (25 MS/s) where the Rigol has 500 million samples for second (500 MS/s). We use Lecroy scopes at work that have a max sample rate of 20 billion samples per second (20 GS/s). Our signals are much higher frequency and would be overkill for this application. Thanks for the review and for always looking out for us retro gamers.
RetroRGB Yep, I thought the video was great, just commenting on the technical reason that the plots looked smoother on the one than the other. You and Renée talked about it but the samples per second is the jargon used in the precision measurement world. Thanks again.
Great video, thank you. A PC (can be an old one) is a useful tool to have permanently situated on your workbench (to save clutter). You have instant access to device specifications and pinouts, and the ability to control devices such as a signal generator. Hell, you can even use it to have music while you work.
I just saw an oscilloscope on ebay and wondered what the hell it was for and so here i am.Still not sure what it is all about but something i read on a dunny door years ago came to mind.The rise and the fall of the lower left ball is equal to the angle of the dangle when the pull is constant.
RICHY MARK NORMAN The simplest explanation is that it shows what a typical meter doesn’t show: activity. Instead of showing what a measurement is at a given point in time, it shows what the measured value does over time: Up, down, on, off, reverse, negative, positive, etc. Measurements like that need to be plotted to make sense. Until modern times these were dedicated instruments with an embedded CRT (like an old tube TV).
Possibly, but older scopes need to be calibrated and that alone might cost more than this one. Also, I wanted to recommend something readily available.
When you are talking about detail on the Owan vs. Rygol, I noticed the Rygol is set to 500 MS/s and the Owan is at 100 MS/s, so of course the Rygol would resolve finer detail. According to Owan, the max sample rate is 100 MS/s, so it may be worth your time to go back and compare Rygol's 100 MS if you care.
Should have done the open-source DS212 from Banggood. Seriously! Their open-source TS80 and TS100 soldering irons are getting a lot of attention so there’s good reason to expect the DS212 to perform. Pretty please?
It's only 1MHz, which is why Bob stayed away from it. He wanted to investigate a device that supports the full analog bandwidth for standard definition video.
Great question. Standard definition video is typically bandlimited to just underneath 7MHz. The "rule of thumb" is to use an oscilloscope bandwidth which is 5x so you reduce the error to a couple percent (max). So in this case that would be 35MHz. However for non-design work, my opinion is that you can relax that to 3x so a 20MHz or 25MHz (like the OWON) would fit the bill. Anything less than that, and I think you would miss important details when looking at the signals.

Great video. I scored my cheap, but very nice, used scope by setting a Craigslist alert and waiting about a year.

Yup, I'm specifically recommending as a cheap way to test retro console and arcade voltages. Definitely not for "pro" use.

This video coincides exactly with my current interests based on your previous scope videos! Awesome!

Love this part of your Quick Shoot series!!!

Thanks Emmett,that makes sense.Cheers.
what about analog scopes, they can often be got for dirt cheap or even free.
Possibly, but older scopes need to be calibrated and that alone might cost more than this one. Also, I wanted to recommend something readily available.
all analog scopes have a calibration pin on face or side panel. You just touch it with your probe and adjust.
That's probe calibration, not the calibration of the scope itself.

Can this cheapie also do eye patterns for laser tuning?
Great video, thx bob

Ste Kulov Thanks! How many MHz does it need to be for that?
