Calibration factor and reflection coefficient
Calibration factor (CF) and reflection coefficient (Rho) data are unique to each sensor.
The CF corrects for the frequency response of the sensor. The Keysight EPM Series,
EPM-P Series, and P-Series power meters automatically read the CF data stored in the
sensor’s EEPROM and use it to make the corrections.
The reflection coefficient (Rho or ρ) relates to the SWR according to the following formula:
SWR =
1 + ρ
1 – ρ
Typical measurement uncertainties of the calibration factor (CF) are listed in the following
table. There is only one set of CF data used for both the high and low range of each sensor.
The typical measurement uncertainty data listed in the table is meant to help users on
the measurement uncertainty estimation. These values are only a guideline and are not to
be used in any accurate uncertainty calculations. For accurate measurement uncertainty
values, please refer to the measurement report
