Features 3 in 1 design with IPS screen: This product integrates a digital oscilloscope, a multimeter and a signal generator in one device. 3.2 inch clear IPS display screen, high sensitivity full display, channel 2 waveform can be set to green, cyan, purple. Signal generator: Built-in waveform signal generator, capable of producing sine wave, square wave, triangle 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%. A High-precision multimeter: Built-in RMS multimeter, supporting rapid software calibration. Capable of testing AC DC voltage, AC DC current, resistance, capacitance, diode and shutdown. When measuring low voltage, resistance, continuity, the osci Digital Oscilloscope: Dual-channel oscilloscope, with a bandwidth of 120 MHz and dual-channel mode bandwidth halved to 60 MHz. The sampling rate is 250 MSa/s. With automatic perfect trigger function, single shot, normal. Sensitivity and time support Sensitivity and Time Base: The oscilloscope will automatically detect the signal and adjust the range. Supports manual adjustment of waveforms in vertical and horizontal directions. Vertical sensitivity represents the tension in the vertical direction Feature: 1. Two automatic adjustment modes: Support one-button automatic and fully automatic modes, enabling rapid detection and display of waveforms without complex operations. In fully automatic mode, continuous automatic operation can be achieved without buttons. XY mode is an imaging system formed by combining the waveforms of two channels, commonly used to display the phase difference or frequency relationship between two signals. Supports X and Y cursor measurements. 2. Other functions: FFT is an algorithm that transforms time domain waveforms into frequency domains, which can be used to analyze the frequency components of waveforms. Supports linear and logarithmic displays. Supports reference waveform lock, displaying the current waveform statically on the screen, while the dynamic waveform continues to update normally. And can be used for reference and comparison between multiple waveforms. Record screen waveform in 1 click and go to image browsing page. You can click the thumbnail for full-screen observation or delete unnecessary waveform images at will. Use an isolation transformer and an isolation optocoupler chip to isolate the multimeter from the oscilloscope, so you don't have to worry about common ground wiring problems. When measuring high voltage, a multimeter and an oscilloscope cannot be used simultaneously.
