E-Series average power sensor specifications (continued)
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 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 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 12a and 12b, for each
individual measurement path (high power
and low power, as shown 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.
