This product ingeniously integrates digital oscilloscope, electronic component tester, PWM signal generator and other functions into one. Equipped with large-size color dot matrix TFT display. Built-in rechargeable lithium battery. Bring more practical functions to users with a small size. If you are interested in this product, come and have a try, it will not let you down. Features: 2 In 1 Function: This product ingeniously integrates digital oscilloscope, electronic component tester, PWM signal generator and other functions into one. This product is especially suitable for fast pairing of transistors, identification of mixed surface mount and wordless components, and preliminary screening of small batch components. The oscilloscope has a real-time sampling rate of 2.5MS/s and a 200kHz bandwidth. With complete trigger function (Single, Normal, Automatic), it can be used freely for both periodic analogs signals and aperiodic digital signals. Up to ±400V voltage signal can be measured, has a wide applications. Equipped with efficient one-key AUTO, the measured waveform can be displayed without cumbersome adjustment. Self-contained 80kHz /5.0V PWM waves test signal source with adjustable duty cycle. This instrument can automatically identify and measure various transistors. Including NPN  transistors, N-channel and P-channel field effect transistors, junction field effect transistors, diodes, double diodes, thyristors, etc.,and passive component such as resistors, inductors, capacitors, etc Automatic detection of pin definitions.
