FNIRSI-1013D "100MHz" tablet oscilloscope

[Valentin]

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:

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

Yes, I know he looked at that, that's what I mentioned in parenthesies.

your link doesn't work.

Weird. I clicked it and it worked, let me link another one. This one should also be from the official firnis store on ali:

And here are some images, there's a whole bunch more on the listing, wasn't bothered to screenshot them all:

[fkfaraz]

also interested in this tablet o'scope. does any body got hand on this o'scope???

Not seeing before.  Seems a new model.

It would be nice if that  BW is really 100MHz
unlike the others which more likely are 20MHz or so

Price would fit if 100MHz  otherwise just a crap
But a mobile bat operated 100MHz w/TFT touch ?

That is nice

I saw that, couldnt help myself and ordered one, I will let you know when I get it. I have to know if the XY mode is as good as the one video I saw or if its bullshit, I MUST KNOW....

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.

Find 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.

[maginnovision]

I expect a better mcu for handling the display and... Nothing else.

Maybe it'd be a decent platform for your own tablet project.

[fkfaraz]

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

[cdev]

Looks pretty nice for the price.

[Kosmic]

Frontend look similar to the FNIRSI-5012H but they added a FPGA.

[afm]

Reads 100 Mhz, or not?

[stefanh]

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.

This is the key:
4：Vertical sensitivity: 50 mV/div ~ 500 V/div

[ResistorRob]

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).

[cdev]

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?

allwinner F1C100S for main controller，it looks interesting

Don'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.

[Rhenium]

Hi!

Did anyone check if it was capable of 100Mhz? Or where its limit is?

[StillTrying]

4：Vertical sensitivity: 50 mV/div ~ 500 V/div

The 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.

[snoopy]

Found this video about it Has 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.

[wolfy007]

Mine hasnt come in yet with all this disrupted mail stuff, so I cant test anything yet, hopefully Kosmic will have further updates soon.

Sorry for the confusion, I didn't order one. Found those disassembly pictures on some Russian website.
