Hi there
Has anybody own or used these Owen digital oscilloscopes with AVRs? I am planning to buy one mainly to use with projects involving AVRs.

says it has only 6K samples per channel. Way too few, I say, for the price.
For a lot less money, if you don’t mind being PC dependent for display, these are a great deal. I have one of the low-end ones; there are like 3 tiers on this same product, faster/more sample memory…

I’ve been happy withe '2090. I couldn’t rationalize buying a higher end model in the family. The software is good, not crashy like some China stuff.
I purchased from an odd-ball China distributor of things not all electronic and got a 30% lower price and 1/2 price shipping as compared to US and ebay sellers.
I took the plunge about 5 years ago and got the softDSP SDS-200A from circuit specialists:

For the features, you’ll have a really hard time beating the price. My only issue with it is that you do have to be somewhat careful with the inputs, especially if you like having your probes in 1x mode. Personally, I just leave them in 10x mode and let the software scale the measurements for me. If you do have the inputs in 1x mode and you hook it up to something significantly outside of the expected range, you could do some damage to it, from what I understand. That’s never happened to me, though … and it’s probably true of most any piece of test equipment.
Just today, I looked at bench oscilloscopes online and I still can’t get a bench scope with those features for less than what I paid for the above scope. I’ve even used it to troublshoot FM broadcast circuits and it works great.

There has to be a sweet spot for price/performance for standalone scopes like the Owen. Sure, I’d like a full featured Tek DSO, but the cost makes it a hard sell for hobby use. The PC scopes do provide better performance at the expense of needing a PC for processing and display. That’s not necessarily a bad thing, but I recently retired a 25+ year old Non-Linear Systems portable scope that served me very well in the field. I’m not sure how many laptops or desktops that I would go through over a 25 year period, and I fear that the required software may be incompatible in the future. Yes, I know that I can use VMs and there are other ways to protect my investment, but it is nice to have the device self-contained.
So, for me, I’d like to find an inexpensive self-contained portable scope that is suitable for audio and digital I/O signals. I’m debating if the extra $$$ is warranted between a 25 MHz scope and 60 MHz one. Anyone out there using the Owen scopes?

I paid $130 for my DS2090. Works very well.
I’ll plug it into a laptop or desktop and pocket the difference.
