For drone builders, it provides an immediate visual readout of PWM signals, ESC outputs, and voltage noise, helping troubleshoot flight controller or receiver communication issues without requiring a bulky desktop scope.
Key features
- Compact 2.4-inch TFT display for clear waveform readouts on crowded workbenches.
- Integrated PWM signal generator (1Hz to 80kHz) for testing servos, LED circuits, and simulating flight controller signal inputs.
- Supports Auto, Normal, and Single trigger modes with rising and falling edge options.
- Single-button auto-setup adjusts the time base and vertical scale automatically to display the measured signal.
