In my opinion, an excellent oscilloscope for $ 70. Thank you for your detailed review
My pleasure!
@@TonyAlbus What about DSO1511E ?
@@Angelo0chek Have not tested, but i expect it to be more or less the same
Thanks for this review sure, it really helps
Thank you Samuel, This video was 2 years ago, and nowadays the ZOYI is a much better solution : go.tonyalbus.com/ZT702S
Have a look at my video here : ruclips.net/video/W89FpQM1T14/видео.html
I got one of these. I don't have a fantastic signal generator. The manual says that at high frequencies advice 5MHz, the 10x setting and 10x probe should be used. I wonder if your results would be better if this advice had been followed?
That has to do with slewrate, always use a 10x probe, but the thing is, on high frequencies you also need a 50 Ohm terminator. which also halves the voltage. you will get a slight better result with lower voltages. but don't expect much better
Holy aliasing artifacts Batman! So this is really a 1-1.5 MHz scope at best. The thing is for looking at lower frequency, well behaved waveforms. Why do FNIRSI feel the need to lie about the specifications of every product they make? For that reason alone I would never buy their stuff for my own use. Thanks for the insight Tony.
Thanks, yes a big disappointment.
Works great for setting amp gains and checking for signals on 8 bit electronics.
Thank you, yes indeed!
Nice review. For $70 it's not too bad. May be good for audio work. Thanks for sharing.
Hello Bill, For audio maybe..yes.. i did an OWON last week in my videos.. that one was double the price but double as good, so depends what you want/can spend also.. but is nice little thingy :)
There are way better scopes for $70 than this. Way better. For $10 more you can get the Zeeweii DSO3D12 that is dual channel, includes a DMM and will do an honest 120MHz with one channel enabled. FNIRSI must mean "dishonest junk" in some language and it's quickly getting that meaning in English too.
Is there a type that has two channels🤔
I think then the Owon or Hantek
Owon HDS272 go.tonyalbus.com/HDS272_Ali
Owon HDS272 go.tonyalbus.com/HDS272_BG
Hantek 2D72 go.tonyalbus.com/2D72_Ali
Hantek 2D72 go.tonyalbus.com/2D72_BG
better said 1 mhz not 100 ... to 2 megahertz there's nothing you can do with him ..😂
Yes as i said nice for audio
great vid
Thank you!
Can you measure the ac current from the socket?What is the maximum RMS voltage which you can measure?
According to the specs, (i have not tested, and i prob. will not), it can measure up-to 400 Volts on the 10x setting and 40 Volts on the 1x setting.
Hi! What is the minimum signal amplitude detected by the oscilloscope? Can it be used to repair pulse voltage converters?
Hi Victor, i checked the website it says 20 - 100 mV .. i did not test that myself.. i was not to much impressed, but i think it is okey for general lower frequency stuff.
@@TonyAlbus Thanks.
At 22:24 you say *"should have bought the 5012h and not this....."* but you don't say WHY ??
What's the reason the 5012h would have been better in any way ?
Hi CJ, you are correct, it was more based on my disapointment then practice, other reviews i have seen people seemed to be good with the 5012h and i was not about this one.. but its prob.. just as.. good/bad. depets also what you need it for, but the claim of 100 or 110 MHz is silly.
@@TonyAlbus Thanks for the response, and so fast too !
I'm looking for my first 'scope, just to diagnose some simple circuits, like a battery bank that i want to hook-up to a solar panel (see links). I don't know what simple circuits operate at when it comes to frequency, so i don't know what sampling rate, etc would suit me, whether up to 200Khz is fine, or 1-5Mhz is what i should aim for ?
I'm really wondering what the main differences are between the two 'scopes you mention ?

@@cjjuszczak The buy price of both is more or less the same, the specs also, they both perform nicely below 10Mhz , This 1C15 has as an extra, the calibration output the compensate the probe... and at the time i bought it, the firmware was newer then the 5012H , but they have now maybe also a newer version. for this price you can pick any but dont expect much above 10MHz .. so below they are fine.. i likes this one had a carry case aswel. as a first scope it nice... if you later want to spent more i can recomment Siglent SDS1202-X i have it and have not run to any limits yet and the quality is great and easy to operate. Tony
@@TonyAlbus Ok i think i have enough info to narrow down a purchase, thank you VERY much Tony, you've been very kind and helpful :)
Thank you and you are welcome! good luck with your buy :)
Very good.
Thank you! Cheers!
help me please ..
I recently bought this device..and it worked normal with me for several days..then suddenly the middle line disappeared and it does not measure anything..all buttons and commands are working except the middle line is not found..I did a calibration it gives me a message that the calibration failed (fail) .. I removed the battery and connected it again, but the same problem ..
what should I do?..
I hope you can respond and solve this problem with steps.
Hello Waleed, best thing to do i think is: contact seller trough sale platform, not directly.. when no response start dispute... good luck
is there cinas osciloscope you recommend?
Depends on the usage.. for LF Audio this is fine, for higher frequencies i prefer my Siglent SDS1202X-E oscilloscoop
Input circuit OPA695 datasheet SlewRate:4300V/μs . Question can I measure the SlewRate with the FNIRSI 1C15 .
i would not trust anything you measure with this toy. don’t waste your money on this.
@@TonyAlbus to measure in hi-fi audio equipment (10hz-25khz) ??? Thanks for answering
better go for the Owon 3 in 1 … if i had the choice again i would not buy this again. but if you need something in this price range… maybe. but remember you get what you pay for.
I see you buy things everyday. Can I come work for your company? I too want to buy as many TMI as like you sir. LOL.
Cute little scope but under power. May only work well in audio repairs.
Haha Thanks @yustech .. we all know... its buy, video, repair, sell.. buy other.. repeat :) buy, sell, repeat.. etc etc.
@@TonyAlbus I couldn't agree more. Keep the videos coming sir. Cheers.
Nice use of your microscope to show the internals 👍
I’m impressed it has an AUTO button
Yes it has, and it was needed on the older other models because the triggering was not that good:)
Your audio not clear to understand
Thanks, Yes older video, i have been strugling with audio for a wile, my new videos are much better
Very poor audio quality, can't listen to the end.
Thahks for your feedback.. the video is 2 years old, you will find the quality of the new videos better.
Thanks for wasting your money on this so I don't have to :-)
haha... thanks!
