4.5 Measurement Uncertainty
The measurement uncertainty describes the overall uncertainty of the given measured
value during the operation of the EUT.
Measurement uncertainty at mains terminal:
value during the operation of the EUT.
Measurement uncertainty at mains terminal:
± 1.99dB
The measurement uncertainty is given with a confidence of 95%, k=2.
The measurement uncertainty is traceable to internal procedure TI-036.
The measurement uncertainty is traceable to internal procedure TI-036.

Note: 1. * means the limit increasing linearly with the frequency.
2. If the limit for the measurement with the average detector is met when
using a receiver with a quasi-peak detector, the equipment under test shall
be deemed to meet both limits and the measurement with the receiver with
average detector need not be carried out.
