I am just adding this comment, as I noted that u were sort of mistreated by a person who commented here in another language. First don't get bogged down by such ppl and the ppl who don't appreciate ur good work. If u have a brain of inventor, then one of the biggest blessings is not to have ears. Inventors and innovators are blessed ppl. As their sense of achievement and success and happiness is defined away from the society that is involved in petty issues. Second, since I have spent a very long time in electronics. I can tell u that a good scope is definitely an asset. But u don't really need to be desperate at getting very high end or the best. In fact as u go up, u realize that their utility is not as much as u thought initially. To give u an example. It would be idiotic if u imagine or try to work at radio frequency circuits of even 100 MHz with say a 200 or even 300 MHz scope. U don't !. To work in that domain the more useful things are signal generators, rf mixers, rf detectors, and rf log amplifiers / detectors and frequency counters, and filters. A scope is almost useless in that domain. So don't make the mistake as I did, in chasing the best bndwidth/price ratio with high bandwidth scope. U will drain ur valuable dollars for very little gain. On the other hand I have to admit that high bandwidth scopes are really a marvel of Engineering and really fun to work with. But the valuable lesson in the process is that nothing is so accurate and certain in high speed. The effects of inductance introduced by the ground clip of the probes alone are enough to mislead u like hell. Third: I never mean to undermine that u are a qualified engineer. But believe it or not. Academics have unreasonable level of disconnection from reality. And it often takes decades to learn that. It would be very good if communicating with ppl in the relevant community saves ur time on the learning curve and makes it short, easy and enjoyable at the same time. Wise ppl learn from the experiences of other ppl.
I really appreciate the kind words. I know that the internet is full of people who can be total jerks. I think that a lot of people didn’t get the fact that I was on a very tight budget when I bought this scope and I’ve never had a scope before so it was hard to find a good option that fit into my price range. This scope I think is plenty capable for what I do. If I need higher end equipment my university has Keysight 2000x series scopes that I can use. My university is also less that 10 miles from Keysight’s headquarters in Santa Rose CA. Keysight has donated all that equipment to the school and they have someone on campus 3 days a week that I could talk to if I needed to borrow an even higher end scope than the university has. I think my main point is that the scope suits my needs and if I need access to higher end equipment I can get it. Another point that a lot of people have pointed out is the this scope can’t do it’s full 100mHz claim, but I’ve noticed that everyone who has tested that has clearly not read the manual, because it says clearly in the manual that in order to get the full 100mHz bandwidth you have to use the probe in 10x attenuation not 1x attenuation.
I have 3 of these oscilloscopes and I had to repair one of them and since I couldn't find a schematic anywhere, I had to create it myself in the EAGLE program. It took me a whole month to put it all together. So I found 3 errors in the oscilloscope, in the play of low-voltage devices and one in the power supply. That's why he says I have the scheme.
Yeah I’ve had to do a few repairs myself, the horizontal scale rotary encoder locked up so I had to desolder that and lube it up again. And I blew the front end on both channels and I found the culprit was a tiny 10 ohm surface mount resistor I managed to grab a replacement off a donor board and I soldered one in place on both of them. It was not easy to solder by hand but I did it. If you don’t mind, could you send me the schematic? It would be fantastic to have for troubleshooting later down the road if I run into other issues.
@@deanhedin1615 If I remember correctly I think it’s 2 volts peak to peak and unfortunately there’s no settings to change the amplitude. If you need more then 2 volts peak to peak you have to amplify it.
I have another vid on my channel showing that. Although I removed the batteries and put in an internal power supply so that I can either run it off of USB or Mains power. I also added a wire to the probe grounds that goes through 220k resistor to mains ground so that it reduces noise and has an actual mains reference
FFT allows you to see the waveform you are looking at in frequency domain, and it can be really useful for finding certain frequencies inside the waveform you are measuring. Unfortunately it’s pretty much useless on this scope because there’s no way to use the cursors to find the actual frequency in the FFT waveform.
I like your bench. Its just like mine. I am a poor retired school teacher. This scope is confusing. I like mybTek453 better right now. Dies the power brick come with it?
Yes a power brick comes with it but it uses as normal USB-A power brick. I’ve made some modifications to it though, I added an internal power supply so that I can plug it in with USB or a standard IEC power cable.
If you want something extremely basic and you are on a tight budget I’d recommend this scope. If you have $400 to spend I’d highly recommend a Rigol 4 channel scope. I think that’s the best bang for your buck in that price range. But if you can only spend about $200 the the FNIRSI 1014D is a good option.
That is actually very simple, there are two ways to do it. You can either use a current clamp, which you can buy for under $100. Or you can put a current shunt resistor in series with your circuit and measure the voltage across it. I recommend either 1 ohm or 10 ohms.
If you have $400 US to spend I recommend getting a Rigol digital storage scope. If you are on a very tight budget this scope is the only scope on the market that is a 2 channel lab style format scope with a built in function generator for under $200 US. If you are looking for a lab style scope that you can run off of a battery then this is also a great option. I would really only recommend this scope if you are on an extremely tight budget.
There is a person on eBay selling his fir $130 , what he paid for it. Its a week old and he doesn’t like it. Claims to be an old school tech who dislikes the menu concepts of control.
This oscilloscope is probably fine for many tasks, but it does not meet its 1G Sample/s or 100MHz specifications. For more information, watch the videos on learnelectronics (both parts) or Kerry Wong. (Spoiler alert: it samples at 200 M Samples/s and its bandwidth is more like 30MHz.) For about the same price, I would consider the Hantek DSO2C10 scope, which is hackable to enable its function generator and raise its bandwidth. You might also consider the KiPRiM DS1202, which learnelectronics recently reviewed.
200MSa/S. That must be total/shared? Honestly, it's more than I expected. Still, it's too much when the 1054z is $350. It actually meets its claims though. My biggest hate is that they lie about bandwidth and sample rate. Just tell the truth FNIRSI.
This is a good scope for repairs on audio. I don't have one, but like it a lot. I only have a DSO150, and have designed pre and main amplifiers with it. The 1014d has a basic FFT, but you can use it to measure audio distortion with a pre created WAV file. Yes, you can get better, BUT it costs more money. Enjoy your scope, it's a good scope if you are a casual hobbyist. Kerry Wong and his 10 foot pole can shove it.
Its mostly a useless scope. Very over specified. There are a few positives though. 1- Its supposed to be very reliable. There is a touch screen version. And that means it will not have less reliability of mechanical controls. This version is boasted with the claim that it is with a special software that can handle a failing rotary encoder. Well that is yet to be seen. As this normally takes a few years to happen. 2- Its a low power consumption scope. It can run even with a decent phone charger. Beaides the above the greatest draw back among the drawbacks is bandwidth. It no good beyond 30 MHz. The 1 GSPS claim is obviously a plain lie. Its either 100 MSPS or 200 MSPS at the most. The ADCs used inside have the 300 MHz capability. But the lower sample rate is, what limits the bandwidth. If only FINRISI had provided the Equivalent Time Sampling mode, I believe it could achieve 200 MHz, if not the full 300 MHz (atleast) capability of the ADCs. Secondly it seems to lack a wideband preamp in the channels. And this limits the sensitivity of the scope. Overall treat it as a digital alternative to 20 MHz scope. Its not much better than that. If u expect to come across anything serious needing 100 MHz ability. Then don't touch this with even a 10 ft. Pole. U can get far better than this one with just 50 more dollars to the budget. I mean genuine 100 MHz touch screen scope with good sensitivity. This stuff has a poor performance to price ratio. Its not worth its cost.
@@RaM-xy8kg Consider Hantek TO-1112C. Its a touch tablet scope 100 MHz bandwidth. Currently at 180 dollars. Its a 250 MSPS scope with the normal sensitivity down to about 50 mV/div or less, with full bandwidth. If u can spend another 200 dollars. Then u get the 1 GSPS, Hantek TO-1202. Which is 200 MHz bandwidth. These scopes are all touch screen scopes. So no unreliable mechanical controls. I would say best price to performance ratio. If touch screen reliability is not so much required. Then go for variants of Owon 2102. Owon 2102 is a genuine 1 GSPS scope. It sells under different brand names like Labloot, Rui shi, Hanmatek etc. Some of them going down to as below as 150 dollars. Owon is really good. One is amazed at the stability of waveform and low noise. Those are two areas where it seems to beat even Hantek. However Hantek offers in some scopes the ETS (Equivalent Time Sampling) mode. If u work in the moderate to high speed. Then ETS is an indispensable asset. Sometimes it gives u the info that u don't get with a simple DSO.
Most of my work for the past few years has been below 3ns region. Where a 200 MHz scope is pretty much insufficient. However the ETS still does some good job to an extent. Its invaluable at times. The most offensive part is the unreliability of rotary encoders. Just one bad encoder and the scope becomes a struggle to work with. Ur only resort is to replace the encoder. Owon is good, as it normally needs only a few screws to get to the board. Its a very well designed scope. And its very well supported. The owon scope that I received was a bad one. It used to get warm up a bit quickly. And it seemed to work hot. It was laying on my bench unused for a long time. And its one channel got bad. It was more than a year later. I thought that the warranty must be over. So I emailed owon to purchase a spare channel board, to fix it. After verifying its malfunction through the videos I sent them over the email. They sent me a board free of charge. And I replaced it (very easy to do that). And it is working really fine. Its not warm either as it used to get with the faulty board. I later learned that its warranty extends to 3 years. Which is very impressive. However, I cannot give a decisive statement. As it needs more time to work to establish that it was the problem of a bad unit that came out of the production and quality control. Unless it sits on my bench on a warm day and remains cool after a good while of remaining operational. Only then I can say its equal to or better than Hantek.

Grounds are not directly shared - 220 ohms between them with a tester. So some separation there.

It depends where you buy it. Lately, some Chinese suppliers (Banggood, Alibaba) are shipping it without the power pack.
I need a scope for trouble shooting and dont need much, basically radio waveforms.
I would be interested in a sweep generator, but I guess this doesn't have that. A sweep would allow for audio spectral analysis.
You’re better off buying a spectrum analyzer or a scope with a really good FFT function.
Yes, very few instruments accommodate that feature.
