5. Operating Instructions

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

5.1 Lanciamentu di u Software

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. Selezzione di canali: In the software, enable the desired channel (CH1 or CH2).
3. Vertical Scale (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. Impostazioni di trigger: Configure the trigger source, type (edge, pulse), and level to stabilize the waveform. The software provides controls similar to a physical oscilloscope.
6. Configurazione automatica: 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:

• Archiviazione di forme d'onda: Captured waveforms can be saved directly to your computer for later analysis.
• Funzioni di misurazione: The software includes various automatic measurement functions (e.g., Vpp, Vrms, Frequency, Period).
• Esportazione di dati: Measurement data can be exported to formats such as Excel for further analysis and reporting.
• LabVIEW Cumpatibilità: The device is compatible with LabVIEW, allowing for integration into custom measurement and automation systems.

6. Mantenimentu

Una manutenzione adatta garantisce a longevità è a precisione di u vostru oscilloscopiu.

• Pulizia: Aduprate un pannu dolce è asciuttu per pulisce l'esternu di u dispusitivu. Ùn aduprate micca detergenti abrasivi o solventi.
• Conservazione: Store the oscilloscope in a dry, dust-free environment when not in use. Avoid extreme temperatures.
• Cura di a sonda: Handle probes carefully. Avoid bending or stressing the cables. Store them properly to prevent damage.
• Actualizazioni di u software: Regularly check the VOLTCRAFT website for software and driver updates to ensure optimal performance and compatibility.

7. Risoluzione di prublemi

Questa sezione tratta di prublemi cumuni chì pudete scuntrà.

• Dispositivu micca ricunnisciutu:
  • Ensure the USB cable is securely connected to both the oscilloscope and the PC.
  • Verificate chì i driver sò stallati currettamente. Reinstallateli se necessariu.
  • Pruvate un portu USB differente in u vostru urdinatore.
• Nisun signalu affissatu:
  • Check that the probe is properly connected to the input channel and the circuit under test.
  • Ensure the correct channel is enabled in the software.
  • Adjust the vertical (Volts/Div) and horizontal (Time/Div) scales.
  • Check trigger settings; an incorrect trigger level can prevent a stable display.
