DSO 138 2.4in TFT 1MSPS Digital Oscilloscope Kit Assembled Handheld Pocket Oscilloscope Board with Probe 12Bit 0-200KHz ARM Cortex-M3 Waveform Test Development Kit
- 2.4-inch TFT handheld digital oscilloscope kit with a 1Msps maximum real-time sampling rate for observing electronic waveforms.
- Features 12Bit accuracy, a 1024-byte sampling buffer depth, and an analog bandwidth range of 0-200KHz.
- Adjustable vertical sensitivity from 10mV/Div to 5V/Div in a 1-2-5 progression, with adjustable vertical displacement.
- Supports DC, AC, and GND coupling modes, with a horizontal time base range of 10s/Div to 50s/Div.
- Accepts a maximum input voltage of 50Vpp with a 1:1 probe or 400Vpp with a 10:1 probe.
- Includes automatic, regular, and one-shot modes, plus rising-edge and falling-edge trigger selection for waveform capture.
- HOLD function freezes the waveform display, while negative delay allows viewing the waveform before the trigger point.
- Built-in 1Hz/3.3V square-wave test signal source provides a ready signal for testing and observation.
- Digital waveform readout displays frequency, period, pulse width, duty ratio, MAX, MIN, AVG, peak-to-peak, and virtual values.
- Includes an assembled DSO 138 digital oscilloscope board, a probe, and 3 English user manuals; stored waveforms remain after power off.

Product Description:
Pocket-size digital oscilloscope kit with a 2.4-inch TFT display, 1MSPS real-time sampling rate, DIY parts, and probe. Designed as a handheld electronic learning set for waveform observation and hardware development.
Core Selling Points:
The assembled oscilloscope board uses an ARM Cortex-M3 processor and supports automatic, regular, and one-shot capture modes. HOLD function freezes waveform display when needed. Rising- or falling-edge triggering and negative delay allow observation of pre-trigger waveforms. Built-in 1Hz/3.3V square-wave test signal source. Digital waveform readouts include frequency, period, pulse width, duty ratio, MAX, MIN, AVG, peak-to-peak, and virtual values. Waveform storage retains saved waveforms after power off. Adjustable vertical displacement and partially open-source hardware support further feature development.
