Calibration factor and reflection
coefficient data are provided at 1 GHz
increments 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 Certificate of Calibration (COC)
with the serial number on the power
sensor you are using. The CF corrects
for the frequency response of the sensor.
The EPM power meter automatically
reads the CF data stored in the sensor
and uses it to make the corrections.
For power levels greater than 0 dBm,
add 0.5%/dB to the calibration factor
uncertainty specification.
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 Table 5a, for the E4412A
power sensor, and Table 5b for the
E4413A power sensor. The uncertainty
analysis for the calibration of the sensors
was done in accordance with the
ISO/TAG4 Guide. The uncertainty data
reported on the calibration certificate is
the expanded uncertainty with a 95%
confidence level and a coverage
factor of 2.
