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.
