Use the high-frequency grounding attachment for the scope probe. Use decoupling capacitors on Vcc of each oscillator.

Thanks Uncle Paul. You and Dave have pushed me to get a proper "budget" oscilloscope, the Loto scope you did a while back.

Hi Paul and many thanks for this comprehensive review that well complements "Kangaroo" Dave's one. I just discovered your channel a couple of weeks ago, and as a beginner in electronics (even though I'm the same age as you!) , it is a goldmine of knowledge for me, I really like the way you explain things, giving both enough background theory and sharing all practical tips you gained from years of experience! Anyway, as a 'noob would-be maker' guy tinkering with breadboards, Arduinos, ESPs, etc, and also being a fan of retrocomputing, I think I'm reaching a point where I need to get myself a scope, for experimenting and also for checking digital electronics components and some basic fault diagnogsis on old computers. I'm not really limited by budget but I'm trying to stay under the 200 mark and closer to the 150 mark if possible, and what limits me the most is actual lack of space in my home for this hobby, so I couldn't buy a full-size Siglent scope for instance without risking a divorce :-) Which is why I'm only looking at handheld/compact devices and try to stay away from 'blind' USB units that require a computer to operate. So, from your review it seems that even taking into account its shortcomings this FNIRSI 1013D would be fairly well suited to my 'profile'. Before seeing these videos, I kind of had my eyes set on the Hantek 2C42/2C72 models (advertised as 40MHz/70MHz units), but it seems this one is a better unit that seems to be easier to operate. SoI'd like to know if you knew the Hantek 2C42/2C72 family and had a chance to try them, and what would be your opinion on them and whether you would recommend them over this FNIRSI unit? I suspect that Hantek is much better known than FNIRSI in any case? The Hantek seems to have a greated accuracy for voltage by diision, being capable to get as low as 10mV/div, while this one is apparently stuck at something like 50mV/div (and therefore to 500 mV/div at 10X, really poor..) ?? Also I don't know which one of these models comes with the best probes, and lastly, how would I be able to calibrate the probes, could I just use an Arduino to generate a 1kHz square wave signal through an analog or digital pin ? (EDIT: just saw you actually did a couple of vids on this subject, 'Arduino and AD9833 Signal Generator', part 1 being at kzread.info/dash/bejne/i3ao0pqFprjUnMo.html) Apologies for this overly long comment and hoping you'll be able to give me some advice, and thanks again for your tutorials and reviews!

In all oscilloscopes the passband is declared at -3dB, so at 100 MHz a signal of 1 volt becomes about 0.7 volts, the important thing is that it does not distort the waveform.

A 100mhz oscilloscope has a passband at -3db, so 70mhz on a sine signal, a square wave is rich in harmonics, so suppose we see up to the 5th harmonic, it will be 14mhz, to see a square wave well from 100mhz, it takes a 500mhz oscilloscope.

not every KZreadr had a solid background in signals and systems most of them are hobbiest but that's okay

I just got the new version of the 1013d, and they made it a lot cleaner on the outside! The connectors and button are recessed so they don’t get snagged or bump into things, and the display cover seems much cleaner. There’s no massive bezel, it’s perfectly flat against the touchscreen

Saved me with this one man, have been stuck at a budget crossroads trying to decide whether or not to pickup one of these. Thanks!

Im glad to find this kind of channels

A perfect hobby scope for Arduino project builders like me!

This is much better than my Velleman scope. I like this table scope. Thank you for sharing this. Thumbs up.

In fact, this is not an issue, there is a rule of thumb that says: if you need to measure xHz in the DUT, you need a scope (and probes) with at least 5xHz capacity.

Awesome review, I like a lot of features on this scope.

I like it. It has a very nice clear and readable screen and portable. I don't usually need a 100 MHz scope might give it a try. Looking forward to seeing it in action. Thanks Paul.

Great vid! Was really looking for this exact situation, might wanna fix some watches

Cool review! Thank you! I bought it. Learning now

Good review, I learned lots about this little scope.

I have found the recommendation "Because the cable has a rather high capacity, the bandwidth in the 1/1 position is specified as only 5 MHz. If you need to measure signals with higher frequencies, you must use the probe in the 1/10 position." Have you switched the probe switch to 1/10 position before measuring the 100 MHz signal? Thanks.

Kangaroo Dave. LOL 😂 I love it! Thanks for showing us your new toy. 👏🏻👍

It really looks user friendly. That's a big plus!

To everyone saying this is junk, let me tell you it's not. Not everyone needs 100MHz bandwidth. For example, I bought one because I only need it to debug some MCU outputs and low frequency signals (500KHz MAX). This is fine, I don't want to spend 300$ in a baseline Rigol that I will never use up to it's full potential. Also, this scope is hackable, it runs Linux, which means anyone can write their own UI and software. That's what I'm planning to do. This will serve me both as a scope and as a learning tool. Sure I could get a Hantek, but the screen is smaller and it's not a touchscreen either.

This is going to be a popular oscilloscope regardless of it's specifications, it's affordable, it's portable and covers a lot of ground. I only work with audio equipment and in particular only analogue equipment, I have never needed to go beyond 30khz. The battery is easy to upgrade to a larger capacity if you need longer run time and it's not mains connected! Which catches some people off guard. Yeah it would be nice if it's specifications claimed were actually true but we already knew what was going to happen.

Hi @Iscle, I'm kind of a noob in electronics but therefore need a scope to get started and learn (I mainly do small things with breeadboards, Arduino, and also would like to use it for retrocomputing fault diagnosis & repair) and before this review I was tempted to go for a Hantek 2C42 or 2C72 (I want to stay around the 150 mark for budget). From this review it seems this FNIRSI 1013D is better than the Hantek 2C2/2C72 models, but I'd be glad to have your take on this as you seem knowledgeable on this matter!

@@laurentd9980 Hi Laurent! Well, this was my first oscilloscope. I was used to the ones in my university (HP and Tektronix, from around the year 2000) and this one is a bit less accurate but a lot better to use. I haven't had any problems since I got it while doing simple stuff (probing audio outputs, MCU outputs, I2C buses, etc). For Arduino this will work a treat (simmilarly to the hantek, except with a big screen, which is 100% recommended). Unless you're working with very high frequencies or with very low voltages (keep in mind this is just 8bits), then it will work just fine for your application. I haven't regretted buying it tbh...

Best review of this scope I've seen, thanks! I got one for looking at the waveforms of the 12 VDC to 120 VAC inverters in my RV, but while the freq is accurate, the PP voltage is not... it's saying it's in the KV range! Not sure what I'm doing wrong. But no worries, I didn't get it for measuring voltage.

Very good review and excellent counterpoint to Dave's as he pretty much hates any scope that's less than $5000 ;). He sees no real justification for cheap lab equipment. I still wouldn't pay over $100 for this scope, but it does appear to be a good value; I'm just impossible to please. It sounds in this video like you might been having some serious dental pain or recovery, so I hope that things are okay and that you're feeling well! I like Dave's reviews as he's a true critic and doesn't pretend that products are wonderful, but he also lacks the patience to learn how a UI works before condemning the product ;). Yes, it's fair to expect an intuitive interface, but he has a tendency to rant about a broken or missing feature for 10 minutes only to later realize that he'd been using it wrong. But your reviews are just as valuable as you offer a different perspective and don't expect a bargain, Chinese tablet scope to behave like a Rohde & Schwarz .

To see a 100 MHz square wave well, the oscilloscope must have a bandwidth of at least 1 GHz, because they will have to pass all the main harmonics, this applies to all cases, even expensive oscilloscopes !!!

Just received mine today. It's not like my tektronix storage scopes that I used at work, but it'll do for a hobbyist like me.

It does what it's supposed to do, especially given the cheap price. The bandwidth of 100 MHz is obtained by compensating the cable of the probe x10 and for that it is not sure that it can be reached without the right instruments to correctly perform the compensation of the cable (even assuming that the response in frequency of the probe x10 and its cable was a single pole low pass filter).

Excellent video! I have seen kangaroo Dave's video, I'm kangaroo Pete, it was great to see inside of it, I like the fact that the battery is easy to upgrade because 4 hours isn't enough! I'm sure that I'm not the only one who has spent more than 4 hours working on something and while you can charge it from a USB battery bank, I would rather know that I can leave it running all day and not have to worry about it turning off or to remember that I forgot to pack the battery backup! I only work with analogue audio equipment and I think that this would be more than enough, considering that it decoupled from AC mains makes it a bonus! The last portable oscilloscope that I purchased only had a 2.4 inch screen. I was considering getting one of those aluminium suitcases and fitting Batteries, raspberry pi and a 7 inch screen with a USB oscilloscope (I like the Lotto brand of USB oscilloscope) and basically install it into the case with the monitor in the lid so that it sits up when opened, but all in all, it would have cost me more make than the price of this unit. Sure the suitcase would be James bond cool but I would probably get arrested if I were to be pulled up by the police, I saw the reaction on the shop owners face when I should up with my DIY portable music player with speakers built into the lid of a little aluminium suitcase which was about 6 inch square, it had a very good headphone amplifier built in and I was there to test out some headphones, when I opened it and he saw the wires and the square lithium battery pack LoL, he shit himself. I hadn't had the opportunity to finish it off so that the battery and all the cables were hidden from view. I wish I had a GoPro running, it was a priceless moment that can't be repeated. Anyway, I couldn't make up my mind if I wanted this scope or not after watching Dave's video, I'm never going to get anywhere near 30Mhz and if I do! Then I clearly know that things are getting serious and I better start looking for a more capable scope, hopefully by then, these portable scopes would have slowed down the market for the bench oscilloscopes and they have become cheaper or better featured just to complete... Winner winner chicken dinner.

Got me one. I like it for my use. Just a cool visual in my music studio

Thanks for a review. Few questions: = Is the touch screen capacitive or resistive? = Is it glass or plastic (what about scratching)? = Your board with crystals does not contain bypass capacitors. In this case no surprise that you have poor high frequency sources. Could you put 0.1uF bypass cap directly on your high frequency crystals and repeat your tests? Or use a good generator for testing? = Could you measure rise time (after putting in capacitors)? Thanks!

I would have liked to see you superimpose channel A with Channel B on the same horizontal line (X axis) to observe phase differences like you do with a typical oscope. For example, have a simple RC filter on a circuit board and observe the phase difference from sine wave input to output. For me, this is a very important feature of an oscope.

Your explanation is perfect

Excellent presentation. Just convinced me to buy one. However 100MHz range is false, but do I really need ? Thank you for the movie.

I have Tested my FNIRSI with the supplied probes as also with Velleman's 100MHZ Probes. The original probes, allthough there is a label that they are for 100MHz, they can do the job only up to 30Mhz. I dont have an oscilator of 100MHz, but one which gives 66MHz. With Velleman's Probes this 66MHz are best seen.

I've noticed digital scopes sometimes need a larger signal before trigger will work.

OSC482 with an Android tablet might also be a good option. Have heard very positive words about OSC482 (and other Loto USB scopes), both for hardware and software (have to use HScope on Android though). Loto scopes seem to be of noticeably higher quality than Hantek and Owon models for similar prices.

Hii and thanks for the detailed review I want to buy for use on cars repairs. Is this oscilloscope enough fast, have enough bandwidth for car repair??? Thanks again

4:54 I have a strong suspicion that Dave never reads a manual before he starts his reviews. I had a unit he did a review on and complained about a 5th button that was unusable and properly from another version or design. On page 4 in the manual where there a clear explanation on this button and it covered most of the functions, Dave had hoped they would add in a later update:-)

OK, I know this scope isn't 100MHz bandwidth, however I wouldn't expect a genuine 100Mhz bandwidth scope to display 100MHz properly either. A 100MHz scope with 100MHz probes will have a system bandwidth just over 70MHz. See this for an explanation. community.keysight.com/community/keysight-blogs/oscilloscopes/blog/2016/09/01/what-is-oscilloscope-system-bandwidth-and-how-do-i-find-the-bandwidth-of-the-scope-probe

use good quality probes and check with 25Mhz or higher again .If the signals are same like before the check with other oscilloscope

So would this read automotive signals ok, abs sensors are like 32 hz i think, maf sensors are like 30 to 150 hz but i could be wrong about that

Sorry, but your test isn't valid. The "100MHz" spec on 'scopes is the highest frequency COMPONENT of a signal. A square wave consists of a fundamental & multiple odd harmonics. The accepted "rule of thumb" for looking at square waves is that the 'scope should have a frequency response out to "5 times the fundamental frequency". In this case, as they claim 100MHz bandwidth the highest square wave frequency would be around20 MHz.

How can you buy a scope that meets your requirements when the manufacturer is not going to be honest about bandwidth and sampling rate of the oscilloscopes they sell???

Can it still be used while charging connected to an isolation transformer? Just wondering if it still can be usable even if the battery dies. Thanks!

I have never owned a scope, so I may be misunderstanding something here. So feel free to educate me if I am. The thing is, I read that with all scopes, to get an accurate MHz reading, the scope's upper MHz limit should be five times higher than the output of what you are sampling. That would suggest that to measure a 100MHz device, you would need a scope rated to at least 500MHz. In your demo of this scope it read close to 30MHz with no issue. That actually exceeds the five times rule of thumb. Am I missing something?

I just received one, it's faulty, when I tap on left side, i get response from what's on the right and vice versa, to enter main menu I have to tap on the center-tight side, when I pass my finger on top to move the X pointer, the pointer moves the opposite direction! I think it has been initialized the wrong way, I'll wait for the battery to discharge completely, since there is no reset button to put it into factory default mode.....if this does not work I will send it back to Amazon...

The analog to digital converter can only do 20 Mhz per chanel (according to Dave).

Do you think serial decode can be done using USB? What can be read out using USB, anyway?

I like the touch interface a lot. Did you adjust probe impedance at all? Does your probe have a little screw for a variable cap? 10x versus 1x? You need the higher impedance at higher frequencies. How about running the oscillator output though a good logic driver than can handle it? The higher frequencies are not easy with op-amps, do you know what is on the inside? Maybe one of the Analog Devices all-in-one front ends or equivalent? It says 1 GSPS which should give fairly good looking 100MHz. As you said, just fine for all the usual measurements.

thanks! 100MHz is BW. which means gain is 0.707 compared with DC. Whether it can analysis 100MHz depends on design, 1G/s would be able to but this one doesn't

I think this max 100Mhz it is only for analog signals if you are using square signal then you have calculate how many odd harmonic signals you can see of that square wave - more harmonic nicer signal on display (scope). I guess this scope can work maybe with max10-15MHz of square signal.

Try using the scope without the probes. Use a BNC cable from a 100 MHz signal generator. And then use the probes to see if the bandwidth is limited by the probes themselves. I have seen bandwidth problems with cheap probes. Its worth a try.

Is there a way to use it to monitor power over extended time period?

After seeing your review that shows it for what it is; aimed at hobbyists with a low budget then it's fine for that. You pay for what you get in the end and as long as you don't expect too much then it's great for hobbyists. I realise that for professional use this is not worth even looking at. I think I've changed my mind again and will purchase one as a scope is not something I use often and I don't want to spend a lot of money on something that will be little used.

in theory you want to be sampling 5x the speed of the signal. So that limits it to 6mhz. You would also need to look at rise times etc.

seems to be a ton of these with about the same capabilities. an advantage of this one is bigger screen. probable disadvantage of no buttons is less precise control and more frustrating control

1014D-the real band turned out to be about 30 MNz. (The transition is not 3nS, as advertised, but 12 ÷ 14nS). On the 50 MHz meander, the signal turns into a "rotten" sine with a doubled amplitude. The manufacturer is cheating with the parameters, opened a dispute on the ALI, and won-seized a third of the cost for not fulfilling the characteristics. Comparison of the transitions FNIRSI and Tektronix, which he did for proof, lies here under the name "FNIRSI and Tektronix, this is how it should be done".

Why would you think this would measure 100Mhz signals? Nyquist theorem says we need to be 2x as fast as our signal and this still wouldn't give you any decent waveform.

@harryjohnson615

Because if the scope is sold as having an analogue bandwidth of 100Mhz then it ought to be able to display a 100Mhz sine wave and perhaps a 10Mhz square wave. Nyquist says you need to *sample* at twice the rate for faithful reproduction which isn't the same thing as bandwidth.

As for this model of scope, does anyone know how to tell the difference between the OFFICIAL FNIRSI made scope and a KNOCK OFF that looks exactly the same, down to the name label on the front? I'd like to pick up one of these, but I know that there are a lot of FAKE ones out there that have issues, especially at the higher frequencies. Any ideas? Oh, I forgot.... about the claims that this is a 100Mhz scope and this review, as well as other saying it's good up to about 30Mhz, makes me wonder if it's this "older" model that has this issue. I've seen reviews on the "newer" one (slicker bezel, screen is flat, no filets) and with those reviews, especially one that I saw today, he's able to get the scope to work up to 95Mhz. At 97Mhz and hitting auto, it doesn't even see the signal. But 95Mhz, I'd be ok with that for what I need to do. I would NOT be ok with just 30Mhz. Does anyone have the newer one and can confirm that they are getting close to 95Mhz or so? Also, I'm aware too that for the scope to see that high, it does require the probe to be set to x10. In the manual, apparently it says that one probe is only 5Mhz and the other is the 100Mhz, but that needs to be set to x10 and the scope must also be set to 10X, otherwise, higher frequencies won't work. I wonder too, now, if that's perhaps why some of these reviews aren't getting the bandwidth near 100Mhz... hmmmm.... Can anyone chime in on their real-world experience, please? 😁

Thank You!

This would see them dominating the hobby / amateur market and not be having to refund the purchase and shipping price because they bragged and over rated their products. In all cases the customer keeps the item and gets all their money back. Where are the bragging rights in this?

Dave is a snob. He is always over critical of any scope that doesn't cost over $4 thousand. I always wonder if he is so brilliant and perfect then why is he making YT videos.

Testing a 100 MHz oscilloscope with a 100 MHz probe and a 100 MHz square signal is not a professional solution at all. Instead, a sine of up to 100 MHz should be used, via a correctly terminated BNC cable. And even then, the amplitude will be only 70.7%. (-3dB)

Great review. I see that the Amazon price is already rising :)

Would this be a good scope for tuning a tesla coil?

Got mine today. Surely they are lying about sample rate. This device has also some serious limitations. Theres weird filtering of signals sometimes. This seems due to a limited number of samples it can take for one trigger combined with a sw filter which smoothens things out at the cost of a realistic view of the signal. A user must be aware of these limitations. It's a shame theres no trigger delay in trigger settings. That would really help in getting a decent view of periodic signals combined with the limited samples. All together it's what you can expect for this money. If you don't need more it's fine. If you want to display a 400 kHz I2C message for a few bytes it will fail short easily. If someone would take the effort of removing the filtering and showing the samples as is it would be better,
