Ideal multifunctional instrument for professionals, factories, schools, enthusiasts, or families. Oscilloscope features a FPGAMCUADC hardware architecture with a sampling rate of 50 MS/s and an analog bandwidth of 10 MHz; it includes a builtin voltage protection module and can measure peak voltages up to ±400 V. Builtin DDS function signal generator provides 7 types of function signals; maximum output is 2 MHz for all signals with 1 Hz step increments; output frequency, amplitude, and duty cycle are adjustable. Supports saving and viewing waveform screenshots for analysis. Multimeter functions include a 4digit 10000 point true effective value display and support for AC/DC voltage and current measurement, as well as capacitance, resistance, diode, on/off and other measurement functions. Use scenario: electronics lab or bench where you need to verify circuit behavior, capture waveforms, and perform precise measurements in a compact setup. Use scenario: classroom or training environment for handson learning with signal generation, waveform analysis, and multiparameter measurements. Use scenario: field maintenance or onsite diagnostics in industrial settings, combining oscilloscope view with meter readings to quickly identify faults and verify system performance.
