![]() ![]() ![]() I own a few FNIRSI items, but not their junky scope. The firmware was updated about a year ago to fix a timebase error on the highest sweep speed and my unit arrived with the bug fix already in. Data is downloadable from the scope, but I haven’t used the feature. The unit can also be run from its USB-C port, but I wouldn’t want to count on cat III/IV safety rating when powering by USB. I also like that the power source is two 18650 cells that provide hours of use and extra cells are cheap and easy to pack in my tool bag. Between DC and 100 MHz sensitivity is flat to within +/- 1 dB. At 200 MHz, the input sensitivity is down about 3 dB. The scope section is quite good and will tigger stably on inputs over 200 MHz in single channel mode. I was able to find the HDS-2102S for about $220 US. The signal generator is probably a little less versatile than I’d like, but OK for field work. It is a very good instrument which includes a two-channel 100 MHz scope, a Cat III/IV true RMS meter electrically isolated, a 25 MHz Arb signal generator, and a 100 MHz probe and meter leads, etc. I have an Owon HDS-2012S scope meter in my tool bag.

Spend a little more money on the USB analyzer module and get more channels and/or speed.ġ. Then run the module with the free open-source cross-platform Sigrock back-end plus any of various front-ends like PulseView and you have both a logic analyzer and serial bus analyzer that understands most common protocols. So spend less than $20 online (even less on AliExpress) for an 8 ch. If you’re reading Hackaday I’ll assume you have a PC or laptop. ![]() ![]() Posted in Reviews Tagged FNIRSI, oscilloscope, rigol Post said: “Pity it lacks serial decoding – a great feature to have.” We know that not all FNIRSI scopes live up to their supposed specifications. We actually looked at the original review that this video refers to. If you have either of these scopes - or both - what do you think of the review? Leave us a note in the comments. You like what you like, and it doesn’t always have to make sense. Besides that, your choice of a tool as integral to your day as a scope or a soldering iron is pretty personal. On the other hand, everyone’s use cases are different. But in real life, you’ll never notice the difference. One PC is good because it scores 1% higher on a benchmark than another. Honestly, we are as guilty as the next person of getting obsessed with specifications. If you are in the market for a scope in this price range, it is worth the time to watch. He uses both scopes in some real-world measurements. The 46-minute-long video does more than just a casual look. To be clear, he didn’t think it was a perfect scope, but he did find it very usable for his purpose. His results were different from what we usually hear. had heard from another YouTuber that it was “a piece of junk.” However, he wanted to look at it compared to another inexpensive scope, the Rigol DS1052E. We’ve heard of the FNIRSI 1014D scope, but we’ve had the impression that it might not be a great scope, although it is economical. ![]()
