Features: This device is equipped with three main functions oscilloscope, multimeter, and signal generators. The Oscilloscope adopts FPGA+MCU+ADC hardware architecture, with a sampling rate of 50MS/s, 10Mhz analog bandwidth, built-in high-voltage protect module, most support measurement of peaks voltage of ±400V; Support for saving and viewing waveform screenshots for analysis. The multimeter has a 4digit 10000-point true effective value and supports ACDCvoltage and current measurement, as well as capacitance, resistance, diode, on/off, and other measurement functions. Whether used by professionals, factory, schools, enthusiasts, or families, it is an multi-functional instrument. Equipped with a built-in DDS function signal generators, it can output 7 types of function signals, with a most output of 2MHz for all signals and a step of 1Hz; The output frequency, amplitudes, and duty cycle are adjustable. Using a 2.8inch 320x240 resolution high-definition LCD screen with a built-in 3000mAh rechargeable battery, the standby time can reach up to 6H. Provides users with more and strong practical functions in a compact size, while also having good portability.
