4. Konec produktuview

The OWON XDS2102A features an intuitive front panel layout and a range of connectivity options.

4.1 Přední panel

The front panel includes an 8-inch 800x600 high-resolution LCD for waveform display, along with various control buttons and knobs for instrument operation.

This image displays the OWON XDS2102A digital oscilloscope from a front-right angle. The device features an 8-inch color LCD screen showing two waveforms: a yellow sine wave and a blue square wave. The front panel is equipped with numerous control knobs and buttons for various functions, including vertical and horizontal adjustments, triggering, and menu navigation. Input connectors for channels CH1, CH2, and EXT Trig are visible at the bottom right. A USB host port is located below the screen.

Mezi klíčové ovládací prvky patří:

• Víceúčelový knoflík: Pro navigaci v menu a nastavení parametrů.
• Funkční tlačítka: Such as Menu Off, Run/Stop, Single, Acquire, Autoset, Utility, Cursor, Save, Display, Help, Math.
• Vertikální ovládací prvky: Position and Scale knobs for CH1 and CH2.
• Horizontální ovládací prvky: Position and Scale knobs for time base adjustment.
• Vstupní konektory: BNC connectors for CH1, CH2, and EXT Trig.
• Hostitelský port USB: For data storage and firmware updates.
• Vypínač: Pro zapnutí nebo vypnutí zařízení.

4.2 Zadní panel

The rear panel provides additional connectivity:

• VGA port: For external display connection, useful for presentations or larger viewIng.
• LAN port: For network connectivity and remote control.
• AUX port: Auxiliary output.
• Port USB zařízení: Pro připojení k počítači.
• USB Port for PictBridge: For direct printing to compatible printers.

5. Nastavení

Follow these steps to set up your oscilloscope:

1. Připojení napájení: Connect the provided power cord to the oscilloscope's power input and then to a grounded AC power outlet.
2. Připojení sondy: Connect the oscilloscope probes to the CH1 and/or CH2 BNC input connectors. Ensure the probe's ground clip is securely connected to the circuit's ground.
3. Kompenzace sondy: For accurate measurements, compensate your probes. Connect the probe tip to the oscilloscope's probe compensation output (usually a square wave signal) and the ground clip to the ground terminal. Adjust the trimmer on the probe until the square wave displayed on the screen has flat tops and bottoms without overshoot or undershoot.
4. Zapnutí: Press the power button on the front panel to turn on the oscilloscope.

6. Návod k obsluze

This section covers basic operation of the OWON XDS2102A oscilloscope.

6.1 Základní měření

• Autoset: Stiskněte tlačítko Automatické nastavení button to automatically adjust the vertical, horizontal, and trigger settings for a stable display of most signals.
• Vertical Scale and Position: Použijte Měřítko knobs for CH1 and CH2 to adjust the vertical sensitivity (Volts/division). Use the Pozice knobs to move the waveform vertically on the screen.
• Horizontal Scale and Position: Use the horizontal Měřítko knob to adjust the time base (seconds/division). Use the horizontal Pozice knob to move the waveform horizontally.

6.2 Spouštění

Spouštění stabilizuje opakující se průběhy a zachycuje jednotlivé události.

• Režim spouštění: The XDS2102A supports various trigger modes. The default is typically Edge trigger.
• Zdroj spouštěče: Select the input channel (CH1, CH2, EXT Trig) or AC Line as the trigger source.
• Trigger Coupling: Options include DC, AC, Noise Reject, HF Reject, LF Reject.
• Trigger Slope: Choose between rising edge, falling edge, or both.
• Úroveň spouštění: Nastavením knoflíku úrovně spouště nastavte hlasitosttage threshold at which the trigger occurs.

6.3 Bus Decoding

The oscilloscope supports decoding for common serial bus protocols.

• Access the bus decoding function through the menu.
• Select the desired protocol (SPI, I2C, RS232, CAN).
• Configure the relevant parameters for the chosen bus, such as clock source, data source, and thresholds.

7. Údržba

Správná údržba zajišťuje dlouhou životnost a přesnost vašeho osciloskopu.

• Čištění: Use a soft, dry cloth to clean the exterior of the instrument. For stubborn dirt, use a cloth lightly dampened with water or a mild detergent. Do not use abrasive cleaners or solvents.
• Péče o sondu: Handle probes carefully. Avoid bending the probe cable sharply. Store probes in a clean, dry environment.
• Skladování: When not in use, store the oscilloscope in a cool, dry place, away from direct sunlight and extreme temperatures.

8. Řešení problémů

If you encounter issues with your OWON XDS2102A, refer to the following common troubleshooting tips:

• Bez napájení: Ensure the power cord is securely connected to both the oscilloscope and a working power outlet. Check the power switch position.
• Není zobrazen žádný signál: Verify that the input signal is connected correctly to the BNC input. Check probe connections and compensation. Adjust vertical scale and position. Ensure the trigger level is set appropriately. Try pressing the Automatické nastavení tlačítko.
• Zkreslený tvar vlny: Check probe compensation. Ensure the input signal amplitude does not exceed the oscilloscope's input range. Verify proper grounding.
• Nestabilní tvar vlny: Adjust trigger settings (source, level, slope, mode) to achieve a stable display.

Pokud problémy přetrvávají, požádejte o pomoc zákaznickou podporu.
