This part of EN 50289-1 details the method of in field test to determine the coupling attenuation for installed links and channels used in analogue and digital communication systems. It is to be read in conjunction with EN 50289-1-6 and EN 50289-1-15. This method is used to determine the attenuation of disturbing power to signal power in a cabling system, and vice versa. This determines the influence from cabling on the EMC performance of a system. NOTE 1 The coupling attenuation of installed links and channels is dependant upon the performance of the cabling components (balance and screening if applicable), workmanship (especially termination of screens) and earthing and grounding. This procedure determines the overall effect of these parameters. NOTE 2 This method cannot be used for verification of compliance with emission and immunity EMC standards for the complete system including active components
