DSO138 Portable Oscilloscope with Enclosure
The DSO138 is a portable signal measurement instrument based on an ARM Cortex-M3 (STM32F103C8), with a 2.4-inch colour TFT display at 320 × 240 pixels. A transparent enclosure is included. The listing says it displays waveform frequency, period, pulse width, duty cycle and max/min/average/peak-to-peak values.
Features stated in the listing
- Adjustable vertical position; manual included
- Auto, normal and single trigger modes
- Rising-edge or falling-edge trigger
- Previous-trigger waveform view with negative delay
- Hold/freeze the current waveform display
- 1Hz / 3.3V square-wave test signal
- Digital waveform measurements: frequency, period, pulse width, duty cycle, maximum, minimum, average and peak-to-peak values
- Waveform storage; the source says stored waveforms remain after power-off
- Short-circuit and open-circuit detection to help identify soldering errors
- TFT controller recognition
Use within the instrument’s input and measurement limits stated in its manual. Price: 390 MAD.
