2. Guia de configuração
Follow these steps to set up your Hantek DSO4084B oscilloscope:
- Desembalagem: Carefully remove the oscilloscope and all accessories from the packaging. Verify all components are present against the packing list.
- Conexão de energia: Connect the power adapter to the oscilloscope's power input and then to a suitable power outlet.
- Conexão da sonda: Connect the oscilloscope probes to the BNC input channels (CH1, CH2, CH3, CH4) as needed for your measurements. Ensure a secure connection.
- Ligar: Press the power button located on the front panel to turn on the oscilloscope. The device will perform a self-test and display the Hantek logo.
- Exibição inicial: Upon startup, Channel 1 (CH1) will typically be active, displaying a horizontal line.

3. Instruções de operação
The Hantek DSO4084B offers intuitive controls for various measurement tasks.
3.1. Basic Waveform Adjustment
- Vol de ajustetage: Use the vertical scale knobs (labeled "Vertical") for each channel to adjust the voltage per division (V/div). The button next to the knob allows for fine-tuning the voltage.
- Adjusting Waveform Position: Use the position knobs for each channel to move the waveform vertically on the screen.
- Enabling Multiple Channels: All four channels can be activated simultaneously. Use the dedicated buttons for each channel (CH1, CH2, CH3, CH4) to toggle them on or off. Adjust voltage and position for each active channel independently.
- Configuração automática: Pressione o AUTO button to automatically adjust the oscilloscope settings for a stable waveform display. For example, when measuring a DC 5V signal, the auto function might set the display to 2V per division.
3.2. Funções de Medição
The oscilloscope provides extensive measurement capabilities:
- Medições Automáticas: Access over 32 types of automatic measurements by pressing the MEDIDAS button. This displays parameters like Vpp (peak-to-peak voltage), Vmax, Vmin, frequency, period, and more. Pressing MEDIDAS again will hide the measurement results.
- Sistema de gatilho: Utilize the advanced digital trigger system with over 14 types of trigger functions (edge, overtime, pulse, pattern, interval, etc.) to capture specific events.
- Decodificação do barramento serial: For serial bus protocols, the device can quickly and intuitively display bus protocol information in table form.
3.3. Coupling Settings (DC/AC)
To accurately measure different signal types, adjust the coupling setting:
- DC Coupling: Select DC coupling (usually via a menu accessed by a function button like F1) to measure both AC and DC components of a signal.
- Acoplamento CA: Select AC coupling to block the DC component and only display the AC component of a signal. This is useful for observing small AC signals superimposed on a large DC offset.
- Limite de banda larga: The oscilloscope features a 20MHz bandwidth limit option (e.g., BW 20M). Activating this can help remove high-frequency noise or unwanted signals above 20MHz, providing a cleaner waveform for analysis.
- Adjusting Time Base: Use the horizontal scale knob (labeled "Horizontal") to adjust the time per division (s/div) to view mais ou menos da forma de onda na horizontal.

4. Manutenção
Proper maintenance ensures the longevity and accuracy of your Hantek DSO4084B oscilloscope:
- Limpeza: Regularly clean the exterior of the oscilloscope with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth with mild detergent. Avoid abrasive cleaners or solvents.
- Cuidados com a tela: Use a soft, lint-free cloth specifically designed for electronics screens to clean the display. Do not press hard or use harsh chemicals.
- Ventilação: Certifique-se de que as aberturas de ventilação estejam livres de poeira e obstruções para evitar o superaquecimento.
- Armazenar: When not in use, store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and excessive humidity.
- Cuidados com a sonda: Handle probes carefully. Avoid bending or stressing the cables. Store them properly to prevent damage to the tips and connectors.
- Calibração: For critical measurements, periodic calibration by a qualified service center is recommended to maintain accuracy.
5. Solução De Problemas
Esta seção fornece soluções para problemas comuns que você pode encontrar:
| Problema | Possível causa | Solução |
|---|---|---|
| Sem energia | Power cable not connected, power outlet faulty, power switch off. | Check power cable connection, try a different outlet, ensure power switch is on. |
| Nenhuma forma de onda exibida | Input signal absent, probe not connected, channel off, incorrect vertical/horizontal settings. | Verify signal source, check probe connection, activate channel, use AUTO button or manually adjust V/div and s/div. |
| forma de onda instável | Incorrect trigger settings, noisy signal. | Adjust trigger level and mode. Consider using the 20MHz bandwidth limit to reduce noise. |
| Medições incorretas | Improper probe attenuation setting, uncalibrated device. | Ensure probe attenuation (e.g., 1X, 10X) matches the oscilloscope setting. Consider professional calibration. |
