The purpose of this test is to characterize the calibration factor of the power sensor at each frequency parameter. The calibration factor created will be used as the correction for the power measured.
A text file of the measured calibration factors will be generated in:
C:\Documents and Settings\All Users\Application Data\Agilent Technologies\Test Management Environment\{PowerSensorFamily}\{Model#}_{Serial#}.txt
It is recommended to use a clamp to hold the directional coupler during the test.
The power sensor (UUT) calibration factor uncertainty is stated as an absolute uncertainty. Stating calibration factor uncertainty as an absolute uncertainty allows for a consistent reporting format in TME.
Calibration factor uncertainty can be stated as a relative or an absolute number. Traditionally, calibration factor uncertainty has been stated as a relative number. Measurement uncertainty calculations require that this parameter be a relative term. It is critical that this distinction between absolute and relative uncertainties be understood when performing measurement uncertainty calculations. The power sensor (UUT) relative calibration factor uncertainty can be derived from the absolute calibration factor uncertainty by the following equation:
Relative calibration factor uncertainty = 100% × (Absolute calibration factor uncertainty) / (Calibration factor)
In general, the difference between the relative and absolute uncertainty is less than 10%. This small difference is because calibration factor values tend to be greater than 90% on a typical power sensor.
The cal factor uncertainty of the Standard Power Sensor is the most significant contributor to the overall measurement uncertainty of the calibration factor test. Other factors, such as the mismatch and the repeatability of the test system are significant; however, choosing an appropriate reference power sensor is critical to the reported calibration factor uncertainty.
TME recommends using a Standard Power Sensor with Option H84. H84 sensors are calibrated at the required cardinal frequencies using the Standards Lab calibration service. This provides the lowest possible uncertainty.
The calibration factor uncertainty of the 8485D UUT depends on the calibration factor uncertainty of the 8485D Standard Power Sensor. The calibration factor uncertainty of the Standard Power Sensor is smaller when calibrated by itself than when calibrated with the 11708A 30dB reference attenuator. To meet the Maximum Calibration Factor Uncertainty Specification of the UUT, it is recommended to have the Standard Power Sensor calibrated by itself without the reference attenuator. Ask your service provider to calibrate the 8485D Standard Power Sensor and reference attenuator separately.
