Mini Digital Oscilloscope

No tax

This digital oscilloscope has similar bandwidth as DSO138 but contains significant improvements in structure, mechanism and operation. It features high sensibility, light and portable size, 2.4-inch TFT screen and protective case. It can display waveform parameters, such as frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.


1. Adopts ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen

2. Used for secondary development on the basis of this kit, for example, it can be changed to millivoltmeter, data loggers.

3. Come with instructions, easy to install and operate.

4. Auto/normal/single trigger modes, easy to capture the moment waveform.

5. Available rising or falling edge trigger.

6. Observable previous waveform before trigger (negative delay).

7. Can freeze waveform display at any time (HOLD function).

8. Waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.

9. Waveform storage function: Will not lose the waveform after powering off.

10. Short-circuit and open-circuit detection: Can help the user find out the soldering error.

11. TFT controller recognition function.

12. The SMD has been soldered, more suitable for electronic beginners.
