Standard Uncertainties

Standard Uncertainty

Source

u_Pm

Power meter instrumentation uncertainty.

u_Pmc

Power meter instrumentation uncertainty (during calibration).

u_D

Power meter drift uncertainty.

u_Pcal

Calibrator output power level uncertainty.

u_Zs

Power meter zero set uncertainty.

u_N

Power meter and sensor noise uncertainty.

u_Zc

Power meter zero carryover uncertainty.

u_Mu

Mismatch gain uncertainty between the sensor and the generator. The standard uncertainty is dependent upon the reflection coefficients of the sensor and the generator.

u_Muc

Mismatch gain uncertainty between the sensor and the calibrator output of the power meter. The standard uncertainty is dependent upon the reflection coefficients of the sensor and the calibrator output.

u_Kc

Sensor calibration factor uncertainty at the frequency of the power meter calibrator output.
