Pros and Cons

Strengths & Weaknesses:

What I Like

— 3-in-1 functionality (multimeter, oscilloscope, signal generator)
— 2-channel 100MHz bandwidth for detailed signal analysis
— High 20,000 count resolution for accurate measurements
— Auto-range feature for user-friendly operation
— Phosphor oscilloscope display for smooth waveform visualization
— Compact and portable design, ideal for various environments
— Fast charging (12V PD/QC) for quick power-ups
— Good packaging and fast delivery (mentioned by users)

Points to Consider

— Multimeter probes included are of poor quality and may need replacement
— Cooling fan is constantly active, which can be noisy or distracting
— Touchscreen functionality can be inconsistent or less precise on a small screen
— Some functions may seem incomplete or not fully intuitive for all tasks
— Signal jitter observed during vertical adjustment of oscilloscope
— Horizontal trigger setting tied to time scale, not screen position, which can be inconvenient
— Battery life might be limited due to screen size and constant fan operation

Authentic Feedback Analysis:

⭐ 5.0/5 | AliExpress Shopper: Adquirí este producto para actualizar y reemplazar el modelo 2C53P. Llegó un poco tarde pero valió la pena, el producto llegó en buen estado, con todos los accesorios incluidos y con la última versión del software. Algo nuevo es su carga rápida, admite 12V con protocolo Power Delivery y Quick Charge lo cual se puede usar cualquier cargador de celular para cargarlo. De primeras impresiones funciona bien y fluida la opción del osciloscopio, aunque lo único incómodo es el ventilador de disipacion, el cual siempre está activo con el producto en funcionamiento. Veré que tal va con el uso diario para dar una reseña de uso.
⭐ 5.0/5 | w***d: heel fijn meetinstrument om mee te werken . snelle levering goed product werkt perfect.een aanrader waar je geen spijt van krijgt.
⭐ 5.0/5 | W***h: Good packaging. The device is simply magnificent. Excellent design, materials, interface, and functionality. I like everything this company produces. Thanks to the manufacturer and seller. Good luck!
⭐ 4.0/5 | AliExpress Shopper: Приехал довольно быстро, упакован хорошо. Осциллограф интересный, довольно удобный, на столе стоит твёрдо, с хорошим по размеру, как для переносного устройства, экраном. Версия прошивки на сегодняшний день последняя, но в работе прибор всё ещё сырой. Тачскрин работает не очень уверенно: у возрастных пользователей могут возникнуть проблемы. Некоторые опции неочевидны, но разобраться можно. Что бросилось в глаза при первом знакомстве — дёрганье сигнала при вертикальной регулировке и привязка горизонтальной настройки триггера к временной шкале, а не к положению на экране. Щупы мультиметра из коробки только в мусор. Впрочем, мультиметр в этом приборе, на мой взгляд, не главное.. Пригодиться может, но отдельный прибор не заменит. Вопрос автономности пока открыт. Хотя, учитывая размер экрана и постоянно работающий вентилятор охлаждения, на долгую автономную работу не надеюсь. Пока впечатления на слабую четвёрку по пятибальной шкале. Буду изучать подробнее и следить за обновлениями прошивки.
⭐ 5.0/5 | AliExpress Shopper: schnelle Lieferung, sichere Verpackung, sehr gute Qualität, sehr empfehlenswert
⭐ 5.0/5 | F***z: Muy bueno, hasta ahora las pruebas que he hecho han sido excelentes
⭐ 4.0/5 | a***r: OK for a $130 Oscilloscope. The touch screen is not really useful on such a small screen. Some functions seem to be not complete or relevant to the task(s) being performed. I’ve owned other FNIRSI products that had similar experiences. For the price it has value in functionality but don’t think you are getting a the functionality of a $500 scope here
⭐ 5.0/5 | L***o: Thanks.
⭐ 5.0/5 | F***r: 👍🙏
⭐ 5.0/5 | R***o: It arrived in good condition, I tested it up to 60 Mhz with the 2 channels simultaneously and captured the waves well (3rd photo) exceeding its specifications without losing amplitude although some vibration was noticeable, the curious thing is that when only one channel was on the signal was amplified excessively (4th image). The only thing I didn’t like are the multimeter probes (5th), the ones that came with the 2C53T were better. Overall I am quite satisfied with the oscilloscope.
⭐ 5.0/5 | J***l: jak na moje potrzeby sprawdza się idealnie.. polecam…
⭐ 5.0/5 | I***o: very goood
