Features:
【3 In 1 Design with IPS Display】: This product ingeniously integrates digital oscilloscope, multimeter, and signal generator functions into one device. 3.2-inch clear-definition IPS display, high sensitivity full view display, channel 2 waveforms can be set to green/ cyan/purple.
【Signal Generator】: Built-in waveform signal generator, it can output sinewave, squarewave, trianglewave, and so on. The voltage amplitude is 2.5V, the frequency is adjustable from 0-2Mhz, and the squarewave duty cycle is adjustable from 1% to 99%.
【High-precise Multimeter】: Built-in true RMS multimeter, that supports quick software calibration. With DC/ACvoltage, DC/ACcurrent, resistance, capacitance, diode, and continuity test. When measuring low voltage /resistance/continuity, the oscilloscope and multimeter functions can be used simultaneously (small window in the upper right corner).
【Digital Oscilloscope Function】: Dual channel oscilloscope function, with 120MHz bandwidth and 250MSa/s sampling rate. With perfect trigger function (automatic, single, normal). Supports sensitivity and time base adjustment, automatic mode adjustment, 2-channel waveform analysis, cursor measurement, reference waveforms, FFT spectrum, reference waveforms, waveform save and view.
【Sensitivity and Time Base】: The oscilloscope will automatically detect the signal and adjusts the ranges. Support manual adjustment of the waveform vertically and horizontally. The vertical sensitivity indicates the voltage in the vertical direction, and it is adjusted by the mV and V buttons to adapt to different voltages. The time base represents the time in the horizontal direction. It is adjusted by the S and NS buttons to accommodate different frequencies. In the stop mode, the user can move the waveform left and right.
【Two Automatic Modes Adjustment】: Support one-button automatic and fully-automatic mode, no complicated operation, you can quickly detect and display the waveform. In fully automatic mode, no keystrokes are required, and continuous automation is performed.
【High Bandwidth & Sampling Rate】: The real-time sampling rate is 250MSa/s, dual-channel mode bandwidth is halved to 60Mhz.
【Dual Channel】: With dual-channel mode, which can measure and display two signal waveforms at the same time for waveform comparison and analysis.
【XY Mode for Cursor Measurement】: The XY mode is an imaging formed by combining the waveforms of two channels and is commonly used to display the phase difference or frequency relationship between two signals. Supports X cursor and Y cursor measurement. The horizontal cursor can be used, for example, to measure the interval time between two pulses. The vertical cursor can be used to measure the voltage and the voltage difference at any two locations.
【FFT Spectrum】: FFT (Fast Fourier Transform) is an algorithm that transforms waveforms in the time domain to the frequency domain, which can be used to analyze the frequency component in waveforms. Linear and logarithmic displays are supported. Note: FFT can only display spectrograms, frequency measurement is not supported.
【Reference Waveform】: Support for latching reference waveforms, statically displaying the current waveform on the screen, while the dynamic waveforms are continue to update normally. And can be used for reference and comparison between multiple waveforms.
【Waveform Save/View】: Save the screen waveform with one click, enter the picture browsing page, you can click the thumbnail for full-screen observation and also can delete the unwanted waveform chart at will.
【Safer Design】: Use an isolation transformer and isolation optocoupler chip to isolate the multimeter from the oscilloscope, so you don't have to worry about common ground wiring. (When measuring high voltage, the multimeter, and oscilloscope cannot be used at the same time).
【Wide Applications】: It can easily handle measurement in various fields, widely used in the fields of testing and debugging of electronic circuits, troubleshooting and repairing of elect
