Good product and orginal

Nice product 👌

水晶振動子の動作確認用に使いましたが正確に発信周波数をとらえています。

muy útil

Osciloscópio portátil apresenta uma construção bem robusta, simples de usar. Qualquer coisa, pode usar o manual ou pesquisar no youtube o canal do fabricante que acha videos curtos explicando o uso. Além disso, vem com uma bolsa para guardar o dispositivo. Bom custo benefício pelas funcionalidades que oferece. Mas a tela não é tão grande, mas para pequenas aplicações já é suficiente.

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.

It's a great product for all technicians.I had used this product before in another country its very nice and easy to use.
