- Input Channels (CH1, CH2): BNC connectors for probe connection.
- Kontrolna dugmad: Dedicated knobs for Multipurpose, Position, Horizontal, Vertical, and Trigger adjustments.
- Funkcijska dugmad: Buttons for Utility, Measure, Acquire, Cursor, Display, Storage, etc.
- USB Host Interface: Located on the front panel for data storage.
2.3. Povezivanje napajanja
Connect the provided power cord to the AC input on the rear panel of the oscilloscope and then to a suitable power outlet.
2.4. Spajanje sondi
Connect the oscilloscope probes to the CH1 and CH2 BNC input connectors on the front panel. Ensure a secure connection. The probes are used to connect the oscilloscope to the circuit under test.
3. Uputstvo za upotrebu
3.1. Uključivanje/isključivanje
Pritisnite dugme za napajanje na prednjoj ploči da biste uključili ili isključili osciloskop.
3.2. Osnovni prikaz talasnog oblika
After powering on, connect a signal to CH1 or CH2. Use the Vertical (Position and Scale) and Horizontal (Position and Scale) knobs to adjust the waveform's position and size on the screen. The oscilloscope features a 110MHz bandwidth and 1GSa/s real-time sampling rate for accurate signal capture.
3.3. Triggering
The Trigger section allows you to stabilize repetitive waveforms. Adjust the Trigger Level knob to set the voltage threshold at which the oscilloscope starts acquiring data. Use the Trigger Menu button to access advanced trigger settings.
3.4. Mjerenja
Press the 'Measure' button to access automatic measurement functions. The oscilloscope can display various parameters such as frequency, peak-to-peak voltage, RMS voltage, i više.
3.5. Pohranjivanje podataka
The USB Host interface on the front panel allows you to save waveform data, screenshots, and settings to a USB flash drive. The storage depth for acquired waveforms is not less than 10K sampling pointa.
4. Održavanje
4.1. Čišćenje
To clean the oscilloscope, use a soft, dry cloth. For stubborn dirt, a cloth lightly dampened with water or a mild cleaning solution can be used. Avoid using abrasive cleaners or solvents that could damage the casing ili ekran. Prije čišćenja provjerite je li uređaj isključen i iskopčan iz struje.
4.2. Skladištenje
Store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and high humidity. When not in use for extended periods, disconnect all probes and power cables.
5. Otkrivanje problema
- Nema napajanja: Ensure the power cord is securely connected to both the oscilloscope and the power outlet. Check the power button.
- Nema prikaza talasnog oblika: Verify that the input signal is connected correctly to CH1 or CH2. Adjust the Vertical Scale (V/div) and Horizontal Scale (s/div) knobs to bring the waveform into view. Check the trigger settings.
- Nestabilan talasni oblik: Adjust the Trigger Level and Trigger Mode settings to stabilize the waveform. Ensure the trigger source is correctly selected.
- Netačna mjerenja: Calibrate probes if necessary. Ensure the input coupling (AC/DC) is appropriate for the signal being measured.
- Kvar uređaja: If the oscilloscope does not function correctly upon receipt, contact customer support for immediate assistance. The manufacturer offers replacement for new items at once for such issues.
