Features: 1. Dual-channel 100MHz high-performance oscilloscope: Equipped with a sampling rate up to 500MSa/s and 100MHz analog bandwidth (50MHz per channel when both channels are active), featuring 10K/100K/1M memory depth to effortlessly capture complex and transient signals. 2. 4.3-inch capacitive touchscreen + physical buttons: Combines a 4.3-inch HD touchscreen with physical knobs for intuitive operation. Supports 128-level grayscale display with afterglow and color temperature adjustment for enhanced waveform viewing, enabling clear and intuitive waveform visualization. 3. Built-in 10MHz Signal Generator: Outputs 9 waveform types including sine, square, triangle, DC, noise, and step signals. Adjustable amplitude and duty cycle make it ideal for circuit simulation and testing applications. 4. Integrated True RMS Multimeter: 4½-digit (20,000 counts) true RMS measurement. Supports AC/DC voltage and current, resistance, capacitance, temperature, diode, and continuity testing—a versatile all-in-one tool. 5. Portable Design with Smart Features: Built-in 5000mAh rechargeable battery with Type-C fast charging. Includes auto power-off, screen brightness control, audible/visual alarms, self-calibration, waveform screenshot saving, and USB data export.
