Power data correction is performed as follows. (The correction value is Corr shown below.)
Data after correction (dBm) = data before correction (dBm) + Corr (dB)
If the power data frequency to be corrected is smaller than the minimum frequency in the loaded data, the correction coefficient for the minimum frequency is used for correction.
If the power data frequency to be corrected is greater than the maximum frequency in the loaded data, the correction coefficient for the maximum frequency is used for correction.
If the power data frequency to be corrected does not match any frequency in the loaded data, the correction coefficient obtained by linear interpolation of the nearest 2 points is used for correction.
In this case, a correction coefficient after linear interpolation (Corr') is used for calculation.
Data after correction (Watt) = data before correction (Watt) x correction value (Corr')
Corr' = 10 ^ (Corr / 10)
Note that correction is made before determining raw data. In other words, corrected values are stored as raw data. For more information on raw data, see Internal data processing in Reading/writing measurement data.
