5. Configuración
5.1 Encendido del dispositivo
- Connect the USB Type-C power adapter to the oscilloscope's power input port.
- Conecte el adaptador de corriente a una toma de corriente adecuada.
- Press the power button located on the front panel to turn on the oscilloscope. The display will illuminate.
5.2 Conexión y compensación de la sonda
- Connect a test probe to one of the BNC input channels (CH1-CH4) on the front panel.
- Attach the probe tip to the probe compensation output (usually a square wave signal output on the front or side).
- Adjust the probe compensation screw (located on the probe body) until the square wave displayed on the screen has flat tops and bottoms, without overshoot or undershoot.
- Repeat this process for all probes you intend to use.
6. Instrucciones de funcionamiento
6.1 Visualización básica de forma de onda
- Selección de canal: Press the CH1, CH2, CH3, or CH4 buttons to enable or disable a channel.
- Escala vertical: Utilice el Escala vertical knob to adjust the volts per division (V/div) for the selected channel.
- Posición vertical: Utilice el Posición vertical knob to move the waveform up or down on the screen.
- Escala horizontal: Utilice el Escala horizontal knob to adjust the time per division (s/div).
- Posición horizontal: Utilice el Posicion horizontal knob to shift the waveform left or right.
6.2 Funciones de activación
The oscilloscope offers various trigger types to stabilize and capture specific parts of a waveform.
- Presione el Desencadenar Botón para acceder a la configuración del disparador.
- Select the desired trigger type (e.g., Edge, Pulse, Video) from the menu.
- Adjust the trigger level using the dedicated Nivel de disparo knob or via the touchscreen.
- Choose the trigger source (CH1-CH4) as needed.
6.3 Touchscreen and Gesture Control
The 7-inch touchscreen allows for intuitive control.
- Grifo: Select menu items, buttons, or adjust settings.
- Pellizcar para hacer zoom: Use two fingers to zoom in or out on waveforms (horizontal and vertical scaling).
