*1 Total uncertainty includes contributions from Calibration Factor Uncertainty (CF), Linearity Uncertainty (L), Noise Uncertainty (N), Zero Offset Uncertainty (Z), Mismatch Uncertainty, and Temperature Uncertainty (T). All error terms must be converted to percentages for Total Uncertainty (RSS) calculation. Mismatch Uncertainty (Mm) requires knowledge of source match and should be expressed as a percentage using the equation Mm = 100 × [(1 ± Γsource × Γsensor)2 – 1].
*2 Use the following formula to determine Zero Offset Uncertainty as a percentage: Z = (Zero Offset Power / Nominal Power) × 100.
*3Nominal impedance = 50 Ω.
