Section F: Uncertainty

Efficiency Uncertainty Estimation

F.1 General Statement

Measurement uncertainty associated with the reported results was evaluated and estimated in accordance with JCGM 100:2008 (Guide to the Expression of Uncertainty in Measurement — GUM) and ISO/IEC 17025:2017, Clauses 7.6 and 7.2.

The uncertainty budget accounts for all significant identified contributors arising from the measurement process, instrumentation, test conditions, and operator interaction.

The reported expanded uncertainty U is obtained by multiplying the combined standard uncertainty uc by a coverage factor k = 2, corresponding to a confidence level of approximately 95 %, assuming a normal probability distribution.

Unless otherwise stated, the reported uncertainty applies only to the specific measurements performed and does not include long-term drift, aging effects, or future environmental changes.

F.2 Expanded Measurement Uncertainty by Measurement Type

Measurement Expanded Uncertainty U (k=2, norm)
Efficiency ±0.18%
Timings ±0.48ms
Power Excursions (Transient Response) ±0.1V
Conducted EMI Emissions (150 kHz – 30 MHz) ±2.35 dBμV
Noise Output ±1.23 dB
