DSO203 is a pocket size 4 channel digital oscilloscope for common electronic engineering tasks. It's based on ARM cortex M3 (STM32VCT6), providing 72MS/s sampling rate with integrated FPGA and high speed ADC. Internal 2MB USB disk could be used to store waveform, user application and upgrade firmware.


1) 2 probe connectors

2) 4 inputs & 4 tracks (2 analog 2 digital)

3) A custom waveform output (including the built-in sine, square, triangle)

4) Built-in 2M USB disk

5) Very low power consumption
