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 |
