3in1 convenient tool This device combines a digital oscilloscope, an electronic component tester, and a PWM generator in one unit for streamlined testing and prototyping. Oscilloscope performance The oscilloscope offers realtime sampling and a bandwidth of 500 kHz, enabling you to capture and analyze waveform details across common signal ranges. Voltage measurement Measure voltages up to 400V, making it suitable for a wide range of electronic projects and diagnostic tasks. Device identification and testing In oscilloscope mode, you can test and observe the waveform of the circuit under test. In MOS test mode, you can evaluate various types of transistors to identify device type, pin polarity, hFE, onstate voltage, junction capacitance, and inductive components, among other characteristics. Key benefits Allinone solution: combines oscilloscope, component tester, and PWM generator to reduce equipment clutter and simplify workflows. Quick component identification: helps verify transistor types, pinouts, and key electrical parameters without switching tools. Versatile testing capabilities: supports waveform analysis, component characterization, and PWM signal generation in a single device. Practical for a range of users: suitable for electronics hobbyists and professionals working on circuits that require rapid testing and iteration. Use scenarios Debug and validate a microcontroller PWM output: observe the signal shape and timing with the oscilloscope while using the PWM generator to produce test patterns. Identify unknown transistors on a board: switch to MOS test mode to determine device type, pin arrangement, hFE, and other relevant parameters. Prototyping and diagnostics of power or analog circuits: measure voltage levels up to 400V, capture waveform changes in real time, and characterize components as you iterate designs.
