DSO138 Mini Version:
Description:
DSO138mini makes the following improvements:
1. Improved structure and smaller size
2. Powered by USB or battery.
3. External trigger input.
4. Serial data output signals.
5. Shared controller.
DSO138mini makes the MCU and lcd remain in the same circuit board to avoid the problematic pin header connections that were used in the DSO138. This not only improves product reliability, but also allows the main board to become a flexible general purpose controller.
DSO138mini's trigger can reliably work under timebase 10us and 20us settings. Waveform data can be disabled via the Serial port, and data can be easily displayed on a PC using other software like Gnuplot. This photo shows the same waveform as on a PC using Gnuplot.
