2. Configuração e Configuração Inicial
2.1 Desembalagem e Inspeção
Carefully remove the oscilloscope from its packaging. Inspect the unit for any signs of physical damage that may have occurred during transit. Retain the original packaging for future transportation or storage.
2.2 Conexão de Energia
- Certifique-se de que a chave de alimentação do osciloscópio esteja na posição DESLIGADO.
- Connect the provided power cord to the AC input on the rear panel of the oscilloscope.
- Conecte a outra extremidade do cabo de alimentação a uma tomada elétrica CA aterrada.
2.3 Inicialização Inicial
Press the power button located on the front panel. The oscilloscope will perform a self-test and boot up. The display will show the Tektronix logo followed by the main measurement interface.
2.4 Connecting Probes and Inputs
The MSO44 features FlexChannels, which can be configured as analog or digital inputs.
- For analog signals, connect BNC probes to the input connectors on the front panel.
- For digital signals, use the appropriate digital probe accessories (sold separately) and connect them to the dedicated digital input ports.
- Ensure all connections are secure to prevent signal degradation.
3. Instruções de operação
3.1 interface do usuário sobreview
The oscilloscope features a 13.3-inch HD capacitive touchscreen display for intuitive operation. Key controls are also available via physical knobs and buttons on the right side of the display.
3.2 Medidas Básicas
- Configuração do canal: Press the channel button corresponding to the input you wish to configure. Use the touchscreen or vertical scale knob to adjust vertical sensitivity (Volts/Div).
- Base de tempo: Use the horizontal scale knob to adjust the time base (Seconds/Div) to view o número desejado de ciclos.
- Acionamento: The trigger system stabilizes repetitive waveforms. Use the trigger level knob to set the trigger threshold. Select trigger type (Edge, Pulse, Runt, etc.) from the trigger menu on the screen.
- Medidas: Access the 'Measure' menu to add automatic measurements such as frequency, peak-to-peak voltage, RMS, etc.
3.3 Recursos avançados
- FlexChannel Technology: Each FlexChannel input can be configured as one analog channel or eight digital logic channels. This is configured through the channel setup menu.
- High Resolution Mode: The oscilloscope offers 12-bit ADC resolution, which can be enhanced to 16 bits in High Resolution Mode for more precise measurements. Enable this mode via the display settings.
- Duração do registro: The MSO44 features a 31.25 M record length, allowing for capture of long signal durations at high sample rates. Adjust record length settings in the acquisition menu.
- Ferramentas de análise: Utilize built-in analysis tools such as FFT (Fast Fourier Transform) for frequency domain analysis, cursors for precise point measurements, and waveform math functions.
4. Manutenção
4.1 Limpando o Instrumento
To maintain the performance and appearance of your oscilloscope:
- Exterior: Use um pano macio e macioamp Use um pano com detergente neutro para limpar as superfícies externas. Evite produtos de limpeza abrasivos ou solventes.
- Mostrar: Use a soft, lint-free cloth specifically designed for cleaning electronic displays. Do not spray cleaning solutions directly onto the screen.
- Conectores: Keep input connectors clean and free of dust. Use compressed air if necessary, but avoid inserting objects into the connectors.
4.2 Calibração
The MSO44 is factory calibrated. For optimal performance, periodic calibration by a qualified service center is recommended. Refer to the Tektronix website or contact support for calibration services.
4.3 Armazenamento
When not in use for extended periods, store the oscilloscope in a clean, dry environment, away from direct sunlight and extreme temperatures. Use the original packaging or a suitable protective case.
