Setup

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

1. Unpacking: 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. Power Connection: Connect the power cord to the instrument and then to a grounded AC power outlet matching the specified voltage.
4. Probe Connection: Connect the desired probes to the input channels. Ensure probes are properly compensated before use.
5. Initial Power On: Turn on the oscilloscope and allow it to warm up for a few minutes as per the specific instructions in the full manual.

Operating Instructions

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

• Power On/Off: Use the main power switch to turn the unit on or off.
• Vertical Controls: Adjust the VOLTS/DIV knob for each channel to set the vertical sensitivity. Use the POSITION knob to move the waveform vertically.
• Horizontal Controls: Adjust the SEC/DIV knob to set the time base. Use the POSITION knob to move the waveform horizontally.
• Triggering: Set the TRIGGER LEVEL and SOURCE to stabilize the waveform display. The T912, being a storage oscilloscope, allows for capturing single-shot events.
• Storage Function: 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.

Maintenance

Regular maintenance ensures the longevity and performance of your oscilloscope:

• Cleaning: Disconnect power before cleaning. Use a soft, damp cloth with a mild detergent to clean the exterior. Avoid abrasive cleaners or solvents.
• Storage: When not in use, store the oscilloscope in a clean, dry environment, protected from dust and extreme temperatures.
• Calibration: 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.
• Probe Care: Inspect probes regularly for damage. Keep probe tips clean.

Troubleshooting

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

• No Display:
  • Check power connection and fuse.
  • Ensure intensity and focus controls are not set to minimum.
  • Verify that the oscilloscope is powered on.
• Unstable Waveform:
  • Adjust the trigger level and source settings.
  • Check probe connections and compensation.
  • Ensure the input signal is within the oscilloscope's measurement range.
• No Signal Displayed:
  • 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.
• Distorted Waveform:
  • Check probe compensation.
  • Ensure the signal amplitude does not exceed the vertical range.
  • Verify the signal frequency is within the oscilloscope's bandwidth.
