5. Arahan Operasi

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

5.1 Melancarkan Perisian

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. Sambungkan Isyarat: Attach the probe to the circuit point you wish to measure.
2. Pemilihan Saluran: In the software, enable the desired channel (CH1 or CH2).
3. Skala Menegak (Volt/Div): Adjust the vertical scale to fit the signal amplitude on the screen.
4. Skala Mendatar (Masa/Div): Adjust the horizontal scale to view the signal's period or frequency.
5. Tetapan Pencetus: Configure the trigger source, type (edge, pulse), and level to stabilize the waveform. The software provides controls similar to a physical oscilloscope.
6. Persediaan Auto: 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:

• Penyimpanan Bentuk Gelombang: Captured waveforms can be saved directly to your computer for later analysis.
• Fungsi Pengukuran: The software includes various automatic measurement functions (e.g., Vpp, Vrms, Frequency, Period).
• Eksport Data: Measurement data can be exported to formats such as Excel for further analysis and reporting.
• MakmalVIEW Keserasian: The device is compatible with LabVIEW, allowing for integration into custom measurement and automation systems.

6. Penyelenggaraan

Penyelenggaraan yang betul memastikan jangka hayat dan ketepatan osiloskop anda.

• Pembersihan: Gunakan kain lembut dan kering untuk membersihkan bahagian luar peranti. Jangan gunakan pembersih atau pelarut yang kasar.
• Storan: Store the oscilloscope in a dry, dust-free environment when not in use. Avoid extreme temperatures.
• Penjagaan Probe: Kendalikan prob dengan berhati-hati. Elakkan membengkokkan atau menekan kabel. Simpannya dengan betul untuk mengelakkan kerosakan.
• Kemas Kini Perisian: Regularly check the VOLTCRAFT website for software and driver updates to ensure optimal performance and compatibility.

7. Penyelesaian masalah

Bahagian ini menangani isu biasa yang mungkin anda hadapi.

• Peranti Tidak Dikenali:
  • Pastikan kabel USB disambungkan dengan kukuh ke kedua-dua osiloskop dan PC.
  • Sahkan bahawa pemacu telah dipasang dengan betul. Pasang semula jika perlu.
  • Cuba port USB lain pada komputer anda.
• Tiada Isyarat Dipaparkan:
  • 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.
  • Laraskan skala menegak (Volt/Div) dan mendatar (Masa/Div).
  • Check trigger settings; an incorrect trigger level can prevent a stable display.
  • Verify the signal source is active and within the oscilloscope's measurement range.
• Bentuk Gelombang Tidak Stabil:
  • Adjust the trigger level and trigger type (e.g., edge trigger).
  • Ensure the trigger source is set to the channel with the signal.
  • Check for noise in the measurement environment.
