11.3 Test set-up
<Floor standing>The EUT was placed on a non-metallic support 0,1m above a reference ground plane
(RGP) and was put into operation according to the specified operating mode.
<Table top>A horizontal coupling plane (HCP) was placed on a 0.8m high non-metallic table above a
2.6m by 1.8m reference ground plane (RGP) and connected to it through a cable with two 470k

(RGP) and was put into operation according to the specified operating mode.
<Table top>A horizontal coupling plane (HCP) was placed on a 0.8m high non-metallic table above a
2.6m by 1.8m reference ground plane (RGP) and connected to it through a cable with two 470k
Ω
resistors at each end. The EUT was placed on an insulation sheet on the HCP and was put into operation
according to the specified operating mode.
A vertical coupling plane (VCP) was connected to the RGP through a cable with two 470k
according to the specified operating mode.
