FNIRSI® DSO-510 10MHz 48MS/S Mini Handheld Digital Oscilloscope Signal Generator

FNIRSI® DSO-510 10MHz 48MS/S Mini Handheld Digital Oscilloscope Signal Generator

Product Description

The FNIRSI DSO-510 is a compact 2-in-1 handheld instrument that combines a digital oscilloscope with a DDS signal generator, giving electronics engineers, students, and repair technicians two essential test tools in a single pocket-sized device. Built for both bench and field use, it's designed to make waveform capture and signal simulation accessible without the bulk or cost of separate benchtop equipment.

On the oscilloscope side, the DSO-510 delivers a 10MHz bandwidth with a 48MS/s real-time sampling rate, supporting both periodic analog signals and non-periodic digital signals across a time base range of 50ns to 20 seconds. Its voltage measurement range extends to ±400V, making it capable of handling everything from low-level signal work to higher-voltage automotive and appliance diagnostics. Three trigger modes, Auto, Normal, and Single, give users control over how the scope captures and holds waveforms, while a one-key AUTO function automatically optimizes measurement parameters for a fast, no-fuss initial reading. An infinite afterglow display mode helps capture transient or intermittent signal features that a standard refresh rate might miss, and the device supports waveform scaling, pausing, panning, and saving or exporting captured images for later review or documentation.

The built-in DDS signal generator adds a second layer of usefulness, outputting 13 different waveform types at frequencies up to 50kHz. This lets users generate test signals directly from the same device used to capture and analyze them, which is convenient for verifying circuit response, testing filters, or simulating input signals during repair and development work without needing a separate benchtop generator.

Results are shown on a 2.8-inch TFT display at 320×240 resolution, offering clear, easy-to-read waveforms even in a compact handheld form factor. The interface supports eight languages, including English, Russian, Japanese, Spanish, Portuguese, German, Korean, and Chinese, making it accessible to a broad range of users internationally. Power comes from a built-in 1000mAh lithium battery, rated for around four hours of continuous use, and charges through a USB Type-C port at 5V/1A, so the device is ready for extended field diagnostics without needing to stay plugged in.

Whether it's used for automotive signal diagnostics, appliance repair, embedded systems debugging, or classroom instruction in electronics fundamentals, the DSO-510's combination of solid oscilloscope specs and an integrated signal generator makes it a practical all-in-one tool for anyone who needs quick, portable waveform analysis without setting up a full lab bench.
