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

Features:

- It has an ARM Cortex-M3 processor (STM32F103C8) and a 2.4-inch color TFT display
- Auto/Normal/One time trigger modes, easy to capture the waveform of the moment.
- Available rising or falling edge trigger.
- Observed previous waveform before trigger (negative delay).
- You can stop the waveform display at any time (HOLD function).
- Digital display of waveform parameters including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.
- Waveform storage function: The waveform will not be lost after switching off.
- Short circuit and tear detection: It can help the user to find out the soldering error.
- TFT controller recognition function.
