PROFESSIONAL 3 IN 1 DESIGN It integrates the functions of digital oscilloscope, electronic component tester and PWM signal generator into one. It has 10MSa/s sampling rate, 500KHz bandwidth, testof voltage signal up to 400V and a complete trigger function (single, normal, automatic), the measured waveform can be displayed without tedious adjustment, easily adapts to measurement tests. 2.4-INCH HIGH-DEFINITION BACKLIT SCREENThis portable digital oscilloscope transistor tester is designed with a 2.4-inch high-resolution TFT screen with adjustable backlight. Best reading experience and easy to use.It can test different functions and support multi-interface screen display. With keyboard design, it is more convenient to operate and select different test function modes. IDENTIFY DEVICE TYPE Oscilloscope mode can test the circuit signal waveform, while Mos test mode can test different types of transistors, which can identify the device type, polarity of the pin, thehFE, state voltage, junction capacitance, resistance, inductive components, etc. In signal generator mode, you can use sine, pulse, triangle or ramp waveform, which can meet your needs of APPLICABLE ITEMSThis oscilloscope probe kit supports PC online operation, which is especially suitable for rapid transistor matching, identification of mixed face-mount and wireless components. wordsand initial screening of components in small batches. It can automatically identify and measure various transistors, including NPN and PNP transistors, diodes, double diodes, etc.
