- 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 Muunganisho wa Uchunguzi na Fidia
- Connect the oscilloscope probes to the CH1 and CH2 input BNC connectors on the device.
- Attach the probe ground clip to a known ground point in your 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. Maagizo ya Uendeshaji
4.1 Kuzindua Programu
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 Onyesho la Msingi la Umbo la Wimbi
- Kipimo cha Wima (Volts/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.
- Kipimo cha Mlalo (Muda/Mgawanyiko): Adjust the horizontal time base to control the time represented by each horizontal division. This affects the displayed duration of the waveform.
- Uunganishaji wa Ingizo: Select DC, AC, or GND coupling for each channel as needed.
- DC: Displays both AC and DC components of the signal.
- AC: Blocks the DC component, displaying only the AC component.
- GND: Disconnects the input signal, displaying a ground reference line.
4.3 Kuchochea
Triggering stabilizes repetitive waveforms and captures single-shot events. The VDS1022I supports various trigger modes:
- Kichocheo cha Ukingo: Triggers on a rising or falling edge of the input signal at a specified voltagkiwango.
- Kichocheo cha Video: Vichochezi kwenye mawimbi ya kawaida ya video.
- Kichocheo cha Mteremko: Triggers on a signal's rise or fall time.
- Pulse Trigger: 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 Vipimo na Uchambuzi
- Vipimo vya Kiotomatiki: The software provides automatic measurements for parameters like Vpp, Vmax, Vmin, Freq, Period, RMS, etc. Select desired measurements from the menu.
