FNIRSI 1014D Oscilloscope 2 in 1 Digital Oscilloscope DDS Signal Generator, 100X High Voltage Probe, 2 Channels 100Mhz Bandwidth 1GSa/s Sampling Rate Built-in 1GB Storage Space

First, if you are expecting a sub $200 scope to function with the same features and accuracy as a multi hundred or thousand + pro level scope, keep moving. You're just wasting everyone's time. Now. If you are an electronics DIYer, or dabble in repairing old PCs, consoles, stereo equipment, or other small electronics, and it's just a hobby or side gig, and you are ready to step your game up from the multi meter to an actual oscilloscope, then keep reading. It's small footprint fits on any bench and tucks away neatly for storage between uses. It comes with all of the basic probes and clamps you need to get started. It is capable of USB power, so it is capable of being isolated from MAINS power (if you know, you know) Tests continuity of circuits, signal from chips and circuits, functions as a signal generator, tests analog and digital circuits, can export results, and has the resolution to be functional and capable at the hobby/diyer level. HIGHLY recommend if this is your first foray into using an Oscilloscope for more advanced testing and diagnostics, that you spend some time on Youtube before you dive in. But if you are ready, this is a low cost, high function, reliable solution for the first timer, diyer, and active hobbyist.

Shipping was prompt and the package arrived as scheduled. The packaging was impeccable. This little oscilloscope could have survived about any incident I can imagine it having to possibly go through during shipping. I was very pleased with how compact and lightweight it is. It's been about thirty years since I've used an o'scope and from memory they used to be horrendously bulky and heavy beasts. For my purposes, in my little amplifier and guitar repair operation, this gem is exactly the right dimensions and weight. My initial read through of the manual was only a little bit confusing but after sitting down and going through the operation section step by step to familiarize myself with it's buttons and knobs and their functions I found it quite easy to operate and with numerous features (such as an included 100X probe for high voltage work) that are admirable. Calibrating the 1X/10X probes was a breeze with the little calibration tool (flat top screwdriver) supplied. And it sits atop the shelf above my workbench in perfect viewing position right next to my multimeter and soldering station making it highly accessable which is a huge plus for me. So far the only negative attribute is that the output potential of the signal generator isn't adjustable from it's rated 2V pp. For use in guitar amplifiers I need a much lesser input in mV. So I will probably have to add a stand alone signal generator to my list of equipment. But I was aware of this feature when I bought it so I won't detract from my rating for it. For other purposes not requiring a smaller input potential this built in signal generator will work well. I haven't had the opportunity to try it out in actual signal tracing yet as I'm waiting for load ballast resistors to arrive but I have no compulsions to think it will do anything but serve me well at this point. So up to this point I am quite pleased with this item all around excepting where noted above. The price is definitely a value for everything this little unit can do.

The good: (1) Wow, this little oscilloscope offers quite a lot of bang for the buck. Back in the day, a scope that would do half this much weighed as much as a large, fully stuffed suitcase. I ran this little thing through its paces in my laptop, sitting on the sofa. Incredible! (2) The scope seems pretty accurate. (3) Love the built-in signal generator. I wish it had amplitude control, but it's wonderful nevertheless. (4) The controls are easy to use - intuitive, once you get the hang of the scope. (5) Other reviewers complained about noise from the cheapo power supply. I could detect no such noise, even at full gain (50 mV/div). They must have responded to reviewers' concerns and started using a smoother power supply. (6) The "Auto" button is amazing - a real time-saver. Just press it, and the scope will quickly give you a viewable amplitude and sweep rate to view the waveform. Then tweak the settings from there to your needs. This is not to be confused with auto triggering, which is another function. The bad: (1) The instructions are microscopic. The text is readable with effort. The numbers on the diagram are not, at least by the human species. Fortunately the manual can be viewed and printed in readable format from the fixlib website. (Print to PDF for an electronic copy.) The text is poorly (but not horribly) translated Chinese. Strangely, the specifications for the scope aren't printed in the manual. (2) The FFT display is useless, as there is no way to read off the frequency or amplitude values. The horizontal cursor displays not only time (for the primary display), but also frequency (for the FFT). However, the frequency values are complete nonsense, undoubtedly because of a firmware error. And the vertical cursor does not display the FFT amplitude. The FFT is therefore only useful for determining if there is distortion in a sinusoidal signal, but there is no way to get any sort of value of % THD. This is in contrast to a Hantek oscilloscope module (with interfacing through a computer via USB) that I bought maybe 10 or 12 years ago, which did an incredibly competent job of displaying FFT information. The FFT display seems to have been an afterthought, perhaps to display the internal function used to measure the frequency of the waveform (which is nicely displayed). (3) Watch your input voltage! The label next to the BNC connectors says 400V max. However, that seems to be only when using a 10x probe. If you read the instructions, the true input maximum is 40V at 1x, 400V at 10x, and apparently 4kV at 100X, EXCEPT that the supplied 100X probe indicates 2 kV max. Truthfully I don't know whether voltages above 40V and below 400V (input directly at 1x, straight into the BNC) would blow anything up. (4) I've seen testing on this scope that demonstrates it has difficulty displaying and measuring a 100 MHz signal. If you need to measure frequencies this high (I don't), then you should do your homework to determine whether the manufacturer has resolved this issue. (5) The price dropped literally the day after I bought it. It seems pricing of this unit is very Keynesian: When demand goes up, price goes up too. That can leave you feeling a bit cheated. (6) If you are used excellent scopes such as Tektronix makes, this one will seem pretty flimsy. If you plan to use it daily, you might consider a more expensive scope. If you only need it for occasional use, it should be fine. All in all, it seems to be a very nice little basic scope - adequate for my needs of occasional circuit prototyping. Great value, to be sure.

This is a really great oscilloscope at a low-low price. The 10:1 probes are also quite good. And it has a built-in signal generator. It wasn't long ago, you would pay $1000 or more to get a 'scope with all these features and quality.

The product was definitely sealed brand new in the box with shrink wrap on the box… And yet I hooked everything up and powered it on for the very first time excited to use it, and the screen seems to be busted underneath… you can’t really tell when the device is not on… The screen is busted from behind… but, and it’s current state it is completely useless. UPDATE: The replacement unit came in… I recorded a video of me unboxing the new one just in case it didn’t work. Amazon will not let me upload it because the video was too long. This was definitely a brand new unit. The product itself is shrink wrapped and then packaged with foam on all sides of the product. These are actually packaged extremely well. The box itself was shrink wrapped as well… And yet, as you will see in my video, I got a little bit further with this one… Instead of hitting the power button, and getting a broken screen, I noticed that the power button was partially jammed in… I was able to unjam it by pressing it. The logo screen showed up and I was feeling very optimistic… And then a little line shot across the screen, and everything went black. The screen didn’t come back on again… I tried turning it on again, after pressing the power button a few times, I got the logo screen again… And then I realized what was happening, the device is shutting itself back off immediately … it does not work. That is two brand new items completely defective out of the box. This is a TRASH company. There is no way that they quality check their products if they are sending them out like this. What are the chances of getting two completely broken items back to back if they are actually quality checking the build process? At this point, I am behind schedule on something that I was supposed to work on for somebody and I’m absolutely livid… I realize you get what you pay for… But I paid almost $200. When I bought this, the price wasn’t discounted down to 170… and for $200 I don’t expect the most amazing oscilloscope on the market… But I do expect one that actually works and functions … This company has wasted so much of my time sending me out their crap… They don’t even make sure that their products work before they package and send it… I will never purchase another object from this company ever ever again…. I cannot believe that they do not have more respect for their own brand name to at least make sure that an item is in working order before sending it out and letting people get a negative impression of their merchandise…. I now have to drive all the way into town to the Whole Foods store to drop these two giant plastic paper weights back off so that I don’t get charged for this useless garbage… and until I do that, I cannot order a working one… Because I don’t get the refund until I drop the merchandise off. So I highly suggest nobody order this product because you are taking a major gamble. It is Crystal clear that they do not check these at all before they package them up and sell them. There are a couple others from other companies around the same price range… FNIRSI wants you to buy the other brands… They want you to leave negative reviews on their items, they want you to drive them out of business… And that’s why they don’t even bother to make sure their products work before selling them… if you want to do business with a company like that, you might as well, at least save yourself some time and skip the part where you buy their broken merchandise and just go straight to the other brand’s products… Two defective units in a row is absolutely inexcusable in my book.

Has been my standard at my desk for an year now. Does things reliably well for good complexity hobby level work. No CH1-Ch2 math. Has XY plotting option and has a rudimentary spectrum analyzer too. Signal gen can only do ac signals. But that is easily dc coupled and usable. Great value for money. Works very well.

One year later and this scope still works. Take care of your tools and they take care of you. I have successfully repaired several game consoles using this scope. Yes its not a high end scope, but any tool in capable hands can help you successfully diagnose and repair what your working on. I spent a couple of months watching videos and comparing specs before I bought this scope. Great value for the price. Accurate fast information when looking for signals that are intermittent when wiggling component's. Fits in my small work space easily and is durable enough to take a couple of falls. Great affordable scope to get your feet with, that will actually help you fix electronics.

Good little scope, haven't used all the features...yet. Takes a little getting use to it. Use of auto setup seem to work, but is not ideal for triggering, which takes some patients. The readouts measurements are good to have. The waveform generator is handy, but can be complex if you let it. It does have a USB port to download or control stuff... I have not used that part yet. The probes appear to be pretty good, The 10 X are what I use for speed and circuit loading. The scope is ground isolated which makes some jobs easier and safer.

I recently purchased this scope from Amazon and had a fantastic experience with both the product and the vendor's customer support. The scope itself is impressive. It's not only easy to use but also delivers quick and accurate results. As a beginner, it serves as a great entry-level scope, making it perfect for those new to the world of scopes and measurements. What truly sets this purchase apart is the outstanding customer support provided by the vendor. When I encountered an issue with one of the probes, their response was swift and efficient. They promptly sent a replacement probe, demonstrating their commitment to customer satisfaction. Moreover, the scope's signal generating functions have proven to be incredibly useful for my needs, adding extra value to the product. I highly recommend this scope for anyone in need of a reliable and user-friendly tool, backed by excellent customer support. It's a purchase I'm genuinely satisfied with. I hope this review helps you convey your experience accurately and helps other potential buyers make an informed decision.

Het toestel is nog veilig in gepakt in de originele verpakking tot dat m,n werkplaats is aangepast . Nadien wordt het toestel uitgetest en gebruikt voor wat het toestel is ontworpen .

User interface is intuitive and display is clear. Tested up to 30mhz and all seemed reasonably accurate.

Beautiful product. Better than I could have imagined. More functions than I had expected. Light and well made. Couldn’t have asked for more. Price amazing

It delivers.
