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 fol-
lowing formula:
SWR =
1 + ρ
1 – ρ
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 cali-
bration data was done in accordance
with the ISO Guide. The uncertainty
data reported on the calibration cer-
tificate is the expanded uncertainty
with a 95% confidence level and a
coverage factor of 2.
