FNIRSI DSO510 2-in-1 Handheld Oscilloscope & DDS Signal Generator 10MHz

The FNIRSI DSO510 Handheld Oscilloscope & DDS Signal Generator is a compact 2-in-1 testing instrument designed for accurate signal analysis and generation in electronics repair, R&D, education, and hobbyist applications. Combining a 10MHz oscilloscope with a 0-50kHz signal generator, it delivers powerful functionality in a lightweight, portable design.

Equipped with a 2.8-inch TFT colour display (320×240), the DSO510 provides clear, real-time waveform visualization. Its 48MS/s sampling rate ensures reliable measurements of both periodic analog and non-periodic digital signals. A wide 400V voltage range, multiple trigger modes, and a one-click AUTO mode make operation fast and beginner-friendly.

The built-in DDS signal generator supports a wide range of waveform outputs, making this device ideal for testing, debugging, and educational demonstrations. Powered by a 1000mAh rechargeable lithium battery, it delivers up to 4 hours of continuous use, perfect for field work or on-the-go diagnostics.
