The compact 2‑in‑1 oscilloscope and signal generator FNIRSI DSO153 offers a palm‑sized tool for analyzing and generating signals anywhere. It features a 1 MHz bandwidth, 5 Ms/s sampling, measures 12 types of values, and supports auto setup. With a 1,000 mAh battery, USB‑C, and intuitive controls, it’s ideal for DIY, service, and education.
FNIRSI DSO153 is a lightweight and smart helper for the workshop and field. It combines a precise oscilloscope with a practical signal generator, so you can easily verify waveforms, find interference, and test circuits. It offers pause, zoom, and waveform panning, automatic measurements, and overload protection.
For convenient use, it includes a 90° stand, mode switch, fast USB‑C charging, and support for 8 languages. Auto power‑off saves energy, so the device lasts longer in operation even outside the lab.
