As the upper frequency of the test signal is 80 MHz, EUT size may be considerable compared to the wavelength, and resonance effects may be present with cables that are connected to such EUTs.In this case, this annex provides an alternative test method applicable to large EUTs that places the coupling device near to the cable entry, resulting in a small loop area with reduced resonance effects.Examples of large EUTs to which this annex may apply include, but are not limited to, the following.– rack-mounted telecommunication switching systems;– electrical machinery;– rack-mounted switch and control gear.F.1 Test set-up for large EUTsExamples of the test set-up for large EUTs are given in Figures F.1 and F.2.The elevated ground reference plane shown in Figure F.1 is the reference ground plane for this test set-up. The purpose of the elevated ground reference plane is to reduce the length of cable between the EUT and CDN, thereby controlling or reducing the effects of resonances in the cables.The size of the elevated ground reference plane shall be large enough to extend a minimum of 0,2 m beyond all CDNs used in the test. The length of cable under test between the EUT and CDN shall be a maximum 0,3 m.The elevated ground reference plane shall be placed at a height above the main ground plane so that to allow cables from the EUT to pass to the CDNs in a horizontal alignment.The elevated ground reference plane shall be electrically connected to earth for safety reasons. This connection is not significant from an RF point of view.NOTE 1 Attention should be taken with the physical construction of the elevated ground reference plane and its support structure to ensure a mechanically safe condition.The equipment to be tested should be placed on an insulating support of 0,1 m height above the ground plane. In case the equipment is delivered on a transport pallet, and if due to its excessive weight or size it cannot be safely removed from its transport pallet, then the EUT may be left on its pallet for testing even if its height exceeds 0,1 m. In case the equipment, because of size or weight, cannot be elevated 0,1 m, thinner insulation may be used provided the EUT is electrically isolated from the ground plane. Any variation from the standard method of testing shall be recorded in the test report.The AE may be located on the elevated ground reference plane but does not need to be located on it provided the AE is connected to the EUT via a CDN. When direct injection is used, the AE may be located off of the elevated ground reference plane provided proper decoupling is used. In the case where clamp injection is used instead of injection via a CDN, the AE must be located on the elevated ground reference plane.Figure F.1 – Example of large EUT test set-upwith elevated horizontal ground reference planeThe vertical ground reference plane shown in Figure F.2 is the reference ground plane for this test set-up. The purpose of the vertical ground reference plane is to reduce the length of cable between the EUT and CDN, thereby controlling or reducing the effects of resonances in the cables.NOTE 2 The vertical ground reference plane may be more applicable than the horizontal elevated ground reference plane in cases where cables enter/exit the EUT at multiple heights.The vertical ground reference plane shall be electrically connected to earth for safety reasons. This connection is not significant from an RF point of view.The size of the vertical ground reference plane shall be large enough to extend a minimum of 0,2 m beyond all CDNs used in the test. The length of cable under test between the EUT and CDN shall be a maximum 0,3 m. The distance between the EUT and the vertical ground reference plane shall be such that the 0,3 m cable length requirement can be satisfied. A wall of a shielded room can be used as the vertical ground reference plane.The CDNs shall be mounted to the vertical ground reference plane at a height that allows cables from the EUT to pass to the CDNs in a horizontal alignment.The statements given for the test set-up using a horizontal elevated ground reference plane (i.e., insulating support and location of AE) apply for the test set-up using a vertical ground reference plane accordingly.Figure F.2 – Example of large EUT test set-up with vertical ground reference plane___________ISBN 2-8318-XXXX-XTypeset and printed by the IEC Central OfficeGENEVA, SWITZERLAND。
