Installation

Proper setup is crucial for accurate measurements and safe operation. Follow these general steps:

1. Déballage: Carefully remove the oscilloscope and all accessories from its packaging. Inspect for any signs of shipping damage.
2. Placement: Place the oscilloscope on a stable, level surface with adequate ventilation space around it.
3. Connexion électrique : Connect the power cord to the instrument and then to a grounded AC power outlet matching the specified voltage.
4. Connexion de la sonde : Connect the desired probes to the input channels. Ensure probes are properly compensated before use.
5. Mise sous tension initiale : Turn on the oscilloscope and allow it to warm up for a few minutes as per the specific instructions in the full manual.

Mode d'emploi

The Tektronix T912 is a 10 MHz storage oscilloscope designed for capturing and displaying waveforms. Basic operation involves:

• Marche/Arrêt : Utilisez l'interrupteur principal pour allumer ou éteindre l'appareil.
• Commandes verticales : Adjust the VOLTS/DIV knob for each channel to set the vertical sensitivity. Use the POSITION knob to move the waveform vertically.
• Commandes horizontales : Adjust the SEC/DIV knob to set the time base. Use the POSITION knob to move the waveform horizontally.
• Déclenchement : Set the TRIGGER LEVEL and SOURCE to stabilize the waveform display. The T912, being a storage oscilloscope, allows for capturing single-shot events.
• Fonction de stockage : Utilize the storage controls to capture and hold transient or non-repetitive waveforms on the screen for detailed analysis. Refer to the full manual for specific storage mode operations.
• Focus and Intensity: Adjust these controls for a clear and bright display.

Entretien

Regular maintenance ensures the longevity and performance of your oscilloscope:

• Nettoyage: Débranchez l'alimentation avant le nettoyage. Utilisez un chiffon doux et sec.amp cloth with a mild detergent to clean the exterior. Avoid abrasive cleaners or solvents.
• Stockage: When not in use, store the oscilloscope in a clean, dry environment, protected from dust and extreme temperatures.
• Étalonnage: Periodically, the oscilloscope may require calibration to maintain accuracy. Refer to the detailed calibration procedures in the complete service manual or contact qualified service personnel.
• Entretien de la sonde : Inspect probes regularly for damage. Keep probe tips clean.

Dépannage

If you encounter issues with your Tektronix T912, consider the following common troubleshooting steps:

• Pas d'affichage :
  • Vérifiez la connexion électrique et le fusible.
  • Ensure intensity and focus controls are not set to minimum.
  • Verify that the oscilloscope is powered on.
• Forme d'onde instable :
  • Adjust the trigger level and source settings.
  • Check probe connections and compensation.
  • Assurez-vous que le signal d'entrée se situe dans la plage de mesure de l'oscilloscope.
• Aucun signal affiché :
  • Verify the input signal is present at the probe tip.
  • Check channel selection and vertical position.
  • Ensure the probe is correctly connected to the circuit under test.
• Forme d'onde déformée :
  • Check probe compensation.
  • Assurez-vous que le signal amplitude does not exceed the vertical range.
  • Verify the signal frequency is within the oscilloscope's bandwidth.
