FNIRSI® 2D15P 3-in-1 Tischgerät 2-Kanal 100MHz Phosphor-Oszilloskop Multimeter

Great scope for remote work, always carry it in my bag and easy to set up and use!

Just getting started but this seems like a perfect balance of capabilities, price and ui. Still looking for some good training videos on following IC traces.

El paquete fue recibido en el tiermpo estipulado. se cumplio con todo lo ofrecido por FNIRSI. El Osciloscopio 3 en 1 llego en perfecto estado.

Uma sugestão para atualização , a escala de multímetro em diodo poderia ter bipe quando em curto e até mesmo ao medir dar bipe indicando que foi detectadoe se em curto bipe continuo isso seria perfeito , evita fica olhando fixado para tela , do mais o produto é ótimo , mas se adicionar esta função iria ficar super ótimo

Great little scope to have on the fly and works with automobiles as well.

Ho provato tutte le funzioni di questo dispositivo e funziona perfettamente. L’oscilloscopio mostra chiaramente tutti i segnali

Good value for $150, combining an oscilloscope, a function generator and a digital multimeter all in one small package. I'm a hobbyist building amplifiers and speakers, so this device allows me to measure ripple noise in my linear power supplies and power outputs in my amplifiers. One star off due to the included DMM test probes that are so mediocre. See my pics on the set up to measure amplifier output.

Hello,
I’ve been using the FNIRSI 2D15P for a few days now and wanted to share some feedback based on hands-on measurements.
Overall, I’m very satisfied with the device. For a portable oscilloscope/multimeter in this price range, it offers a surprisingly capable and usable tool. The interface is intuitive, startup is fast, and the screen is clear enough for real work, not just casual checks.
I performed a simple frequency response characterization using a TinySA Ultra as a signal source. The results are consistent with the advertised specifications: the waveform remains clean and stable up to several tens of MHz, and the amplitude response stays within a few dB up to around 100 MHz. For a handheld device, this is quite impressive and perfectly usable in practice.
A few points I particularly appreciated:
* Stable triggering in most practical situations
* Good sampling performance (500 MSa/s in single channel mode)
* USB sharing function (once understood) is very useful to extract screenshots
* Solid build and overall usability
There are also a few areas where improvements would be welcome:
* USB behavior is not very intuitive at first (USB sharing vs USB storage could be clarified in the documentation)
* Some measurements (like rise time on fast edges) require careful interpretation, which might benefit from clearer documentation or examples
* It would be great to have more explicit technical documentation on bandwidth and measurement methodology
In summary, this is a very good instrument for its class. With a bit more documentation clarity and minor usability improvements, it could be even better.

ma nejake chybicky ale funguje na moje servisne potreby celkom dobre

It is a very easy-to-use and versatile device.
The oscilloscope works great, the multimeter function is also excellent, and the signal generator is brilliant.
Everything went smoothly with the order, payment, and delivery as well, and the device fully matches the description.
I can recommend it.

Muy rápido en llegar el pedido, por ahora estoy contentísimo con él y su funcionalidad.

This is my first FNIRSI product I have purchased. The 2D15P arrived in a well-packaged box with everything I needed for a portable multimeter/oscilloscope unit. The product is very well-built, and the user interface is intuitive. The best quality for the price paid for the equipment. Is it as good as my $30k Keysight/Agilent oscilloscope? No, but it gives me a quick, reliable way to measure my circuits in the field or on a bench, without expensive equipment. I love that it's battery-powered, so the AC noise coupling from the power line is less of a concern, and it's very portable. I don't yet know the long-term reliability, as it's only been a few months, but I will definitely be buying more FNIRSI equipment in the future.

I found a nice protective case meant for an external hard drive that fits the unit and accessories perfectly. Now I can take it anywhere.

For the price, it doesn’t get much better than this. The unit even arrived a day early. Loads of functions on this - couldn’t be happier for my first scope.

This device is easy to use, valuable to the bench for diagnostic and at a price that was shockingly low!

El envío me sorprendió por lo rápido y lo bien empacado que estaba.
Sobre el 2D15P pues es un equipo que cumple con lo básico pero el ancho de banda real del osciloscopio es de 40 MHz en el mejor de los casos, los datos de medición deberían ser un poco más grandes, el auto set se pierde o le cuesta ajustar bien.
La capacidad de la bateria es muy limitada y el no agregar un cargador por lo menos a mí parecer es un fallo.
La sondas del osciloscopio se ven a leguas que son de pésima calidad.
Pero repito es un equipo que cumple si no tienes altas necesidades o exigencias.

コンパクトでバッテリー駆動できるので、まず波形を確認しようというモチベになる。また、基本のオシロ機能・テスターの機能（コンデンサの容量も確認できる）・Eye patternを見る機能など十分な性能。エクスポート（データの出力機能）が画面のキャプチャをbmp出力だけなのがちょっと残念。データロガーが出来たら、星6つあげたい

1) Of all the scopes I've owned throughout my years, they all had an option to toggle the scopes inputs to ground. This scope doesn't offer that option.
2) I've noticed when I press the keys/buttons Cursor/Display/Measure/Math/Trigger/Menu, the same top section is displayed. I realize when pressing any one of those listed above provide the options on it. That's five hard buttons/keys, where they could have just one key, then the operator chooses which function they want. Kind of like what the 'MENU' button is labeled for.
3) FNIRSI could have had those BNC connectors a little further out, making it easier to connect/disconnect the scope probes BNCs
4) Don't understand why they have the DDS lighted up all the time. I don’t think it was absolutely necessary. I guess it's just for the technician to see where it's at.

Schnell geliefert in einer guten Verpackung. Alles was man braucht wurde als Zubehör mitgeliefert. Der Touchscreen funktioniert gut und viele Einstellungen ( wenn man sich damit etwas auskennt) sind selbsterklärend, aber eine deutsche Beschreibung wäre trotzdem nützlich. Display ist sehr gut ablesbar und die Messwerte stimmen ganz gut.
Habe noch 2 Geräte von dieser Firma, die alle sehr gut funktionieren. Das Preis/Leistungsverhältniss ist sehr gut.

Great product, fast (for our max 100 mhz band!) good precision e responsivity. LCD view is amazing! TOP for maker and pro!

Overall this instrument is a good value. However, I couldn’t find or figure out how to use FFT feature.
