E-Series power sensor specifications

The E-Series of power sensors have their calibration factors stored in EEPROM and operate over a wide dynamic range. They are designed

for use with the EPM Series of power meters and two classes of sensors are available:

 CW power sensors (E4412A and E4413A).

 Average power sensors (E9300 sensors).

E-Series CW power sensor specifications

Calibration factor (CF) and reflection coefficient (Rho)

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 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 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.
