FNIRSI® DPOS350P 4-IN-1 350MHz 1GSPS Touch Screen Tablet Oscilloscope Signal Generator Spectrum Analyzer Frequency Response Analyzer

The FNIRSI® DPOS350P is a compact, touch-screen tablet instrument that integrates four essential test functions into a single portable unit: a 350MHz oscilloscope, a 50MHz signal generator, a 200K–350MHz spectrum analyzer, and a 50MHz frequency response analyzer. It is designed to address a wide range of signal testing needs in electronics development, troubleshooting, and field verification. Multi-function integration: Combines oscilloscope, signal generator, spectrum analyzer, and frequency response analyzer in one device to reduce the need for multiple instruments. High-performance waveform capture: 1GSPS real-time sampling rate, 350MHz analog bandwidth (single-channel mode), and a 50,000 wfm/s waveform refresh rate enable accurate capture and display of transient or low-probability anomaly signals. Clear touchscreen display: 7-inch 1024×600 high-resolution IPS touchscreen with support for grayscale and color temperature modes, providing clear waveform presentation and intuitive operation in different lighting conditions. Comprehensive signal generation and analysis: Built-in 50MHz signal generator supports 14 standard waveforms plus custom waveform capability; the spectrum analyzer covers 200K–350MHz for EMI, RF, and high-frequency signal testing. Safety and charging: High-voltage protection up to 400V and QC18W fast charging enable safe operation and recharging within approximately two hours for extended use. Data management: Stores up to 500 waveform files and 90 images with USB export for further analysis and reporting. The DPOS350P delivers a balanced combination of measurement versatility, fast waveform capture, touchscreen convenience, and practical data export, making it suitable for lab bench use, field service, and development workflows.
