content: Hi- First post here!I've been looking to get a cheap (<$100) scope, primarily as I fix old audio equipment and my very small workspace (and budget) precludes getting an old CRT scope so I was looking at cheap PC based scopes.There's plenty written on this site about the Hantek 6022BE and the OWON VDS1022 which would seem to be OK for my limited purposes (the Owon being the better model though). However, I came across a brand called Perytech out of Taiwan but I can find no independent reviews of their equipment. Their cheapest model (DSO-U2100) would fit my requirements at about $100 and the specs appear a bit better than the Owon 1022.Anyone know anything about this brand or can comment on the advertised specs?PS- I have no affiliation with any of these companies.

content: Hi, welcome to the forum.I hadn't heard of Perytech until you posted, they look interesting. Being based in Taiwan rather than the mainland is certainly a hopeful sign. Just some general observations based on the specs / website...- Decent sample rates for low cost USB devices. [Edit: Looking at their US distributor (they don't seem to have many worldwide) their 400Msps one at $235 may not be that competitive as you're getting closer to benchtop territory. Their 120Msps model drops to 60Msps for 2 channels compared to the Owon's 100Msps both channels too].- Sample memory is small at 8k samples, but still twice as much as the VDS1022 (4k) and much better than the 6022be (None!).- If it is managing those sample rates then it must have a reasonable amount of inteligence in the unit. ie. not a dumb streamer like the Hantek.- The UI looks pretty good (I'm not a fan of on-screen knobs and switches myself but they're not intrusive).- Triggering is a bit limited compared to the Owon, no slope, pulse etc. but hopefully, given the sample rates it is in-unit triggering rather than just in PC s/w (Hantek).- The measurement functionality looks good.- Protocol decoding is a definite enhancement compared to the others (only 2 channels of course).- Decent range of export formats, including Matlab. Labview compatibility too.- It looks as if you can stack multiple units to get more channels (not sure how well that would work with USB latencies etc).It looks as if someone needs to buy one and do a review / teardown.P.S.I see they do a 200Msps, 32 bit USB logic analyser too. It looks as if it does data stream compression like the Intronix Logicport. It has variable +/- input thresholds too.

content: I have had Owon VDS1022I about a year now and reasonably happy. Before that I had an elderly tek465 and there is no comparison on two counts, portability and being a DSO able to capture and store waveforms. If I was going to regret anything it would be not buying the 4 channel version. Triggering is spot on every time but that and the smallish capture memory are down to the implementation in an FPGA in the pod so it doesn't rely on the PC at all for triggering. One slight nuisance it will only trigger in auto above 50ms/div. Frankly you get what you pay for and for the price I couldn't do better, no way would I touch Hantek or the like toys.Noise level is ok, risetime pretty good (I do a lot of work on power mosfets), portability great, it goes up step ladders outside with me on debugging sessions, also happy on 5M of hefty USB extension despite having two USB plugs for PC (maybe thats a feature of the I version I have).
