FNIRSI-1013D "100MHz" tablet oscilloscope

[Fungus]

Seriously , updates for a thing that was made like a toy with big hardware limitations ...

Sure, why not?

[cliffyk]

I ordered one from amazon last evening--after reading through this entire thread--and as one poster said, $150 for a 2-channel 20 Mhz (maybe 40?) 7" touchscreen tablet scope isn't too bad. In looking at the signals I deal with (hobbyist electronics and automotive stuff) the 50 mv/div sensitivity is not really an issue.

After my experiences with the FNIRSI-5012H I did not expect it would/could meet the 100 MHz and 1Gs/s specs--too bad they have to just outright lie about these things, they'd get a lot more respect if they published the real specs.

I hope it triggers reasonably well on aperiodic bursts (which modern automobile control systems produce mostly), that was my deal breaker with the 5012, will get this one going back to Amazon as well.

It's marginal though when using a 10x probe as we do for most stuff.

That is so...

We shall see, the good news is that if it is not a useful tool for any reason (even if the novelty wears off and it's no longer "fun") it can go back to Amazon within 30 days--for the simple and indisputable fact that it does not meet the published specs....

[cliffyk]

Don't know if anyone is interested, however in digging around the web early this morning I did find a PDF file of the 1013-D User Manual (47.5 MB)--for what it's worth...

I love the "Solemn reminder" section, lead me to wonder if the fellow above who tested the rise time used the 10X mode?

That's like sending a 100MHz scope back to Amazon because it can't measure 500MHz properly. I just bought one of these scopes and whilst it's not perfect I do find that I use it when the other scopes are tied up. Because it is portable and easy on the battery it is a great portable scope I can throw in the car anytime. Much cheaper than buying a battery for the TDS3000 Hopefully they will offer some firmware upgrades and allow the auto triggering level detection to be switched on or off. Like Dave said it is essentially,limited to 20MHz but that is fine with me for a general purpose portable scope for measuring audio and power stuff

cheers

Not at all; it would be sending back an oscilloscope claimed (by the vendor via Amazon) to have a 100 MHz bandwidth, 1 Gs/s sample rate and <3 ns risetime:



that does not...

Nope, 500mV/div max sensitivity using a 10x probe is just inadequate for many requirements.

However for the remainder it is not, for example it would be entirely adequate for displaying the primary waveform of a contemporary "coil-on-plug" automotive ignition system:

this is the "triple-strike" firing pattern used on many modern cars at idle and lowish RPMs to ensure a clean burn


Or the PWM signal at an idle air control:

I just bought one too 

Even with all the lies, bugs and limitations, I find the concept to be excellent.
I sometimes need to "see something" in hard to reach places or when I am not in the lab.
When we just need to see if the clock signal is here or if we have our RS422 pairs at the right place, no need for the big 5000€ scope balanced on the crimping pliers.

The fact that we can increase the battery capacity is great, the big 7" screen is also great, no fan. I hesitated with a handled oscilloscope but I find them very expensive.
If I like the concept, I think it will lead me to buy a Micsig tablet oscilloscope but the small form factor of this little Fnirsi is very very nice.

If they make their code open source, they can sell millions, I think.
It need a small silicone protection and a more expensive 50 € model with real 500 MSa/s

OK from here on and based on Dave's review you can assume it is a 20 MHz scope. Still a very useful portable battery operated dual channel scope for $140 IMHO

If only...

I'm thinking the next generation of these could be awesome.

OK what has siglent got to offer with battery operated, dual channel, 7 inch 800x480 full color touch sensitive display etc ?? And not some iddy biddy 3 inch QVGA BS either !!

What you got ??

If the improvement over the original bar of soap scope is anything to go by then the next model could be a very serious proposition and this company whoever they may be could become a serious contender in the portable scope market

Also what a lot of others have overlooked with this scope is that because it is battery operated you can float the measurements above ground although I wouldn't recommend this when measuring mains equipment for safety reasons !!

The only reason I haven't bought one of these is that if I sell my Rigol DS1054Z and add $140 to the result (the cost of one of these) I'm in Micsig territory. A Micsig would make a lot more sense.

Plus Micsigs have a 4-channel option and I want 4-channel capability somewhere.

(OTOH I've got an Analog Discovery 2 on order so the 4-channel requirement might disappear when that arrives)

5.7" display and BW's to 200 MHz and some with 1000V CAT II isolation between channels, all 5 mV sensitivity AND a datasheet that can be trusted !

Nothing flash at all but they work as per their spec.

And you don't think 50 mV max sensitivity is piss poor ?

Just not battery operated or with 7 inch touch display.

Do you even bother reading the posts before replying? 

[jemangedeslolos]

Siglent SHS800 are battery powered.
This is the first model I looked at when I wanted a portable oscilloscope. But it is too big to be operated by hand, and too expensive as a "small portable bench scope".
The Micsig seems very interesting but too advanced for what I wanted to do.
There is also the Hantek 2C72 but the FNIRSI does just the right thing, 2 channels, large screen and large battery.

This thing cannot and should not be compared to the Siglent or Micsig offer.
And cannot and should not be used as a real scope or to replace a real oscilloscope.
It's just a cheap portable tool that allows you to take measurements very usefull in certain situations.

Yes and it's a hell of lot better than having no scope at all !!

For some time I have been looking for a Tek THS7xx scope at a reasonable price. Only monochrome and QVA but have proper isolation between channels but only 30k record depth The Tek THS3000 are way to exe but offer 4 channels and full color but still QVGA and 30k record depth. Or the Keysight U1620 which has 2M point record depth going for around $1000 USD if you are lucky to get all of the accessories. However this scope will do me for a while Hopefully we should see some firmware upgrades if people would stop bagging the crap out of it all of the time and instead offer some constructive criticism

I have a 1054z tied up doing I2C decoding so this scope becomes useful for the other measurements when I don't want to boot up the Tek TDS7054 all of the time !

I'm hoping the AD2 can take over the decoding duties.

[jemangedeslolos]

Yes it does and in real time

Hey, I just worked out how to turn off the auto triggering level. It's in the system menu  This scope just got a lot better
