4. Configuració

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

1. Desembalatge: Carefully remove the oscilloscope and all accessories from the packaging. Verify that all components are present and undamaged.
2. Connexió d'alimentació: 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. Connexió de la sonda: Connect the oscilloscope probes to the desired BNC input channels (CH1, CH2, CH3, CH4) on the front panel. Ensure a secure connection.
4. Compensació de la 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. Encès: 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. Instruccions de funcionament

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

5.1 Mesures bàsiques

• Ample de banda: The device operates at a 100 MHz bandwidth across 4 channels.
• SampTarifa de ling: El màxim sampling rate is 1 GSa/s, allowing for detailed capture of fast signals.
• Resolució vertical: With an 8-bit vertical resolution, the oscilloscope provides good precision for voltage mesures.
• Visualització: 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.
• Posició vertical: Use the position knobs to move the waveform vertically on the screen.
• Horizontal Scale (Time/Div): Use the horizontal control knob to adjust the time base, changing the horizontal compression or expansion of the waveform.
• Posició horitzontal: Use the horizontal position knob to shift the waveform left or right.

5.3 Activació

Triggering stabilizes repetitive waveforms and captures single-shot events.

• Nivell d'activació: Adjust the trigger level knob to set the voltage point at which the oscilloscope will trigger.
• Mode de commutació: 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 Emmagatzematge i recuperació de dades

• Interfície 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. Manteniment

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

• Neteja:
  • Desconnecteu sempre el cable d'alimentació abans de netejar.
  • Utilitzeu un suau, damp cloth with a mild detergent to clean the exterior of the device.
  • Do not use abrasive cleaners or solvents, as they may damage the casing o pantalla.
  • Keep the display screen clean using a soft, lint-free cloth.
• Emmagatzematge:
  • Store the oscilloscope in a dry, dust-free environment away from direct sunlight and extreme temperatures.
  • When not in use, cover the device to protect it from dust accumulation.

7. Solució De Problemes

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

7.1 Sense poder

• Comproveu el cable d'alimentació: Ensure the power cable is securely connected to both the oscilloscope and the power outlet.
• Comproveu la presa de corrent: Verifiqueu que la presa de corrent funciona connectant-hi un altre dispositiu.
• Comproveu el fusible: If applicable, check the power fuse (refer to the device label for fuse specifications and replacement instructions, if user-replaceable).

7.2 No Waveform Displayed

• Comproveu la connexió de la 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.
• Ajusta l'escala vertical: The waveform might be off-screen. Adjust the Volts/Div knob to a suitable range.
• Ajusta l'escala horitzontal: 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.
• Run/Stop Button: Ensure the oscilloscope is in "Run" mode (not paused).

7.3 Unstable Waveform

• 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.
