Wondering how OSCA02 and OSC2002 compare to Owon VDS1022I. Not by paper specs, but in real-world use, and when comparing only hardware properties and not the ones artificially boosted by a computer (having virtually unlimited memory).
(Prices with VAT in Europe).
Price-wise OSC2002 is about 125 EUR
OSCA02 and VDS1022I are both at about 100 EUR.
VDS1022 (non-I) is ~70 EUR.
Important: VDS1022I has USB isolation, which makes it more "fool-proof". OSCA02 / OSC2002 need a separate module for it, and it costs 40 EUR.
I see the old lotoins.com website is gone, the new address seems to be loto-ins.com. Not sure, why the branding was changed with that "-". The device images on AliExpress still show the old lotoins.com on them. And AliExpress Loto Instruments Store has more up-to-date product lists and images. loto-ins.com seems to be a bit abandoned in comparison.
I'm a hobbyist, working on occasional projects and repairs, and have no space to keep a proper bench scope on my table. Also, I have impaired vision, so an USB scope is a better choice for me because then I can zoom the image on the computer screen to make it easier for me to see.
A funny coincidence - jiangtao.lv ends with lv, which is a code for my country, Latvia
