Features 3 in 1 Design with IPS Screen: This product integrates digital oscilloscope, multimeter, and signal generator into one device. 3.2in clear IPS display screen, high sensitivity full view display, channel 2 waveform can be set to green, cyan, purple. Signal Generator: Built in waveform signal generator, capable of outputting sine wave, square wave, triangular wave, etc. The voltage amplitude is 2.5V, the frequency is adjustable between 0‑2Mhz, and the square wave duty cycle is adjustable between 1%. High Accuracy Multimeter: Built in true effective value multimeter, supporting software rapid calibration. Able to test DC AC voltage, DC AC current, resistance, capacitance, diode, and on off. When measuring low voltage, resistance, continuity. Digital Oscilloscope: Dual channel oscilloscope, with a bandwidth of 120MHz, and a dual channel mode bandwidth halved to 60Mhz. The sampling rate is 250MSa/s. With perfect triggering function of automatic, single shot, normal. Sensitivity and Time Base: The oscilloscope will automatically detect the signal and adjust the range. Support manual adjustment of waveforms in both vertical and horizontal directions.
