5.1 Conexão de Energia

1. Certifique-se de que a chave de alimentação do osciloscópio esteja na posição DESLIGADO.
2. Conecte o cabo de alimentação fornecido à entrada de alimentação CA no painel traseiro do osciloscópio.
3. Conecte a outra extremidade do cabo de alimentação a uma tomada elétrica CA aterrada.

5.2 Conexão e Compensação da Sonda

1. Connect a passive probe to one of the CH1 or CH2 BNC input connectors.
2. Set the probe attenuation switch (if applicable) to 10X.
3. Connect the probe ground clip to the oscilloscope's ground terminal (usually a dedicated terminal or the ground ring of the BNC connector).
4. Connect the probe tip to the probe compensation output (usually a square wave test signal output on the front panel).
5. Ligue o osciloscópio.
6. Pressione o AJUSTE AUTOMÁTICO button. The oscilloscope will automatically adjust settings to display the compensation signal.
7. Ajuste o parafuso de compensação na sonda até que uma onda quadrada de topo plano seja exibida na tela. Isso garante medições precisas.

6. Instruções de operação

6.1 Basic Waveform Display

1. Ligue o osciloscópio.
2. Connect a compensated probe to CH1.
3. Connect the probe tip to the signal source you wish to measure.
4. Pressione o AJUSTE AUTOMÁTICO botão. O osciloscópio ajustará automaticamente as configurações vertical, horizontal e de disparo para exibir uma forma de onda estável.
5. Use o VOLTS / DIV knob to adjust the vertical scale (ampsolidão).
6. Use o SEG/DIV knob to adjust the horizontal scale (time base).
7. Use o POSIÇÃO Botões para mover a forma de onda verticalmente ou horizontalmente.

6.2 1MΩ/50Ω Impedance Switching

The DSO2D50 supports switching between 1MΩ (high impedance) and 50Ω (low impedance) input impedance. This is crucial for adapting to different measurement scenarios and ensuring signal integrity, especially for high-frequency signals or when matching transmission lines.
