  • Uistite sa, že prístroj je správne uzemnený, aby ste predišli úrazu elektrickým prúdom.
  • Do not operate the instrument in wet or damp podmienky.
  • Vyhnite sa prevádzke vo výbušnom prostredí.
  • Do not remove the instrument cover. Refer servicing to qualified personnel.
  • Use appropriate probes and accessories.
  • Pred čistením odpojte napájanie.

3. Obsah balenia

Overte si, či sú vo vašom balení všetky nižšie uvedené položky:

  • Rigol DHO1074 Digital Oscilloscope (1 unit)
  • Napájací kábel (1 kus)
  • Passive Probes (4 units, one for each channel)
  • USB kábel (1 kus)
  • Stručný návod (1 jednotka)
  • Resource CD (1 unit)

4. Nastavenie

4.1 Pripojenie napájania

  1. Uistite sa, že je hlavný vypínač osciloskopu v polohe VYPNUTÉ.
  2. Pripojte dodaný napájací kábel k vstupu striedavého prúdu na zadnom paneli osciloskopu.
  3. Zapojte druhý koniec napájacieho kábla do uzemnenej sieťovej zásuvky.

4.2 Pripojenie sond

  1. Connect the BNC connector of a passive probe to one of the input channels (CH1, CH2, CH3, or CH4) on the front panel.
  2. Attach the probe ground clip to a common ground point in your circuit.
  3. Pripojte hrot sondy k testovanému bodu vo vašom obvode.
  4. For accurate measurements, compensate the probe before use. Refer to the "Probe Compensation" section in the full user manual for detailed instructions.

4.3 Prvé zapnutie

  1. Press the power switch on the front panel to turn on the oscilloscope.
  2. The instrument will perform a self-test and display the startup screen.
  3. Once the main interface appears, the oscilloscope is ready for use.

5. Obsluha osciloskopu

The Rigol DHO1074 offers a user-friendly interface for capturing and analyzing waveforms. Key features include 4 analog channels, 70 MHz bandwidth, and a 12-bit vertical resolution for enhanced signal fidelity.

5.1 Základné snímanie priebehu

  1. Zapnutie: Ensure the oscilloscope is powered on as described in Section 4.3.
  2. Pripojte signál: Connect your signal source to an input channel using a compensated probe.
  3. Automatické nastavenie: Stlačte tlačidlo AUTOMATICKY button on the front panel. The oscilloscope will automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
  4. Manuálne úpravy:
    • Použite vertikálne knobs (VOLTS/DIV) to adjust the vertical scale (voltage per division) for each channel.
    • Použite HORIZONTÁLNY knob (SEC/DIV) to adjust the horizontal scale (time per division).
    • Použite SPÚŠŤAČ controls to set the trigger level and mode for stable waveform capture.

5.2 Pokročilé funkcie

  • Vysoké rozlíšenie: Benefit from the 12-bit vertical resolution, providing 16 times more quantization levels than standard 8-bit oscilloscopes, which improves measurement accuracy and reduces quantization noise.
  • Deep Memory: The DHO1074 features a 50 Mpts maximum memory depth (expandable to 100 Mpts with option DHO1000-RLU-01), allowing for longer waveform captures at high sample sadzby.
  • Serial Decoding: Standard serial decoding capabilities include SPI, I2C, RS232/UART, CAN, and LIN, simplifying the analysis of common serial bus communications.
  • Funkcie merania: Access various automatic measurement functions (e.g., Vpp, Vrms, Frequency, Period) via the MEASURE menu.
  • Matematické funkcie: Utilize built-in math functions (e.g., Add, Subtract, Multiply, Divide, FFT) to perform waveform analysis.

6. Údržba

6.1 Čistenie prístroja

  • Pred čistením vždy odpojte napájací kábel.
  • Použite mäkkú handričku dampened with a mild detergent solution to clean the exterior surfaces.
  • Do not use abrasive cleaners or solvents that could damage the plastic parts.
  • Zabráňte striekaniu tekutín priamo na prístroj.

6.2 Skladovanie

  • Osciloskop skladujte v čistom a suchom prostredí, mimo dosahu priameho slnečného žiarenia a extrémnych teplôt.
  • Protect the screen from scratches.

6.3 Kalibrácia

For optimal performance and measurement accuracy, periodic calibration by qualified service personnel is recommended. Refer to Rigol's official support channels for calibration services.
