FNIRSI DPOS350P Tablet Oscilloscope

FNIRSI DPOS350P highlights

Powerful Multi-function Integration

The DPOS350P integrates a 350MHz oscilloscope, 50MHz signal generator, 200K~350MHz spectrum analyzer, and 50MHz frequency response analyzer, making it a versatile solution for industrial, research, and maintenance applications.

High-Performance Waveform Capture

With a 1GSPS real-time sampling rate, 350MHz analog bandwidth (single-channel), and 50,000 wfm/s waveform refresh rate, it accurately captures and displays even low-probability anomaly signals for precise analysis.

Fine Display and Operation

Featuring a high-resolution 1024x600 IPS touchscreen, the DPOS350P offers clear waveform display with grayscale and color temperature mode switching, ensuring ease of use in various testing environments.

Rich Signal Generation and Analysis Capabilities

The built-in 50MHz signal generator supports 14 standard waveforms and custom waveform creation, while the 200K~350MHz spectrum analyzer is ideal for EMI, RF, and high-frequency signal testing.

High-Voltage Protection and Fast Charging

Equipped with QC18W fast charging (fully charged in 2 hours) and high-voltage protection up to 400V, the DPOS350P ensures long-term, stable operation. Its compact design makes it perfect for labs, production lines, and fieldwork.

Convenient Data Storage and Export

It supports up to 500 waveform data storage and 90 image storage, and has USB data export functionality for easy analysis and report generation.
