ITU-T K.76-2008(預刊)電信網絡設備(9 kHz -150 kHz)的電磁兼容性要求

This Recommendation considers continuous electromagnetic phenomena from 9 - 150 kHz.Impulsive low frequency phenomena are considered in other K-series Recommendations.Continuous phenomena above 150 kHz are covered by Recommendation K.48 [1].Both the emissions and the immunity to induced signals at frequencies from 9 - 150 kHz are takeninto account in this Recommendation.This Recommendation defines test setup, measurement methods, emission limits and immunity testlevels for telecommunication network equipment.This Recommendation applies to all types of telecommunications network equipment. Due to thenature of the interference, the immunity test is applicable only to equipment having analogue voiceinterface that could be influenced by disturbing signals in the voice frequency range.
