Calibration Factor (CF) and Refl ection Coeffi cient (Rho)
Calibration Factor (CF) and Refl ection Coeffi cient (Rho) data is provided in the
Certifi cate of Calibration (CoC) that comes with the purchase of U2000 Series
USB power sensors. This data is unique to each sensor. If you have more than
one sensor, you should match the serial number on the CoC with the serial
number on the power sensor that you are using. The CF corrects the frequency
response of the sensor.
The Refl ection Coeffi cient (Rho, or r) relates to the SWR based on the following
formula:
Maximum uncertainties of the CF data are listed in the following tables.
As the U2000 Series USB power sensors have two independent measurement
paths (high and low power paths), there are two calibration factor uncertainty
tables for each sensor. The uncertainty analysis for the calibration of the sensors
is done in accordance with the ISO Guide. The uncertainty data reported on the
calibration certifi cate is the expanded uncertainty with a 95% confi dence level
and a coverage factor of two.
