4.3 Measurement Uncertainty
Test Item Measurement Uncertainty
Conducted Emissions at AC Power Line (150kHz-30MHz)
± 3.0dB (150kHz to 30MHz)
Duty Cycle
± 0.37%
99% Bandwidth
± 3%
26dB Emission bandwidth
± 3%
Minimum 6 dB bandwidth (5.725-5.85 GHz band )
± 3%
Maximum Conducted output power
± 0.75dB
Peak Power spectrum density
± 2.84dB
Radiated Emissions (Above 1GHz) ± 4.8dB
Radiated Emissions which fall in the restricted bands
± 4.5dB (below 1GHz); ± 4.8dB
(above 1GHz);
Frequency Stability
± 7.25 x 10-8
Radiated Emissions (Below 1GHz)
± 4.5dB
Remark:
The U
lab
(lab Uncertainty) is less than U
cispr
(CISPR Uncertainty), so the test results
– compliance is deemed to occur if no measured disturbance level exceeds the disturbance limit;
– non-compliance is deemed to occur if any measured disturbance level exceeds the disturbance limit.
