- 10MHz analog bandwidth oscilloscope with 48MSa/s real-time sample rate and 1MΩ input impedance.
- 2.8-inch TFT color display with adjustable backlight brightness for clear waveform and data visualization.
- AC/DC coupling with vertical sensitivity from 10mV/div to 10V/div and horizontal time base from 50ns to 20s per division.
- Three trigger modes (Auto, Normal, Single) with selectable rising or falling edge detection.
- Automatic waveform measurements including max, min, average, RMS, peak-to-peak, frequency, period, and duty cycle.
- Waveform freeze (HOLD) function for detailed post-capture analysis and screenshot storage.
- 13-waveform DDS signal generator with 0-50kHz frequency range and 0.1-3.0Vpp adjustable amplitude.
