Digital Oscilloscope Note: The digital oscilloscope uses a 9V DC power supply (power supply voltage should not exceed 10V! Otherwise, there is a risk of burning the machine). The kit itself does not contain a power supply, the user needs to prepare their own power supply, power supply current should be able to provide more than 200mA.
