New bench scope - Fnirsi 1014D, 7", 1GSa/s

[tunk]

New scope, Fnirsi 1014D:
- 7" screen
- 100MHz bandwith
- 1GSa/s sampling rate
- 240Kbit storage depth

Edit: The hardware specs looks identical to
the 1013D, so the real bandwith could be
20-30Mhz.

"Even if the encoder is completely broken, it will not affect the normal use of the oscilloscope at all"
"ads1014d still runs perfectly and operates correctly, getting rid of the limitation of the encoder's short life"

Are they actually admitting in writing that they're using very low quality encoders, and trying to overcome it with software... cheap way to save on such a basic interface feature. Basic encoders are not that expensive of a part.

Are they actually admitting in writing that they're using very low quality encoders, and trying to overcome it with software... cheap way to save a few pennies on such a basic interface feature. Basic encoders are not that expensive of a part.

At least they are honest. Encoders also fail on $30k scopes so nothing new here.

I think they are claiming to have taken debounce really seriously, which is something a lot of people should be doing and don't. YES LOGITECH, YOU ARE ONE OF THE PEOPLE I'M TALKING ABOUT. YOUR BLOODY MICE ARE A DISGRACE.

Encoders and other switches can be debounced in software much more easily than in hardware.

[nctnico]

But you'd still need a good signal from the encoder. If that isn't there then no amount of software can fix that.

Does this scope have a touch screen? Maybe they are just hinting that failing encoders don't matter because you don't need them.

Havent seen that brand in any store.

It's starting to show up at aliexpress for 170-190us$.
Fnirsi have also put a video on youtube:

BTW: I can't shake the feeling the styling has been inspired by Rigol

Certainly looks responsive.

Doesn't appear to have any serial decoders but could it be there's finally a 'scope worth owning for under $200?

Under 100 (97.50)  Euro in Taobao 

[Algoma]

I'm curious if they've used another Allwinner chip again as the applications processor. Certainly looks more responsive on the interface than previous efforts.

i have a sneaking suspicion the video may have been sped up in post-production. i could be wrong, but some of the hand movements and multiple presses of buttons seems unnaturally quick.

on the plus side, elements of the UI seem refreshingly new, other manufacturers could possibly uplift some of the design cues. and even if the scope only had a 'true' bandwidth of 20MHz, at the right price-point (sub-$100us) it could be a real winner. notice the use of an external plug-pack for power.


cheers,

The label on the back says:



So that's where the corners have been cut.

For $100 though? Much better than fumbling in the dark.

Yep. It looks to be double speed for most of the video, probably just to keep it short.

Youtube lets you play back at half speed if you want to see it for real. 

(still looks responsive)

And you don't think the 40V inputs isn't a significant design limitation ?
It's plain garbage and no wonder rf-loop was having a good laugh about these.

[nctnico]

It's plain garbage Siglent doesn't sell them and no wonder rf-loop was having a good laugh about these.

Fixed that for you!
Ofcourse these devices don't hold a candle against what you can buy in the $500 bracket. But for $100 you hardly can't go wrong and that is the price bracket Fnirsi seems to aim for. The cost is low enough that their devices aren't a waste of money. When I was a youngster a very simplistic analog hobbyist scope costed nearly 10 times this price.

[Fungus]

And you don't think the 40V inputs isn't a significant design limitation ?

Not really, no.

A 10x probe means you can measure 400V - more than enough for most hobbyists.

(I'm really starting to believe that all tautech ever does is measure ripple on power supplies...)

Here's a short look, including a photo of the PCB (using Google translate):

Specifying memory depth in bits is very odd and a good way to make numbers look bigger than they actually are. Assuming 8 bit and 2 channels, this equals about 15kSa/channel. Not very much. Judging from the linked PCB photos, they're probably only using the block RAM of whatever FPGA that is.

[Algoma]

Looks like the Allwinner F1C200s F1C100s and the FPGA looks like perhaps a rebranded GoWin FPGA. Just like the Hantek DSO2C10, but built even cheaper in so many ways.

Curious they put the firmware on the SD Card.. That makes it a bit too easy to modify.. not sure about the input jacks so far away from the frontend inputs.

First video review:

[joseph nicholas]

I think this scope is perfect for tech schools, and the high school lab.  It can be secured so as not to be stolen its cheap in case the students want to try to burn it and easily replaced.  For most hobbyist, the touch screen portable version would be much better.  You could take that out to the car or put it in a back pack.  Now do this with a spectrum analyser.

[UniSoft]

SoC Allwinner F1C100s
this is the same as 1013D... so, maximum 200Msps per channel.
