If the measurement frequency does not correspond directly to a
frequency in the sensor calibration table (if selected) and the
frequency dependent offset table being used, the power meter
calculates the calibration factor and offset using linear
interpolation.
If you enter a frequency outside the frequency range defined in the
sensor calibration table or the frequency dependent offset table,
the power meter uses the highest or lowest frequency point in the
appropriate table to set the calibration factor and offset.
The value of the calibration factors being used by the power meter
to make a measurement is displayed under the
softkeys.
