content: Amazon are selling a Kiprim DS1202 120Mhz 1Gsa/s oscilloscope at a relatively low price of £160 including next day delivery.There are good reviews on Amazon but they are from people that have been asked to do the review. I can't find any background info on this manufacturer or reviews.Anyone have any experience or know anything about it? Is it a new entrant into the market with a good product at a competitive price point to get a foothold or a rebadge of another oscilloscope?

content: The Amazon page doesn’t list full specs but there is a link to a Dropbox account (!) with a .rar file, and in that are manuals and software. I’ve attached a snip of the spec sheet from the manual.It seems improbable to me that Kiprim have developed their own oscilloscope. The specs match almost identically the Owon SDS1102 or Hanmatek DOS1102. If so, it might be ok compared to a Fnirsi, for example, because it will have real time sampling across all the ranges and a bit more sensitivity (5mV/div).But what’s odd is that the front panel layout (buttons and dials) is completely different to the Owon/Hanmatek, although the quantity of buttons and dials is exactly the same. Even the BNC connectors are in a different place. If Owon are the OEM why would they bother to do a different hardware layout for a rebrand?The marketing one-upmanship on bandwidth is a comic detail. Owon = 100MHz. Hanmatek = 110MHz. Kiprim = 120MHz…. Who’s next?

content: That's cheaper than the adc.Kiprim does have a relatively complex power supply which seems to be unique and not a rebadge, so it could just be a new brand which did a little borrowing of the electronic design.

content: Quote from: Marco on July 06, 2022, 06:51:38 amIf you're thinking of the Kiprim DC310S, then it could be a rebadged OWON SPE series.Edit:This could be a (slightly) reworked Owon SDS1102:- same (rearranged) buttons and encoders- rotary knobs look identical- screen layout is the same- the back looks indentical

content: I posted a question on Amazon about the FFT. One review mentioned 12 bit ADC. That seems pretty unlikely but ?? Another review suggested discarding when it needs cal because its cheaper to dump and replace (which is quite true).I am interested in an audio FFT display that can replace my vintage Wavetek. This seems to have promise. If the reponses to my question aren't too negative I may get one from Amazon. If its not OK I will just return it.

content: Quote from: farouqtaj on July 05, 2022, 11:26:15 amI couldn't find a support site for it either.It's too bad. It'd make a good sacrificial scope for automotive use.Also, I couldn't find any mention the USB port being used for firmware updates. This makes the think that if there's a firmware bug I might be SOL.WoD

content: Quote from: 1audio on July 12, 2022, 03:48:45 amA scope with a genuine 12 bit ADC is likely to cost significantly more than that is being sold for. I'd be surprised if it's anything other than 8 bit.

content: Quote from: 1audio on July 12, 2022, 03:48:45 amI'd say "impossible".Quote from: 1audio on July 12, 2022, 03:48:45 amThat sounds like an ignorant review. DSOs don't really need "cal" - they can calibrate themselves by adjusting their offsets and scales automatically.Quote from: 1audio on July 12, 2022, 03:48:45 amI could be wrong but I think the FFT will be very primitive in this price range.That said, I own a crappy mini oscilloscope that has an awesome FFT.Overall: I wouldn't expect much from this. There's a lower bound to "DSOs that are worth owning".If Owon (or whoever make this) ever brings out a model that falls into that category then I'm sure EEVBLOG forums would know about itveryquickly. I always keep an open mind but it hasn't happened yet.

content: I don't know the specifics but people have been pointed to USB audio interfaces for audio work, which have much higher resolution and dynamic range (albeit lower sample rate) than general purpose DSOs. Then you use software on your computer to get the traces and FFT.

content: I have PC/soundcard spectrum analyzers and they are quite capable but for the same reason USB scopes are not great for troubleshooting PC spectrum analyzers are slow and clumsy for audio troubleshooting. The stand alone Wavetek 7530 in an old Tek 7403 has been the most useful. The other stuff comes out when I need deep analysis and there are really good tools but just not great for troubleshooting.I have a Siglent 1104 XE but its FFT is pretty clumsy for this stuff as well. And the two cheap scopes I have, have almost useless FFTs if you need real info.What got me interested was the "screenshot" with what looked like a real, useful FFT with markers etc. It might just be an artists conception however. . .

content: I design USB PC scopes for the very low end.Someone mentioned FFT.I struggled to find a good FFT routine for my pc software.The ones I was finding were very noisy.I did eventually find one that worked properly.My best scope is 20 mega samples which means about 1MHz top end.Fine for audio work but limiting for anything faster.I did find it very useful for DCC signalling work.Sell it for about £30.

content: Quote from: adam4521 on July 05, 2022, 10:56:22 pmThere's a Youtube video where the USB/PC capabilities are investigated and he discovers it's an Owon PDS 6000 series underneath.Owon haven't sold the PDS series for a time. It looks like Kiprim got a supply of the parts and have put them in their own case.

content: Quote from: robert.rozee on July 14, 2022, 01:05:44 pmAt least they're being honest!Normally I'd say "any oscilloscope is better than no oscilloscope!", here, but ... 5Mhz is a little bit low.

content: Quote from: Wim-nl on July 14, 2022, 10:53:28 amAgreed! The larger and much more detailed PeakTech 1404 manual is far superior to the Kiprim manual.I fired up a 26B and set the output at 100,000uv The Kiprim easily handles 120Mhz. It peters out somewhere between 200 and 260Mhz. I really didn't pay much attention to the exact numbers.This looks like it will make a good sacrificial automotive scope. Much better for it to get run over or dropped than one of the Teks or the Siglent.Also, it is capable of firmware upgrades via a USB thumb drive. All in all, so far, well worth the price.It figures that it would drop ten bucks AFTER I bought mine.WoD

content: Mine has started doing this after about 1.5 years of use...Voltage waveforms like awful, and it looks like some quantisation error or something, there's random steps in the waveform.

content: That behaviour is typical for datalines of the ADC becoming disconnected. Mostly likely a solder joint issue. From a teardown video it looks like the chips are QFP so with a bit of flux and a flat tip it should be possible to redo the solder joints. But check for dodgy joints with a magnifier first.
