Product Description
The DSO150 Digital Oscilloscope Kit (Pre-Soldered) provides a cost-effective, high-utility diagnostic tool for electronic enthusiasts, educators, and field technicians. As an upgrade to earlier DSO models, the DSO150 features an improved power supply design and analog channel for better stability. 
This specific edition is “Pre-Soldered,” meaning all complex Surface Mount Devices (SMD) and the critical analog signal path components are professionally installed. Users only need to perform simple through-hole soldering for connectors and switches, making it an excellent educational project with a guaranteed functional outcome. Once assembled within its durable enclosure, the DSO150 offers reliable performance as a 0-200KHz bandwidth oscilloscope, perfect for audio, microcontroller (Arduino/Raspberry Pi), and power supply ripple measurements. 
Key Features
  • Guaranteed Success (Pre-Soldered): Core MCU and sensitive analog circuits are factory-soldered, reducing assembly errors and ensuring a functional device.
  • Intuitive 2.4″ TFT Display: Clear visualization of waveforms with automatic display of parameters like Frequency, Peak-to-Peak Voltage (Vpp), and Duty Cycle.
  • Wide Application: Ideal for STEM education, DIY electronics troubleshooting, and basic field maintenance where portability is key.
  • Digital Freeze Function: “Hold” mode freezes the waveform trace for detailed manual analysis.
  • High-Resolution Capture: 12-bit precision ensures better vertical accuracy than typical 8-bit entry-level scopes.
  • Built-in 1KHz/3.3V Test Source: Convenient for verifying probe integrity and self-testing the device. 
Usage & Assembly Guide
  1. Assembly (DIY – Through-Hole Only): Solder the provided through-hole components (BNC connector, push buttons, switches, power jack, and terminal blocks) onto the main PCB. Follow the included instructions carefully.
  2. Enclosure Assembly: Once soldering is complete, use the screws and acrylic panels to assemble the protective case.
  3. Powering On: Connect a stable 9V DC power source. The screen will display the interface.
  4. Calibration: Connect a BNC probe to the input. Attach the probe tip to the onboard 1KHz test signal pins. Adjust settings until a stable square wave appears on screen.
  5. Measuring: Adjust the vertical (Volts/Div) and horizontal (Time/Div) scales to capture your target signal effectively. Use the TRIG button to stabilize repetitive waveforms.
Q: Does this kit require advanced soldering skills?

No. This is the “Pre-Soldered” version, designed for beginners. The tiny surface-mount chips are already installed. You only need basic through-hole soldering skills (soldering wires and large connectors)

Q: Is a power supply included in the box?

No. You will need a regulated 9V DC power adapter (center positive, 200mA minimum required)

Q: Can I use this for measuring signals in highly complex digital circuits?

The DSO150 is best for analog and slow digital signals up to about 100KHz. For high-speed digital logic or protocols like I2C/SPI, you may require a higher bandwidth (e.g., 20MHz+) oscilloscope

Q: Is this suitable for business or educational bulk purchasing?

Yes. The “Pre-Soldered” aspect makes it ideal for educational labs, as it ensures functional success while still providing a hands-on assembly experience

Q: What is the benefit of 12-bit resolution?

The 12-bit resolution provides more detail and less quantization noise when measuring small vertical changes in your signal compared to cheaper 8-bit alternatives

Q: Can I use this with a rechargeable battery?

Yes, many users integrate a standard 9V battery or a custom LiPo battery setup, as the device is highly portable and has low power consumption.
