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

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.

For very little money, I have myself a great little tool. It functions very well and I simply love the "view" or rather the lcd screen. I used to have a large oscilliscope with a cathode ray tube. Worlds of difference. As other reviews say, yes, it's not a precision laboratory instrument, but it is accurate enough for hobbyists and casual users. It is large enough to accomodate a easy to see screen and also a compliment of knobs and switches instead of those "multi-function buttons" found on other units.

This is a really neat little oscilloscope that's well worth the money. It behaves like advertised. The internal signal generator can only create 10MHz sine and max. 2 MHz square waves. I looked at a 50MHz clock signal from a CMOS clock oscillator (KC3225A50.0000) and it nicely shows the signal. So the 100MHz bandwidth seem to be close to the truth. When using the USB power adaptor that comes with it, there is a lot of noise on low voltage signals. I am using an iPad power supply now and the noise is gone. Hard to understand why FNIRSI ships this nice oscilloscope with such a crappy power adaptor... The oscilloscope has a very intuitive user interface. Very easy to use. Creating a custom wave form in the signal generator is not straight forward and required to look up the manual. The example in the pictures is the skyline of Chicago. Created in in matlab and sent it via the audio output to the oscilloscope. From there it can be stored as a customized wave form and it can be set to any frequency (up to 1MHz). There are a couple of things that are a bit strange: 1) When connecting the USB port to a mac, the connection cannot be terminated - other than turning the oscilloscope off. (at least I didn't find anything) 2) The screenshot bitmaps all have a time stamp of Mar 22, 2020. 3) The Voltage reading is a bit on the high side (5-10%). It would be nice if the Voltage scale could be calibrated. Yet, for the price it's great and it does what it's supposed to do. I don't regret buying it! I would buy it again. Update Dec. 2024. After buying a Rigol DS1202Z-E in 2023, I realize that I hardly ever turn my FNIRSI on anymore. I have to admit, that the FNIRSI is really only for the very beginner. Also, it is clear now, that over 30MHz the FNIRSI gives very inaccurate results. The Rigol is twice the price, but it can do a huge amount of things more than the FNIRSI. Today, I would not buy the FNIRSI again.

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 .

Good product

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

It delivers.

Perfetto nella spedizione. Lo strumento non arriva a 100 Mhz, ma era un aspetto conosciuto. In rete si trovano diverse recensioni che descrivono le caratteristiche dello strumento. È perferto per un hobbista, e per chi nonnlavora in alta frequenza (dino an39 Mhz ci arriva, poi taglia troppo). Il generatore di segnale incorporato funziona bene ed è utilissimo (sempre per uso hobbistico). Per utilizzi in b.f. è ideale (es.: nel campo audio)
