Oscilloscope, Spectral Analyzer, Signal Generator FNIRSI DPOS350P

Product detailed description

The FNIRSI DPOS350P is a powerful and versatile 4-in-1 instrument that combines a digital phosphor oscilloscope with a bandwidth of 350 MHz, a full-featured signal generator up to 50 MHz, a spectrum analyzer with a range of 200 kHz to 350 MHz, and a frequency response analyzer. It is designed for professional use in laboratories, R&D centers, manufacturing facilities, and technical maintenance—simply anywhere where precise real-time analysis of electrical signals is required. Thanks to a sampling rate of 1 GSa/s, an ultra-fast refresh rate of 50,000 waveforms per second, and intelligent digital triggering, it can capture even very short-duration anomalies and complex signal phenomena.

Precise display and intuitive controls:
The device is equipped with a 7-inch IPS touchscreen display with a resolution of 1024 × 600 px, which offers both a standard color display and a color temperature mode, with intuitive controls optimized for precise measurements. In oscilloscope mode, various types of measurements can be performed—time, voltage, frequency, level, period, and more. In addition, it supports FFT, ZOOM, and XY display modes, as well as automatic tuning and one-button zeroing. The oscilloscope operates with two channels, offers switchable attenuation (1X / 10X / 100X), a memory depth of 60Kpts, and a time base range from 5 ns to 50 s.

Advanced Signal Generation and Analysis
The integrated signal generator supports 14 standard waveforms as well as custom waveforms (up to 500 groups), with a sine wave frequency range of up to 50 MHz. Settings include fine tuning of frequency (1 Hz), amplitude (0–5 VPP), offset (±2.5 V), and duty cycle with a resolution of up to 0.1%. The frequency analyzer covers the range from 100 Hz to 50 MHz with the ability to measure gain, phase, and frequency, including support for system calibration.

High-Performance Spectral Analyzer
The spectrum analyzer uses an FFT with a length of up to 32K and allows for the display of a classic spectrum, a waterfall plot, and 3D visualizations. It operates in the range from 200 kHz to 350 MHz and provides measurements up to +260 dBmV. It offers both frequency and amplitude measurements using a cursor and displays the signal’s harmonic components. It also features an automatic tuning function and supports system calibration.

Storage, Battery Life, and Connectivity
The DPOS350P supports storage of up to 500 waveforms and 90 screenshots, data export via USB, and easy browsing of stored data directly on the device.Power is provided by an 8000 mAh lithium-ion battery with support for QC18W fast charging (12 V / 1.5 A), which ensures approximately 3 hours of operation. The device’s total power consumption is 10 W, and cooling is provided by active air cooling. The device supports firmware updates via .iso images, automatic shutdown, a choice of multiple languages (including English, Chinese, and Russian), and is equipped with surge protection up to 400 V.

Compact, but without compromise
With its compact dimensions of 190 × 128 × 37 mm, high performance, and versatile features, the FNIRSI DPOS350P is the ideal tool for anyone who needs to reliably measure, analyze, and visualize a wide range of electrical signals—from development and diagnostics to final quality control.
