Today I received my FNIRSI DPOS350P, a 4-IN-1 350MHz 1GSPS Tablet Oscilloscope + Signal Generator + Spectrum Analyzer + Frequency Response Analyzer
Features
- Powerful multi-function integration: The DPOS350P combines a 350MHz oscilloscope, 50MHz signal generator, 200K~350MHz spectrum analyzer, and a 50MHz frequency response analyzer to meet various signal testing needs.
- High-performance waveform capture: With a 1GSPS real-time sampling rate, 350MHz analog bandwidth (single-channel mode), and an ultra-high 50,000 wfm/s waveform refresh rate, it can accurately capture and display low-probability anomaly signals.
- Fine display and operation: Equipped with a 7-inch 1024×600 high-resolution IPS touchscreen, it provides clear waveform display and supports grayscale and color temperature mode switching, making it easy to operate in different testing environments.
- Rich signal generation and analysis capabilities: The built-in 50MHz signal generator supports 14 standard waveforms and custom waveform functionality, while the spectrum analyzer covers a frequency range of 200K~350MHz, ideal for EMI, RF, and high-frequency signal testing.
- High-voltage protection and fast charging: The device has a high-voltage protection design up to 400V for safety, and with QC18W fast charging technology, it can be fully charged in 2 hours, ensuring long-term stable operation.
- 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.
