The FNIRSI DSO510 is a pocket-sized digital oscilloscope with a built-in signal generator.
Two essential tools in one compact device that fits in your hand.
Digital Oscilloscope
Capture and Analyse Signals
10MHz bandwidth handles audio, microcontroller and general electronics signals.
48MSa/s real-time sampling rate captures waveform detail accurately.
Suitable for both periodic analog signals and non-periodic digital signals.
Wide Voltage Range
Measurement range of ±400V.
Handles low-voltage circuits through to higher voltage applications.
Use the included probe for safe measurement.
Trigger Modes
Auto – continuously updates the display
Normal – triggers only when signal meets conditions
Single – captures one event then stops
Choose the right mode for stable waveform capture.
One-Click AUTO
Press one button and the oscilloscope sets up automatically.
Displays the waveform without manual adjustments.
Quick and easy for users of all experience levels.
Built-in Signal Generator
50kHz signal generator included.
Generate test signals without carrying a separate instrument.
Useful for testing amplifiers, filters and other circuits.
Clear Display
2.8-inch HD LCD screen.
Resolution of 320 × 240 pixels.
Waveforms and measurements shown clearly.
Readable in various lighting conditions.
Portable and Battery Powered
Built-in 1000mAh lithium battery.
Up to 4 hours of continuous use on a single charge.
No mains power needed.
Take it to the bench, the field or the classroom.
Compact Size
Fits in your pocket or toolkit.
Lightweight and easy to carry.
Perfect when you need an oscilloscope but don’t want to carry a full-sized unit.
Who Is This For?
Electronics hobbyists debugging circuits on the go.
Students learning about waveforms and signal analysis.
Repair technicians who need a portable scope for diagnostics.
Makers working on Arduino, Raspberry Pi and DIY projects.
