FNIRSI® DSO-510 10MHz 48MS/s Mini Handheld Digital Oscilloscope Signal Generator
Product Description
The FNIRSI® DSO-510 is a compact handheld digital oscilloscope with a built-in DDS signal generator, combining two useful electronic testing functions in one portable instrument. It is designed for electronics troubleshooting, circuit testing, maintenance, and educational applications.
The oscilloscope features a 10MHz bandwidth and a 48MS/s real-time sampling rate, with a single input channel for observing periodic analog signals and non-periodic digital signals. It supports AC/DC coupling, rising-edge and falling-edge triggering, and Auto, Normal, and Single trigger modes. Its one-click AUTO function automatically adjusts measurement parameters to help display waveforms quickly.
The integrated DDS signal generator supports 13 waveform types and an adjustable frequency range of 0–50kHz. Users can configure the output frequency, amplitude, and duty cycle for rectangular and sawtooth waveforms.
Featuring a 2.8-inch color LCD display, waveform scaling and movement functions, screenshot saving and exporting, and a built-in 1000mAh rechargeable lithium battery, the DSO-510 offers a convenient solution for portable electronics testing.
