4. Configuração

Follow these steps to set up your DSO-2104 oscilloscope for initial use:

1. Desembalagem: Carefully remove the oscilloscope and all accessories from the packaging. Verify that all components are present and undamaged.
2. Conexão de energia: Connect the provided power cable to the power input on the rear panel of the oscilloscope and then to a suitable AC power outlet (100-240V, 50/60Hz). Ensure the power outlet is properly grounded.
3. Conexão da sonda: Connect the oscilloscope probes to the desired BNC input channels (CH1, CH2, CH3, CH4) on the front panel. Ensure a secure connection.
4. Compensação da sonda: Before taking measurements, it is recommended to compensate your probes. Connect the probe to the probe compensation output (usually a square wave signal) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.
5. Ligar: Press the power button, typically located on the front panel, to turn on the oscilloscope. The display will illuminate, and the system will boot up.

5. Instruções de operação

The DSO-2104 offers a range of functions for waveform analysis. Here are basic operating guidelines:

5.1 Medidas Básicas

• Largura de banda: The device operates at a 100 MHz bandwidth across 4 channels.
• SampTaxa de ling: O máximo sampling rate is 1 GSa/s, allowing for detailed capture of fast signals.
• Resolução vertical: With an 8-bit vertical resolution, the oscilloscope provides good precision for voltage medições.
• Mostrar: Waveforms are displayed on the 7-inch (17.78 cm) LCD screen (800 x 480 pixels).

5.2 Adjusting Waveforms

• Escala vertical (Volts/Div): Use the vertical control knobs for each channel (CH1-CH4) to adjust the voltage scale, changing the vertical amplitude of the displayed waveform.
• Posição vertical: Use the position knobs to move the waveform vertically on the screen.
• Escala horizontal (tempo/divisão): Use the horizontal control knob to adjust the time base, changing the horizontal compression or expansion of the waveform.
• Posição horizontal: Use the horizontal position knob to shift the waveform left or right.

5.3 Acionamento

O disparo estabiliza formas de onda repetitivas e captura eventos de disparo único.

• Nível de desencadeamento: Ajuste o botão de nível do gatilho para definir o volume.tage point at which the oscilloscope will trigger.
• Modo de gatilho: Select different trigger modes (e.g., Edge, Pulse, Video) using the dedicated trigger buttons or menu.
• Frequency Counting: The oscilloscope includes a frequency counting function for precise frequency measurements.

5.4 Armazenamento e Recuperação de Dados

• Interface USB: The integrated USB port allows for convenient data storage. You can save waveform data, screenshots, and settings to a USB flash drive.
• Signal Curve Memory: The DSO-2104 can store up to 16 signal curves, which can be displayed on a PC in real-time for further analysis.

6. Manutenção

Proper maintenance ensures the longevity and optimal performance of your oscilloscope.

• Limpeza:
  • Sempre desconecte o cabo de alimentação antes de limpar.

7. Solução De Problemas

This section addresses common issues you might encounter with your DSO-2104 oscilloscope. If the problem persists, contact customer support.

7.1 Sem energia

• Verifique o cabo de alimentação: Certifique-se de que o cabo de alimentação esteja firmemente conectado tanto ao osciloscópio quanto à tomada elétrica.
• Verifique a tomada elétrica: Verifique se a tomada está funcionando conectando outro aparelho.
• Verifique o fusível: If applicable, check the power fuse (refer to the device label for fuse specifications and replacement instructions, if user-replaceable).

7.2 Nenhuma forma de onda exibida

• Verifique a conexão da sonda: Ensure probes are correctly connected to the input channels and the circuit under test.
• Check Channel Enable: Verify that the desired input channel is enabled on the oscilloscope.
• Adjust Vertical Scale: The waveform might be off-screen. Adjust the Volts/Div knob to a suitable range.
• Adjust Horizontal Scale: The waveform might be too compressed or expanded. Adjust the Time/Div knob.
• Check Trigger Settings: Incorrect trigger settings can prevent a stable waveform display. Try "Auto" trigger mode or adjust the trigger level.
• Botão Iniciar/Parar: Ensure the oscilloscope is in "Run" mode (not paused).

7.3 Forma de onda instável

• Adjust Trigger Level: Fine-tune the trigger level to a stable point on the waveform.
• Select Correct Trigger Type: Choose the appropriate trigger type (e.g., Edge, Pulse) for your signal.
• Check Probe Compensation: Improperly compensated probes can lead to distorted waveforms. Perform probe compensation if necessary.
