Interpolation and Extrapolation
The analyzer can interpolate and extrapolate power correction data so that a source or receiver power
calibration can be reused after a change of the frequency sweep range:
 At new sweep points within the calibrated sweep range, interpolation is applied to calculate the
correction data. A label PCai in the trace list indicates an interpolated power calibration.
 At new sweep points outside the calibrated sweep range, the correction values are extrapolated:
Sweep points below the lowest calibrated frequency are assigned the correction value of the
lowest frequency. Sweep points above the highest calibrated frequency are assigned the
correction value of the highest frequency. A label PCax in the trace list indicates an extrapolated
power calibration.
Power Corr All Ports On
Applies all available source and/or receiver power calibrations to the active channel. This function is
disabled if no power correction data has been acquired for the active channel.
Uncheck the ...Power Correction Off boxes in the Source Power Cal and Receiver Power Cal dialogs
to enable an individual source or receiver calibration. The settings are also accessible from the Port
Configuration dialog. Press Power Corr All Ports Off to disable the power calibration of all sources and
receivers.
The checkmarks next to the Power Corr All Ports On / Off menu commands indicate the power calibration
state of the active channel:
 If Power Corr All Ports On is checked, the power calibration of the active channel is applied
without exceptions.
 If Power Corr All Ports On is checked, the power calibration of the active channel is not applied.
 If none of the commands is checked, the power calibration of the channel is applied but one or
several source or receiver power calibrations have been disabled (Source Power Cal / Receiver
Power Cal / Port Configuration dialogs).

Power Corr All Ports Off
Disables all source and receiver power calibrations of the active channel so that all power correction data
is ignored. This function is disabled if no power correction data has been acquired for the active channel.
Check the ...Power Correction Off boxes in the Source Power Cal and Receiver Power Cal dialogs to
disable an individual source or receiver calibration. The settings are also accessible from the Port
Configuration dialog. Press Power Corr All Ports On to re-enable the power calibration of all sources and
receivers. For more information refer to the description of Power Corr All Ports On.
