Feature:1. Triple Functionality: Combine oscilloscope, multimeter, and waveform generator functionalities into a single, portable unit. The 3-in-1 Oscilloscope Multimeter Waveform Generator integrates three essential electronic testing tools into one compact, lightweight device. This triple functionality eliminates the need to carry multiple instruments, making it highly convenient for on-site work or field service. The built-in rechargeable battery ensures extended usage without being tethered to a power source.The maximum output frequency of the waveform can reach 100kHz, and it can output sine waves, rectangular waves, sawtooth waves, and pulse waves.2. High Precision Measurement: With a bandwidth of 70MHz and a real-time sampling rate of 250MSa/s, it can capture rapidly changing signals at a waveform refresh rate of up to10000 wfms/s, ensuring that no key details are missed Suitable for scenarios that require precise measurement, such as troubleshooting electronic circuits, on-site service, and maintenance. It can clearly display the signal waveform through the circuit, helping to identify issues such as voltage spikes or noise.3. Independent and Isolated Dual Function: integrating oscilloscope and multimeter tools, both of which are independent and electrically isolated from each other, allowing for simultaneous measurement of electrical signal values and waveforms, greatly improving work efficiency. Users can use these two functions separately without affecting the other function. Although the results cannot be displayed on the same screen at the same time, they can easily switch to view different measurement data.4. Automatic Settings & Multiple Measurement Modes: The built-in automatic setting function simplifies the operation process, supports cursor measurement and slow scanning mode, suitable for long-term monitoring of signal trends, especially useful for capturing slow or periodic waveforms. Multiple measurement options including but not limited to DC/AC voltage, resistance, capacitance, etc. are provided to meet the needs of different application scenarios.5. Intuitive and Convenient Operating Experience: Equipped with a 3.5-inch high-resolution color LCD display screen, providing clear data views and making reading easier; Support USB interface connection to the computer to save waveform images and data for subsequent analysis. After connecting to a PC via USB, it is easy to transfer the waveform images and data obtained from the test to the computer for further processing, improving work efficiency while ensuring professionalism.Specification:Item: 3in1 Oscilloscope Multimeter Waveform GeneratorColor: Black, BlueMain Material: ABSPartial Performance Parameters of OscilloscopeBandwidth: 70MHzChannel: 1 ChannelsReal Time Sampling Rate: 250MSa/sSampling Mode: Sampling, Peak, DetectionStorage Depth: 4K or 8KDisplay: 3.5-inch LCD (320*240) Waveform Refresh Rate: 10000 wfms/sInput Coupling: DC, AC, GNDInput Impedance: 1M ± 2%, Parallel with 16pF ± 10pFProbe Attenuation Coefficient: 1X, 10X, 100X, 1000X, 10000XMaximum Input Voltage: 400V (DC+AC, PK-PK)Sampling Rate Range: 0.25Sa/s250MSa/sWaveform Interpolation: (Sin x)/xTime Base Range: 5ns/div~1000s/div, Step by 1~2~5 BaseTime Base Accuracy: ±100ppmVertical Sensitivity: 10mV/div~10V/divPosition Range: ±2V(10mV/div–200mV/div) ±100V(500mV/div–10V/div)Low Frequency Response: ≥10Hz (AC Coupling, -3dB) Rise Time (Typical on BNC): ≤5nsDC gain accuracy: ±3%Trigger Type: Edge TriggerCoupling: DC, ACTrigger Type: Auto, Normal, SingleTrigger Level Range: ±4 div from the Center of the ScreenTrigger Level Accuracy: ±0.3 divTrigger Position: According to Record Length and Time BaseEdge Triggering: Rising Edge; Falling EdgeAutomatic Measurement: Period, Frequency, Mean, PK-PK, Max, Min, Amplitude, RMSCursor Measurement: V, TCommunication Interface: USB TYPE-CPower Supply: 2 * 3.7V Lithium BatteriesPart of the Performance Parameters of the Multimeter are StandardDisplay: 24,000 ReadingsMeasurement: Voltage, Current, Resistance, Capacitance, Continuity, DiodeDiode Test: 0-2VMaximum Input Voltage: AC 750VDC 1000VMaximum Input Current: AC 10ADC 10AAuto Range: √Continuity: <50Ture RMS: √Waveform GeneratorOutput FrequencySine: 10Hz~100kHz, Step by 1-2-5 Square: 10Hz~100kHz, Step by 1-2-5Ramp: 10Hz~100kHz, Step by 1-2-5 Pulse: 10Hz~10kHz, Step by 1-2-5 Amplitude: 1Vpp or 2.5VppSize: 19.8*9.6*3.8cm/7.8*3.78*1.5inchPackage Size: 24*15.8*9cmPackage Weight: 805gPackage List:1 * Oscilloscope1 * Probe Pen Calibration Pen2 * Multimeter Test Probe1 * Probe Pen1 * USB Data Cable1 * Instruction Manual1* Other Fittings
