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 factor being used by the power meter to make a measurement
is displayed under the
softkey.
