1. Compact size, powerful performance: Combines a digital fluorescent oscilloscope, full-featured signal generator, spectrum analyser, and frequency response analyser in one unit.
2. High-voltage burn protection: The front-end input design features a high-voltage-resistant design, ensuring it can withstand over 400V at any setting without being damaged.
3. QC Fast Charging Function: Built-in 3.7V/8000mAh polymer lithium battery with integrated QC 2.0 protocol, supporting up to 18W charging. Fully charged, it can operate continuously for 3 hours.
4. High-Resolution Mode: Supports up to 16-bit resolution. High-resolution mode effectively removes noise components, offering optimal signal detection and display capabilities, aiding in the analysis of signal details and characteristics.
5. Dual-channel input design: Features two input channels with an input impedance of 1MΩ (18pF), enabling simultaneous measurement of two different signal groups.
6. One-button waveform screenshot saving: Built-in 1Gbit storage space, capable of storing up to 90 images or 500 waveform groups, allowing for secondary analysis of saved signals.
7. Full-featured signal generator: Can output 14 types of waveform signals, with adjustable output frequency up to 50 MHz, amplitude 0-5 V, offset +2.5 V, and duty cycle 0.1%-99.9%. Features a unique clipping output function, capable of storing up to 500 custom signals.
