Feature: 1. [Handheld Oscilloscope] With 2.4 inch TFT 320x240 color LCD screen for clear and accurate waveform display. Single channel bandwidth up to 120MHz and dual channel up to 40MHz, with a 500MSps equivalent sampling rate. Comes with two 1X to 10X probes, can measure up to 800VPP, equivalent to 280V AC, and can measure voltages as high as ±400V. 2. [Professional Design] Features full triggering function (AUTO Normal Single). Suitable for periodic analog signals and non periodic digital signals. With Type C interface for data tranfer and charging and interface for directly updating firmware. Can store 2500 waveforms, with functions such as thumbnail browsing and waveform deletion. 3. [Versatile Signal Sources] The signal source has sine wave, triangular wave, and square wave waveforms, with multiple options for output amplitude, frequency, and square wave duty cycle. 4. [Single Click AUTO] Equipped with all parameters, waveform can be automatically adapted to the screen with single click, without the need to adjust parameters. The waveform parameters such as time base, amplitude, triggering slope, etc. can be set for quick and efficient testing. 5. [Longer Battery Life] The oscilloscope is equipped with 2000mAh lithium battery, which can be used continuously for about 8 hours after being full charged. Meanwhile, it is equipped with a Type C charging cable, the device can be used while charging, very convenient. 6. [Compact and Lasting] Compact and lightweight, easy to carry, can be used directly. The silicone protective covers on both sides of the machine make it anti slip, anti drop, and shockproof, providing a comfortable feel. 7. [Wide Application] Widely applicable to various applications such as household appliance inspection, scientific research and education, product development, and mains testing.
