3. Installatiehandleiding
3.1 Software-installatie
- Insert the provided software CD into your computer's CD-ROM drive.
- Locate and run the setup executable file. Follow the on-screen instructions to install the OWON oscilloscope software and necessary drivers.
- Alternatively, download the latest software and drivers from the official OWON website. Ensure you select the correct model (VDS1022I) and operating system.
- During installation, ensure that the oscilloscope is NOT connected to the PC until prompted, or until the software installation is complete. This helps ensure proper driver recognition.
3.2 Connecting the Oscilloscope
- Connect one end of the supplied USB cable to the USB port on the OWON VDS1022I unit.
- Connect the other end of the USB cable to an available USB port on your PC. The device is bus-powered, so no external power adapter is required.
- Your operating system should detect the device and, if drivers were installed correctly, recognize it as an OWON VDS1022I oscilloscope.
3.3 Sondeaansluiting en compensatie
- Connect the oscilloscope probes to the CH1 and CH2 input BNC connectors on the device.
- Bevestig de aardingsklem van de meetsonde aan een bekend aardingspunt in uw circuit.
- To compensate the probe, connect the probe tip to the 5V 1KHz Probe Compensation output.
- Adjust the compensation screw on the probe body until a flat-top square wave is displayed on the software interface. This ensures accurate signal representation.
4. Gebruiksaanwijzing
4.1 De software opstarten
After successful installation and connection, launch the OWON oscilloscope application from your desktop shortcut or Start Menu. The software interface will display the waveform acquisition window.
4.2 Basisweergave van golfvormen
- Verticale schaal (Volt/Div): Adjust the vertical sensitivity for each channel using the controls in the software. This determines the voltage represented by each vertical division on the display.
- Horizontal Scale (Time/Div): Adjust the horizontal time base to control the time represented by each horizontal division. This affects the displayed duration of the waveform.
- Ingangskoppeling: Select DC, AC, or GND coupling for each channel as needed.
- DC: Displays both AC and DC components of the signal.
- Wisselstroom: Blocks the DC component, displaying only the AC component.
- GND: Disconnects the input signal, displaying a ground reference line.
4.3 Activeren
Triggering stabilizes repetitive waveforms and captures single-shot events. The VDS1022I supports various trigger modes:
- Randtrigger: Triggers on a rising or falling edge of the input signal at a specified voltage niveau.
- Video Trigger: Triggers on standard video signals.
- Slope Trigger: Triggers on a signal's rise or fall time.
- Pulstrigger: Triggers on pulses of specific width.
- Alternate Trigger: Allows triggering on two different channels alternately.
Adjust the trigger level and mode within the software to achieve a stable waveform display.
4.4 Measurements and Analysis
- Automatische metingen: The software provides automatic measurements for parameters like Vpp, Vmax, Vmin, Freq, Period, RMS, etc. Select desired measurements from the menu.
- Cursors: Gebruik voltage and time cursors to manually measure specific points on the waveform.
- FFT (Fast Fourier Transform): Access the FFT function to analyze the frequency components of your signal.
- XY-modus: Display the relationship between two signals in X-Y format, useful for phase comparisons or Lissajous figures.
5. Onderhoud
- Schoonmaak: Gebruik een zachte, droge doek om de buitenkant van de oscilloscoop schoon te maken. Voor hardnekkig vuil kunt u een iets drogere doek gebruiken.amp Een doekje met een mild reinigingsmiddel kan worden gebruikt, zolang er maar geen vloeistof in het apparaat terechtkomt.
- Opslag: Bewaar het apparaat op een koele, droge plaats, uit de buurt van direct zonlicht en extreme temperaturen.
- Sondeonderhoud: Handle probes carefully. Avoid bending or stressing the cables excessively. Keep probe tips clean.
- Software-updates: Periodically check the OWON webDeze website biedt software- en firmware-updates aan om optimale prestaties en toegang tot nieuwe functies te garanderen.
6. Probleemoplossing
6.1 Device Not Recognized by PC
- Ensure the USB cable is securely connected to both the oscilloscope and the PC.
- Verify that the correct drivers have been installed. Reinstall drivers if necessary, following the instructions in Section 3.1.
- Probeer een andere USB-poort op je pc aan te sluiten.
- Start uw computer opnieuw op en probeer het nogmaals.
6.2 No Waveform Display or Unstable Waveform
- Check probe connections to the device and the circuit under test. Ensure ground clips are properly connected.
- Verify that the input coupling (DC/AC/GND) is set appropriately for your signal.
- Adjust the vertical (Volts/Div) and horizontal (Time/Div) scales to match the expected signal characteristics.
- Pas het triggerniveau en de triggermodus aan. Een instabiele golfvorm duidt vaak op een onjuiste triggerinstelling.
- Ensure the signal source is active and producing a signal within the oscilloscope's measurement range.
6.3 Software Issues or Crashes
- Ensure your operating system meets the minimum requirements for the OWON software.
- Update the software to the latest version from the OWON webplaats.
- Sluit andere veeleisende applicaties die mogelijk systeembronnen verbruiken.
- If issues persist, try reinstalling the software.
6.4 Limited Bandwidth or Signal Distortion
- The VDS1022I has a 25MHz bandwidth. Signals exceeding this frequency may be attenuated or distorted.
- Ensure probes are correctly compensated (refer to Section 3.3).
- For high-frequency measurements, ensure proper grounding and minimize cable lengths to reduce noise.
