Service personnel use the factory calibration

external sources. Contact your Tektronix

NOTE.
Signal Path Compensation does not include calibration to the probe tip. (See page 13, Compensating a
non-TPP0250, non-TPP0500B or non-TPP1000 Passive Voltage Probe.)
Signal Path Compensation for Frequency Domain Only
The signal path compensation (SPC) described above runs on both the time and the frequency domain inputs. If you only
want to compensate the RF input, you can save time by running SPC only on the RF input and skipping the time domain
part. You can do this as follows:
1.
As with the time and frequency calibration,
warm up the oscilloscope for at least
20 minutes. Remove all input signals
(probes and cables) from the RF input.
