Calibration Factor and Reflection Coefficient

Calibration Factor (CF) and Reflection Coefficient (Rho) data are provided on a data sheet included with the power sensor. This data is unique to each sensor. If you have more than one sensor, match the serial number on the data sheet with the serial number on the power sensor you are using. The CF corrects for the frequency response of the sensor. Agilent EPM series power meters automatically read the CF data stored in the sensor and use it to make the corrections.

Reflection Coefficient (Rho, or ρ ) relates to the SWR according to the following formula:

1 + ρ SWR = ------------

1 – ρ

Maximum uncertainties of the CF data are listed in the following tables. As the Agilent E-series E9300 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 was done in accordance with 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.
