- The FNIRSI-1013D Tablet Oscilloscope - A Review #052
This Scope has a nice touch screen interface, reasonable performance for the price, and is potentially very ‘student friendly’ as it’s easily transported and has an internal power source.

How it's performance now
Hey guys how is it's xy mode? I have a cheap curve tracer I don't trust connecting to my good scopes but I want to test some germanium parts to build guitar pedals. And I want a non grounded scope for the bench in my garage to mess with fixing a short in my car.
Thank you for the correct presentation! I got one of these as a gift yesterday, it's better than reading the fine print manual. That's why I'm happy about the larger display. The rest are the Tektronix 465, TDS210, TDS224, LeCroy WaweAce 204 and this latest one 🤣 I've seen the smaller battery-powered oscilloscopes from my colleagues before, but their display was too small for my old eyes. It can really be used when we need a ground-independent measurement. I wish you many more successful performances and especially (this is the most important thing in our age) good health from Hungary!
Thanks for your interesting and informative video. I appreciate it. I have a very capable workbench with all of the goodies that one is likely to need. But I found myself often at my desk tinkering with an Arduino or such and needing to get eyes on some of the signals that I was working with. So I started to acquire a few instruments that I could grab handily and that didn't require a lot of real estate on the desk. I use this scope, a TinySA, a TinyVNA, a couple of small DMMs, and a couple of small signal generators that I can just use for those simple experiments. Super handy. A real time saver and convenience.
Just got one as a first scope to work on cars for injector signals etc. first video that was actually helpful as far as how to use it. Thanks!
Will it be good to check on ignition hard to find troubles? 2 ns??????
How do you like it so far ? I'm thinking about getting one myself for automotive use.
Finally, a reviewer that knows how to use the scope.
Thank you so much for the unbiased review! It helped me to decide whether should I buy it or go for Siglent or Rigols.
Very nice review! Enjoyed it! May be you'll find the following tests any interesting for the future videos: 1) replace probes with a straight coax from a signal generator to the scope to eliminate the probe issues, 2) measure raise/fall time of a square wave and derive bandwidth from there, 3) analyze a 20+ MHz square wave with FFT so it will be possible to estimate how far it can really see, and 4) feed an odd 50+ MHz function and compare it with a real 100 MHz scope. Thanks!
To address a couple of issues, yes it will display up to 100MHZ Repetitive wave. When viewing high speed digital, it is very clear, it is using integration on faster sweep speeds, so digital pulses rise and fall in amplitude at higher sweep speeds due to the integration of multiple passes. The vertical sensitivity is only 50mV, so it will not display low amplitude signals you are used to with scopes with 2mV per division sensitivity. My last beef is the lack of DC isolation with the USB port. Do not operate this scope connected to a computer and a piece of grounded equipment. The DC offset and damage to the USB port will result. I can no longer download screenshots from the scope with USB. I can still get photos by opening the case, poping out the micro SD card on the back of the PCB and copying the files.
Ok, so I just run some tests and I find pretty much the same thing with frequency, using the TinySA as the signal source.
So then, for fun, I connected it to the mains, 125VAC 60Hz.
I found that the sine wave had a bit of a dip at the top, right side! I thought, UH! OH!
To confirm what I was seeing, thinking it was due to a cheap scope, I connected my main scope (300 Mhz scope) to the mains and to my great surprise, the sine wave looked exactly the same!
I then decided to run tandem tests using my Siglent SDG 2080X signal generator and push through a 60Hz sine wave.
On both scopes, it was perfect.
I then moved up in frequency until the max of 80Mhz and again, the waveforms were solid.
So FOR ME, I can easily do 80Mhz on this FNIRSI-1013D scope.
That is great news for me.
I just thought that I'd share.
Thank you for a detailed and non-biased review. And it was very nice that you showed how to properly operate the device and what its (reasonable) limitations are. Well done indeed!
Nice, unbiased review! Best review I've seen on this scope! Well done!!!
I have one of these, I gave away my 4 ch 250Mhz scope and bought this simply because I do not use a scope very often and needed that space for my new 8Ghz spectrum analyzer. This little tablet is working fine for the couple times a year I need a scope to look at a low frequency signal. Scope fundamental: a 100Mhz scope is only linear to about 1/3rd of its stated BW. I tested the TinySA and it is pretty stable across the full frequency as tested with my 8ghz spectrum analyzer.
can the usb charger be inserted either way?
I've looked at a lot of TH-cam videos about the various 'cheap' shop devices and I always end up learning far more from yours than the others put together. You cover it all in very understandable terms. Thank you!! Two items, in particular, are this scope and the FY6900. You mentioned the TinySA and used it here. I have one of those too and haven't used it yet. I had no idea it had an output option. Off to see what you might have to say about that. Thanks again!! 73. Dave, AI7R
Dave, I appreciate the feedback, thank you!
This scope is OK, Ideal as a learning tool.
I still much prefer my Hantek DSO5102P, (review here th-cam.com/video/uSxSuNBnVEM/w-d-xo.html ) as I like the ability to tweak some of the 'deeper' settings. That said, I have gone up a steep learning curve this last year and am only now starting to appreciate the subtleties of the instrument. It would be nice to have equipment like W2AEW and Mr Carlsons Lab, but I could not justify the expenditure on a hobby.
Had a look at your QRZ page, well done on 50 years licenced!
73 de Bill, G1YQY (a comparatively recent licence at 35 years!).
For a student or hobbyist scope I think it is pretty good. Like you said this is portable and cheap. When I was in college I watched every penny.
Excellent review. I need a basic compact scope and this one is pretty impressive for such low $'s.
Really been enjoying your videos on these devices. Love your approach.
Great review and very well presented. This looks like a good option to visualize waveforms from my analog synthesizers
Might have to dig into the slush fund for one of these!
That’s very impressive especially the number of samples. I have been playing with a little Owon Scope that is 70mhz and 1.25gsa. It’s a shame they didn’t insulate the BNC connectors so it could be used in differential measurements. I think you should have done the bandwidth test using a correctly terminated cable in the scope. I suspect the scope may be performing better than you think. Really good review thanks for sharing. I am tempted to buy one but have scopes coming out my ears. You could build a fast square wave generator that would give you a good idea of the performance.
I'm a hobbyist and this will be great for the car ! Thanks.
Great student scope for an Electrical/Electronics Engineering or a Working Electronics Technician Oscilloscope, I wish it can do Vector Network Analyzer with a Smith Chart on the Screen on it. Thanks for this review.
Finally a good review in English, thanks for sharing
Eevblog has already ripped it apart th-cam.com/video/5iwtDwJlbWk/w-d-xo.html
@@martingerken7094 Thanks, I'm watching it now... Doesn't really matter very much now that I've purchased a Hantek Oscilloscope on Banggood this week, got myself the 70MHz scope that can be upgraded to 200MHz and they probably already did that upgrade as I understand from the recent reviews that people left on the website.
I think it's the best choice for me personally since it's my very first scope and it's the best bang for the buck to my knowledge.
@@RicardoPenders i've got the same Hantek.and i am.happy
@@martingerken7094 Well, thanks again for your answer, I've been looking at so many different scopes specs and people reviewing them here on TH-cam and to be honest it doesn't get any easier for me to make a choice so I've been thinking about it for months if not a year or so and I finally decided to get the 70MHz Hantek because Banggood offered me this particular scope for $219 this week which was an offer I couldn't refuse.
I wanted at least a bench top scope that looks and works like the professional ones and I think that 70MHz is more than enough for me as a total noob and actually my first ever scope, I almost bought the mobile scope the DS212, I think that one would also work out great for what I do but compared with the Hantek that only costs 60 dollar more and is way more professional with way more functionality and bandwidth that makes the choice easier.
But hearing it from you that you're happy with it makes me feel better with my purchase, still not 100% sure though.
It's because I have to pay it out of my own pocket and it's the most expensive item that I bought on Banggood which is risky on its own because of the way they are shipping it from China, that part I'm not so sure of but everything else has been delivered in working order so I'm probably good I hope.
@@martingerken7094 this review from Lockdown Electronics is much better than the one you mention.
Thanks for the great review. I wish Hantek would make a scope with this formfactor.
the best review I could find
Nice Bill...I considered an earlier version. Good to see they have recessed the BNC fittings now. Cheers 👍
Yes, I think your Hantek portable is much more versatile. I was pleasantly surprised by the screen on this one though.
Do you know why the cursor and messurements doesnt work if i do more time than 50ms/div?
@@rudimaier3679 if you get an answer would you let us know. I have the same sought of issue on my hand held touch screen scope. Trying to learn how to use it so any reply would be helpful thanks in advance Artie 👍
Thanks for the review, it is a very good explanation and test
I can’t wait till I get my first scope. I swear I’ll be up for days.
I just did. and yes. you will have a great time with it
@@sorrisousa Anticipation 🤔 so many things to probe. I’m going to gift myself one this Christmas. What model did you get and how much it set you back.
Thanks for sharing. Today is looking bright after all.
God Bless
Excellent video, thank you for sharing this overview.
Thanks, i am looking at it for a one-time auto diagnosis, so capture voltage drop behavior, so the big easy screen is ideal. I don't need great accuracy.
Hi, did you use it finally for car diagnosis? I'm looking for it to diagnose car too. Thank you.
Thanks a lot for this video, very well explained. Now i understand all the possibilities.
Thank you for the nice review, Mr. White.
My pleasure!
Great review. I love the way you concentrated on the user interface. I've seen other reviews that just talk about bandwidth measurements. I've been doing this stuff too long to try to use a "100 MHz scope" on something actually 100MHz.
The only thing I don't get is how such a tiny, tiny thing weights 100 pounds. It looks more like it should weigh about one pound. Pound and a half at the outside. The scope is about 4x12x18cm, or 864ml. Really heavy metals like gold or spent uranium weigh in at 19g/ml, so a scope made of solid spent uranium would weigh in at 16.4kg or 36 pounds.
Weigh's about a pound !!
Great review and walk-through of how to use it.
Well done. Bravo! Thank you very much.
Bill I like your review of the scope but with my big fingers the touchscreen seems very sensitive. I’ll keep playing with it to get comfortable but like you said I think I’m more interested in knobs and dials. So what I’ve previously said I hope you can hook me up with say something you would use as an entry level scope for an older guy also in lockdown in the US. The good part of the pandemic is I really enjoy learning electronics which in today’s world the knowledge is indispensable Also thanks for the PDF you sent me. 👍😊 Bill stay safe and well 👍
Artie,
I have owned a Hantek DSO5102P for over a year. This scope was IMHO excellent and taught me a great deal. It has the knobs you are craving!
There is a video here: th-cam.com/video/uSxSuNBnVEM/w-d-xo.html
Bill
@@LockdownElectronics Bill thank you much for replying. I’ve been learning the ADS1013D. It’s okay but I like the feel of the knob features. When learning with touch screen I find when you touch the screen it’s very easy to change setting you didn’t intend to change which makes it difficult to learn. I sure I’ll get use to its quirks but I’m definitely going to watch what you sent me. Thanks for sharing and helping me out. I seem to spend most of my time now trying to learn the electronics world. Very interesting. Bill I pick up quite a bit from your videos. They are very clear and easy to follow. Thanks again and stay safe and well during these crazy times. 👍😊
Artie, sorry it's taken a while to reply, have been away for a week diving the wrecks in Scapa Flow!
Thanks a lot for this well explained video. Now i know, i can buy it also
Great review Bill. I have also viewed the negative reviews on 1013D by EEVBlog and Learnelectronics (about 6 months prior to your review)who both claim (and demonstrated) the upper limit of the instruments they were reviewing was around 30MHz, but the machine you reviewed was ok to around 95MHz. I also noted some differences between the instruments. Your instrument had the input connectors recessed where as the instruments of the other 2 reviewers had the input connectors protruding out from the case. I also note that the instrument you reviewed was labelled "Tablet Oscilloscope" whereas the other 2 had the Fnirsi logo., which makes me wonder if Fnirsi had upgraded and improved their instrument in the time between the reviews. I'm actually looking to purchase a DSO and signal generator right now and the choice seems to be between the 1013D plus an external generator such as FY6900 which I note you have on your bench, and the Hantek SDSO2D15 with the built in AWG. Having used both companies offerings, do you have any thoughts on either solution?
Eric, well the tablet scope is ok, but it lacks the flexibility of rotary controls to make fine adjustments.
I had a Hantek DSO5102P, which was excellent for the money. I see that Hantek now do a bench scope with a built in signal generator. I have not tried one, but I would expect it to be equally good value based on my experience with the DSO5102P. The model numbers are DSO2D15 and DSO2D10.
Might be worth a look?
I liked your review..
I think people are often comparing scopes like this one or multimeter scopes to desktop devices like keysight and even more expensive
Couldn't agree more, I want something like this for measuring simple sensors for automotive diag this is ideal.
If I'm playing with electronics I'm at my bench.
Thank you for sharing, very informative.
I really disliked the cheap plastic fold-out stand. I was always getting glare from the scope angled towards the ceiling. I decided to modify my fold-out stand with a couple of small O-rings. I put the O-rings over the plastic hinge pins of the fold-out stand. This sort of worked, but when I installed a small piece of 4mm plastic on the other side of the stand, it wedged the hinge O-ring tighter and provided the friction that I was looking for. The change is like night and day. I used to have a flimsy stand and now I have a stand that stays in place where ever I position it. No more glare in my eyes.
Thanks for the very good review and for clearing up the bandwidth issues that have been reported. I have not seen information about the maximum vertical sensitivity and noise, can you comment on that?
Thumbs up. thumbs up, and more thumbs up for the video!
For the money its not terrible. I gad one given to me by a mechanic friend, non techy. He bought it for around 10-$20 from a place that sells random stuff, apparently from Amazon. This was brand new, never opened before. Now they're like $150. Its better than the Hantek USB scope. This one has selectable coupling ACDC. The hantek usb 6022 thing doesn't. The real disappointment to me from ths scope is that there is no input inversion. I really need that in my plans to use it on cars. The capacitive spark pickuo is a huge negative spike and its better if you can flip it. It doesn't seem to like it anyway. I don't believe this scope samples any faster than 40Mhz, but uses the frequency counter and some clever math and sample jittering to fabricate the waveforms. This ony works on repeating signals, grabbing bits and pieces here and there to put it back together. One shot stuff isnt going to work. Still irs far better than noyand the build quality seems nice. It doesn't look or feel like junk.
Very informative and impartial. Thank you. Like the channel too so I subed
Your video made purchased it and I love it
I like the idea of a tabletoscope. I've looked at the Micsig ones as well. They look pretty good if you're doing a lot of field work or automotive due to the portability but as hardware and performance they are still at the begining, a lot under entry level bench scopes.
Agreed, my bench scope is more flexible and I prefer to use controls rather then a touch screen. That said, the screen on this scope is very nice.
@@LockdownElectronics so what would you recommend as a solid scope?
The scope I was referring to in my reply is the Hantek DSO5102P.
I have upgraded to a 4 channel scope now, however for less than £175 (UK pounds) the Hantek was more than good enough as my first digital storage scope.
@@LockdownElectronics what 4ch scope are you using?
siglent.co.uk/product/siglent-sds1104x-e-super-phosphor-oscilloscope/
there are a lot of them in this price range with tiny screens. this looks like an almost normal size screen and i think would be a lot easier on the eyes!
It just knocks me out to see people trying to characterize a scope with some little, inexpensive Sig gen ! And, 50 ohms... I watched the EEV Blog review, and he constantly complained about everything, but it seemed that he had done absolutely zero pre-study... And, I have no idea what Sig gen he used, either... BTW, why not try turning on the RMS voltage measurement when trying the bandwidth? Is there any "fine" voltage setting, or just the "clicks"?
Bill my friend I have a question maybe you can help me with. I purchased the 1013D and I’m not to excited with the touch screen and also not being able to use measurements cursor in some modes. I’m sure it’s my lack of knowledge and the not so great instructions. I was wondering if you could steer me in the direction of a decent one with knobs for my requirements as a novice. Much appreciated I’m also building the kits you have built. Any info would be of great help. You stay safe and well Artie 👍
i received my scope just like yours yesterdat, only difference is the name on the panel is not tablet but fnirsi and it did not come with the charger. the connection for the probe is very near the corner and it is hard to twist the bnc connector to fit it in if u have large hands, they should have put it not very close to the recessed part. the thing that worries me is that it looks like this is a knock off, it does not carry the sticker stating the brand and model number or serial number at the back, you know how it is like in chinese instrument, but it's working for now don't know for how long
Here's hoping that it keeps on going!
For a bandwidth test you should have used a stable generator, You can't evaluate this scope properly by pushing that kind of a bit shity signal trhough it. Thank for the video.
To really show something you need to inject 100MHz, 5 cycles only and see what the display looks like. You can clearly see it working out abrupt frequency changes. That said it's a good portable scope for low frequency work. It's a good scope for a first scope if you're broke, but if you can swing $350, the Rigol 1054z is the best thing out there. All of the advertised specs are true. It really samples at 1Ghz and has better than advertised bandwidth.
Very good video. More fair and comprehensible than Dave's -eev- frantic and hysterical handling of the unit.
I can't stand that idiot's voice.
A comparison with a 100MHz bench scope would be interesting. It's at least C$220 here in Canada (shipped from China) - another C$100 gives you a real bench oscilloscope, so I'm not sure if it's worth the money here.
I will have a go at a scope comparison video at some point....
That's the problem with TH-cam "reviews", most of them are advertising. Comparison is not good for that. ..
a bench scope might be truer to its advertised specs. at least i would hope so
You could get a reasonable estimate of bandwidth by measuring rise time of a properly terminated square wave
I don't think the rise time on my function generator is fast enough to get a meaningful result, but it's worth a try.
Nice review, im owner pf such device for already quite some time, and it’s very rare cases when you’d need 100mhz bandwidth, using such device in automotive industry, however i have a question is anybody here managed to sync waveforms with pc/laptop? When it’s connected pc cannot recognize it… thats the only drawback i see for this device vs price point
Great review, has anyone tried the single shot mode on this scope? I haven't seen it used in any of the reviews for it...
I have a Hantek 6022BL and I'll be honest I don’t really know what I’m doing with it. I really must put some effort into trying to learn how to use it.
tjahh bang for buck, it seems decent.
but I really need those dials on a scope.. everything else its okay with touch, but scope that userinterface goes a long way,
my first scope was the DS212 from Miniware, and sure the build and design was nice, and looks like an apple Iphone when off but the interface was horrendous.
but have been skimmng the market for many years as I wanted an actual benchscope but also one that I couild easily put in a pack and that have a huge battery and one that I could take to the equipment and no vice versa.
but back in 2019 I took the plunge on a tablet scope with a bag that the vendor sells and where I can have the gear in. current clamp, all the gear, mouse, and all that jazz and I really likt eh briefcasebag and the ablelity to have all there since I dotn have a bench, so I need yo puy iy away when not used and its been solid since was around 350 euro with incl. shiping to Denmark and danish 25% VAT.. I could also purchase it from Batronix but was almost double the price... (Micsig STO1104C)
It got 28meg as I recall, and waveform capture rate between 100k to 95k in my testing.
but its suppresinly easy to record footage or connect to wireless projectors etc... as it is based in an Android OS, also liked that it had all these seriel protocols.
I reckon Micsig STO line is the best scope to balance a modern touch scope that can also function as a full fledge benchscope.when needed as you got the dials..
one thing Im using a lot is the colored intensity or heaptmap I reckon some vendors call it.

Also purchased that FY6900 to have alongside the scope and get acquainted and as a learning tool for supplying different waveforms and trying to make sense of it all and it's a nice DDS function generator for the price.. Bangg. sold the 60Mhz variant for around 70 USD from their EU store a year or two back.. and you get a lot for the money, even PC interface (windows).. though it's certainly not perfect their PC app, but it works and is quite nice you can run that FY6900 from the scopes USB 5v port. most of the time I don't use the AC socket on the FY6900.
Thank you alot for nice video ..please is any way to transform wave sampling as csv file to pc for further analysis with Matlab?
Awesome video.
Thank you
I just received mine and I don’t have any wave forms to change to. Has anyone seen this ?
thank you sir I was wondering how you change the time base
Very good!
so far i like your fresh open minded review... as per the chicken diner guy, he is really good but seems to be out for lunch on budget hobby stuff compared to $3K to $18K+ stuff...:/ thanks...:) PS it's nice to see the neat operating features as per what's under the hood....:]
Thank you for the feedback!
The 'Chicken dinner guy' ( :) ) really knows his stuff and I have got used to his style, the cheaper gear is fine for hobbyists and if it brings enjoyment, then as some might say 'winner, winner.....'!
I bought one of these but found my signals don’t look clean like yours. Mine look ripply, noisy. Even the self generated calibration signal was noisy.
I have one of these scopes. It is basically new as I have only used it 3 times for less than 1 hour. The 2 LED indicator lights are not described very good in the manual. Red light marked as power, which is good, but the green light says (over) and only comes on after unit has been plugged in a while. Is the green LED suppose to indicate battery charged?
I got this scope out to check a Heathkit RF generator I have, but has not been used in many years. When I turned the scope on it did not boot up. I hooked it up to charger for couple hours and still did not power on. Since you have one of these scopes I thought you might know what could be wrong
Can you hook up an amp clamp, in automotive use we now check ignition issues on primary side of coil by using amp clamp
Thank You So much.
I can't seem to see the audio riding on a 8mhz signal. Purpose is to measure modulation % on rf carrier. my other scopes show the correct wave form. Any ideas whats going on. OH, using correct probes and unit is calibrated. Please advise, i seem to be going crazy about this issue---no help from vendor, thank you
Trank you for this review, could you find info about FFT windw size of this osciloscope? Seller cannot provide this information and i do not have any info about it.
The FFT window is about 1/3 of the display width.
There is very little information on the FFT display, it's not the best FFT implementation by a long way.
Hello.
It could be used to check the electrical operation of a gasoline pump?.
Thankfully
Does anyone know why some of these scopes, in the lower left corner, have the word "TABLET" while others have the word, "FNIRSI" ??
While they seem to be the exact same unit, I'm just wondering if there's any significance?
Ideas?
I bought the same scope based on review. Sorry. It is NOT a 100MHz, 1Gsa/s scope, the rise time on 300ps signal shows 10ns (means ~25MHz bandwidth), the minimum timebase setting is 10ns/div, and it looks that all waveforms on
Is there a setting change the display language? I received one with Chinese language (which I can't understand) and would like to change it to English.
The Hanteck scopes have settings for multiple languages, hoping these might be the same; or alternatively, is it possible to update to English language firmware?
Would it be good enough for my electrical engineering years in university? I’m gonna be a student soon and won’t have much money, i don’t think i need a very expensive until i actually have a job where it’s needed and then justified to get a better one with salary money. But f now as a student this enough or do u know of any that is slightly better at same price range or even better at a lower price range. Thank you Sir
Awesome review! Thanks! This unit looks great for a beginner like myself. I am wondering - Does a signal generator like the one you have in connected in the video, perform the same duties as a PWM (Pulse width modulator) generator?
You have options. You can use an ESP32 to build a PWM generator or even buy an very inexpensive PWM generator.
Sir I have too.What is its maximum input?I mean how many volts can I check it for?
My charging light stays red "Power" stays all the time it is pugged in, the green light never comes on, which looks like it says "over" written next to it, will the green light come on when fully charged? Thanks for the help, has been pugged in for 2 hours with the charger they sent with it.
You ever hook this up to co.pate it with a higher end scope. And compare how accurate this is
can you connect it to a printer to print a waveform?....thank you
Hi,
There are 2 or more model of this oscilloscopes 1013D yeapook and FNIRSI and the price is different
What is the difference between the oscilloscopes?
Looking on the various web pages, they look very similar, presumably a re badge?
I got the same scope, no time base running, one of the horizontal bars won't go up and down, and intermittently it switches off. Who can fix it in UK? Maybe some kind soul could send me a copy of their firmware so I could try that, never know, mine could be corrupt. Need help please,
Appreciate the video. I have a question please. I've almost given up looking for something reasonably priced that will automatically calculate the total harmonic distortion from a whole home 220v generator. I have looked at several videos however that show how to calculate THD by measuring the RMS value of the respective harmonics using an FFT function on a scope...then manually making the calculation. Seems easy enough as long as you can easily identify and measure the specific harmonic values. Do you think this scope would have an accurate measurement of frequencies and RMS values of something in the 60 hz range and what i presume would be the say 1st 5 harmonics? Appreciate any thoughts.
The FFT on this scope is very minimalistic. I would not think it is possible to make measurements like you need.
Lockdown Electronics Appreciate that. Any thoughts on a relatively inexpensive scope that can do an fft on 60 hz and the respective harmonics?
Nice review. I'm looking for a scope that would be suitable for checking digital signals in a circuit clocked at 3Mhz. Would this be suitable do you think?
Yes 3MHz should be within its capabilities.
Hii and thanks for review
Can it be use on car repair?? have enough range?.
Could I run a test on my turntable if I am attempting to set up anti skate? I only ask because I am confused of how t his could be used to set up my turntable.
Is this capacitive or resistive touchscreen? I really hate cheap touchscreens but I'm almost sold. Thanks.
Apparently it's capacitive, see www.google.com/amp/s/www.cnx-software.com/2022/11/16/fnirsi-1013d-teardown-and-mini-review-a-portable-oscilloscope-based-on-allwinner-cpu-anlogic-fgpa/%3famp=1
A scope with actual control knobs and buttons is better IMHO
@@LockdownElectronics Thank you
@@LockdownElectronics I agree. While this is a cute scope for portable use, I won't be using it to replace my bench scope.
However, the devs of this scope really missed the mark by not having either a Bluetooth option or even a connector on the bottom where this could snap into an add-on that has buttons on it.
If Bluetooth, then the external button controller could be used at a distance.
good review~~~ !!!!
I'm basically scared off by it's 500mV/div sensitivity.
It seems fine for playing with power supplies or logic stuff, but absolutely not for low-signal circuits.
Agreed, 550mV/div on x10 setting, it will do 50mV/div on the x1 setting.
Hello, I want to buy this, but I don't know how to use it, what is the easiest way to learn it?
thanks
Great review, thankyou! I am trying to find out if this unit can compare two waveforms, from an amplifiers two channels, either visually overlapping to see how they differ, or via some difference analysis display. Is this possible?
Yes, you can compare two waveforms, see an example in this video:- th-cam.com/video/WMp7Vy1cKAs/w-d-xo.html
@@LockdownElectronics thankyou for the link to one of your other videos! I have watched it, and I probably did not word my question very well, I meant can the device overlay the two waveforms on top of each other visually so it's easy to see the shape differences? Or otherwise do a mathematical difference analysis and shoe that as a display line/wave ? I am needing something to measure and compare the two sides of a cathodyne phase inverter to balance them. (I am in North Yorks too :) )
A cathodyne eh? Nice!
Yes you can drag the waveforms up and down and overlay them for a visual comparison.
North Yorkshire is a big county! I am mid way between Catterick and Leyburn....
@@LockdownElectronics brilliant, that's great to know re dragging the forms, perfect!! I am south of you just north of York :)
отличный обзор. понравилось
what version of this tablet scope are u using cause i've seen some review of this type with the BNC connector sticking out but yours is flush-mounted which is a lot better, am planning to buy one but i like ur version with flush-mounted connectors
Yes the BNC sockets are recessed.
I had another look at the scope, there is no model number on the the box or the case. The only reference is during the start up screen where it says FNIRSI-1013D.
There is a link to the seller who sent it to me in the video description if that's any use.
Can this scope diagnose injectors and coil pacts on automotive testing ....
What's it's sensitivity? Is 500mV/div the best it can do?
nice
Can I use this scope for automotive sensors?
How does the oscilloscope work with banana plugs ?
What is minimum voltage sinus signal oscilloscope can show? Because mani people say, that he realy signal show from 1 volt!
Just checked mine, on x1 setting it shows 60mV OK.
Would i be able to rely on this scope to be accurate foor automotive engine sensors like cam and crank sensors and O2 sensors and so forth?
If their frequencies don't go over 30Mhz to 50Mhz.
While this scope can SUPPOSEDLY do 100Mhz, videos that have been done on that subject, with this scope, suggest that it's not great at 100Mhz, but just fine at 30-50 Ish.
