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.
When display mode is chosen, the frequency you entered and the
sensor table identifier is displayed in the upper window. Also, pressing ,
displays the frequency you entered and calibration factor for each channel derived from the
selected sensor tables.
