Power Sensor Uncertainty Factors
The uncertainty factors, as a function of frequency for the Diode and Thermocouple,
Peak and Waveguide sensors, are listed in Tables 3-1, 3-2 and 3-3 respectively.
These values represent typical results based on factory test data unless otherwise noted.
The percent (%) column is the sum of all test system uncertainties including mismatch
uncertainties, the uncertainty of the standard sensor and transfer uncertainty which is
traceable to NIST ( National Institute of Standards Technology ). The probable
uncertainty ( % RSS ) is derived by the square root of the sum of the individual
uncertainties squared. % RSS is expressed with a coverage factor of 2 yielding a 95%
confidence level.
