content: Hello dear people! I was roaming around aliexpress, like one does, looking for cheap equipment and I stumbled across this thing for ~$140 which is really cheap when considering what it's specs state(which I don't really believe after looking at the mini scope's review), looks very new tho and I haven't been able to find any videos or even posts of it anywhere.So I was wondering I'd come on here and ask you wonderful people if it might be worth buying, or if maybe someone has their hands on this thing. I don't have a scope in my lab yet and I was wondering what I should buy.I was looking at analog scopes but prices here are absolutely outrageous(150 euros for a used 1 channel 10mhz analog scope, give me a break...), I found some better ones like a 25MHz 2 channel Phillips for 100eu, but for that price, I'd rather use a Chinese USB o-scope with 60Mhz bandwidth, but even then I'd rather use a propper bench scope, so this scope might be something of value.Here's the listing:https://www.aliexpress.com/item/4000861098295.html?spm=a2g0o.productlist.0.0.22127b3doVRRR4&algo_pvid=edb11322-95b9-46ac-9a63-b8edb27f3c5b&algo_expid=edb11322-95b9-46ac-9a63-b8edb27f3c5b-13&btsid=0ab6fb8315872218024854861e5a0e&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

content: I can't find the exact FNIRSI-1013D 100MHz tablet oscilloscope, your link doesn't work.Dave's looked at theyellowFNIRSI-5012H 100MHz bandwidth 500MS/s.

This one should also be from the official firnis store on ali:https://www.aliexpress.com/item/4000934486311.html?spm=a2g0o.productlist.0.0.82921270tT6riy&algo_pvid=f6723bf1-94cf-4142-a575-b7c768967cb7&algo_expid=f6723bf1-94cf-4142-a575-b7c768967cb7-1&btsid=0ab6fb8815872260505105676ec577&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_And another one from another firnis store(?):https://www.aliexpress.com/item/4000904121391.html?spm=a2g0o.productlist.0.0.82921270tT6riy&algo_pvid=f6723bf1-94cf-4142-a575-b7c768967cb7&algo_expid=f6723bf1-94cf-4142-a575-b7c768967cb7-2&btsid=0ab6fb8815872260505105676ec577&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

content: The main hardware is probably the same garbage as the little one. If you want a tablet oscope don't waste your money and get a micsig.

content: Quote from: maginnovision on May 05, 2020, 07:10:42 pmFind out soon enough!MicSig is the much better choice if you need a portable scope. I just want to see if its the same old or whether they have actually progressed to something better, there is no pull apart/reviews on it I could find.

content: yeah definitely Micsig is better then this tab o'scope. But micsig is like a bench o'scope specially the sto1104c (with knobs On) looks like a fully featured bench o'scope. while this one could be used in field even if works reasonably around 20Mhz-ish.@wolfy007 let us know ur opinion when u get it..Finger crossed

content: Can you confirm the bandwidth? Price is very appealing for a small portable 2 channel scope.Looks like a few copycat / rebadged versions are making an appearance.https://au.banggood.com/DANIU-ADS1013D-2-Channels-100MHz-Band-Width-1GSa-or-s-Sampling-Rate-Oscilloscope-with-7-Inch-Color-TFT-LCD-Touch-Screen-p-1641865.html?cur_warehouse=CN

content: Original Poster's link worked for me.If they had a 4 channel version of this it would be the perfect cheap automotive scope. I don't have the need for anything mobile, but being battery operated would be awesome because then I would be isolated from mains. Even if it operates at half it's claimed bandwidth it would be worth it (to me).

content: Watch out for ESD even so!I'd be afraid to use such an obviously all solid state scope to measure spark plug timing, but I suppose there must be some way of doing it safeely. tapping off a logic level signal before it goes to the high voltage?You know, since your use is so specialized, I bet there is a way to do that for much less money. But of course it wouldn't look as cool as a tablet scope. If they can pull this off and its a decent product they deserve some kind of award. It would be such a great thing for experimenters.They need a better name. "FNIRSI" how does one pronounce that?Quote from: ResistorRob on May 12, 2020, 09:16:37 pm

content: Quote from: ResistorRob on May 12, 2020, 09:16:37 pmDon't mistake an oscilloscope like this with an oscilloscope suitable to use with mains! This oscilloscope has no protection against touching live parts at all so it is not suitable to use as a floating oscilloscope. You'll need to use a CAT rated differential probe anyway to probe anything connected to mains.

content: Quote from: hgjdwx on May 12, 2020, 02:05:46 amThe link now works for me but I still can't figure it's maximum/Div sensitivity. 50mV/Div makes me think they don't use any amplification on the inputs, which would make the high BW a bit easier.

content: Found this video about itHas a nice touch screen interface but not intensity graded or DPO so update rate is probably minimal. But still not a bad bit of kit for the money.
