Procedure of Preliminary Test 
Radiated emission tests shall be made with the receive or transmit antenna located at a 
horizontal distance of 3 m plus half of the maximum width of the EUT being tested, 
measured from the centre of the EUT. The tests shall be performed with the equipment 
configured as closely as possible to its typical, practical operation. Unless stated otherwise, 
cables and wiring shall be as specified by the manufacturer and the equipment shall be in its 
housing (or cabinet) with all covers and access panels in place. Any deviation from normal 
EUT operating conditions shall be included in the test report. 
The EUT (on a non-conductive support structure, where applicable) shall be placed on a 
remotely operated turntable, to allow the EUT to be rotated. The height of the EUT above 
the ground plane shall be according to the following requirements. 
• Table-top equipment is placed on a non-conductive set-up table with height 0,8 m ± 0,01 
m, CISPR 16-1-4 specifies the method to determine the impact of the non-conductive set-up 
table on test results. 
• Floor-standing equipment is placed on a non-conductive support, as specified in the 
applicable product standard. If there are no EUT height placement requirements in the 
product standard, the EUT shall be placed on a non-conductive support at a height of 5 cm 
to 15 cm above the ground plane. 
Interface cables, loads, and devices should be connected to at least one of each type of the 
interface ports of the EUT and, where practical, each cable shall be terminated in a device 
typical for its actual use. Where there are multiple interface ports of the same type, a typical 
number of these devices shall be connected to devices or loads. It is sufficient to connect 
only one of the loads, provided that it can be shown, for example by preliminary testing, 
that the connection of further ports would not significantly increase the level of disturbance 
(that is, more than 2 dB) or significantly degrade the immunity level.   
The test mode(s) described in Item 2.4 were scanned during the preliminary test. After the 
preliminary scan, we found the test mode described in Item 2.4 producing the highest 
emission level. The EUT and cable configuration, antenna position, polarization and
