I need to test some telecommunication ports for conducted emissions according to the methods in Annex C of EN55022:2010. I am testing floor-standing equipment.
The question I have relates to the figures shown in Annex C, vs. the test setup figures shown in the body of the standard (Figure 8, arrangement for floor-standing equipment). Figures C1, C2 and C3 in Annex C all show the EUT spaced 40cm from the groundplane [note 1 in the figure says "Distance to the reference groundplane (vertical or horizontal)"]. Figure 8 shows the EUT on an insulator (maximum 15cm thick) on the horizontal ground plane. Which figure governs the setup for telecommunication conducted emissions for floorstanding equipment, Figure 8, or Figures C1, C2, C3? I'm relatively new to testing telecom ports for conducted emissions, so is there some significance to the 40cm spacing show in Annex C? John D.
