5.2 Test set-up
The EUT was placed on a non-metallic table of height 0.8m. At the side of the EUT a non-metallic table of length 6m was
placed to provide for movement of the absorbing clamp. The absorbing clamp was applied successively to all leads whose
length was 25cm or longer, unscreened and screened. For each read the maximum measured value at each frequency which
was obtained when the absorbing clamp is moved along the lead the distance specified is to be registered. No metallic
object, including a possible other unit than 0.8m.
All screened and unscreened cables were measured with an absorbing clamp, according EN 55013- 5.6.
The test set-up photo is included in appendix I.
5.3 Measurement uncertainty
Disturbance power, quasi-peak detection
: ± 3.1dB
Disturbance power, average detection
: ± 3.1dB
The measurement uncertainty describes the overall uncertainty of the given measured value during operation of EUT in the
above-mentioned way.
