DIY Oscilloscope Kit DSO138

The DSO138 Oscilloscope Kit is a comprehensive package that comes with an ARM Cortex-M3 processor (STM32F103C8) and a 2.4-inch color display. This versatile kit is not only suitable for ARM testing but also for development purposes.There are numerous possibilities for additional features and customizations with this kit. For example, it can be modified into a data logger capable of recording signals at the millivolt level.

Functions and Features

• Adjustable vertical axis data flow.
• Diverse measurement modes: automatic, periodic, and single-measurement modes for detailed waveform analysis.
• Trigger modes include falling and rising edge triggers.
• Capability to display previous waveforms on the screen with negative delay.
• Waveform snapshots can be paused at any moment with the HOLD function.
• Incorporated 1Hz / 3.3V square wave test signal.
• Digital display of waveform parameters such as frequency, period, pulse width, duty cycle, and MAX/MIN/AVG/Peak-to-Peak/virtual values.
• Waveform storage function to prevent signal loss during power interruptions.
• Short-circuit and open-circuit detection to assist in identifying soldering mistakes.
• TFT controller recognition function.
