  • Page 36: Compensating A Tpp0500B Or Tpp1000 Passive Voltage Probe

    Installation Compensating a TPP0500B or TPP1000 passive voltage probe Your Tektronix oscilloscope can automatically compensate TPP0500B and TPP1000 probes. This eliminates the need for manual probe compensation, as is typically performed with other probes. Each compensation generates values for a specific probe and channel combination. If you want to use the probe on another channel and desire to compensate the new probe-channel pair, you must run a new set of compensation steps for that new combination.
  • Page 37 NOTE. A probe compensation failure is most likely due to intermittent connection of the probe tip or ground connection during the probe compensation operation. If a failure occurs, the oscilloscope will re-use the old probe compensation values, if they existed prior to the failed probe compensation operation. MDO4000C Series Oscilloscope User Manual...

  • Page 38: Compensating A Non-Tpp0500B Or Non-Tpp1000 Passive Voltage Probe

Otherwise, to properly compensate your passive probe: Follow the steps for the functional check.

    Product description The P6616 general-purpose logic probe connects the Tektronix MDO4000C Series of mixed-signal oscilloscopes to digital buses and signals on your target system. The probe contains 16 data channels split between two lead sets (GROUP 1 and GROUP 2).

  • Page 202: Connecting The Probe To Your Circuit

    If you do not see an active signal, try another probe channel (or analog probe) to verify circuit activity at the test point. Typical application Use the P6616 probe to view digital signals on a system bus. Use an analog probe, such as the TPP0500B or TPP1000 passive probe, to view analog waveform information.
