6 months later and it still rocks!
By Mountmonty
Similar to other reviews, I spent a LOT of time researching before finally buying the SDS7102 scope. I've had it for 6 months now and can say that's I'm really happy with my purchase. I would recommend the EEVBlog forum review as it is quite good and covers most of the pros and cons of the scope.
A few things that I'd like to emphasize:
PROS
SIZE - This scope is very lightweight but doesn't feel cheap. There is enough heft to make it work the money!
SCREEN - The screen is really nice. Excellent colors and contrast. Easy to read. No glare.
VGA OUT - Ok, this is a bit superfluous, but it does work and it's useful to display and demo on a bigger screen or projector.
LAN INTERFACE - I just got this working the other day and it works great! Way more stable connection to the computer that the buggy USB. The only thing is that it's not documented anywhere in the manual! The trick? Read the help menu _on the scope itself_ to configure the IP addressing and ports.
SAMPLE DEPTH - 10M sample depth is really nice to capture a lot of data at a time for reviewing waveforms.
CONS
INTERFACE - As expected (and as with any other China Scopes) the user interface leaves a bit to be desired. Honestly, I've learned to think a bit more like the designers and you get the hang of it pretty quick. Just a few weird quirks with how to navigate menus.
INPUT RESPONSE - The knobs and screen have a small lag that's always there. Not a huge issue, but something I still notice. Not like a good old analog scope where it happens _as_ you turn the knob, rather here you can tell that the knob first tells the CPU to then change something on the screen, and it takes a split-second.
SOFTWARE - Also as expected, the computer software is buggy and annoying to use but it does the job and does allow scope captures (just for some reason the captures don't show the scales...I need to find out if that's a user-error issue).
UPDATE Dec 2012: The LAN function on this scope is awesome! I finally found the instructions for it in the help menus in the actual scope (not in the manual) and that tells you how to setup the LAN system to let you get much better and quicker captures which is less buggy than the USB.
Overall impression? Worth it. No doubt. I've very pleased with the scope's performance. If you're in the market for a good DSO for moderate to advanced project work and don't need the higher speed for baseband debugging, then this is the scope for you.

A good value scope for home use
By Ross Heitkamp
I don't have high demands for home use, but have been spoiled by using top of the line scopes from HP and Tektronix over the years, so I didn't have high hopes for getting a cheap unknown branded scope for home use. I am so far happily surprised!
The deep storage feature is great, but I was surprised that by default, the storage was set quite small. Also, it seems the deep storage is only available when stopped - like when doing single traces, so if you are triggering Normal, don't expect to be able to access all of it. Also, as you twist knobs to view that extended data, you will be affecting your next capture. This makes it rather inconvenient because you might take a trace, zoom in to look at an area, but then need to get back to your original settings before you can trigger again or you might not see the area you were just looking at. This is really a bug, because they have a "Zoom" menu for the display that should separate the controls and settings between the capture and the view, but they don't seem to be separated.
So far I have not had success with getting the computer control of the scope to work. I went through the setup and have tried a couple times to connect without luck. I will try again in more earnest when I am done with the current project.
When I couldn't remote connect, I did try out saving the display file and have used that. One thing to note is that saved waveforms are really just a save of what is shown on the screen. They cannot be zoomed or moved in any way - so it isn't a saved capture - just a saved picture. It would be nice to be able to name them, but since you can't, be sure to take notes of what you save and the settings so you can make sense of them.
Other things that I don't mention have all worked as expected, so that is why this gets 4 stars.

Owon SDS7102: meets expectations
By Circuit Guy
I have used many scopes over the years, many of them very high end (Agilent, Tek, LeCroy), so to some extent I am spoiled. My workhorse scope at work is an Agilent MSO8104A (1GHz input bandwidth and 4GS/sec).
I purchased this scope for use at home on side projects.
I had a Rigol 1052E, which worked well, and I didn't have any complaints with it. The Rigol was sold so I could buy this scope as a replacement.
Two things drew me to this scope.
First was the memory depth. 10M points is simply unheard of for a scope in this class. The memory depth comes in handy quite often.
Second was the display size. The Rigol had QVGA resolution while the Owon has 800 x 600. All other things being equal, a display upgrade by itself is worth a lot to me. It's always nice to have a better display, and see things more clearly.
The 30 minute you tube review on this scope was quite helpful, and overall I agree with it. There are a few things that are worth mentioning that the youtube review brought out. First is how the memory is used when using both channels. Another is the force needed to actuate the buttons, which is slightly too firm.
For firmware, I didn't mind the menu layout, and could pretty much navigate to what I needed without much fumbling around.
So why not 5 stars? I don't give anything 5 stars unless it really WOWs me. Overall this scope meets expectations, and has some nice features, especially for the price.
