I would like to thank you all for your questions and participating in the channel. In this followup video I didn't mention names because of privacy issues, I didn't had an authorization from each one to mention it, but, I really appreciate the questions you made and I hope this video helps to answer some of the topics mentioned in the comments of the review video. Kudos for all of you and thank you for helping me with this channel! ❤

You can use this on a battery pack, save waveforms, and later connect it to a computer to retrieve these images?
You cannot save images to a thumb drive?
If the power is removed, are the saved images saved in the scope's memory?

[Warclock]

Any chance to go over FFT with this model. Thanks

[miss.wright]

Can this blow and suck at the same time ? Send signal and read at same time to calibrate tape recorder machine ?

[blugoose]

Will this oscilloscope measure voltage vs current for testing components on board?

[bjj]

How do you change the menu language from Chinese to English?

[robertholmin]

Thanks for fine the presentation. Is there a way to set the output voltage of the FNIRSI 1014D?

[mvee]

Hi does this have the ability to save trc waveforms or csv?

[spasovski]

Does the signal generator have amplitude adjustment?

[YasinSelim]

Hello,
Is there a material component measurement of the oscilloscope?
How to do this if it has this feature
Thank you,

[YasinSelim]

How can we make a component tester? Can you explain with a video or share a document?

[MrJonsi]

can you measure AC mains with this scope when connected to power bank? I know this will make the metal of the scope live due to floating ground, but if you just don't touch this will the buttons shock you?

0:55 might be usefull to say that you have have switched the probe before from x1 to x10 and also had adjusted the scope settings.

Beginners would not recognise that and results might look a bit different. So x10 is good in case you have such probe or switchable probe.

thanks for the video.. can i ask what value is C95 and C96 on the board for Vin of LED driver?

[Inavato]

How do you slow down the sample rate to see 100% modulation there is no rate knob?

[Tonyguitar-ibiza]

Cierto, no funciona el link de descarga del firmware, si pudieras compartir, seria maravilloso. Gracias.

[tonakkie]

Can you also power the siglent 1202x-E with a powerbank? Thnx

Hello Hugo, I really appreciated this YT review of the FNIRSI 1014D DSO. It was your candid review that tipped the scale in favor of purchasing this O'scope ~ 2 years ago. But I have a couple of questions that I've Googled until I'm blue in the face and can't quite get the answer I was hoping for. I'm simply trying to use this scope to assess the quality of our utility 120 VAC power vs. that when running on our back-up genny. I've read all the safety stuff and purchased a 100X probe. However, I cannot seem to calibrate/compensate this particular probe. All my other 1X/10X probes compensate just fine per your instructions on this video. I've reached out to FNIRSI too, and with all due respect, I am just told to read the user manual. Can you suggest what the issue might be? Btw, the 100X probe seems to work just fine and I can see my incoming utility signal perfectly. But when I try to calibrate it, it's just a straight line no matter what attenuation factor I try to use and trigger mode. I'm thinking that this probe attenuates so much that there's not enough output from the DSO's built-in function generator for the scope to trigger on. Your thoughts please!

Also, I was hoping to get a rough idea of the THD of my utility vs. generator via the FFT functionality. I think you nailed it though in your FNIRSI's FFT is basically there just for "boasting/advertising" rights and not to be used for diagnostic purposes. What good is an FFT if it doesn't have the attendant dB vs Hz levels.

Btw, I'm just an old retired NVH ME and when it comes to electronics/electrical stuff, all I know is NOT to stick a fork into the electrical outlet!!! :) Thanks again for your helpful YT video on this scope. All the best! John, aka NutDriver

Is there a single shot mode for this scope?

[fwblack]

Thanks for a great review. Does the Rigol DS1102Z-E have isolated input grounds? The FNIRSI 1014D does not and that can be a problem.
