4.1 Maitinimo prijungimas

1. Įsitikinkite, kad osciloskopo maitinimo jungiklis yra IŠJUNGTOJE padėtyje.
2. Prijunkite pateiktą maitinimo laidą prie kintamosios srovės maitinimo įvesties, esančios osciloskopo galiniame skydelyje.
3. Kitą maitinimo laido galą prijunkite prie įžeminto kintamosios srovės lizdo.

4.2 Zondų prijungimas

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. Prijunkite zondo antgalį prie bandymo taško savo grandinėje.
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 Pradinis įjungimas

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. Osciloskopo valdymas

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 Basic Waveform Acquisition

1. Maitinimas: Ensure the oscilloscope is powered on as described in Section 4.3.
2. Prijungimo signalas: Connect your signal source to an input channel using a compensated probe.
3. Automatinė sąranka: Paspauskite AUTO button on the front panel. The oscilloscope will automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
4. Rankinis reguliavimas:
   • Naudokite VERTIKALUS knobs (VOLTS/DIV) to adjust the vertical scale (voltage per division) for each channel.
   • Naudokite HORIZONTALUS knob (SEC/DIV) to adjust the horizontal scale (time per division).
   • Naudokite TRIGGER controls to set the trigger level and mode for stable waveform capture.

5.2 Išplėstinės funkcijos

• Didelė raiška: 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 tarifus.
• Serial Decoding: Standard serial decoding capabilities include SPI, I2C, RS232/UART, CAN, and LIN, simplifying the analysis of common serial bus communications.
• Matavimo funkcijos: Access various automatic measurement functions (e.g., Vpp, Vrms, Frequency, Period) via the PAMATUOKITE meniu.
• Matematinės funkcijos: Utilize built-in math functions (e.g., Add, Subtract, Multiply, Divide, FFT) to perform waveform analysis.

6. Priežiūra

6.1 Prietaiso valymas

• Prieš valydami visada atjunkite maitinimo laidą.
• Naudokite minkštą skudurėlį dampened with a mild detergent solution to clean the exterior surfaces.
• Do not use abrasive cleaners or solvents that could damage the plastic parts.
• Venkite purkšti skysčius tiesiai ant instrumento.

6.2 Saugykla

• Store the oscilloscope in a clean, dry environment, away from direct sunlight and extreme temperatures.
• Protect the screen from scratches.

6.3 Kalibravimas

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