Tektronix TPP0500B Oscilloscope Probe User Manual

1. Introduktion

The Tektronix TPP0500B is a high-bandwidth, general-purpose passive voltage probe designed for precise signal acquisition. It is compatible with Tektronix MDO3000, MDO4000, MSO/DPO5000, and 5 Series MSO Series oscilloscopes. This probe offers up to 1 GHz of analog bandwidth with less than 3.9 pF of capacitive loading, ensuring accurate high-speed passive probing and minimal impact on the circuit under test.

2. Nøglefunktioner

• 1 GHz båndbredde: Capable of accurately measuring high-frequency signals.
• <4 pF Input Capacitance: Minimizes loading effects on the circuit under test.
• 10X Attenuation Factor: Extends the dynamic range of the oscilloscope.
• 300 V CAT II Input Voltage: Suitable for a wide range of applications.
• Compact Probe Head: Facilitates probing small-geometry circuit elements.

3. Opsætningsvejledning

Follow these steps to properly set up your TPP0500B oscilloscope probe:

1. Tilslutning til oscilloskop: Plug the TekVPI interface connector of the TPP0500B probe into an available TekVPI channel on your compatible Tektronix oscilloscope. Ensure a secure connection.
2. Fastgør jordledningen: Connect the ground lead (typically with an alligator clip) from the probe to the ground reference of the circuit you are testing. A stable ground connection is crucial for accurate measurements.
3. Select Probe Tip: Choose the appropriate probe tip for your application. The probe typically comes with various tips for different connection requirements.
4. Probekompensation: Before taking measurements, compensate the probe to match the input impedance of your oscilloscope. Connect the probe tip to the oscilloscope's probe compensation output (usually a square wave signal) and the ground lead to the compensation ground. Adjust the compensation trimmer on the probe (if present) until the square wave displayed on the oscilloscope is flat-topped, without overshoot or undershoot. Refer to your oscilloscope's manual for specific compensation procedures.

These accessories typically include a removable probe tip, a ground lead with an alligator clip, and colored identification rings for channel differentiation. The probe is designed for connecting to an oscilloscope to measure electrical signals.

4. Betjeningsvejledning

Once the probe is set up and compensated, you can begin taking measurements:

• Connect to Test Point: Carefully connect the probe tip to the desired test point on your circuit. Ensure a firm and stable connection.
• Observe Waveform: Adjust the oscilloscope's vertical and horizontal settings to display the waveform clearly. The 10X attenuation factor means the voltage displayed on the oscilloscope will be one-tenth of the actual voltage at the probe tip. Most modern oscilloscopes with TekVPI interfaces will automatically detect the probe and adjust the vertical scaling accordingly.
• Sikkerhedsforanstaltninger: Vær altid opmærksom på voltage limits of the probe (300 V CAT II). Do not exceed these limits. Ensure proper grounding of both the oscilloscope and the circuit under test to prevent electrical shock and ensure accurate readings. Avoid touching live circuit components with your hands or other conductive materials while probing.

5. Vedligeholdelse

Proper care and maintenance will extend the life and accuracy of your TPP0500B probe:

• Rensning: Use a soft, dry cloth to clean the exterior of the probe. If necessary, a cloth lightly dampened with isopropyl alcohol can be used. Avoid using harsh chemicals or abrasive materials. Ensure no liquid enters the probe body or connectors.
• Opbevaring: Store the probe in a clean, dry environment, preferably in its original packaging or a protective case, when not in use. Avoid exposing it to extreme temperatures, humidity, or direct sunlight.
• Håndtering: Handle the probe carefully. Do not bend the cable sharply or apply excessive force to the probe tip or connector. Avoid dropping the probe.
• Inspektion: Periodically inspect the probe cable, connectors, and tip for any signs of damage, such as cuts, cracks, or bent pins. Do not use a damaged probe.

6. Fejlfinding

If you encounter issues with your TPP0500B probe, consider the following:

• Intet signal eller svagt signal:
  • Ensure the probe is securely connected to both the oscilloscope and the circuit under test.
  • Verify the ground lead is properly connected.
  • Check the oscilloscope's input channel settings and vertical scale.
  • Confirm the circuit under test is powered and functioning correctly.
• Forvrænget bølgeform:
  • Perform probe compensation as described in the Setup section.
  • Check for damaged probe tips or cables.
  • Ensure the probe's bandwidth is sufficient for the signal frequency.
• Forkert bindtage-aflæsninger:
  • Verify the oscilloscope's vertical scale is correctly calibrated and set for a 10X probe. TekVPI probes usually auto-detect.
  • Ensure the probe is properly compensated.
