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