content: I’m thinking of getting a portable (handheld) oscilloscope for playing with electronics in my car (eg Freematics OBD-II adapter).I came across the Owon HDS2202S, but then saw that there is (apparently?) a newer model.The HDS320S seems to have identical specs, except that the AWG goes up to 30 instead of 25 MHz.There were a couple of issues with the 2202 and I was wondering whether these had been addressed by the 320. But I haven’t been able to find a single review of (any of) the 300 series online.Hasn’t it been released yet? It appears to be for sale onhttps://www.owontechnology.eu/product/15559356/owon-hds320s-200mhz-2ch-handheld-oscilloscope?

content: I don't have one of these, but yes, it looks pretty similar except for the sampling rate and bandwidth.One small difference is that a few measurements have been added (RMS, Rise Time, Fall Time, +Width, -Width).The HDS200 series actually had no RMS measurement? Every Zeeweii "toyscope" has that.8k record length is not exactly overwhelming for this price today.It might be interesting to know if the higher performance affects the battery life.

content: Check HDS200 thead on EEVblog forum for more info. HDS* series has so many models and HW revisions (which is not known before test/disassembly) that focusing on any specific model makes little sense. HDS300 has few different specs, otherwise is identical to HDS200.RMS calculation is only on newer HDS* models, check specs in detail if you need that, because RMS won't be added with FW update.HDS2202S is a good choice and not a toy, with main limitation (compared to bench scopes) being limited UI (not enough buttons for all the functions). Specs are not a lie and usability is quite good for a scopemeter.

content: The 320S actually has the same sampling rate/bandwidth (1 GSps / 200 MHz) as the 2202S. But yes, 8k samples is a bit (very) measly.The niggles with the HDS2202S were the boot time (longer), temperature (higher) and battery life (shorter) than the HDS2102S.I suppose it’s safe enough to order the HDS320S… :-)

content: Bumping this to see if anyone has actually got their hands on one?I've been thinking about grabbing one for a while to throw in the tool bag but it's hard to tell if they even exist. There are a couple places claiming to sell them, but at wildly different prices so who knows what the deal is with these

content: Is the HDS320 even available to order via AliEx?it puzzles me that the specs are identical to the HDS2202.

content: I’m not so sure about chasing the maximum bandwidth model in this series. The HDS is a reasonable economic option at the entry, especially with the signal generator, but its overall usefulness is bounded by UI, the 8k record, not mitigated by having anything but basic edge trigger. I think the price is in the awkward spot, too close to oscilloscopes with dramatically better features, including Owon’s own new 12 bit ones that have hugely longer capture records, other triggers and decoding.

content: Quote from: YU2 on August 15, 2025, 06:40:23 pmNo, its a desktop format, but I think it can run on USB pack, like the Rigol. My point was that there might be other features, especially if looking at digital signals, that are worth considering for not much of a stretch in price vs. HDS320.

content: yep I have 2202S and it is extremely convenient for fast testing etc but I also would want a bit more goodies in it considering its price.But overall it works and few friends of mine after playing with it also got themselves same model and are pretty happy with it so one can not complain muchMy biggest problem with it is that they could make it with some low profile potentiometers cause that click click usage is not very appealing at some casesBut if one needs to just do auto and see what is in there then it is pretty OK. I also agree that some more points would be feasible on that price level.Perhaps in some not very distant future...

content: I assume the Owon HDS320S and HDS2202S have the same PCB design. The only difference is the software-level lock of its signal generator that HDS320S outputs at 30MHz and HDS2202S outputs at 25MHz and the rubber cover are in different colours.Consider HDS320S based on the reviews of HDS2202S. They both support SCPI commands via USB which can let you do some complicated tests such as bode plotting and etc..

content: I would say that I wished it would have a Max, Min and Ave readings on the DMM side of measurements, especially on AC and DC measurements.
