- Field technicians needing a portable multi-function tool
- Makers debugging microcontroller and sensor projects
Considerations
- The 50 MHz bandwidth limitation in dual-channel mode may be restrictive for higher-frequency applications
- Memory depth tops out at 1M points—adequate for most portable use, but less than benchtop instruments
- The 3 Vpp maximum output from the signal generator limits its use for driving certain loads
Summary
The FNIRSI 2D15P offers a practical combination of oscilloscope, multimeter, and signal generator functions in a battery-powered, touchscreen device. Its 100 MHz bandwidth, 500 MSa/s sampling, and True RMS multimeter make it a capable tool for general electronics work, troubleshooting, and education—provided its limitations fit your requirements.

I recently purchased the FNIRSI 2D15P and I am extremely pleased with its performance. The unit feels solid the interface is easy to use and the display is bright and clear. For quick measurements troubleshooting and everyday electronics work this oscilloscope performs far better than I expected at this price.
Judy S. (verified owner) –
I am so impressed with all my new tools. I have purchased one tool after another from FNIRSI. I am impressed every time. I work in the Automotive field and I am sure that co-workers think I work for the company.
Dale C. (verified owner) –
This scope has big performance in a small package. Many features of an expensive scope. Love it.
Theodore R. (verified owner) –
FNIRSI continues to produce excellent quality tech tools at an affordable price. Multifunctional devices in a single form factor is the way to go. Please work on the user manuals to ensure a good flow of instructional information and provide supporting videos.

Overall this instrument is a good value. However I could not find or figure out how to use the FFT feature.
Csongor V. (verified owner) –
I never owned a scope before and only used one back in university. I am not an electronics engineer but there are cases when a simple multimeter is not enough and I need to see a signal. I think this device will do just fine for me for many years. I like the relatively small size and battery operation.

Bill S. (verified owner) –
Of all the scopes I have owned throughout my years they all had an option to toggle the scopes inputs to ground. This scope does not offer that option. I have also noticed when pressing the keys Cursor/Display/Measure/Math/Trigger/Menu the same top section is displayed.
Andrei P.L. (verified owner) –
I have ordered three hs-02 soldering irons and a component tester and the new 3 in 1 oscilloscope. They work flawlessly and I would really love to see more options in the soldering iron regarding power selection and more features like signal decoding on the oscilloscope.

This device is easy to use valuable to the bench for diagnostic and at a price that was shockingly low!
Vitor P. (verified owner) –
After 2 days of usage fan started to make loud noises and the multimeter mA socket does not work – need to put the probe on the A socket to get readings.
Harald B. (verified owner) –
Missing the possibility to connect power cable instead of only power from the built in battery.
Nikolai D. (verified owner) –
Working very good. Great tool for this price!

Paul D. (verified owner) –
Great little piece of gear arrived quickly and well packaged.
Paul W. (verified owner) –
Great scope fits in my backpack. I only wish one thing that the signal generator would put out 4 volts P-P so you can use it to calibrate pro audio equipment. (+4dBu = 3.47V p-p)
Dennis C. (verified owner) –
I cannot praise this item enough it is just perfect in all ways its price its versatility and compact to pack a punch great piece of kit.
