Describe The device is equipped with three main functions: oscilloscope, multimeter and signal generator. The oscilloscope adopts FPGA+MCU+AD.C hardware architecture, with a sampling rate of 50MS/s, 10Mhz analog bandwidth, built-in high-voltage protection module, and supports maximum ±400V peak voltage measurement; Supports saving and viewing waveform screenshots for analysis. The multimeter has a 4-digit 10,000-point true effective value and supports AC and D.C voltage and current measurements, as well as capacitance, resistance, diode, continuity and other measurement functions. It is an ideal multifunctional instrument whether used by professionals, factories, schools, hobbyists or at home. The built-in DDS function signal generator can output 7 kinds of function signals. The maximum output of all signals is 2MHz, with a step of 1Hz; the output frequency, amplitude and duty cycle are adjustable. It uses a 2.8-inch 320*240 resolution high-definition LCD display and a built-in 3000mAh rechargeable lithium battery with a standby time of up to 6H. It provides users with more and stronger practical functions in a compact size, while also being highly portable.
