5. Configuração

5.1 Ligando o dispositivo

  1. Connect the USB Type-C power adapter to the oscilloscope's power input port.
  2. Conecte o adaptador de alimentação a uma tomada elétrica adequada.
  3. Press the power button located on the front panel to turn on the oscilloscope. The display will illuminate.

5.2 Conexão e Compensação da Sonda

  1. Connect a test probe to one of the BNC input channels (CH1-CH4) on the front panel.
  2. Attach the probe tip to the probe compensation output (usually a square wave signal output on the front or side).
  3. 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.
  4. Repeat this process for all probes you intend to use.

6. Instruções de operação

6.1 Basic Waveform Display

  • Seleção de canais: Press the CH1, CH2, CH3, or CH4 buttons to enable or disable a channel.
  • Vertical Scale: Use o Escala vertical knob to adjust the volts per division (V/div) for the selected channel.
  • Posição vertical: Use o Posição vertical knob to move the waveform up or down on the screen.
  • Horizontal Scale: Use o Escala horizontal knob to adjust the time per division (s/div).
  • Posição horizontal: Use o Posição horizontal knob to shift the waveform left or right.

6.2 Funções de disparo

The oscilloscope offers various trigger types to stabilize and capture specific parts of a waveform.

  • Pressione o Acionar botão para acessar as configurações do gatilho.
  • Select the desired trigger type (e.g., Edge, Pulse, Video) from the menu.
  • Adjust the trigger level using the dedicated Nível de desencadeamento 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.

  • Tocar: Select menu items, buttons, or adjust settings.
  • Ampliar com os dedos: Use two fingers to zoom in or out on waveforms (horizontal and vertical scaling).
  • Arrastar: Move waveforms or menu elements across the screen.

6.4 Data Storage and Connectivity

The DOV704 supports various methods for data storage and external connectivity.

  • USB: Connect a USB flash drive to save waveform data, screenshots, or settings. Use the USB cable to connect to a computer for data transfer.
