⚙️ Core Features & Specifications:

? All-in-One Convenience for Electronics Testing:

✅ Digital Oscilloscope (50MHz)

Capture and analyze voltage signals in real time with a 250MS/s sampling rate. Perfect for visualizing waveforms, detecting signal distortion, or troubleshooting circuits in embedded systems, power supplies, or communication devices.

✅ True RMS Multimeter

Measure AC/DC voltage, current, resistance, and continuity with high accuracy. The multimeter mode features auto/manual ranging, buzzer alert, and overload protection – suitable for both low-voltage electronics and industrial applications.

✅ Signal Generator

Quickly generate test signals across a wide frequency range. Useful for circuit stimulation, waveform simulation, or injecting signals into amplifiers, filters, and logic circuits during prototyping or repair work.
