Description
This multifunction device combines a dual-channel oscilloscope, multimeter, and waveform generator into one unit. It features a 3.5-inch high-resolution, high-contrast color LCD display, making it suitable for outdoor use.
The device is powered by an integrated 18650 lithium battery and includes a USB-C interface, supporting power bank charging and PC software connection.
Additionally, it has a self-calibration function and supports SCPI (Standard Commands for Programmable Instruments), facilitating secondary development.
