A few things that I'd like to emphasize:
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.
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.Read more ›
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.
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.
I did lots of Google searches and found a quite extensive 35min review of the 7102 on youtube. After viewing both positive and negative reviews I decided to order the item off Amazon Marketplace where I have a amazon store card account here.
I was especially nervous thinking the scope would come from overseas, but there was a US distributor from KY I think. I figured that if it was Amazon fulfilled, I would have adequate customer service if I ever had a problem with the scope.
The price point of $449.00 was great considering its a 1ch x 100mhz scope or 2ch x 50mhz scope. I got the box by UPS today and physically checked for obvious damage. There was none. Since Its been a long time since I operated an oscilloscope, I decided to read at least the basic operation portion of the manual. From reading the manual, I learned how to autoscale and adjust the probes.
I had to make sure that I plugged the IEC connector to the scope with more force than I wanted to to make sure it was plugged in. I spent about 5 minutes trying to figure out why it wouldn't turn on. That was fixed when I plugged in the cord very firmly into the scope.
My reasoning to purchase the $450 scope was simply to get a DSO (Digital Storage Oscilloscope) that will get me up and running when it comes to relearning DC and AC electronics. I figure that once I have self-study to refresh my skills, that I would buy a battery for the scope for field work. Then I would pick up a more proper scope such as Aligent 2000 series much later on.Read more ›
