5. Utilisation de l'oscilloscope

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 Acquisition de formes d'onde de base

1. Mise sous tension : Ensure the oscilloscope is powered on as described in Section 4.3.
2. Signal de connexion : Connect your signal source to an input channel using a compensated probe.
3. Configuration automatique : Appuyez sur le AUTO button on the front panel. The oscilloscope will automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
4. Réglages manuels :
   • Utilisez le VERTICAL knobs (VOLTS/DIV) to adjust the vertical scale (voltage per division) for each channel.
   • Utilisez le HORIZONTAL knob (SEC/DIV) to adjust the horizontal scale (time per division).
   • Utilisez le DÉCLENCHEMENT controls to set the trigger level and mode for stable waveform capture.

5.2 fonctionnalités avancées

• Haute résolution: 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 samples tarifs.
• Serial Decoding: Standard serial decoding capabilities include SPI, I2C, RS232/UART, CAN, and LIN, simplifying the analysis of common serial bus communications.
• Fonctions de mesure : Access various automatic measurement functions (e.g., Vpp, Vrms, Frequency, Period) via the MESURE menu.
• Fonctions mathématiques : Utilize built-in math functions (e.g., Add, Subtract, Multiply, Divide, FFT) to perform waveform analysis.

6. Entretien

6.1 Nettoyage de l'appareil

• Débranchez toujours le cordon d'alimentation avant de nettoyer.
• Utilisez un chiffon doux dampened with a mild detergent solution to clean the exterior surfaces.
• Do not use abrasive cleaners or solvents that could damage the plastic parts.
• Évitez de vaporiser des liquides directement sur l'instrument.

6.2 Stockage
