Distance To Fault
• power off the spectrum analyzer
• change the start frequency to a new value that lies below the start frequency of your
previous calibration
• change the stop frequency to a new value that lies above the stop frequency of your
previous calibration
• change any of the cables that you used for the calibration
• change any of the attenuators that you used for the calibration
• change the type of cable by selecting
None of the following calibrations are valid for Distance to Fault calibrations with
Frequency Range set to Auto:
• Distance to Fault calibrations performed with the Frequency Range set to Manual
• One Port Insertion Loss calibrations
• Two Port Insertion Loss calibrations
NOTE
Note also that Distance to Fault calibrations performed with the
Frequency Range set to Auto are not valid for any other measurement,
including Distance to Fault with the Frequency Range set to Manual.
Continue Use this key after you have made any desired changes to the calibration start or
stop frequencies, and you are ready to continue to the next step of the calibration.

Key Path
Calibration Start Freq Use this key to specify the Start Frequency of your calibration
frequency range. It is important that you keep the calibration frequency range as close as
possible to the actual sweep frequencies you intend using for the measurement or
measurements. For additional information, refer to
NOTE
The Calibrate Start/Stop frequencies define the frequency range over
which the CALIBRATION will take place, and do NOT define the
frequency range over which the MEASUREMENT will be made.
