Working with electronics on the bench (and sometimes in the field), I didn’t expect something this compact to replace multiple tools—but the FNIRSI 2C53T genuinely surprised me. Three Tools, One Device—And It’s Not a Gimmick Instead of juggling a scope, multimeter, and signal generator, I’ve got all three in one unit. It’s not just a “nice to have”—it actually saves space and speeds up troubleshooting. The device combines these functions into a single compact package, essentially replacing multiple instruments in one go. Performance That Punches Above Its Size For a handheld unit, the 50MHz bandwidth and 250MS/s sampling rate are more than enough for most embedded work, power electronics debugging, and general signal analysis. It captures signals cleanly, and the display is bright and easy to read. Great for Real-World Debugging I’ve used it on microcontroller projects, power supplies, and even quick field diagnostics. The built-in battery lasts several hours, which makes it practical when I’m not near my main bench setup. Feature-Rich Without Being Overwhelming Things like XY mode, persistence, and waveform math are included, which you don’t usually expect at this price point. The interface is straightforward enough that I didn’t need to dig through a manual to get started. A Legit Tool for Hobbyists and Pros This isn’t replacing a high-end bench oscilloscope—but it’s not trying to. For portability, versatility, and value, it’s one of those tools I keep reaching for more than I expected.

At this point I've lost track of how much FNIRSI equipment I own. I have at least two oscilloscopes and two of these scopemeters, plus a Geiger counter/RF/magnetic field meter, LCR meter, volatile gas detector, portable soldering iron, and I'm not even sure what else :) This is another nice, inexpensive product with loads of features and excellent build quality. I bought it because I need to set up a mobile lab and while I don't often need a scope on the road, I OCCASIONALLY need one, so buying a scopemeter was the right path. Like all of FNIRSI's multifunction devices, it's packed with useful features. All the probes you'd need are included. Multimeter and oscilloscope are full-function and the display is bright and legible for both. If you're used to FNIRSI's touchscreen scopes, well, this isn't like that - it is more like a traditional buttons-and-knobs scope, but not quite. The learning curve isn't too bad and you'll be familiar with it in a half-hour of tinkering. UI defaults to Chinese, or at least it did for me - if you don't read Chinese, you'll have to navigate blind to the settings screen, where - luckily - Chinese/English selection is the first option. It's pretty obvious how to get there. Chinese is also the first language in the instruction manual but the English version is right after it and is easy to understand. Another great product!

This works pretty close to its claims and is undoubtedly a good value. The bandwidth claim is more honest than many others out there, that's for sure. And I have tested many. My test equipment only goes up to 40 MHz but handled up to a 40 MHz sine wave without any amplitude degradation. That's the good news. The bad news is that the amplitude INCREASED with the frequency both as the displayed waveform and the calculated value displayed. A 10 Vp-p 100 kHz sine wave showed as 10.25 Vp-p. This kept increasing with frequency until it showed 11.9 Vp-p for a 10 Vp-p sine wave. But there was one highly annoying behavior. When you press AUTO, it automatically sets volts/division and the timebase but sometimes gets confused. Such as if I suddenly gave it a 30 MHz square wave. It continues to display "Awaiting Auto Measurement." I pressed every button to try and get out of it. Even the POWER button would not work. I disconnected the signal, and it continued to be "locked up." After another minute, it magically cleared itself. Total time was over two minutes. I saw this several times. An annoyance like this is really enough to give zero stars and reject the item outright. But its price is so low and so much of it works reasonably well that it is still worth considering. But the manufacturer REALLY should not have a design can lock up the system leaving you helpless. If this happens to you much, you will probably give up on "AUTO" and make those settings manually. I also focused on AC voltage measurement. The manufacturer does not state the AC frequency response in advertising, and not even in their manual. (It is an important spec and should at least be in the manual.). A query to them produced an answer that is about 450 Hz. So, it is minimal, but that is common for most inexpensive meters. In testing, it was excellent for a sine wave up to 1.5 kHz. The manufacturer also said it was not "True RMS." This usually means a square wave reading will be 11% too high. But a 400 Hz 10 Vp-p square wave read 9.732 Vac (10.000 would be perfect). The device may be trying to figure out something about the AC wave shape after all.

As a mechatronics student im constantly jumping between mechanical systems, electronics and firmware debugging. Carrying separate bench tools to the lab or working on projects at home was always a hassle until I picked this up. The 3 in 1 functionality is where this device truly shines for my coursework. The upgraded architecture makes the interface snappy and the waveform capture reliable. I really like how theres a Type-C charging and the battery too which easily lasts through my long lab sessions. Being able to save and export waveform screenshots via USB C is also a huge plus for documenting results in my lab reports. While it wont replace a highend 1kbench scope for extremely highfrequency work it is more than capable for 90% of what I encounter in robotics and embedded systems. For the price you simply cannot beat the value and portability. It’s easily the most useful tool in my engineering kit!

This is a gem! Watch the Kerry Wong video closely that’s on YouTube… a few times! I like the layout and buttons. It takes some practice, but the scope is great as well as the characterization feature. It’s handy as I don’t have to drag out by big scope to remote locations. I liked it so much I got the 2c53p,,, it was awful and I’m returning it!

Wow, these guys make a lot of instruments! So I chose the FNIRSI. I started exploring the user interface and found a maze. My closet gear is Tek and Fluke. How complicated can you make an oscilloscope? Well, when you look at how many different models FNRSI makes, your answer is there. They seem to create different models with different menu mazes. The company's own video prides itself on their vast tree of functions. But after trying to navigate to basics I got lost and lost interest. In spite of all the promise, the cool look, the huge variety of instruments that FRNSI makes (and the nice carrying case it came with ;-) ). It was tediously slow to use. You want a scope or a Rubic’s cube? And then the bugs started, many leading to the FNIRSI 2C53T bricking up, with NO way to recover, other than waiting for the battery to run down. Updating the firmware changed nothing. No fun. One star, returning. I had also ordered a similarly featured unit from a smaller company, ZOYI, that turned out to have a clear menu and button structure with direct access to functions, like it was designed by a multi-meter company. I prefer that. It goes to show that an impressive range of models and features s no proof of a company's footing.

Okay... this things is pretty nice. Very pleased. Very decent build quality. Case and accessories are nicely configured. Quick and easy tester for numerous electronic component values. Auto mode is excellent. Oscilloscope and Signal Generator look interesting... probably useful but I will likely just use my desktop units.

Good meter for standard troubleshooting. Not recommended for precision calibration use. All functions work as needed. O-scope is limited in adjustment but it does work. I was able to use it to see the 20-70ms pulse width signals from a breaktor module on a EV battery disconnect. Everything else I have used it for has been basic and it works as needed. The battery holds up well so far. Did not like to use this meter at 1st but has become my go to meter as I get more familiar with its abilities. I would recommend this for advanced or advancing electrical users. Not ideal for beginners as you need an advanced understanding of electricity to understand the settings needed to get desired results. The unit has a nice auto feature to help with this but I find the auto readings are not always what I am after. The manual settings can get you dialed in. If you need advanced readings for troubleshooting then this meter will most likely get you what you need. If you don’t need the advanced readings then get a simple meter.
