3.6 Measurement Uncertainty
The measurement uncertainty describes the overall uncertainty of the given measured value
during the operation of the EUT.
Measurement uncertainty is calculated in accordance with CISPR 16-4-2: 2003.
Measurement uncertainty of mains terminal disturbance voltage :
Measurement uncertainty of mains terminal disturbance voltage :
± 3.6dB
The measurement uncertainty is given with a confidence of 95%, k=2.
3.7 Additions, Deviations and Exclusions from Standards
None.

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.

4.3 Test Setup and Test Procedure
The disturbance power was measured with the EUT in a shielded room.
The EUT was placed on a non-metallic table at least 0.4m from other metallic surface and the
The EUT was placed on a non-metallic table at least 0.4m from other metallic surface and the
mains lead of EUT was extended to about 6m long. The absorbing clamp was moved along the lead to
obtain maximum disturbance.
obtain maximum disturbance.
The EUT was set to achieve the maximum emission level, and for each point which appears a
relevant high emission level, the absorbing clamp was moved around the lead to get the maximum
disturbance value.
disturbance value.
The bandwidth of test receiver was set at 120kHz.
The frequency range from 30MHz to 300MHz was checked.
Amplitude measurements were performed with a quasi-peak detector and, if necessary, with an
average detector.
