Calibration Factor (CF) and Reflection Coefficient (Rho)

Calibration Factor and Reflection Coefficient data are provided at frequency intervals 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.
The EPM series power meter automatically reads the CF data stored in the sensor and uses it to make the corrections.

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

SWR =(1 + Rho)/(1 - Rho)

Maximum uncertainties of the CF data are listed in Tables 13A and 13B. As the E-series E9300 power sensors have two in-
dependent measurement paths (high and low power paths), there are two calibration factor uncertainty tables. The uncer-
tainty analysis for the calibration of the sensors was done in accordance with the ISO Guide. The uncertainty data report-
ed on the calibration certificate is the expanded uncertainty with a 95% confidence level and a coverage factor of 2.
