5. Persediaan
Follow these steps for initial setup of your oscilloscope:
- Membongkar: Carefully remove the oscilloscope and all accessories from the packaging. Inspect for any signs of damage.
- Sambungan Kuasa: Connect the USB Type-C power supply to the oscilloscope's power input and then plug it into a suitable power outlet.
- Hidupkan kuasa: Press the power button located on the front panel to turn on the device. The display will illuminate.
- Sambungan Probe: Connect the test probes to the desired analog input channels (CH1-CH4) on the front panel. Ensure a secure connection.
- Pampasan Probe: It is recommended to perform probe compensation before making critical measurements. Connect a probe to the probe compensation output (usually a square wave signal) and adjust the probe's compensation trimmer until the waveform is a perfect square.
- Logic Analyzer Connection (Optional): If using the logic analyzer, connect the logic analyzer probes to the dedicated input port.
6. Arahan Operasi
6.1 Operasi Asas
- Navigasi skrin sentuh: The 7-inch touchscreen allows intuitive control. Tap icons and menus to select functions. Gesture control simplifies common operations.
- Kawalan Menegak: Use the vertical position and scale knobs for each channel (CH1-CH4) to adjust the vertical position and voltage per division of the waveform.
- Kawalan Mendatar: Use the horizontal position and scale knobs to adjust the time base (time per division) and horizontal position of the waveform.
- Lari/Berhenti: Tekan ke Lari / Berhenti button to start or pause waveform acquisition.
- Tetapkan Automatik: Tekan ke Autoset button for automatic setup of vertical, horizontal, and trigger settings to display a stable waveform.
6.2 Advanced Triggering
The DOV2504 LA offers a wide array of trigger functions to capture specific events:
- Accessing Trigger Menu: Tap the "Trigger" icon on the screen or use the dedicated trigger button to access trigger settings.
- Trigger Types: Select from Edge, Video, Pulse, Slope, Runt, Window, Timeout, Nth, Logic, RS232/UART, I2C, SPI, CAN, and LIN triggers. Each type has specific parameters to configure.
- Sumber Pencetus: The trigger source can be any of the four analog channels (CH1-CH4) or the 16-channel logic analyzer (LA).
- Tahap Pencetus: Adjust the trigger level to define the voltage threshold at which the oscilloscope captures a waveform.
6.3 Logic Analyzer Functionality
The integrated 16-channel logic analyzer allows for digital signal analysis:
- Connecting Digital Signals: Connect your digital signals to the dedicated logic analyzer input port using the appropriate probes.
- Activating LA: Select the Logic Analyzer (LA) mode from the input channel selection or a dedicated LA menu.
- Digital Waveform Display: The oscilloscope will display the digital waveforms, allowing for timing analysis and protocol decoding (if supported by the software).
7. Penyelenggaraan
Proper maintenance ensures the longevity and accuracy of your oscilloscope:
- Pembersihan: Regularly clean the exterior of the oscilloscope with a soft, dry, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water. Do not use abrasive cleaners, solvents, or alcohol.
- Penjagaan Skrin: Use a screen-specific cleaner and a microfiber cloth for the touchscreen. Avoid pressing hard or using sharp objects on the screen.
- Storan: When not in use, store the oscilloscope in a cool, dry place, away from direct sunlight and extreme temperatures. Protect it from dust and vibrations.
- Penjagaan Probe: Handle probes carefully. Avoid bending or kinking the cables. Store them neatly to prevent damage.
