Osciloscópio mini portátil 2-em-1 e gerador de sinal Fnirsi DSO510 — largura de banda 100 MHz, taxa de amostragem 1 GS/s

The FNIRSI DSO510 is a portable 2-in-1 oscilloscope and signal generator with a 10 MHz bandwidth that combines compact size with useful measurement and signal output functions. The handheld device includes automatic adjustment, trigger level display, image recording and an adjustable afterglow for tracking transients. A built-in generator provides 13 waveforms. The unit is powered by a 1000 mAh rechargeable battery and is charged via USB-C.

Advantages

The device supports auto-adjust, trigger-level visualization and image storage, which simplify capturing and documenting signals. It has an adjustable afterglow to follow dynamic waveforms and supports freezing, zooming and panning for detailed waveform analysis. The integrated signal generator with 13 waveform types helps with testing and learning. Compact dimensions and a foldable stand enable hands-free use in the field.

Suitable for

• Basic electronics troubleshooting and hobby projects
• Field diagnostics and measurements where portability is required
• Educational use and hands-on learning with oscilloscopes
