Calibration factor and reflection
coefficient
Calibration factor (CF) and reflection
coefficient (Rho) data is unique to each
sensor. The CF corrects for the frequency
response of the sensor. The reflection
coefficient (Rho or ρ) relates to the SWR
based on the following formula:

Maximum uncertainties of the CF data are
listed in the following table. There is only
one set of CF data used for both high and
low power paths of each sensor.
The uncertainty analysis for the
calibration data was done in accordance
with the ISO Guide. The uncertainty data
reported on the calibration certificate
is the expanded uncertainty with a 95%
confidence level and a coverage factor
of 2.
