Plastic housing material offers drop proof and shockproof properties. The printed circuit board uses an immersion gold process for high antioxidant corrosion resistance, stable working performance, and reliability. This product integrates digital oscilloscope, multimeter, and signal generator functions into one device. It features a 3.5-inch color display for clear screen readings and rich visual color. The user-friendly interface and operation mode allow for quick familiarization. Equipped with a built-in signal generator function featuring automatic waveform measurement and recognition. The high precise multimeter with true RMS measuring function supports tests of DC voltage, AC voltage, DC current, AC current, resistance, and capacitance. The oscilloscope has a real-time sampling rate of up to 280MS/s to capture signal details. The 50MHz bandwidth meets the testing needs of most electronic devices for both high-frequency and low-frequency signals. Additional functions include overclocking, afterglow mode, and XY mode. Full-grade overload protections include a built-in intelligent anti-burn chip and double ceramic fuses to prevent misuse. The built-in high-voltage protecting module helps prevent damage from high-voltage currents. Supports multiple waveform measurements and data storage. Condition: New. Origin: China.
