FNIRSI DPOS350P is a versatile and advanced 4-in-1 tablet oscilloscope that integrates four powerful tools in one device: a digital oscilloscope, signal generator, spectrum analyzer, and frequency response analyzer. Designed for professional use in laboratories, service departments, production, and research environments, it offers a high-performance measurement solution in a compact format.

With a 350 MHz analog bandwidth and 1 GSPS sampling rate, it enables precise signal capture and analysis. The large 7-inch IPS touchscreen with a resolution of 1024×600 provides clear visibility and intuitive control, even in bright conditions. The vertical sensitivity range of 2mV–20V (1X probe) allows for analysis of both low and high voltage signals.
The integrated function generator can output 14 standard waveform types as well as user-defined signals up to 50 MHz (sine wave), making it ideal for simulation, circuit testing, and signal injection. The spectrum analyzer function covers a frequency range from 200 kHz to 350 MHz with 3D waterfall visualization and advanced measurement functions. The built-in frequency response analyzer (FRA) enables precise frequency characterization of electronic circuits—essential for analog system engineers and filter designers.
With over-voltage protection up to 400V, QC18W fast charging (fully charged in approx. 2 hours), and internal storage for up to 500 waveforms and 90 screenshots, this device is both safe and efficient. Data export is easy via USB, and firmware can be upgraded for future improvements. The multi-language interface, auto-calibration, and intuitive controls make the DPOS350P a professional-grade measurement tool for a wide range of applications.

Lightweight and compact, the DPOS350P is a fully portable and reliable solution. It’s ideal not only for lab measurements but also for field diagnostics and equipment servicing. Its all-in-one functionality replaces multiple devices, saving space and cost—making it a perfect choice for users seeking a precise and integrated measurement system.
