Features: High sensitivity, DSO150 oscilloscope sensitivity can reach 5mV/Div- at the high end and 20V/Div- at the low end. Data transmission can be realized through serial-port and PC connections. Using a coding-switch, parameter adjustment is more convenient and-fast. Suitable for DIY enthusiasts or school electronic competitions. Note: The product does not include power-supply! 9V power-supply.
