Oscilloscope Core Capabilities
10MHz Dual-Channel Oscilloscope
Comprehensive Waveform Adjustment
–Vertical System: Adjustable voltage ranges with support for X1/X10 probe attenuation matching.
–Horizontal Time Base: Adjustable time base. Low-speed signals automatically enter Roll Mode for extended observation of slowly changing waveforms.
Advanced Trigger System
Supports Auto, Normal, and Single trigger modes. Rising-edge and falling-edge triggering with freely adjustable trigger level and trigger source (CH1/CH2).
Rich Measurement Functions
–Automatic Measurements: Peak, Maximum, Minimum, Peak-to-Peak, RMS, Frequency, Duty Cycle, and Period. Up to 4 parameters can be displayed per channel.
–Cursor Measurements: Horizontal, vertical, and combined cursors for measuring voltage differences and time differences.
–XY Mode: For phase and frequency-ratio comparison.
–Adjustable Persistence: Minimum / 500ms / 1s / 10s / Infinite persistence for observing waveform changes and drift.
Waveform Storage & Export
-Long-press the button to save waveform screenshots for on-device viewing.
-Connect to a computer via Type-C to access the storage folder and export waveforms for PC-based analysis.
Practical Auxiliary Functions
–AUTO Setup: One-touch adaptation to unknown waveforms.
–Baseline Self-Calibration: Eliminates baseline offset caused by temperature changes or prolonged storage.
–Display & Power Management: Configurable backlight brightness, automatic backlight shutoff, and automatic power-off for optimal visibility and battery life.
–Multi-Language Support: Chinese, English, French, German, Russian, Spanish, Dutch, Turkish, and Portuguese. Factory reset supported.
Probe Compensation & High-Voltage Safety
Probe compensation detection mechanism ensures measurement accuracy, with comprehensive high-voltage safety warnings.
Built-in Signal Generator
Six Output Waveforms: Outputs 6 waveform types: Sine Wave, Square Wave, Triangle Wave, Half-Wave, Full-Wave, and Sawtooth Wave.
Adjustable Output Parameters: Output amplitude, frequency, and duty cycle can be independently configured. Supports on/off output control, with a built-in waveform preview window on the screen.
Common Ground with Oscilloscope: Shares a common ground with the oscilloscope, making it suitable for equipment debugging and circuit testing.
Digital Multimeter
Comprehensive Measurement Functions: Measures AC/DC Voltage, AC/DC Current, Resistance, Continuity with Audible Buzzer, Diode, Capacitance, and VFC AC Measurement with Interference Rejection.
Auto/Manual Range Selection: Supports both automatic and manual range switching. Features a data HOLD function that simultaneously displays MAX (Maximum Value), MIN (Minimum Value), and AVG (Average Value).
REL Relative Measurement: Supports REL relative value measurement. The AC range also provides frequency readings. Dedicated 10A and mA current input terminals are provided with fuse protection.
High-Definition Digital Display: Provides clear digital readings with flexible automatic or manual range selection.
