Operating Instructions

This section outlines the basic steps for operating the oscilloscope to capture and analyze waveforms.

Basic Waveform Capture

1. Connect Probe: Attach a compensated probe to one of the analog input channels (e.g., Input 1).
2. Connect to Circuit: Connect the probe tip to the test point in your circuit and the ground clip to the circuit's ground.
3. Auto-Set: Press the Auto-Set button (if available, common on oscilloscopes) to automatically adjust vertical and horizontal settings for a stable display.
4. Adjust Vertical Scale: Use the Vertical Scale knob to adjust the volts per division, controlling the amplitude of the waveform on the screen.
5. Adjust Horizontal Scale: Use the Horizontal Scale knob to adjust the seconds per division, controlling the time base of the waveform.
6. Adjust Trigger: Use the Trigger Level knob to set the voltage level at which the oscilloscope captures the waveform, ensuring a stable display.

Measurement Functions

Maintenance

Proper maintenance ensures the longevity and accuracy of your oscilloscope.

Cleaning

• Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Ensure no liquid enters the instrument.
• Clean the display screen with a soft, lint-free cloth specifically designed for electronic displays.

Calibration

For optimal performance, periodic calibration by qualified service personnel is recommended. Refer to the official Tektronix service manual for calibration procedures and intervals.

Troubleshooting

This section provides solutions to common issues you might encounter.

• No Display:
  • Ensure the power cord is securely connected and the instrument is powered on.
  • Check the brightness and contrast settings of the display.
• Unstable Waveform:
  • Adjust the trigger level and trigger source settings.
  • Verify the probe compensation is correct.
  • Check for proper grounding of the probe and the circuit under test.
• No Signal Detected:
  • Ensure the probe is correctly connected to the input channel and the circuit.
  • Check the input coupling (AC/DC/GND) and vertical scale settings.
  • Verify the signal source is active.
