5. Instruccions de funcionament

This section outlines the basic steps for operating your VOLTCRAFT DSO-2020 USB oscilloscope.

5.1 Inici del programari

After successful installation and connection, launch the VOLTCRAFT oscilloscope application from your computer's desktop or start menu. The software interface will display a virtual oscilloscope screen, similar to a traditional benchtop unit.

5.2 Basic Signal Acquisition

1. Connect Signal: Attach the probe to the circuit point you wish to measure.
2. Selecció de canals: In the software, enable the desired channel (CH1 or CH2).
3. Escala vertical (Volts/Div): Adjust the vertical scale to fit the signal amplitude on the screen.
4. Horizontal Scale (Time/Div): Adjust the horizontal scale to view the signal's period or frequency.
5. Configuració de l'activador: Configure the trigger source, type (edge, pulse), and level to stabilize the waveform. The software provides controls similar to a physical oscilloscope.
6. Configuració automàtica: Utilize the automatic setup function within the software. This feature automatically adjusts the vertical and horizontal settings to display the input signal optimally.

5.3 Data Processing and Export

The DSO-2020 USB allows for advanced data processing and storage:

• Waveform Storage: Captured waveforms can be saved directly to your computer for later analysis.
• Funcions de mesura: The software includes various automatic measurement functions (e.g., Vpp, Vrms, Frequency, Period).
• Exportació de dades: Measurement data can be exported to formats such as Excel for further analysis and reporting.
• LaboratoriVIEW Compatibilitat: The device is compatible with LabVIEW, allowing for integration into custom measurement and automation systems.

6. Manteniment

Un manteniment adequat garanteix la longevitat i la precisió del vostre oscil·loscopi.

• Neteja: Feu servir un drap suau i sec per netejar l'exterior del dispositiu. No utilitzeu productes de neteja abrasius ni dissolvents.
• Emmagatzematge: Store the oscilloscope in a dry, dust-free environment when not in use. Avoid extreme temperatures.
• Cura de la sonda: Handle probes carefully. Avoid bending or stressing the cables. Store them properly to prevent damage.
