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 of the power sensor you are using. The CF corrects for the frequency response
of the sensor. The EPM-P series power meter automatically reads the CF data stored in
the sensor and uses it to make corrections.
For power levels greater than 0 dBm, add to the calibration factor uncertainty
specification:
± 0.1%/dB (for E9321A and E9325A sensors),
± 0.15%/dB (for E9322A and E9326A sensors) and
± 0.2%/dB (for E9323A and E9327A sensors).
Reflection Coefficient (Rho) relates to the SWR according to the formula:
SWR = (1 + Rho) / (1 – Rho)
Maximum uncertainties of the CF data are listed in Table 7. The uncertainty analysis for
the calibration of the sensors 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.
