8.2. Test set-up and procedure
The EUT was placed on a non-metallic table of 0.8m height. At the side of the
EUT a non-metallic table of 6m length was placed to provide for movement of
the absorbing clamp. The absorbing clamp was applied successively to all leads
whose length was 25 ㎝ or longer, unscreened or screened. For the read, the
maximum measured value at each frequency which was obtained when the
absorbing clamp is moved along the lead was registered. No metallic object,
including a possible other unit of the EUT or any person, was closer to the lead
or unit than 0.8m. All screened and unscreened cables were measured with an
absorbing clamp, according to EN55013, 5.6.

8.3. Measurement uncertainty
Radio interference power: ±2.0 ㏈
The Measurement uncertainty describes the overall uncertainty of the given
measured value during operation of the EUT in the above-mentioned way.

8.5. Test protocols
Date: January 10, 2008
The equipment does comply with the requirements. Operating condition: The
EUT continuously operated with audio frequency of 1,000 ㎐ color bar being
supplied from the Oscillator or test DVD. An absorbing clamp was placed
around all leads. At each mode, the maximum value at each testing frequency
and each output lead was registered and attached as follows.

to
EN55013:2001+A2(2006)
Note:1) The spectrum was checked from 30 to 300 ㎒.
2) The cable (6.0m length) loss is included in a correction factor.
3) Detector function of the measuring instrument:
QP: Quasi-peak, AV: Average
4) QP line: Limit (㏈㎺) = Frequency (㎒) ×0.037 + 43.9
AV line: Limit (㏈㎺) = Frequency (㎒) ×0.037 + 33.9
5) *: Less than 25 ㏈㎺
